If your eSIM is not working after VPN use, the most common reasons are stuck VPN routing, DNS conflicts, mobile data session errors, roaming handshake issues, battery optimization, or network changes that happened while the VPN was active.
This is a very common travel issue. Many travelers use VPN apps in airports, hotels, cafés, coworking spaces, or countries with restricted internet access.
Then after disconnecting the VPN, the eSIM may appear broken even though the real issue is usually software routing.
You may notice:
- bars but no internet
- apps not loading
- slow websites
- maps not working
- Wi-Fi works but mobile data does not
The good news: in most cases, the eSIM is fine. The issue is usually the VPN connection not releasing properly.
Quick answer: Disconnect the VPN fully, turn mobile data OFF/ON, turn roaming ON, disable private DNS if needed, and restart the phone.
1. VPN Tunnel Did Not Close Properly
This is the #1 reason.
Some VPN apps keep a partial tunnel active after disconnecting.
This can block normal mobile traffic.
Fix:
- Open the VPN app
- Disconnect again manually
- Force close the app
2. DNS Settings Stayed Changed
Many VPN apps change DNS servers while active.
If DNS fails, websites and apps may not load even when signal is present.
Fix:
- Disable Private DNS / custom DNS temporarily
- Use Automatic DNS
3. Mobile Data Session Became Stale
After switching between Wi-Fi, VPN, and mobile data, the data session may need refresh.
Fix:
- Turn Mobile Data OFF
- Turn Mobile Data ON again

4. Data Roaming Is OFF
The VPN may have hidden the real issue: roaming was never enabled.
Fix:
- Select the eSIM
- Turn Data Roaming ON

5. Wrong SIM Is Selected for Data
Dual SIM devices may still route traffic through another SIM.
Fix:
- Select the travel eSIM for mobile data

6. Battery Saver Suspended the VPN App
Some phones pause background VPN processes incorrectly, causing stuck routing afterward.
Fix:
- Disable Battery Saver temporarily
Helpful guide:
7. Automatic Network Selection Is Stuck
Changing networks while on VPN can confuse reconnection.
Fix:
- Toggle Airplane Mode ON/OFF
- Try manual network selection
8. VPN Kill Switch Is Still Enabled
Some VPN apps have a feature that blocks internet when VPN disconnects.
Fix:
- Disable Kill Switch in the VPN app
9. App Cache Problems
Some apps keep old VPN sessions and seem broken even when internet works.
Fix:
- Force close the affected apps
- Reopen them
10. Device Needs Full Restart
A reboot often restores routing instantly.
Fix:
- Restart the phone
