As these cards age out, the cellular standard that they support will be eventually dropped and then they won’t work. Just like owning an old cell phone.
This has happened with 3G networked and older vehicles (OnStar has been a thing since the 90’s). People tried to unplug the OnStar hardware but they ran it through a CAN bus and it would disable the car (to prevent thieves from circumventing it).
