Does a new unactivated SIM card have an expiry date?

[hyT]

I often read that some community members keep spare SIM cards for referrals. Do they have a best-before day?

I was given free Bell SIM cards when I bought unlocked phones from retail stores. I also had free SIMs from other providers when they had promotions. Are they useful after a few years?  Just curious.

No expiry date if they have never been activated. Although some older sim cards may not be as useful as older sims could just be the regular big sim card (although there's YouTube to show you how to cut those sims to smaller sizes). Where the newer cards are 3 punch.. meaning regular sim , micro sim and nano sim so they fit on pretty much all phones.
