When your service agreement expires, you will continue service on a month-to-month basis. Your service will not be interrupted due to your service agreement expiring. If you need information on when your service agreement expires, please contact Customer Care for further information

If your card is expired then Dial 611 for assistance but you card is prepaid sim, it may be expired which would require you to buy a new sim card. Normally any service providers card ( AT&T,VERIZON,ALLTEl,Cingular) will get expire if you dont recharge it or use If for a certain amount of time, the sim will expire along with the phone number it held.

Even if your card is expire it will not given to a new customer for certain period of time i suggest you call customer care first to check the status of your sim card, if they say its available then just pay the activation charge and reactivate your card. if its not available then go here to purchase a new one.
