Why have an eSIM with multiple networks + How to switch operators (iPhone/Android 2025)

Many eSIM providers offer packages that connect to multiple mobile networks. This gives you flexibility: you can either use the default automatic network selection or manually switch between networks if you experience connection issues. 

Choosing providers with multiple networks – especially major ones – can make a significant difference, particularly in remote areas like mountains. If one network has a weak signal, you can manually switch to another network supported by your eSIM plan.

How to Manually Select Networks on Android/Samsung

Switching networks on your Android device is simple:

  1. Go to Settings
  2. Select Connections
  3. Choose Mobile Networks
  4. Scroll down and select Network Operators
  5. Choose your preferred network from the list

(Your phone will display all available networks. Try the networks included in your eSIM package.)

How to Manually Select Networks on iPhone

For iPhone users, the process is equally straightforward:

  1. Go to Settings
  2. Select Cellular
  3. Choose Network Selection (one of the first options)
  4. Turn off automatic selection to view available networks
  5. Select your preferred network

(Your phone will display all available networks. Try the networks included in your eSIM package.)

How Multi-Network eSIM Plans Work

When you purchase a data eSIM with multi-network support, you gain access to several carriers in your destination country. Your phone will automatically connect to the strongest available network (this is called automatic network selection).

But here's the key advantage: you can take control and manually switch networks whenever needed. This feature becomes invaluable when:

  • Automatic selection chooses a weaker network
  • You're in areas with unstable coverage
  • One carrier has technical issues
  • You need better speed for specific tasks

Real-World Example: Tunisia

According to our Guide to eSIM Data Plans in Tunisia, the most reliable networks are Tunisia Telecom and Orange. For the best possible connection, choose an eSIM provider that supports both networks.

In this case, eSIM4Travel and Yesim offer packages with access to these two main networks. 

Why Multiple Networks Matter for Travelers

Remote Area Coverage

Mountain areas, islands, and rural regions often have unstable coverage. Different operators place transmitters in different locations. Where one network fails, another might provide perfect signal.

Choosing the Right Multi-Network Provider

What to Look For

When comparing travel eSIM options, check:

  • Which specific carriers are included
  • Whether the major national operators are covered

Best Multi-Network Providers

Most well-known eSIM providers utilize multiple networks within a single package. However, it's important to check whether the provider offers multiple networks for your main destination and which ones. From our experience, these providers have good local networks:

It's also worth noting that for some countries (especially smaller ones), no eSIM provider supports multiple networks due to limited local offerings.

Summary

When comparing eSIM providers, prioritize those offering multiple network options, especially if these networks are major carriers in your destination country. The ability to manually switch networks gives you control over your connectivity.

Whether you're planning trips to Japan, Egypt, or Iceland, eSIM plans with multiple networks provide the flexibility that modern travelers need.

Don't let poor connectivity disrupt your travels. Choose the best eSIM provider with multi-network support and stay connected wherever your journey takes you.
