eSIM Installed but Mobile Data Isn't Working

The Problem

Your eSIM is installed. You might even see signal bars or a carrier name at the top of your screen. But when you open a browser or try to use an app, nothing loads. No internet.

This is different from a "No Service" error. Your phone has found a network — it's just not sending data through it. The cause is almost always a settings issue, and the fixes below will walk you through each one.

Check 1: Is the eSIM Set as Your Default Data Line?

This is the most common culprit. If your phone has both a physical SIM and an eSIM installed, it might be routing all data through your physical SIM — which probably doesn't have an international plan.

On iPhone:

1. Go to Settings > Cellular
2. Tap Cellular Data
3. Select your eSIM plan as the default data line

On Android:

1. Go to Settings > Network & Internet > SIMs
2. Tap Mobile data
3. Choose your eSIM

After switching, give it 15-30 seconds to start routing data through the eSIM.

Check 2: Is Data Roaming Enabled?

Travel eSIMs connect via roaming on local partner networks. If Data Roaming is off, your phone blocks data even when it has a network connection.

On iPhone: Settings > Cellular > tap your eSIM plan > toggle Data Roaming ON.

On Android: Settings > Network & Internet > SIMs > tap your eSIM > enable Roaming.

Check 3: Turn Off WiFi

This one is sneaky. If you're connected to a weak or captive WiFi network (like an airport or hotel that requires a login page you haven't completed), your phone may think it has internet but actually doesn't. Meanwhile, it won't use mobile data because WiFi takes priority.

Turn WiFi off completely and test your mobile data on its own.

Check 4: Check APN Settings

APN (Access Point Name) settings tell your phone how to connect to a carrier's data network. Most eSIMs configure this automatically, but some require manual setup.

On iPhone:

1. Go to Settings > Cellular > tap your eSIM plan
2. Tap Cellular Data Network
3. Check the APN field — if it's blank, you may need to enter the APN from your setup email

On Android:

1. Go to Settings > Network & Internet > SIMs > tap your eSIM
2. Tap Access Point Names
3. Check if an APN is configured; add one if needed

If you didn't receive APN details in your order email, your plan likely auto-configures and this isn't the issue. Move on to the next check.

Check 5: Toggle the eSIM Off and On

Turning the eSIM line off and back on forces your phone to re-register with the network.

1. Go to your SIM/Cellular settings
2. Tap on your eSIM plan
3. Toggle it OFF
4. Wait 10 seconds
5. Toggle it ON
6. Wait for it to reconnect

Check 6: Reset Network Settings (Last Resort)

If nothing else has worked, resetting your network settings clears all network-related configurations and forces your phone to start fresh.

On iPhone: Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings

On Android: Settings > System > Reset options > Reset WiFi, mobile & Bluetooth

Be aware: This will erase your saved WiFi passwords and Bluetooth pairings. Your eSIM profiles will remain installed, but you may need to re-enable Data Roaming and re-select your default data line afterward.
