    Quite shoddy of @O2 to refuse me a contract as a new resident of Northern Ireland when my driving licence is in the Republic of Ireland and not offer an alternative verification or reply to my email of complaint from 6 days ago.

    @O2 Hey I've just moved to your network and submitted my PAC code and number from my old contract. Today is the first day I've switched my phone on with the new sim card, is the switch automatic or do I need to do anything else?
