A (Belarussian) relative is staying with me at the moment & wants to buy a mobile while in the UK as the prices are much cheaper. If we buy a PAYG phone will she just be able to take it back home & stick a local sim card in, or will we need to go through some kind of 'unblocking' procedure?
In case it makes a difference: I expect we'd like to put the UK sim card that comes with the phone in first, just to make sure everything functions correctly. (It comes with £10 free credit.)
(And sorry this is such a basic question - I'm one of those people who only changes their mobile every 4 or 5 years!)
