How does the eBay sellers to keep the sim unexpired without opening it?

[kunhoho]

I just bought 2 numbers that want to keep it as a gift to family that they will come to UK next year. Is there anyway to keep the cards unexpired without opening it? How can the eBay sellers do that? Thanks for the help.

@kunhoho  don’t set them up don’t use them leave them in the package and they won’t expire.   They only do this with numbers that are no longer being used these haven’t been used or registered.

Thanks Chris! So if I don't register it / use it, supposing it should last at least 1 year? Thanks mate

Hi there @kunhoho 

If you check the outer packaging on the SIM cards you have purchased it should indicate an expiry date. 
SIM cards that have yet to be used/registered tend to have a decent timeframe for customers to use them, but please be aware that they will expire at some point.
