Compare all eSIM plans in Montenegro

How we got these numbers: we read 81 public customer reviews that mention Montenegro or a place in it, published between June 2024 and August 2026, and counted a report as "worked" when the reviewer said the eSIM connected, even with small hiccups. We treat 20 or more reports as strong evidence, 3 to 19 as limited, and fewer than 3 as too few to judge. A count like 12 of 14 means the eSIM worked well for 12 of the 14 travelers who reported from here; each provider section says what went wrong for the rest. The Vefru test score is a separate number: our own hands-on test of the provider, run outside Montenegro, so it says how the provider behaves, not how the network performs here. Local operator prices in the text were checked on 26 September 2026; provider ratings, the plan tables and the price-per-GB chart are live and update on their own.

We ranked providers by traveler reports from Montenegro first, price second and our hands-on tests third. No provider reaches the 20 reports we count as strong evidence, so every record below is limited. The Best group is the five providers with the strongest records and three or more reports, plus eSIM4Travel, which stays in the group on price position and test results even with only two reports.

Global YO eSIM in our hands

Go to Global YO website View full review

Global YO suits travelers who install the eSIM at home and want low-priced data on a longer stay, and it had the cleanest record here: it worked well for 3 of 3 travelers who reported from Montenegro. Three reports is limited evidence, so treat it as a good sign, not proof. The reports date from 2024 and 2025. One traveler used it from Belgrade through Sarajevo and Mostar into Montenegro and called the network "superb even on the mountains and rough terrains" (2 Jul 2024). Another needed one eSIM for Montenegro, Czechia and Hungary.

None of the three reports describes a miss, so there are no failures to learn from. What we could not confirm is the network: our research could not confirm which operator Global YO uses in Montenegro. One reviewer's tip from April 2025 is to install the eSIM before you travel, then switch it on and turn on data roaming when you arrive.

Global YO sells Montenegro plans from 1 GB to 100 GB over 3 to 60 days, day plans with a daily allowance, and Europe and global plans that also list Montenegro. It has no unlimited plan. In our hands-on test it was among the two cheapest providers in our comparison, but purchase is app-only and support was slow to answer, so it suits people who will not need the help desk. Our Global YO review has the details.

Holafly is an Irish eSIM provider built around unlimited data, with trip eSIMs for 200+ destinations. Travelers report it working more often than any other provider we track. Its weak points are speed and price: our test ran at about 30 Mbps on 5G, and its unlimited plans cost more than most.

Holafly eSIM in our hands

Go to Holafly website View full review

Holafly suits travelers on a Balkan road trip who want unlimited data without counting gigabytes, and it worked well for 9 of 10 travelers who reported from Montenegro (limited evidence). The catch is speed: in our test, Holafly's speed was capped from the start. That is enough for maps, messaging, browsing and streaming, but slow for large downloads, uploads, cloud backups and laptop work. The successes include a Balkan eSIM used across Albania, Kosovo and Montenegro, and a traveler who said it worked superbly on mountain roads in June 2026.

The one miss, from 29 Jul 2026, was slow data: the connection was mostly there, but too slow to run Google Maps, even in Tivat, and the reviewer spent three days trying to reach a person through support bots. Two other reviewers, at 4 and 5 stars, also mention poor speed or coverage in Montenegro. The reviews do not say whether the speed cap was the cause. One traveler's Europe plan did not cover Montenegro, and a one-day Montenegro plan fixed it.

Holafly's own page lists three networks for Montenegro, MTEL, One and Crnogorski Telekom (checked September 2026). Its plans are unlimited by the day, from 1 to 30 days, with the hotspot capped at 1 GB a day and no top-ups (you buy a new eSIM). It is usually among the dearest unlimited options in our comparison. Our comparison tool listed no Holafly plan for Montenegro at export time, so there is no plan table here; check the Holafly page for current plans. Our Holafly review covers the speed test.

GoMoWorld is the travel eSIM brand of Irish operator eir, with plans in 202 countries. Every destination has the same four euro prices, and we saw no throttling at all. The catch is that everything happens in the app, and human support works only in office hours.

