Why Is My eSIM Not Working After Changing APN?

If mobile data stopped immediately after an APN change, the new value is the leading cause. The phone may still show signal because network registration and internet routing are separate.

For a NoveSIM plan that requires manual APN entry, the APN is data.esim. Do not copy an APN from a domestic operator or another eSIM provider.

Keep the installed eSIM. Correcting the data profile does not require deleting or rescanning it.

Quick answer: Open the APN settings for the travel eSIM, select the provider-supplied profile or enter data.esim for NoveSIM, remove unsupported username and password values, save it and restart mobile data.

Confirm you edited the travel line

Dual-SIM phones can show separate network settings for each line. Verify that you are editing the NoveSIM profile rather than the home SIM.

Use the SIM selection guide if the labels are unclear.

Restore the NoveSIM APN

  1. Open the travel eSIM’s mobile-network settings.
  2. Open Access Point Names or Mobile Data Network.
  3. Enter data.esim in the APN field when manual setup is required.
  4. Leave username and password blank unless the order instructions say otherwise.
  5. Save and select the corrected profile.
  6. Toggle mobile data or airplane mode once.

Avoid mixing settings from different providers

APN values are not universal. A domestic carrier’s APN can register signal but fail to route data for a travel eSIM.

Do not change MCC, MNC, authentication or APN type unless the specific instructions require it. Save screenshots before editing further.

If the correct APN does not restore data

Confirm plan validity, destination coverage, the selected data line and required roaming setting. Then follow the no-internet checklist.

Contact NoveSIM support with the order number, country, device model and APN screenshots if the issue remains. NoveSIM plans are data-only.

FAQ

What is the NoveSIM APN?

When manual entry is required, use data.esim.

Why do I have signal but no internet?

The phone can register with a network while an incorrect APN prevents mobile-data routing.

Should I fill username and password?

Leave them blank unless the plan instructions explicitly provide values.

Do I need to reinstall the eSIM?

No. Correct the APN while keeping the profile installed.

Final Recommendation

Reverse the recent APN change first and use only the value supplied for the travel plan.

For NoveSIM, use data.esim, preserve the profile and then verify roaming, coverage and plan status.
