    @EE @O2 @ThreeUK How can I find out whether an old iPhone 5S is locked to a network? Thanks

    @O2 How long does it normally take for your head office to respond to a formal complaint ? It’s been a week so far and nothing (Should not really be surprised as O2 customer support is useless). Just waiting to go to the ombudsman .
