Why Is My eSIM Not Working After Factory Reset?

Q: What APN should be used if manual entry is required?

For restoring mobile data after a factory reset, use data.esim for a NoveSIM travel eSIM and leave unrelated fields unchanged.

A factory reset can remove an installed eSIM profile or its mobile-data configuration, and the original QR code may not be reusable.

The safest method is to change one setting at a time and keep the original installation information available on another screen.

Our travel eSIM is a data line for internet-based services. It remains separate from any line used for a local number, ordinary calls or carrier SMS.

Quick answer: follow the phone’s current menu and the original eSIM instructions; do not delete the profile unless support tells you to.

Know when support is needed

Data needs for restoring mobile data after a factory reset are driven by activity: navigation and text are usually modest, while video, cloud photo backup, system updates and hotspot work can use the allowance much faster.
