Do unused SIM cards expire?


When 3.0 first kicked off, RW kindly sent me 2 SIM cards. I used one and still have the other. Would that 2nd SIM still be usable in a new phone or as replacement for a possibly faulty SIM in an existing phone?


The shelf-life of an unused SIM card is approximately 3 years, and an expiration date is printed on each (credit-card sized) card.


Thanks for that, Southpaw. I hadn’t yet removed the card from the folder, so hadn’t seen the date on the back.
