Say I have a Tesco Mobile phone and I buy €50 credit for it, but only make 1 phone call per week, say 50c per week. After 6 months I'll have used about €13 of the original credit, does he remaining €37 expire after 6 months (or whatever length of time?) or does it remain "credit" until used up.
Do I have to purchase a minimum amount of credit per month to keep my original credit?
