If your eSIM is not working after resetting network settings, the most common reasons are roaming turned OFF, mobile data line changed, APN settings cleared, Wi-Fi and carrier preferences reset, or the phone needing to re-register on the network.
This is a very common issue for travelers. Many users reset network settings to fix one problem, then discover their eSIM stopped working afterward.
The good news: in most cases, the eSIM profile is still installed and the problem is only settings-related.
You may notice:
- eSIM shows signal but no internet
- No Service after reset
- main SIM using data again
- APN missing
- works on Wi-Fi only
This guide explains exactly why your eSIM is not working after resetting network settings, how to restore it quickly, and what to check before resetting again.
Quick answer: Re-enable Data Roaming, select the eSIM as your data line, restart the phone, check APN settings, and switch to LTE if needed.
1. Data Roaming Was Turned OFF
This is the #1 reason.
Many phones disable or reset roaming preferences after a network reset.
Travel eSIM plans often require roaming ON.
Fix:
- Open Cellular / SIM settings
- Select your eSIM
- Turn Data Roaming ON

2. The Wrong SIM Became the Data Line
After reset, many dual SIM phones automatically return mobile data to the primary SIM.
Fix:
- Select travel eSIM as the mobile data SIM

3. APN Settings Were Cleared
Some phones erase custom or carrier APN settings during reset.
Without correct APN values, data may fail even with signal.
Fix:
- Check provider APN instructions
- Re-enter APN if required

4. Carrier Registration Needs Refresh
The phone may need to reconnect fully after reset.
Fix:
- Restart the phone
- Toggle Airplane Mode ON/OFF
5. 5G Reconnected Poorly
After reset, the phone may prefer unstable 5G.
Fix:
- Switch Preferred Network to LTE / 4G

6. Wi-Fi Is Interfering With Testing
Many users think the eSIM is fixed or broken while Wi-Fi is masking the result.
Fix:
- Turn Wi-Fi OFF temporarily
- Test mobile data only
7. VPN or DNS Settings Changed
Some custom network tools are removed or altered after reset.
Fix:
- Disable VPN temporarily
- Retry without custom DNS
8. Main SIM Is Causing Conflict
Sometimes the home SIM resumes priority after reset.
Fix:
- Main SIM ON for calls if needed
- Main SIM roaming OFF
- Travel eSIM for data
9. Regional Plan Needs Arrival Country
If you reset before landing, some plans still will not connect until arrival.
Fix:
- Test again after arrival