GoMoWorld eSIM in our hands

Go to GoMoWorld website View full review

GoMoWorld suits travelers who want large data allowances and fast, unthrottled data on the coast and in the hills, and it has the largest evidence base here: it worked well for 12 of 14 travelers who reported from Montenegro (86%). Reviewers describe "great signal all over Montenegro" (2 Aug 2026), a connection from the moment they arrived, and service in the mountains (Apr 2026). One reviewer named Tivat, Budva and Kotor as all connected (1 Jul 2026).

The two misses were different problems. One traveler said the eSIM worked in Bosnia but not in Montenegro until the border, and said he was billed twice for Albania. The other bought a 30-day, 15 GB plan that ended after 7 days because the data ran out, and got no further explanation from chat. Several happy reviewers also mention setup hiccups: the plan only starts when you press Start in the app, which is a common cause of "not working".

GoMoWorld sells four Montenegro plans of 3, 15, 30 and 45 GB with tethering and 5G listed, no unlimited plan and no calls. Its page does not name the network, so we could not confirm which operator it uses. In our test (run in Austria) it was the fastest provider, with no sign of throttling; the drawbacks are app-only delivery with no QR code, and help desk staff only in office hours. Prices are usually below the market average, and best value on larger plans. See the GoMoWorld review, or go to GoMoWorld.

Airalo eSIM in our hands

Go to Airalo website View full review

Airalo suits first-time buyers who want a simple purchase and install, and it worked well for 5 of 6 travelers who reported from Montenegro (limited evidence). The good reports are short and alike: easy to install, works on arrival, simple to top up. A traveler on a second visit wrote that "it works to perfection" (5 Aug 2026).

The miss was an unlimited plan: a reviewer says a 5-day unlimited eSIM worked on the first day and then stopped, as it had before in Georgia and Bratislava, with plenty of data and time left (Jul 2026). Another traveler says he reported connectivity problems in Montenegro in Nov 2025 and nothing was done until he returned in Jun 2026, when WhatsApp support fixed it in 48 hours. A third warns that Europe and Global plans differ: the Global plan with calls and texts had no coverage in Bosnia, although the Europe plan listed it.

Airalo's own page lists MTEL as its Montenegro network (checked September 2026). It sells Montenegro plans from 1 GB to 50 GB and unlimited plans from 3 to 30 days, which slow after 3 GB a day, plus Europe and global plans; calls and texts exist only on some global plans. In our test, install was easy and support average. Its price is at the market average, never the cheapest, and across all countries it has the weakest traveler-report record of the 14 providers we track. Read our Airalo review or visit Airalo.

Yesim eSIM in our hands

Go to Yesim website View full review

Yesim suits experienced travelers who want unlimited data sold by the day, and it worked well for 5 of 7 travelers who reported from Montenegro (71%, limited evidence). Our city-level data places both misses in Budva and Kotor, one each. The reports we hold for Yesim do not say what went wrong.

The pattern matches other providers: Budva and Kotor are where GigSky, Maya and Yesim all had misses, so the coast looks like the weak spot on some networks. Yesim's own page lists MTEL and a Telekom network for Montenegro (page snippet read in September 2026), but an older Yesim blog post lists Telenor and T-Mobile, so we treat its network as unconfirmed.

Yesim sells Montenegro plans of 500 MB to 30 GB and unlimited plans for any length from 1 to 30 days (partner throttling, limit not published), plus Balkans and global bundles. In our test, support was among the slowest (15 to 60 minutes per reply), the plan started at purchase rather than at first use, so it is best bought close to the trip, and the app nags with upsells. Its fixed plans are among the dearer ones; unlimited is priced at market. Read the Yesim review or go to Yesim.

eSIM4Travel eSIM in our hands

Go to eSIM4Travel website View full review

eSIM4Travel suits travelers who want the lowest price and a human help desk, and who do not need an app. Only 2 reports exist from Montenegro so far, both positive, which is too few to judge. One traveler used a one-day plan on a 5G connection, and another used it in Portugal, Montenegro and France and said support was swift when an install failed.

