Ubigi eSIM Review 2026: Speed, Prices, Coverage and Support Tested

Ubigi purchase process

Purchase process

Vefru rating

Fast guest checkout and an email QR code within a minute. A clunky website, no social login and confusing form steps cost most points.

4/10

Verdict: Buying works and the QR code arrives within a minute, but the website is the weakest we have seen from a big eSIM provider.

You buy on Ubigi's travel store as a guest. There is no account and no password at this stage. The eSIM comes by email as a QR code, with a manual activation code as a backup. Each order can hold only one data plan [2].

Prices show in one of seven currencies: EUR, USD, AUD, GBP, CAD, CNY and JPY [2]. Ubigi says the currency follows your registered country of residence. In our test the website charged US$6.00, while the app's payment sheet later showed a €6.00 price.

How to buy a Ubigi eSIM in five steps

1. Pick a destination and a plan. The plan page shows the data amount, the validity and a 5G label. It also shows Ubigi's own price comparison with two rivals. The terms say this data comes from partners Ubigi may have commercial ties with, refreshed about once a week [8].
2. Enter your details. First name, last name, email twice and country of residence. There is no Google, Apple or Facebook login anywhere on Ubigi.
3. Confirm your phone. Press the "I CHECK" button, then flip the "My device is compatible" switch. Ubigi's own test is to dial *#06# and look for an EID number; the phone must also be carrier-unlocked [2] [7].
4. Pay. The checkout showed Google Pay and credit or debit cards. Ubigi's payment list also names Apple Pay, Visa, Mastercard, American Express, Diners Club, Discover and UnionPay [4]. PayPal and JCB work only inside the app, and PayPal cannot pay for your first eSIM at all [5].
5. Wait for the email. The thank-you page promises the QR code within 15 minutes. Ours arrived within a minute.

What the Ubigi order email contains

Sending the eSIM by email is the right call. Airalo does it too, while Roamless and others force you into their app. The email holds three things: a "hold and press" QR code for same-phone installs, a manual activation code and an app "Sign up" button.

One detail shows the lack of design care. The QR code sits in the body of the email, not in an attached PDF or PNG like most providers send. That makes it harder to download and work with.

Where the Ubigi website falls short

• One plan size per page. The plan page does not show other data amounts for the same country, so Ubigi cannot easily sell you a bigger plan. Press back and you are out of the country list and start over.
• Odd form controls. A button plus a switch to confirm compatibility, and a terms checkbox below the payment section.
• Clutter. A floating Trustpilot badge and a chat button cover text and even the payment logos.
• Looks like a startup. The visuals and the flow made us doubt this was one of the biggest eSIM providers on the market.

The positive surprise was Google Pay at checkout. If you want a smoother purchase, our tested ranking of eSIM providers shows who does it better.

Ubigi mobile app

Mobile app

Vefru rating

Feels like a wrapped website: confusing sign-up, support buried last in the menu, top-up and orders ignoring your eSIM. Settings is the one good page.

3/10

Verdict: The app feels like a wrapped website, confuses you at sign-up and buries support at the end of the menu. You can skip it and still use your eSIM.

Ubigi has apps for iOS and Android plus a web portal at ubigi.me, all behind one username and password [6]. On Google Play the app has 3.7 stars from 7,310 ratings and over 1 million downloads. The App Store rating is 4.6 from 10k ratings. The website works in 18 languages, including Polish but not Czech [2].

Ubigi app sign-up: log in or sign up after a web purchase?

We had bought with our email, so we tried "Log in" and asked for a password reset. No email came, not even in spam. Our guess: a web purchase creates no account, so there was nothing to reset. "Sign up" was the right choice, and it worked after a confirmation email.

The form is long: first name, last name, email, password twice, country of residence and two consent boxes. Two onboarding screens follow. The first asks which device you use: smartphone, tablet, laptop, mobile hotspot or connected car. The second asks what you want to do: buy a new eSIM, scan a Ubigi QR code or detect one.

We scanned the emailed QR code from a laptop screen. The camera would not focus on the first try, but the second attempt worked.

