I haven't got a smartphone just a very basic call/text thing and I really haven't got a clue about it all. Ds wants to take his smartphone on our California road trip and I've come round to the idea that it would be useful to have but I keep hearing stories about people coming back to huge bills. I've gone into debt to have this holiday - our first for years - so I really can't afford any unexpected charges.
How do I avoid extra charges? Will we need a code to enable the phone to work? Which provider is best for this sort of thing? Ds is coming to the end of his contract so we could switch before we go.
