[BigD]

Hi, 

I have tried the following 

removed cap

spoke to various o2 representatives 

can anyone assist

[BigD]

Sure, it was you who mentioned what’s app 

 yes o2 and what’s app are sep entities 

[BigD]

Thanks I’ll try o2 on X, as they are giving me the run around 

[BigD]

Really hard work o2 on X, don’t recommend it for those who value their sanity

Use Direct Message on X, I find them quite ok - so long as you keep poking periodically on the same thread... the link below has the way to do that, if you wish to persist.  Public messages ot O2 on X have disappeared into the ether, never to be seen again, @BigD.: https://community.o2.co.uk/t5/Other-Products-and-Services/O2-Web-Top-Up-not-recognising-a-valid-O2-P...

Hi, 

hope this helpful. 
went into an o2 shop, the guy was puzzled, explained all of the things I had checked. I have moved from virgin to o2 during the merge. As an outside chance he advised changing the SIM card, and it fixed it! I can now call abroad. Thanks for all of your suggestions

Great advice, @BigD - I guess the only advice not offered above was to visit an O2 Shop and do as you did 🤦🏻