What works and what does not in the Ubigi app

• Dashboard. Shows your plan, data used, the exact expiry date and time, and a "0 UbiCoins" loyalty badge. Clear enough.
• Plan details take a detour. Tapping the plan does nothing. You open a three-dot menu and pick "details".
• Top up ignores your eSIM. It opens the full country store instead of the plan you own.
• Orders shows nothing. Our web purchase, scanned into this very app, was not listed.
• Menu. Dashboard, Top up, Orders, Payment cards, Loyalty, Rewards, Settings and Contact us. The difference between Loyalty and Rewards is anyone's guess.
• Settings is the best page. Biometric login, password change, copy your ICCID, privacy preferences and account deletion, all easy to find.
• Assistance goes to cars. The help link opens a page that first asks whether you drive a BMW or a Land Rover. Ubigi also sells connectivity for cars from Jaguar, Land Rover, BMW and others [2]. That explains the page, but not why a phone user lands on it.
• Design. Dark theme with a teal accent. But also a white empty block in the menu, a white square dialog, a clipped banner and US date formats.

The in-app store itself is fine: a search box, Local, Regional and Global tabs, and twelve popular destinations with flags. But the app sits far behind Airalo and Saily. eSIM4Travel has no app at all, just a website good enough that you rarely miss one. That may be the better model for Ubigi.

Ubigi eSIM installation

eSIM installation

Vefru rating

One tap in the app or the emailed QR code, and data worked at once. Six emails and a confusing success screen cost points.

8/10

Verdict: One tap in the app or a hold-and-press on the emailed QR code installs the eSIM; data worked right away with roaming on.

Ubigi gives you several ways in. iPhone and Android take a QR code or the app, and iPad adds iPadOS Settings. Windows 11 uses a QR code or the Mobile Plans app, and Windows 10 also works [7]. The eSIM is meant to stay on your phone. Ubigi says you keep it for future trips, and later top-ups need no new QR code [2].

How to install a Ubigi eSIM from the Android app

1. Tap "Install your eSIM" on the orange banner at the top of the dashboard. We did this at 13:12.
2. Read the warning. The dialog says a plan covering your current location activates immediately. Tap Continue.
3. Allow the system prompt "Allow Ubigi to use your phone's eSIM?". No QR code and no code typing is needed on this path.
4. Wait through a long loading. A success screen then announces the eSIM is installed for "global connectivity". We found it confusing, but it is the confirmation. Go to the dashboard.
5. Turn on mobile data and data roaming for the Ubigi line in your phone settings. This is the step that matters most. The profile showed up as "eSIM 3", provider Ubigi.
6. Check the dashboard. At 13:19 the plan was active with 0 MB used of 3 GB and an expiry exactly 15 days later, to the minute.

Data started right away and was fast, with 5G showing. No phone restart or other tricks. If you prefer, skip the app entirely: install from the email and it works the same.

Ubigi eSIM installation on iPhone and other devices

Hold and press the QR code in the email on the phone itself, scan it from another screen, or type the manual activation code. Install at home: the plan only starts when the eSIM first connects in a covered destination. An unscanned website QR code stays valid for 6 months [8].

iPhone users can follow our page on adding an eSIM on iPhone; Samsung owners have their own version. If scanning fails, you can turn the activation code into a QR code.

What confused us during Ubigi installation

• Six emails for one eSIM. The QR code, payment details, "time to connect", email verification, "ready for global connectivity" and "plan active". Two would do.
• No data-line prompt. The app never asked which SIM should carry data, the usual final step. You set it yourself in phone settings.
• Waiting before installing. A "Final step: waiting for Ubigi connectivity" screen appeared in onboarding before the eSIM was installed. Its instructions could not be followed yet.

Ubigi customer support

Customer support

Vefru rating

A well-made chatbot checklist, then an email ticket. No human in the chat, and our ticket had no reply after 24 hours.

2/10

Verdict: The chatbot's picture checklist is well made, but no human joins the chat, and our email ticket had no answer after 24 hours.

