eSIM Not Working?

Toggle airplane mode off and on

Enable airplane mode for 10 seconds, then disable it. This forces your phone to re-scan for available networks and is the fix for ~40% of eSIM connectivity issues.

Check data roaming is enabled

Go to Settings → Cellular (iOS) or Settings → Network (Android). Make sure "Data Roaming" is turned on for your eSIM line. This is the most common reason eSIMs work but show no data abroad.

Set the correct eSIM line as active for data

If you have two SIMs (physical + eSIM), go to Settings → Cellular → Cellular Data and ensure your travel eSIM is selected as the data line, not your home SIM.

Check that the eSIM plan has started

Some plans only activate on first connection to a local carrier (first-use activation). Fully disable your home SIM temporarily to force the eSIM to connect.

Reset network settings

iOS: Settings → General → Transfer or Reset → Reset → Reset Network Settings. Android: Settings → General Management → Reset → Reset Network Settings. This clears stale APN configurations.

Use Smart Coach for automatic diagnosis

Open LTE.app and tap Smart Coach. It checks your APN settings, roaming state, and carrier connection automatically — even without mobile data — and walks you through the exact fix for your device and carrier.

Why is my eSIM showing "No Service"?

"No Service" usually means the plan has not started yet, data roaming is off, or the carrier in your area is not covered. Toggle airplane mode, enable data roaming, and restart your device. LTE.app Smart Coach can check your exact carrier and APN settings.

My eSIM shows as installed but has no data. What do I do?

This is almost always a data roaming toggle issue. Go to Settings → Cellular → select your eSIM line → enable Data Roaming. If that does not help, your APN settings may need updating — Smart Coach can fix this automatically.

Can I fix my eSIM without internet access?

Yes. Smart Coach works offline — it checks local device settings and APN configuration without needing a data connection. Connect to hotel or airport Wi-Fi first, then open the app.

Will reinstalling my eSIM delete my data?

Removing and reinstalling an eSIM profile may require a new QR code from your provider. Contact LTE.app support before removing the profile.
