Can phone out but not receive calls

[Bootneck107]

I was out this am but as soon as I returned home my S24 Ultra started playing music that I think I've heard before somewhere but I couldn't turn it off.  It went on for about 2 mins.  Not sure if it stopped or I did something to stop it.

Since then I've not  been able to receive any calls.  I can dial out and receive texts, messages, emails etc but just can't receive calls.  Restarted phone, checked Do not disturb but no luck.  Any ideas please folks ?

Hi
If a phone can make calls but not receive them, it's likely due to a problem with the receiving end of the phone call. This could be due to a variety of reasons, including the phone being on Do Not Disturb or Airplane mode, having call forwarding enabled, or issues with the phone line or service provider

If still have the issue
Contact your network provider

SORTED thanks.  I just took out the SIM card and put it back in.  Simples.
