Hi, please help. My S20 FE updated to android 13 on Sunday and since then I've been without a mobile signal, data etc. WiFi is fine.
Been onto Vodafone and no joy, they said no issues with network. Tried SIM in an old phone and it works fine. I've now put the SIM back in my normal phone in the SD card slot/ SIM2 and it works!! Any ideas as to why SIM slot 1 has suddenly stopped working? I've tried making a call and it comes up with the error " not registered to network ". Any settings I need to check? Would obviously like to use the phone with the SD card, which currently I can't! TIA.
