RTP Voice Data Stream Breakdown

My wife’s iphone can make and receive calls but there is a total absence of sound!  Switched SIMs with my iPhone and the fault followed the SIM.  Have logged two faults through My O2.  Can I do anything else?  What’s the typical wait time for a reaction and  am I eligible for a  refund for days without service?

Thanks in anticipation.

If the fault followed the sim, it would be quicker to get a new sim from a local store.

Take ID with you and ask them for a new sim. They will do a sim swap for you

Hope that helps.
