This is great, trying to transfer number from a different provider and get a message saying "O2 has found a problem with your existing mobile account". After a few phone calls I got put through to O2 who said they're having migration problems from other networks, try again in a few hours. No way. Workaround is to register as a new customer and ring O2 tomorrow with your PAC code!
