The cellular performance is fine with 7.1.2 and a carrier settings update for me.
Is there any damage to the SIM card, or is the SIM card old, or cut to size?
- Try start up the phone without the SIM, clean the SIM with a dry cloth, shut down the phone again, reinsert the SIM and start up the phone. Select Yes to apply operator settings and reboot if requested.
- Please consider a replacement SIM if the phone still does not work as expected.
