2. Switch on/ off Airplane Mode

If your Holafly eSIM isn’t working, a quick toggle of Airplane Mode might just do the trick! This simple step disconnects your device from all networks, helping to clear up any minor software glitches that could be affecting your connectivity. Follow these steps:


  • Enable Airplane Mode for 30 seconds > then turn it off > After that, check that your Holafly eSIM and data roaming are active > test your connection.

3. Manually Select a Network Operator

Sometimes your device doesn't automatically connect to the best available network, which can cause your eSIM to stop working. If that happens, try manually selecting a network and see if it helps!
