Fairphone 4 sim not recognised

I have a problem with my Bsnl Sim not being recognized. When I remove it and put it back it works for a while and then same problem starts.

It started about 1 month ago when I returned from abroad where I had used an esim.

I removed the esim.

What s the problem and solution?

Thank you.

Try Settings Search: Access Point Names > top right menu > Restore default.

Turn to Airplane mode, wait a few seconds. Return to mobile network will force a new connection.

Some sources suggest that the above technique should be done while a good Wi-Fi connection already exists.
