Calling fault with particular number

[Tom87]

Have an issue with my pay monthly sim. Everything looks normal. When I make or recieve calls the call connects but I can't hear them and they can't hear me.

Other Sims work just fine in the phone.

Went into the O2 store and got a new sim, transferring my number and plan to it.  However I still have the same issue!

Any ideas on help would be appreciated.

We’re just customers like you but it sounds like you’ll need someone to access your account which can’t be done from here. If you message O2 using the links below, they should be able to help you with this

or give them a call on 202  or 0344 809 0202
