If you've been using your eSIM but suddenly your data has stopped workingSometimes the SIM can stop working. When this happens:

Turn on Airplane Mode for 1 minute

Turn off Airplane Mode - this should reboot the connection!

If your phone says it's connected to LTE or 4G but the data isn't working, try to manually turn off LTE/4G to connect to 4G/3G.

iPhoneSettings > Mobile > Mobile data options > Disable LTE > Restart
AndroidSettings > Connections > Mobile Networks > Network Mode > Switch to 3G/2G > Restart

It might look different depending on your device! If these instructions don't match exactly, explore your settings until you find Network Mode