There are no misses yet. The open question is the network: eSIM4Travel's plans are listed as MTEL, and its homepage names MTEL too (page snippet read in September 2026). MTEL has the most subscribers [1], but the networks section shows Crnogorski Telekom leading on speed and coverage, so a weak spot on the coast is a risk we cannot rule out.

eSIM4Travel sells Montenegro plans from 100 MB to 20 GB, unlimited plans from 3 to 30 days that slow after a daily allowance, tethering, and Europe and global plans that also list Montenegro; validity starts at the first connection. In our test the help desk was the best we saw: one click from the bot to a person who solved the problem. It is usually the cheapest provider in our comparison, and for 2 GB to 5 GB plans in Montenegro too. The drawbacks are no app, no Google Pay, and no way to top up without Wi-Fi once the data runs out. Our eSIM4Travel review has the test.

Other eSIM Providers for Montenegro

These eight providers are tested by us but sit outside the Best group, because their record in Montenegro is thinner or weaker, or because a finding from our tests counts against them. Five have only one or two traveler reports. We still list each one with what the files show, so you can see why it is not a top pick here.

Maya Mobile eSIM in our hands

Go to Maya Mobile website View full review

Maya suits long, multi-country trips with heavy data use, but its Montenegro record is mixed: it worked well for 12 of 17 travelers who reported from here (71%, limited evidence). The successes are mostly short, happy reviews from people who used Maya in several countries. One wrote "It worked perfectly in Montenegro" (19 Nov 2025). Two reviewers who had problems got refunds and rated the help desk well.

The negative reports describe the same fault: a signal on screen and nothing loading. A group of three had no internet more than half the time in Kotor, Budva, Podgorica and near Žabljak (10 Sep 2025). Another traveler had no signal most of the time in Kotor (10 Sep 2025). Three more describe plans that failed in the country or at the border: a Balkan package that was unusable in Montenegro, Albania and Bosnia (4 Sep 2025), a Europe plan that stopped when the traveler left Croatia (28 Jun 2025), and 3G without 5G in Montenegro and Albania (10 Oct 2025).

Maya sells no Montenegro plan in our comparison tool, only global unlimited plans of 3 to 30 days that slow after 5 GB a day. In our test that was the fairest unlimited rule we saw, and it is the cheapest global unlimited plan we compared. We could not confirm which network Maya uses here. The drawbacks are template replies from the help desk and nothing for small or short needs. Read our Maya Mobile review for the test, or visit Maya.

Nomad eSIM in our hands

Go to Nomad website View full review

Nomad suits experienced users who can sort out problems alone, but in Montenegro it worked well for only 8 of 15 travelers who reported (53%, limited evidence), the lowest share of any provider with 10 or more reports here. The successes are short and warm: "Always had great connection wherever we were in Montenegro" (8 Jun 2026). One traveler's 5 GB plan ran out in 2 days (5 Aug 2026), so small plans are a risk for heavy users.

Most of the seven misses are slow or unusable data with a full signal. A 20 GB plan loaded nothing on 5G (13 Jul 2026). Another traveler could text but not use Google Maps or online banking (1 May 2026). A Balkans eSIM was "hopeless" in Montenegro (19 May 2026), and a 4-star reviewer saw the same trouble even around larger towns on LTE or 5G, though not in six other countries on the trip (29 May 2026). Two misses were different: two eSIMs could not be installed from the email (20 Jul 2026), and a traveler found that the Europe eSIM leaves out Montenegro, bought two Montenegro eSIMs and could not use them (15 May 2026).

Nomad sells Montenegro plans of 1 GB to 50 GB over 3 to 30 days, and unlimited plans of 3 to 10 days that slow after 2 GB a day. Our comparison tool lists them as m:tel. In our test the app was good, with a remaining-data widget on the home screen, and prices sit just below the market. The help desk was the weak point: a bot looped with no route to a person.

ByteSIM eSIM in our hands

Go to ByteSIM website View full review

ByteSIM suits experienced users who want a very wide choice of plan types. It worked well for 2 of 2 travelers who reported from Montenegro, which is too few to judge. One used it for 7 days "without any problem" (31 Dec 2025). The other's eSIM stopped working at some location, and the WhatsApp help desk restored the settings after some confusion, because the phone held more than one eSIM (25 Oct 2024).

