They usually expire about 5-6 weeks after the last recharge but this will change with the amount of credit you add. To check enter *888# and hit call. If it does not show any credit it is no good. They expire and are not chargeable about 3 days after the expiry date and are good for the bin. I used to use a mob called top2mobile to recharge my sims from Australia but they now do not accept Paypal or an Australian credit card so I now use https://www.mobilerecharge.com and so far they have been good without hassles. Moreno yours will be in the mail later today.
