I lost my phone recently, reported it lost to the phone co and went into a shop to find out what to do next. They offered me a sim-only deal on my existing contract which I accepted, but now I have to get a handset. If I buy one online (which I'm assuming will be cheaper than in a shop) do I just put the sim in and it all just works? Or do I have to get the phone co to 'link' the sim (and therefore my contract) with the phone? Will they do that if I haven't bought the handset from them? The number was blocked when I reported the phone lost but they assure me the new sim has the old number on it so do I get it unblocked or will that happen automatically when it goes into the phone?
Sorry for the daft questions but I always feel so intimidated by the staff in these places and forget to ask all the relevant questions! I want to avoid having to go back if possible.