ByteSIM sells Montenegro plans of 500 MB to 90 GB, daily plans of 500 MB to 3 GB a day, and unlimited plans of 1 to 30 days, with validity from 1 to 30 days and no top-ups. Its own page lists MTEL as the network and says no ID or registration is needed (as of September 2026). The same page claims MTEL is the most reliable network and cites EKIP, the Montenegrin regulator, but we found no EKIP data that supports that. In our test the checkout was clumsy, the app was a wrapped website, and the help desk did not answer on WhatsApp within 15 minutes, though customers report fast replies. It has the lowest Vefru test score of the 14 providers, and its price sits at the market. See our ByteSIM review or ByteSIM.

Roamless suits light users who cross several countries on one eSIM. It worked well for 1 of 1 travelers who reported from Montenegro, which is too few to judge. That traveler used it for a week in Montenegro, then in Japan, China and Mexico, and wrote "Very reliable for the coverage" (21 Oct 2025). There are no reported misses, so we have no failure pattern to describe.

Roamless is one global eSIM. For Montenegro it lists 30-day plans from 1 GB to 50 GB and a pay-as-you-go credit that does not expire, plus a free Montenegro plan. It sells no unlimited plan, claims no throttling and allows unlimited hotspot use. Our comparison tool lists the network as Mtel, and Roamless's page also names a "T-Mobile" network (reported). In our test the plan needed a manual fix to the APN setting, the eSIM could only be bought in the app, and the human help desk solved it in 29 minutes. Price sits at the market: low for 1 GB, high above 10 GB. See our Roamless review or Roamless.

Saily is the travel eSIM from the company behind NordVPN, with plans for about 200 destinations. It has the smoothest install we have tested, a polished app and a built-in VPN. But prices run above the market in most big European destinations, and traveler reports sit below average.

Saily eSIM in our hands

Go to Saily website View full review

Saily suits first-time buyers who want the easiest app and the fastest help desk and accept a higher price. It worked well for 1 of 1 travelers who reported from Montenegro, which is too few to judge: "No issues in Montenegro!" (20 Aug 2026). The same reviewer praised the quick reply from customer service. There are no misses on record.

Saily sells Montenegro plans of 1 GB for 7 days and 3, 5, 10 and 20 GB for 30 days. Our comparison tool lists no unlimited plan for Montenegro, though Saily's own page lists one (as of September 2026). That page did not name a network when we checked in September 2026. In our test Saily had the best-polished app, the smoothest install and a fast, human help desk, but the eSIM is bought only in the app and stops at the data limit. It is among the dearest providers in the places most travelers visit. Read our Saily review or visit Saily.

GigSky eSIM in our hands

Go to GigSky website View full review

GigSky suits cruise passengers and travelers who want a one-day pass, but both Montenegro reports name coastal misses. It worked well for 1 of 2 travelers who reported, which is too few to judge. One said it did not work in Bar and Kotor (23 May 2026). The other said it did not work in Budva but worked in other parts of the country, and liked not needing a separate eSIM for each country (22 May 2026).

GigSky sells no Montenegro-only plan in our comparison tool. Regional and world plans that cover Montenegro run from 200 MB to 100 GB with validity from 1 to 180 days, and its only unlimited plans are 1-day passes. We could not confirm which network it uses here. In our test a human answered the help desk at once, and the app stays partly online when the data runs out, so you can buy a new plan without Wi-Fi. Speeds felt unstable, and across all countries it is the dearest provider, though at market price in large European markets. See our GigSky review or GigSky.

Ubigi is the travel eSIM brand of Paris operator Transatel, with one reusable eSIM for 200+ destinations. Data was fast in our test, and its 3 GB, 10 GB and 30-day unlimited plans are cheap. Its weak point is support: a chatbot that ends in an email ticket, with no live agent.

Ubigi eSIM in our hands

Go to Ubigi website View full review

Ubigi suits tech-savvy travelers who want a strong network and can manage without a help desk. Its only Montenegro report is a miss: it worked for 0 of 1 travelers, too few to judge. The reviewer used Ubigi in London and across Europe with no issues "except in Montenegro where there's no service" (25 Apr 2026). The review does not say which plan or where in Montenegro.

Ubigi sells Montenegro plans of 1 GB for 7 days, 3 GB for 15 days, 10 GB for 7 or 30 days and unlimited plans for 7 or 15 days, with no throttling flagged. Its own page lists M-Tel and One Montenegro as the networks (as of September 2026). In our test the network was strong and unthrottled, but the site, app and help desk were weak: a ticket had no reply after 24 hours, the worst outcome we saw. You can top up with zero data left. Prices sit just below the market. See our Ubigi review or Ubigi.

