My eSIM has no mobile data or is not connecting

Use this guide when your eSIM has already been installed on your device but is not connecting to a mobile network.

Step 1 — Confirm the eSIM is set as your active data line

iPhone: Settings → Mobile Service → Mobile Data → select your eSIM plan

Android/Samsung: Settings → Network & internet (or Connections → SIM card manager) → select your eSIM for mobile data

Step 2 — Make sure the eSIM line is turned on

iPhone: Settings → Mobile Service → tap your eSIM plan → confirm Turn On This Line is enabled

Android/Samsung: Settings → SIMs → confirm eSIM is toggled on

Step 3 — Check your data allowance hasn't run out

Check your data balance in the app. If you've used your full allowance, data stops until you top up or your plan renews.

Step 4 — Toggle airplane mode on and off

Turn Airplane Mode on, wait 10 seconds, then turn it off. This forces your device to reconnect to the network.

Step 5 — Restart your device

Step 6 — Check coverage in your area

Check the coverage map in the app. If you are travelling, confirm your plan includes roaming in the country you are in. See ****Does my plan include roaming?

Step 7 — Check APN settings (Android only)

Settings → Network & internet → Mobile network → Access Point Names. If the active APN fields are blank, delete the APN entry and restart — your device should repopulate the correct values automatically. iPhone manages APN settings automatically.
