What is the fastest solution if my eSIM is not working?

1. Confirm eSIM is set as the default data card

Go to your device's SIM management page (iOS path: Settings → Cellular; Android path: Settings → Mobile Network / SIM Manager), select the target eSIM and set it as the default mobile data card to ensure data traffic goes through the eSIM channel.

2. Enable data roaming for the eSIM

Most international travel eSIMs require roaming functionality to work at your destination. Find the data roaming option in the eSIM settings page and enable it.

Note: Simultaneously turn off roaming for your primary SIM card to avoid incurring additional charges.

3. Manually switch to the carrier specified in your plan

Go to your device's "Carrier" settings page (turn off "Automatic Selection"), manually select the local carrier specified in your eSIM plan description to avoid the device automatically connecting to an incompatible network that prevents usage.

4. Restart your phone

If the above steps don't work, simply restart your phone to let the system rescan and reconnect to the mobile network associated with the eSIM. Most temporary network issues can be resolved through a restart.