Jetpac is a Singapore eSIM provider with plans in 129 countries. It adds extras like in-app calls, free WhatsApp and Google Maps after your data runs out, and lounge access on delayed flights. Its website, app and support are rough, so it suits travelers who can fix small issues themselves.

Jetpac eSIM in our hands

Go to Jetpac website View full review

Jetpac has no traveler reports from Montenegro yet, and our comparison tool lists no Montenegro plan for it. We also found no Montenegro page on Jetpac's own site, so we could not confirm that it covers Montenegro at all.

Elsewhere Jetpac suits frequent flyers who want extras: in-app voice packs, free WhatsApp and Maps after the data runs out on packs of 3 GB or more, and a free lounge visit if a flight is delayed by an hour or more. In our test the app was rough, and the price sat at the market, high for 3 to 20 GB. Read our Jetpac review or visit Jetpac.

Best eSIM Plans for Montenegro

Price per GB in Montenegro by eSIM Provider

How much does each provider charge per GB in Montenegro? The chart below compares plans of 1 to 10 GB that last 6 to 14 days, the usual range for a one- or two-week trip. Provider websites show only their own plans, so this side-by-side view is one you would otherwise have to calculate yourself. A shorter bar means a lower price per GB.

Fixed-size plans cover most trips, and unlimited plans differ mainly in their fair-use rules. Six providers sell a Montenegro unlimited plan in our comparison tool: Airalo (3 to 30 days), ByteSIM, eSIM4Travel, Nomad (3 to 10 days), Yesim and Ubigi (7 or 15 days). Maya sells global unlimited plans only, GigSky sells 1-day unlimited passes, and Holafly sells only unlimited plans, but its plans were not in our tool at export. Airalo slows after 3 GB a day, Nomad after 2 GB and Maya after 5 GB, and Holafly's speed was capped from the start in our test. GoMoWorld, Global YO, Roamless and Saily sell fixed-size plans only for Montenegro. Our guide to how much data you need helps you size a plan.

Best eSIM for Kotor, Budva and the Coast

No provider has 3 or more reports in any single place in Montenegro, so we name no city pick, and the overall pick, Global YO, has no city-level reports. The coast shows more misses than successes: of the 5 reports from Kotor and the 4 from Budva, only GoMoWorld's two were successes. The coast matters because 93.8% of tourist nights in 2024 were spent in the six coastal municipalities [2].

Best eSIM for Kotor

Kotor has no provider-level pick, but the pattern is clear: four of the five reports describe a miss. GoMoWorld is the only provider with a success there (1 of 1), from a traveler who said Tivat, Budva and Kotor all connected (1 Jul 2026). A Maya traveler had no signal most of the time and had to walk around to load Google Maps (10 Sep 2025), and a Maya group had no internet more than half the time across Kotor, Budva, Podgorica and Žabljak (10 Sep 2025). GigSky did not work in Bar and Kotor (23 May 2026). Yesim also had a miss in Kotor, but the reports we hold do not say what went wrong.

These misses are not a lack of 5G. Kotor sits inside the 3.6 GHz 5G footprint EKIP lists for 2024, and licence terms require 4G across the Bay of Kotor and up to 1 nautical mile offshore by the end of 2026 [1]. We found no operator-level cause, so the reports show a risk on the coast, not a rule about one network.

Best eSIM for Budva

Budva has no provider-level pick either. It has 4 reports: GoMoWorld worked (1 of 1, Jul 2026), while Yesim, Maya and GigSky each had a miss. The GigSky traveler said the eSIM did not work in Budva but worked in other parts of the country (22 May 2026). The Maya report is the three-traveler group that lost internet more than half the time. Two things stand out: the problem was working data on a visible signal, and no provider has more than one report here, so any ranking would rest on a single review.

