Knowing nothing about mobile phones I think I've now got to an age where I ought to keep one in the car just in case. I don't want one that gets the internet, just something that makes phone calls and messages with Pay As You Go that doesn't run out every month. So I buy the relevant sim card and stick it in an unblocked phone, is that it? Presumably the card comes with a number? I live in France but imagine it's the same procedure here but it's easier to read up about it on Amazon UK than try to translate everything on Amazon.fr ... or ask on here! ... :?
