Just spoke to my son (I'm away from home) - at home there are 3 phones on O2 PAYG, his is working, the other two not. So can't be a power outage or water damage .. obvious I know. Sounds like some central computer system somewhere has lost or corrupted a large number of customer accounts. So our phones don't connect ? Makes you wonder when LinkedIn was hacked recently & 6 million account details were obtained. ... paranoid, me ? 🙂
