An eSIM that works briefly and then stops has already proved that installation can succeed. The likely problem is now plan status, network registration, data-line selection, APN or a phone setting that changed after the first connection.
Do not delete the installed profile. Work through one check at a time so you can identify whether the interruption follows a network handover, depleted allowance or device power setting.
NoveSIM travel eSIMs are data-only, so test service with a browser or internet app rather than a conventional call.
Quick answer: Confirm that the plan is still active and has data, reselect the eSIM for mobile data, disable automatic data switching, use automatic network selection and check the APN. Then refresh registration with airplane mode or one restart.
Check whether the plan stopped
Open the order or account and review remaining data, expiry and any fair-use condition. A connection that ends after a precise amount of use may indicate depletion or a plan limit rather than a phone fault.
If consumption looks unexpectedly high, follow the background-data checks before adding more data.
Make sure the data line did not change
- Open SIM or mobile-network settings.
- Confirm the travel eSIM remains enabled.
- Select it again for mobile data.
- Disable automatic cellular-data switching.
- Enable data roaming on the travel line where required.
The dual-SIM switching guide shows how calls and data can use different defaults.
Refresh network registration
Leave network selection on automatic first. Turn airplane mode on for about 30 seconds, turn it off and allow several minutes for registration. Restart once if the line still does not reconnect.
If failure follows a border crossing or movement between regions, confirm that the destination is included and use only a partner network named in the plan instructions.
Check the APN without deleting the profile
If manual NoveSIM APN entry is required, use data.esim. Remove incorrect extra APN values rather than copying settings from a domestic operator.
For signal without usable data, follow the connected-but-no-internet sequence.
Look for device restrictions
Data Saver, Low Power Mode, per-app cellular restrictions or a VPN can make service appear intermittent. Test a simple webpage with those restrictions temporarily disabled, then restore only what is needed.
Do not reset all network settings as a first step; it can remove saved Wi-Fi and other configurations without addressing an expired plan.

FAQ
Why did the eSIM stop after one day?
Check expiry, remaining data, fair-use conditions and background consumption before changing phone settings.
Can automatic SIM switching cause this?
Yes. The phone may move mobile data back to the home line. Select the travel eSIM and disable automatic switching.
Should I reinstall the eSIM?
No. Keep the profile installed and check the plan, network, data line and APN first.
What APN should NoveSIM use?
When manual entry is required, use data.esim.
Final Recommendation
Treat a once-working eSIM as a connection or plan-state problem, not an installation failure.
Preserve the profile, verify allowance and validity, then correct the selected line, network registration and APN in that order.
