"No Service" after landing
It usually means the phone has not found a network it is allowed to use yet. On landing that is normal for a few minutes.
Give it a moment first
- Wait 2-3 minutes after you turn airplane mode off. Finding and registering on a foreign network is not instant
- Then airplane mode on for 10 seconds, and off again
If it is still saying it
- Make sure your plan covers the country you are actually in
- Pick a network manually instead of letting the phone choose
- Check the Atli eSIM is switched on and set as your data line
Do not delete the eSIM at this point. Reinstalling does not make a network appear, and you need data or wifi to install again.