Ubigi's support runs through its website: a help center sorted by device brand, a long contact form and an AI chat agent called "Ubi". The Privacy Policy mentions chat, email and telephone, but we found no support phone number on any page [9]. The only email listed, [email protected], is for data-protection questions [8].

Finding support is a task in itself. In the app, "Contact us" is the last of eight menu items. "Need assistance" is small text at the bottom of an onboarding screen. On the thank-you page the only support link sits inside a footnote.

Our Ubigi support test, minute by minute

1. 13:27, Contact us. The app opened the car-or-device web page described in the app section. We picked Android, the second time we had told Ubigi our device.
2. A wall of FAQs. Much of it was irrelevant: iPhone threading, Windows 10 and 11, a missing pictogram in Japan. The contact form at the bottom wants a 19-digit SIM number, device, request type, message and an attachment.
3. The chat instead. The floating green button opens "Ubi". It asked where we were, whether we had a valid plan and which device we used, the third time for that question. It did not know we had already used data.
4. A good checklist. The bot walked through airplane mode, data roaming and the APN setting "mobiledata" with annotated screenshots. We usually dislike these bot tutorials; this one is well made.
5. 13:31, still "not connected". The bot asked for our email and, for the fourth time, our device. The device field first threw a validation error.
6. 13:32, ticket created. "Your conversation has ended." No human, no stated response time.
7. One hour later, nothing. 24 hours later, still no email. That is a failed test.

Other providers do this far better. eSIM4Travel and Roamless hand you to a real person inside the chat within minutes. If support matters to you, see our test of the best eSIM customer support.

Ubigi eSIM not working? Try this first

Ubigi's own checklist, from the app and the chatbot, fixes most problems before you ever need a ticket:

• Data roaming on for the Ubigi line, the step that got our connection working.
• Ubigi as the data line in your phone's SIM settings, with Wi-Fi off while you test.
• VPN off. The app says a VPN can block the pairing.
• APN set to "mobiledata". It is normally set automatically; check under Access Point Names.
• Airplane mode off and on to force a fresh network search.

If none of that helps, our eSIM troubleshooting page covers the next steps for any provider.

Ubigi speed test

Speed test

Vefru rating

Full 5G speed with no sign of throttling, a timely low-data warning, and a top-up possible with zero balance. Only the vanishing plan card jarred.

9/10

Verdict: 568 Mbps down, 88 Mbps up on 5G, no throttling, plus the only timely low-data warning a provider has ever sent us.

The Vefru speed test runs from our base, not in the destination. It measures what Ubigi's network lets through, not a country's coverage. Our eSIM connected to O2 Czech Republic on 5G, with the roaming icon on. Ubigi promises speeds up to 5G on 4G and 5G networks [2].

What happened when our Ubigi data ran out

1. 16:40 and 16:43. Two speed runs at what looks like the full physical capacity of the network at our location, so no throttling.
2. 16:44. Push notification: "Heads up! Your CZECH REPUBLIC data plan is almost out with less than 95 MB left. Top up now!" A margin of about 100 MB is enough to act on.
3. 16:47. We opened the store and reached the payment sheet with Google Pay, Link, card and PayPal. Buying more data with an empty balance works.
4. 16:50. The phone's counter read 3.23 GB on the Ubigi line, a small overrun within the usual range.

After the data ran out, the plan card simply disappeared from the dashboard. There was no top-up button for the same plan, only "Get a new data plan". Still, reaching the checkout with the data gone matches what Ubigi calls "Zero Rating": the app stays reachable with an empty balance [2]. Only GigSky has managed the same in our tests.

Ubigi unlimited plans and the fair-use limit

Ubigi's English help center says 7-day country plans drop to 1 Mbps after about 15 to 25 GB, depending on the country. 30-day regional plans slow after 60 GB. Its blog and product pages say 2 Mbps instead, and the terms give no number at all [8]. Customers report the slowdown at around 25 to 30 GB.

A 3 GB plan can vanish in an afternoon of heavy use, as our speed tests showed. Work out your real need with our travel data calculator. Our 4G vs 5G explainer tells you whether 5G matters for your trip.

