My friend travels a lot to the uk but is mainly based in france. Sometimes he travels to spain and germany and needs to make a quick call to france. He has a lot of uk contacts but when he needs to call them in the uk his french sim doesn't work and those that do are very expensive. Ideally he needs one where people from the uk can contact him if they want without getting a hefty connection charge (this isn't necessary but would be ideal.. :)
Which uk phone company has either a goood international rate or free roaming charges (vodafone would be useful but they're only doing it for the summer. Ideally he'll need one
So just to summarize he makes hardly any phone calls in france with his mobile, but the charge of the phone call should be reasonable if he calls a french number,
Minutes are key because when he's in the uk he can call landlines/mobiles. People calling him from the uk and him calling people to the uk on a mobile would be a bonus but can always use skype or buy a cheap phone.
Hope this wasn't too complicated.. thanks in advance..
