Repeated eSIM disconnections usually point to unstable network registration, weak coverage, automatic data switching or a phone power setting—not a profile that needs to be deleted.
Note where the dropout happens and whether the signal disappears or only data stops. That distinction changes the diagnosis.
NoveSIM plans are data-only, so test with Wi-Fi disabled and a browser or map open.
Quick answer: Lock mobile data to the travel eSIM, disable automatic data switching, keep network selection automatic, enable roaming on the travel line and remove battery restrictions from essential apps. Refresh with Airplane Mode; do not delete the eSIM.
Is It Signal Loss or Data Loss?
If bars vanish while moving, the phone may be handing over between cells or entering weak coverage. If bars remain but pages stop loading, check the selected data SIM and APN. Use the connected-without-data workflow for that second case.
Stop the Phone Switching Lines
- Select the travel eSIM as the only mobile-data line.
- Disable Cellular Data Switching or automatic data switching.
- Keep roaming off on the home SIM.
- Enable roaming on the travel line when required.
- Restart and test with Wi-Fi off.
On Android, aggressive battery saving can suspend VPNs or apps and look like a network dropout. Test without Data Saver or extreme power saving.
Check Network Registration
Leave operator selection automatic first. If disconnections occur only on a train, road or inside one building, location is the likely cause. Manual selection should use only a partner supported by the plan.
Confirm the current plan remains valid and has data. If manual APN entry is required, use data.esim as explained in the APN guide.
When to Contact Support
Record times, locations, displayed network and whether Airplane Mode restores service. Send that evidence to NoveSIM Support without exposing the QR code.

FAQ
Why does my eSIM disconnect while travelling?
Cell handovers, tunnels and weak coverage can interrupt registration temporarily.
Can dual SIM cause switching?
Yes. Automatic data switching can move traffic to the other line.
Will resetting network settings help?
It can be a later step, but it also removes saved Wi-Fi and related settings; try targeted checks first.
Should I reinstall the eSIM?
No. Do not delete it unless support instructs you.
Final Recommendation
Separate radio dropouts from data-only failures, stop unwanted SIM switching and test across locations. Preserve the profile and give support a clear timeline if instability continues.