Ubigi eSIM prices and plan sizes

Prices

Vefru rating

Cheap for 3 GB, 10 GB and unlimited plans. No 5 GB or 20 GB size, and dear Gulf prices, cost points.

8/10

Verdict: Fair to cheap, best for 3 GB, 10 GB and 30-day unlimited; with no 5 GB or 20 GB size you often buy up.

As of 2 Oct 2026 we compared 1,018 Ubigi plans (738 fixed, 280 unlimited) with 13 other providers. Each comparison matches the same country, data amount and trip length. The median Ubigi plan costs $21.00. The median single-country fixed plan costs $14.00, or $2.30 per GB.

Ubigi plan sizes and typical prices

Ubigi sells 1 GB, 3 GB, 10 GB, 25 GB and 50 GB plans, plus a few 0.5 GB day plans and 100 to 200 GB plans. Median prices across its single-country plans:

The ladder rewards going big:

• 1 GB to 3 GB: the price doubles (+$6.00), and so does the validity.
• 3 GB to 10 GB: the price doubles again (+$9.00) for 3.3 times the data, $1.29 per extra GB.
• 10 GB to 25 GB: 1.9 times the price (+$15.75) at the same validity.
• 25 GB to 50 GB: 1.7 times the price (+$16.00), $0.64 per extra GB.
• 7 days to 30 days on 10 GB: only 16% more.

The catch is the missing rungs. A 5 GB need means buying 10 GB, and a 20 GB need means 25 GB. Our pages on what 5 GB covers and what 10 GB covers help you decide whether the bigger plan is wasted money.

Ubigi unlimited plan prices

Ubigi sells 253 single-country unlimited plans in 104 countries for 7, 15 or 30 days, at median prices of $25.00, $40.00 and $55.00. The 30-day figure is the lowest among providers with more than a handful of such plans. Only Maya Mobile's single global plan, at $49.99 for 30 days, costs less. The longer the plan, the better the deal against rivals. Best value in Italy, Lithuania, Norway and Denmark; worst in the UAE and the US.

A 30-day unlimited plan costs about 1.5 times the 50 GB plan and pays off above roughly 59 GB, before the fair-use slowdown from the speed section kicks in.

Ubigi World plans: Best World vs World

Two global plans exist. Best World covers 178 destinations and World covers 201, including Iran, which Best World lacks [2]. One-off prices in USD, as of 28 Sep 2026 [2]:

The 12-month World plans run 360 days. World also comes as a subscription [2]:

• Monthly World: 5 GB for $17.00, 20 GB for $44.00 or unlimited for $120.00 per month. You can cancel after 3 months.
• Annual World: 60 GB (5 GB a month) for $180.00 or 240 GB (20 GB a month) for $360.00, paid upfront with no extra monthly charge.

In our comparison the global plan is a good deal, the Europe plan is average and the Asia plan is dear. Discounts exist too. Ubigi's site mentions a WELCOME10 promo code, 10% off for newsletter sign-up and student discounts through Student Beans. The UbiClub loyalty program collects UbiCoins per purchase, and there is a refer-a-friend scheme.

How Ubigi compares on 10 GB, 30-day plans

All providers ranked by median price per GB for 10 GB, 30-day plans, the same basket in every Vefru provider review. It is also the size where Ubigi's volume discount shows best.

Where Ubigi is cheap and where it is not

The box below sums up Ubigi's price position against the market: its rank among fixed-data providers, how often it had the cheapest or dearest plan, and the countries at each end. "Cheaper" means more than 5% below the median for the same country, data amount and trip length; "pricier" means more than 5% above.

Two patterns stand out. Ubigi is cheapest most often in Africa, French Polynesia, Venezuela and Guyana, and it is the third cheapest provider in France and India. It is dear across the Gulf and Central Asia, and in Japan and the UAE it is one of the two most expensive providers.

Ubigi customer feedback

Customer feedback

Vefru rating

Customers praise easy setup, auto-activation on landing and fair prices. Complaints center on eSIMs that never connect, slow data and support with no live agent.

