eSIM Shows "No Service"

Enable data roaming

Settings → Cellular → Cellular Data Options → Data Roaming: On (iOS). Settings → Connections → Mobile Networks → Data Roaming: On (Android). Most "No Service" issues are caused by data roaming being disabled.

Set the eSIM as the active data line

If your phone has a physical SIM alongside your eSIM, check which line is set for data. iOS: Settings → Cellular → Cellular Data → select your travel eSIM. Android: Settings → Connections → SIM Manager → Mobile Data → select eSIM.

Toggle airplane mode

Airplane mode for 30 seconds, then off. Wait 60 seconds. Your phone will search for local carriers and register. This fixes most "No Service" situations.

Manually select a carrier

iOS: Settings → Cellular → Network Selection → disable Automatic → select a carrier from the list. Android: Settings → Connections → Mobile Networks → Network operators. Choose any carrier shown.

Restart your device

A full restart forces your phone to re-read the eSIM profile and search for carriers fresh. If no service after restart, proceed to Smart Coach.

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.

My eSIM shows "No Service" even after all steps. What next?

Contact LTE.app support — the issue may be with the specific plan or the carrier in your location. In some countries, specific carriers provide better coverage. Smart Coach can detect the issue and suggest the correct carrier.
