If your eSIM stopped working after resetting network settings, the cause is usually erased mobile settings, disabled roaming, lost APN values, wrong SIM priorities, or temporary software refresh issues — not that the eSIM itself was destroyed.
Resetting network settings is a common troubleshooting step on iPhone and Android. It can solve Wi-Fi, Bluetooth, and mobile data issues, but it also resets many important cellular preferences.
That means your eSIM profile may still be installed, but your setup changed.
You may notice:
- eSIM installed but no internet
- No Service after reset
- travel eSIM disappeared from data line
- main SIM became default again
- roaming turned OFF
- APN missing after reset
This guide explains exactly why your eSIM is not working after resetting network settings, how to fix it fast, and how to avoid repeating the issue.
Quick answer: Your eSIM is usually still installed. Re-enable the line, turn Data Roaming ON, select the eSIM for mobile data, check APN settings, and restart the phone.
1. Resetting network settings changed preferences
This is the #1 cause.
Network resets often erase saved settings such as:
- preferred data SIM
- Wi-Fi networks
- Bluetooth pairings
- roaming preferences
- manual carrier selections
Your eSIM may still be installed but no longer selected.
2. The main SIM became default again
On dual SIM phones, resets often return the physical SIM as default for:
- mobile data
- calls
- messages
This makes users think the eSIM stopped working.
Fix:
- Open Cellular / SIM settings
- Select the eSIM for mobile data

3. Data Roaming was turned OFF
Many travel eSIM plans need roaming enabled to use partner networks.
After reset, roaming may return to OFF.
Fix:
- Select the eSIM
- Turn Data Roaming ON

4. APN settings were cleared
Some eSIM providers require custom APN values for data access.
If those values were removed, you may have signal but no internet.
Fix:
- Check provider instructions
- Re-enter APN manually

5. Manual network selection was lost
If you previously selected a stable carrier manually, the reset may return to automatic network search.
This can cause weaker performance or endless searching.
Fix:
- Try manual network selection again
6. The eSIM line is disabled
Sometimes the line remains installed but turned OFF after reset.
Fix:
- Open SIM Manager
- Enable the eSIM line

7. Temporary modem refresh issue
After reset, the modem may need a clean restart.
Fix:
- Restart the phone
- Wait 2–5 minutes
8. The eSIM was not deleted
Important: Resetting network settings usually does not delete the eSIM profile itself.
It mostly resets preferences and network data.
If the profile was manually removed separately, that is different.
