Used to have a payg a/c with t-mobile and topping up if and when in need. The good thing was that credits not used by end of month are carried over.
I can't seem to find one now with any provider that will allow unused credits to be carried over at the end of the month. If you know of one pls post back. Would be much appreciated
Reason I have a second phone that I would like to use on this basis.
