hiya guys.
how long does a pay as you go sim card last?
ive got a vodafone sim card that i havent used for about 2 years and ive just gone to use it and it says number not in use.
if i put credit into it will it sort this problem out ? or do i need a new sim card?
i ask these questions because i dont want to put credit into it incase it doesnt work and i lose my credit.

cheers
