I have a Samsung Galaxy A51 with a SIM only O2 contract.
Just recently I've noticed that beside my Data icon a second icon keeps appearing of a handset with a small SIM with a number 1 in it. It signifies "Backup Calling" apparently.
Does anyone know what it means, is it detrimental and is there anything or indeed do I even need to do anything to stop it appearing?

I'd guess it was more to do with you using your sim in sim slot 1 and nothing to worry about at all.
