Calls not coming through

[Nb]

Hi. My last phone was being temperamental with calls and was not always ringing. I got a new phone and now it is doing it with this one. I presume it isn’t the phone now. Sometimes people say it goes straight to answerphone. Why is it mossing calls and not ringing my end?

Did you get a new SIM with your phone?
If not, pop into your local O2 shop for a free SIM swap.
It may also be a network issue but I'd try the new SIM first.

Hi @Nb Have you checked your network status? https://status.o2.co.uk/

Also, when you got your new phone did you use the old sim or the new one?

Hi @Nb, how are you getting on at the moment? Sorry to hear you've been having issues with receiving calls. Have you noticed any improvements since you last posted? Any help from the above replies from @Cleoriff and @MI5? It would be lovely to hear back from you.
