PAYG sim, data working in Europe but unable to make or receive calls or texts on three different SIMs. We have text TRAVELON to 21300 and received confirmation it is activated.
I have swapped the cards out to another family member's phone which is also PAYG on O2 which works fine, and they do not work on that phone whilst that SIM works fine in the other handsets.
Do you think it must be faulty SIMs? The three that do not work were ordered together, but about a month after the one that works. O2 are useless for assistance!
I'm thinking of going back to EE for all four SIMs, they have much better customer support, and you don't get the annoying "in plan" notification before every call!
