My daughter has a Samsung Galaxy Grand Prime phone supplied by Tracfone, so I don't think it is unlocked. I would like her to have the ability to text or call me if somehow we got separated at a museum or shop where there is no wifi service she can use (for Hangouts). We'll be there for 2 weeks so I think our best bet might be to either get a very inexpensive phone while we are there that is prepaid, or buy an inexpensive unlocked phone here to bring there and buy a European SIM card. Neither I nor my husband are comfortable finding and changing SIM cards, so the first option might be the best. Any suggestions for buying such a phone in London, perhaps in the Pimlico area or one of the major tourist areas that we might frequent? Or if you know about simple SIM cards/unlocked phone combinations I'll consider that too. Thanks in advance.
Update: I have just read that the FCC has worked out an agreement with Tracfone to allow them to unlock phones, so this seems like a possible option for us. We would then just need to know where someone has gotten a good SIM card deal in London. Perhaps the vendor could help us insert this. Thanks!