Places with fewer reports tell a similar story. In Tivat, GoMoWorld worked (1 of 1), while a Holafly traveler had data too slow to run Google Maps even in the city (29 Jul 2026). No review describes buying or activating an eSIM at an airport, but a GoMoWorld traveler found setup easy once Wi-Fi was available after landing (27 Jul 2026), which fits its app-only purchase. In the mountains, GoMoWorld worked (Apr 2026), Global YO served a road tour through the Balkan mountains (2 Jul 2024) and Holafly worked on mountain roads (15 Jun 2026), while Maya failed near Žabljak. EKIP's 2024 report lists five municipalities without mid-band 5G (Andrijevica, Danilovgrad, Petnjica, Plužine and Šavnik) and says LTE covers about 82% of the territory [1]. No traveler has reported from those municipalities yet.

Local SIM Cards and Operator eSIMs in Montenegro

A local tourist SIM beats a travel eSIM on a stay of two weeks or more with heavy use, and a travel eSIM wins on short trips and on arriving with data already working. All three operators sell the same headline bundle, 500 GB for 15 days at €15 (as of September 2026): Crnogorski Telekom (CT) [4], One [7] and m:tel [8]. Prices include VAT, about 21% by our reading of m:tel's price list [9].

Unlimited bundles cost a little more. CT and One sell 30 days for €25, with a fair-use limit of 1.5 TB at CT [4] and a crawl after 1 TB at One [7]. The m:tel Super Turist costs €30 for 45 days, with a fair-use limit of 3 TB [8]. CT also sells a 10-day bundle with 500 minutes on its own network, 500 minutes to other local networks and 500 texts for €15, which no Montenegro plan in our comparison tool matches [4].

Montenegrin law requires every SIM to be registered with an ID or passport. At CT, Balkan and EU citizens can use a national ID, everyone else needs a passport, and the online biometric check takes up to 2 minutes [4]. CT counts data from the first traffic, call or text. Its eSIM QR code works once, so a deleted profile cannot be reinstalled, and CT refunds in full if activation fails and you contact it within 24 hours [4].

CT sells physical SIMs at its shops and at marked points with the Voli, INA and Petrol logos [4]. One delivers an online SIM order to a One store in 3 to 5 working days [7]. We could not confirm that operator desks sell SIMs at Podgorica or Tivat airport, and we found no airport prices, so a bundle bought on arrival can mean a shop visit and a passport check.

For border trips, CT sells a data-only Western Balkans eSIM with no phone number. It covers Albania, Bosnia and Herzegovina, Kosovo, North Macedonia, Serbia and Montenegro, but not Croatia: 3 GB for 3 days costs €4.90 and 15 GB for 30 days costs €16.90 [5]. The roaming allowance in m:tel's bundles covers Albania, Bosnia and Herzegovina, North Macedonia, Serbia and Kosovo, and also leaves out Croatia [9]. A travel eSIM still makes more sense for a week or less, for arriving without a passport check, and for trips that include Croatia.

Mobile Networks in Montenegro

Montenegro has exactly three mobile operators and no MVNOs [1]. m:tel had the most subscriptions at the end of 2024, about 41%, ahead of Crnogorski Telekom (CT) with about 35% and One with about 24% [1]. CT has the strongest evidence for speed and coverage, and the coastal reports show bars without working data, so the network your eSIM rides is worth checking.

EKIP, the regulator, says LTE reaches more than 98% of the population but only about 82% of the territory, and GSM about 85% [1]. It calls the terrain very demanding. 5G reached 92.5% of the population at the end of 2024 [1], and an EKIP interview with the news site Standard (1 Aug 2026) puts it at about 96% a year later. CT switched off 3G in early 2024, while One and m:tel still run it [1].

CT says EKIP's 2022 drive test found its network the fastest [6]. Ookla's Speedtest Award for the second half of 2025 also went to CT as the fastest mobile network, according to CT's press release and Telecompaper; Ookla's own speeds were not disclosed. A stock-exchange filing by Ericsson Nikola Tesla, a CT supplier, quotes an EKIP ranking from July 2025 that gave CT the largest 4G and 5G population coverage (reported). On the other side, a Montenegrin news site reports that m:tel ranked lowest in EKIP's 2019/20 test, which is old data. One has the most base stations, 472, and CT the fewest, 428 [1].