8.2/10

Verdict: Customers praise easy setup, auto-activation on landing and fair prices; they complain about eSIMs that never connect, slow data and no live support agent.

Ubigi has 4.1 stars on Trustpilot from 47,238 reviews, 4.6 on the App Store and 3.7 on Google Play. Its own homepage advertises 4.6 out of 5 with "60K reviews". The Trustpilot widget on the same site counts about 46,955 reviews, so the two figures do not match [2].

Both sides match our own test: data worked at once and the price was low, but our support ticket went unanswered. Japan is the country customers praise most, which the traveler reports in the next section confirm. The box below pulls out the themes that keep coming up, plus four typical reviews in the customers' own words.

What customers like and dislike

Often praised

Buying, installing and activating the eSIM is quick and easy, even for first-time eSIM users

The eSIM switches on automatically after landing and coverage is reliable, especially in Japan

Prices are fair and much lower than roaming with a home carrier

The app shows data usage clearly and makes topping up simple

Often criticized

For some travelers the eSIM never connects or suddenly stops working mid-trip

Data can be slow or unstable, often stuck on LTE or 3G despite full 5G bars

Support is mostly AI and email with no live agent, and refunds can be hard to get

"Unlimited" plans are slowed down after a fair-usage limit, often around 25 to 30 GB

Typical reviews

Coverage

Absolutely faultless! We have travelled all over Japan and have had wonderful coverage. The connectivity has been seamless. Having read the reviews we turned it on as we left Heathrow and it was all ready to go as we landed. A very reasonable price for the Internet facilities we needed. Well definitely use again.

Activation

Getting Ubigi eSIM was the best choice I have made for my vacation in Spain. Installing and activating the card was easy and fast. Once we landed in Spain the card was activated and our data started streaming. The price was also great $12 for 10 GB for 30 days! I would highly recommend getting Ubigi eSIM for your next vacation abroad.

Price

This eSIM is perfect for international travel. It skips the airport kiosk lines and provides data straight away upon landing. The coverage is excellent and much cheaper than my usual carrier’s roaming fees. The app is easy to use for tracking data usage and topping up. Highly recommended for anyone going for Vacations abroad. Thanks you Ubigi.

Connection

Bought a ubigi esim based on a recommendation and it didn’t work. Followed all instructions and troubleshooted with the support team and couldn’t get it working. Wasted two days of my trip trying and had to make other arrangements.

Ubigi coverage

Coverage

Vefru rating

Reliable in Japan, Western and Southern Europe, Morocco, Canada and Türkiye. China, Macao, Mexico, Costa Rica and much of sub-Saharan Africa are weak.

9/10

Verdict: One eSIM for 200+ destinations, reliable in Japan, Western and Southern Europe, Morocco and Canada; weakest in China, Macao, Mexico and Costa Rica.

Ubigi claims 200+ destinations on five continents, with new countries added every month [3]. It credits this to Transatel's own mobile network code, MNC 901-37, and agreements with more than 200 operators [1]. Each World plan names its partner network per country: T-Mobile in the US, EE and Three in the UK, KDDI and NTT Docomo in Japan [2]. Cuba, Lebanon, Libya, Syria, Yemen, Myanmar, the Maldives, Zimbabwe and North Korea were not in the destination list.

Two extras are worth knowing. Any plan can be a hotspot, and you can switch between a home-country IP address and a local one [2]. Our page on eSIMs with several networks explains how to switch operator when one network is weak.

Traveler reports tell the rest: we have 2,792 country-level reports for Ubigi as of 28 Sep 2026, and 85.1% say it worked. Japan alone gives 1,210 of them, with 1,092 (90%) working, on par with the market there. Outside Japan the raw rate is 81.1%. Almost all of the gap to the market comes from China and Macao; everywhere else Ubigi is an average performer.

