Can't message or phone other o2 numbers

This is an odd one:

I can phone and message other mobile providers (including landlines)
But if I send a message to an o2 phone it never arrives (my family are all on o2),
also if I phone another o2 number it rings once and goes straight to voicemail (they never recieve anything)

I have no problem recieving calls from o2 numbers

As mentioned can phone landlines without a problem and other mobile phone on different networks.

Any suggestions on what todo welcome

It is an odd one. Certainly all those people on O2 wouldn't have blocked you, so I think you need a new sim

Pop in to any O2 store and they will give you a new one and swap everything over for you

Best of luck and welcome to the forum Welcome

Have you recently ported your number into O2 ?

you may have a problem with your account that tech services need to resolve. 

I’d call 4445 and ask customer service to escalate to 2nd line support. 

I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues.
