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.

O2 say nothing they can do so have to go elsewhere.
Great! Been an O2 customer for 15 years!

Best option to be honest. Try some free other network sim cards in your phone. I wouldn't be struggling with O2 if they can't help sort their network out in your dstrict.
