An eSIM that keeps disconnecting is usually losing network registration, switching data lines, moving through weak coverage or using a setting that does not match the travel plan.
The useful clue is when the drop happens: while stationary, after moving location, when the screen locks, or when a second SIM becomes active.
Do not delete the eSIM. Profile deletion can remove useful evidence and may prevent reinstallation unless NoveSIM Support specifically authorises it.
Quick answer: Confirm the eSIM is enabled and selected for Mobile Data, turn on Data Roaming for that line, disable automatic data switching and leave Network Selection on Automatic. Then refresh registration once with Airplane Mode and test a normal website.
Why Does My eSIM Keep Disconnecting?
If signal bars disappear, the phone is losing network registration. If signal remains but websites stop loading, follow the signal-but-no-data checks. If only hotspot devices disconnect, use the hotspot troubleshooting guide.
Stop the Phone Switching Data Lines
- Open the mobile or cellular settings.
- Select the travel eSIM for Mobile Data.
- Turn off automatic mobile-data switching.
- Keep Data Roaming off on the primary SIM.
- Enable Data Roaming on the travel eSIM when required by the plan.
On a dual-SIM phone, the primary line can remain enabled for its number, but calls, SMS and voicemail remain subject to the home carrier’s roaming rules.
Refresh Network Registration
Leave Network Selection on Automatic, switch Airplane Mode on for about 30 seconds, switch it off and wait several minutes. Restart the phone once if the connection still cycles. Avoid repeatedly selecting visible carriers because a network can appear in the list without being authorised for the plan.
Check APN and Plan Status
Confirm that the plan is active, valid in the current country and still has data. If manual APN entry is required for NoveSIM, use data.esim with username and password blank. The APN guide shows when this setting matters.
When to Contact Support
Record the location, exact phone model, operating-system version, displayed signal, selected data line and whether the failure follows movement or a second SIM event. Send safe screenshots without exposing the QR code or activation credentials.

FAQ
Why does my eSIM disconnect when I move?
The phone may be changing cells or entering weaker coverage. Use Automatic Network Selection and test again in a second location.
Can dual SIM cause connection drops?
Automatic data switching can move traffic between lines. Select the travel eSIM manually and disable switching while testing.
Should I reset network settings?
Use it after simpler checks because it may remove saved Wi-Fi and network preferences. Record current settings first.
Should I reinstall the eSIM?
No. Do not delete or reinstall it unless NoveSIM Support specifically instructs you to do so.
Final Recommendation
If your eSIM keeps disconnecting, treat the timing and location as diagnostic evidence rather than deleting the profile.
Stabilise line selection, roaming, network registration and APN one step at a time.
If the drops continue, send Support precise details so the failure can be distinguished from a local coverage gap.
