If your eSIM shows No SIM after installation, the most common reasons are incomplete activation, disabled eSIM line, software refresh issues, wrong SIM priority settings, delayed network registration, or device compatibility problems.
This can be frustrating. You installed the eSIM successfully, but instead of signal, the phone shows No SIM, No Service, or behaves as if nothing was added.
The good news: in many cases, the eSIM profile is installed correctly and only needs activation or settings adjustments.
You may notice:
- No SIM after QR installation
- eSIM visible but inactive
- No Service after setup
- main SIM works, travel eSIM does not
- phone asks to add plan again
This guide explains exactly why your eSIM shows No SIM after installation, how to fix it quickly, and how to complete setup properly.
Quick answer: Restart the phone, enable the eSIM line, set it as your data SIM, turn roaming ON, and wait a few minutes for network registration.
1. The eSIM Installed but Was Not Activated
This is the #1 reason.
Some phones download the profile but leave it OFF until you enable it manually.
Fix:

- Turn the eSIM line ON
2. Phone Needs a Restart After Installation
The system may need a reboot to load the new profile correctly.
Fix:
- Restart the phone fully
3. Network Registration Takes Time
Some plans need a few minutes to register on the local network.
Fix:
- Wait 5–10 minutes
- Keep the phone unlocked and connected
4. Wrong SIM Selected for Mobile Data
Your physical SIM may still be active for data while the eSIM appears unused.
Fix:
- Select travel eSIM as mobile data line
