Hi folks,

Really hope someone can help! My Fold 4 is c.18momths old and just today has started to refuse to connect to any cell network, allowing only emergency calls & WiFi Calling.

It is the same issue for both physical SIM slots and with 2 different carrier SIMs tested - both tested SIMs work in an iPhone without problems. SIM 2 slot is worse as not even emergency calling is possible.

I have tried resetting mobile data configs, hard restart, restart into safe mode and enable only mobile connectivity with all 3rd party services and unrelated background tasks disabled.

I have also tried resetting the phone to factory settings and still nothing.

My device model is: SM-F936B/DS.

OS version is: One UI 6.1

Android version is: 14

I really hope someone can help! Tha KS in advance for any advice.

Cheers,
