Sim stopped working

[NEV.54]

I moved my sim card to my old phone Samsung A53 5G from my new phone Samsung S24 Ultra, so I could send away for screen repair. I cannot connect to any networks now and can only communicate on WhatsApp when using WiFi. Whenever I try to make a call I get a message saying "Not registered on network" I tried putting sim back in S24 but still not able to get on network. I cannot call Sky to get technical help,as get same not registered message.

Was the A53 from Sky ?

[NEV.54]

Yes from Sky. Can't call for help as phone won't allow me to make any calls using network. Can't find option to chat to anyone to sort or ordering replacement sim.

Have you trying getting the network settings sent to the phone ?

This should be what you need to do:

Go to sky.com/networksettings (My Account > Mobile > Settings) and sign in with your Sky iD.
Select the mobile number or SIM name you're having trouble with.
Scroll to 'Resend network settings' and select Request settings.
Save the settings when your receive them and reboot your phone.