Where Ubigi works and where to pick another eSIM

• Reliable: Japan 90%, Morocco 98%, Italy 96%, Spain 95%, Canada 95%, the UK 92%, France 92% and Türkiye 92%. Pan-European trips score 95%, and in London Ubigi beats most rivals. In Japan, rural trails hit 97% and airports 83%, but Shibuya, big stations and Tokyo Disney Resort are weaker. Our Japan eSIM guide ranks providers for that trip.
• Fine with a caveat: South Korea 88%, the US 87%, Singapore 86%, Thailand 86% and Germany 83%. In the US, New York, Chicago and Orlando are weaker than the country average. Bali scores 50% on area reports even though Indonesia as a whole is at 90%.
• Pick another provider: China 49% (35 of 72 reports, last of 12 providers, Beijing 0 of 9) and Macao 0 of 6. Ubigi's partner in China is China Telecom [2]. Also weak: Mexico 56%, Costa Rica 29%, South Africa 55%, Iceland 72%, Sweden 64%, Finland 40%, Israel 0 of 3 and the UAE 1 of 3. Maya Mobile, Roamless and Nomad are the strongest alternatives in those markets; for Mexico see our Mexico eSIM guide.

Sub-Saharan Africa is weak for Ubigi at 40% of reports, but the whole market is weak there, so no provider is a safe bet. Saudi Arabia, Qatar, Jordan and Oman have no Ubigi reports at all, so treat the Gulf as unknown. The box below shows the full country-by-country picture from our database. Read it before you buy for a country not named above.

Ubigi terms and conditions

Verdict: Strict on refunds and free to cut you off at any time, but EU data rules cover every customer and disputes go to French courts.

Ubigi is a trademark, not a company; Transatel SAS is the contracting party and data controller [9]. The terms date from Sep 2024 and give no street address [8]. The only postal address, in Courbevoie near Paris, is in the Privacy Policy [9]. Beyond the clauses in the box below, a few points matter in practice:

• Refund mechanics. Request a refund through the online form with proof of payment within 14 business days of the purchase or the fault. Approved refunds arrive within 10 business days, and plans cannot be moved to another account [8].
• Data only, no emergency calls. The terms rule out a phone number, voice calls including numbers like 911, and SMS. Keep your home SIM active for those [8].
• Inactivity. An eSIM unused for 24 months can be suspended, with 3 months to restart it. Liability is capped at one month of your actual charges [8].
• Your data. Transatel may collect a copy of your ID, your IMEI and EID and country-level location. Traffic data is kept 10 years, customer data 5 years after the contract ends. Some processors sit in the US under EU safeguards. Complaints go to the French regulator CNIL [9].
• Cookies. Two ad trackers set a "necessary" cookie that lasts a year and needs no consent [10].

Ubigi review summary

Verdict: A strong network and fair prices wrapped in a weak website, a confusing app and support that never wrote back. Vefru test score 6.4 out of 10.

Ubigi suits people who know their way around phone settings: buy on the website, install from the email, switch on data roaming. You get fast 5G data, a useful low-data warning and the chance to buy more with an empty balance. Prices are fair for 3 GB and 10 GB and good for long unlimited plans. Traveler reports are strong across Japan and most of Western Europe.

What drags the score down is everything around the eSIM: a startup-grade website, an app far behind Airalo and Saily, and a support ticket nobody answered. If something goes wrong on your trip, you are on your own.

Buy Ubigi if

• You are comfortable with technology and just want an eSIM with decent coverage and prices.
• You are going to Japan, Italy, Spain, France, the UK, Morocco, Canada or Türkiye, or touring several European countries on one plan.
• You need 3 GB, 10 GB or a 30-day unlimited plan, the sizes where Ubigi is cheapest.
• You want one eSIM you keep for future trips, with top-ups that need no new QR code.

Look elsewhere if

• This is your first eSIM or you want a polished app and support you can reach. Airalo is the friendlier start according to our tester, even though its traveler reports are weaker.
• You are heading to China, Macao, Mexico, Costa Rica or South Africa, where Ubigi fails more than its rivals. Maya Mobile or Nomad score better there.
• You need exactly 5 GB or 20 GB, because Ubigi sells neither and you would pay for the next size up.
• You may need a refund. Once you scan the QR code, the money is gone unless Ubigi's side is at fault.
