I've kept them a year or two before use with no problems. Not safe with EE SIMs, though. They do expire.To clarify I am aware there is a 24 month maximum usage from once activated. However I have read though amazon questions and some say that it must be activated within 6 months of purchase, others say there is no expiry on the activation date. Can anyone confirm from experience that there is no expiry on the required activation date.
