If your eSIM is installed but not working, do not worry — this is one of the most common travel eSIM issues, and in most cases it is easy to fix.
Many travelers complete installation successfully, see the eSIM profile inside their phone settings, and expect everything to work immediately. Then they notice:
- no signal
- no mobile data
- connected but no internet
- cannot find a network
- slow or unstable connection
Usually, the eSIM itself is installed correctly. The issue is often related to settings, activation timing, roaming configuration, or network registration.
This guide explains exactly why an eSIM can be installed but not working, and how to fix it step by step.
Quick answer: If your eSIM is installed but not working, check whether it is enabled, selected for mobile data, activated, and allowed to roam. Restarting the phone often solves the problem too.
What does “installed but not working” actually mean?
Installing an eSIM profile and using the plan successfully are not always the same moment.
Your phone may show the eSIM in settings, but one of these steps may still be missing:
- the plan has not activated yet
- the eSIM line is disabled
- the wrong SIM is selected for data
- data roaming is turned off
- network registration has not completed
- you are outside the supported country

Top reasons your eSIM is installed but not working
1. The eSIM has not activated yet
Some travel eSIM plans activate only when:
- you arrive in the destination country
- the phone connects to a supported network
- mobile data is first used
If you installed it before departure, this may be normal.

2. The eSIM line is turned off
Many phones allow installation but keep the line disabled until manually enabled.
3. Wrong SIM selected for mobile data
On dual SIM phones, your regular SIM may still be selected for internet instead of the travel eSIM.
This can also create roaming charges.
