Unable to call other o2

[Mots]

I can not make or receive calls to or from other O2 users.

Calling or recieving calls from friends on other networks work fine, it's only O2 network affected.

Called O2 support and they have no idea.

Any ideas ?

Did you come to O2 via Virgin or a port-in from another network, @Mots? If the first, are you still using a Virgin SIm? If the second, is your port-in complete?

O2 Social Media Team is on the link just below, give them a chance to look.

@Mots 

You're account will need checking.

Maybe an incomplete port if you've recently joined?

This is a customer to customer community, not O2.
You need to contact O2.
Message them on Social Media. Facebook (https://o2uk.co/O2CFB) , Twitter (https://o2uk.co/O2CTW) or Instagram (https://o2uk.co/O2CIG) or give them a call on 202 or 0344 809 0202 (contract) 4445 or 0344 8090222 (PAYG)

Been with O2 for 12 months now, problem only started a week ago. 

I've contacted customer service, they didn't know how to fix it

I moved to O2 from Three 12 months ago, this is a recent problem..

Ask customer service to escalate your issue if they don't know.

Got a new SIM card, all sorted...

Good job, @Mots - they can fail in unexpected ways, SIM cards. 🙄