Which provider rides which network, as far as the research can show:

• Named on the provider's own page (September 2026): Holafly (MTEL, One and CT), Airalo (MTEL), ByteSIM (MTEL) and Ubigi (M-Tel and One).
• Reported only: eSIM4Travel (MTEL, from its homepage), Nomad (m:tel and "T-Mobile") and Roamless (Mtel and "T-Mobile"). Third-party sources map "T-Mobile" to CT, whose mobile business used that name before.
• Sources conflict: Yesim's page lists MTEL and Telekom, while an older Yesim blog post lists Telenor and T-Mobile.
• Not named or not confirmed: Saily (its page did not name a network when we checked in September 2026), GoMoWorld, Maya, GigSky, Global YO and Jetpac.

The providers with misses on the coast, Maya, GigSky and Yesim, are the ones whose network we could not confirm or whose sources conflict. Holafly's page lists all three networks, and its one miss was slow data in Tivat. That is a pattern in the reports, not proof that one network is at fault, and we could not confirm operator-specific dead zones. If you cross from Dubrovnik, our Croatia eSIM guide covers the other side of the border.

How to Set Up an eSIM for Montenegro

Install the eSIM at home over Wi-Fi, and switch it on after landing. Six steps cover most cases:

1. Check that your phone supports eSIM and is not locked to a carrier. Our first eSIM guide covers the check.
2. Buy before you fly. Most plans start on first connection, but Yesim's plan started at purchase in our test, and GoMoWorld's needs a manual Start in the app. GoMoWorld, Saily, Roamless and GigSky sell only in their apps, and Global YO needs its app to buy, so all of them need Wi-Fi for setup.
3. Install over Wi-Fi before the flight. Our guides cover iPhone and Samsung. One Global YO reviewer installed it at home, switched it off, then turned it on with data roaming after arriving (23 Apr 2025).
4. After landing, switch on the eSIM line and data roaming. Maya and Global YO also ask you to set the APN (the connection name) to "globaldata".
5. If bars show but nothing loads, pick the network by hand. A Maya traveler fixed a no-data problem in Bosnia this way (10 Aug 2024), and eSIM4Travel's help desk gave the same tip in our test. Our troubleshooting guide lists more fixes.
6. Watch your data. When it runs out, most apps stop working without Wi-Fi. Only GigSky, Ubigi and Roamless let you top up with no data left in our tests.

Calls and SMS in Montenegro

No Montenegro plan in our comparison tool includes minutes or texts, so calls run over WhatsApp or a similar app. Montenegro's international calling code is +382, which matters only if you buy a local SIM. Airalo's Discover+ global plans include calls and texts, but one reviewer's Global plan with calls had no coverage in Bosnia although the Europe plan listed it (22 Aug 2026), so check the country list before you buy.

Other providers add calling in other ways. Saily sells a US number as an add-on, Roamless adds in-app calls and a second number, Global YO has outgoing in-app calls and Jetpac sells voice packs. For a Montenegrin number, CT's 10-day tourist bundle includes minutes and texts (see the local SIM section above).

Free eSIM Data for Montenegro

Roamless lists a free Montenegro plan in our comparison tool: at least 300 MB, valid for 30 days after activation, with no throttling claimed. That is enough to test the install and a few map lookups, not a trip. Our tests also found small free trials at other providers, but our files do not show that they cover Montenegro, so we leave them out. More free options are in our free eSIM guide.

Summary: the best eSIM for Montenegro

Based on 81 traveler reports from Montenegro and our tests, the best eSIM for Montenegro depends on the trip. Global YO had the cleanest record, 3 of 3 travelers, and is usually among the cheapest, but the base is small, purchase is app-only and the help desk was slow. GoMoWorld has the strongest evidence, 12 of 14, and was the fastest and unthrottled in our test, but it sells no unlimited plan and needs a manual Start in its app. Holafly worked well for 9 of 10 and held up on mountain roads, but its speeds were capped in our test.

Airalo (5 of 6) is the easiest first eSIM at the market price, with the weakest record across all countries. Yesim (5 of 7) suits flexible unlimited plans, with one of the slowest help desks we tested. eSIM4Travel (2 of 2) is the cheapest in our comparison and has the best help desk, but it has no app and cannot top up without Wi-Fi. No provider reaches 20 reports, and the Kotor and Budva reports show that full bars do not guarantee working data on the coast. The best eSIM for Montenegro is one that lists Montenegro by name and is installed before you fly.
