Not entirely.
The thing is, the SIM itself is a microcontroller running its own software - and, possibly, applications from the SIM provider. Therefore, it is possible for the SIM itself to “crash” or “hang” - which could give rise to this kind of thing…
One thing to check would be whether it is more or less frequent with any particular SIM(s)…
Plus, of course, the SIM interface relies upon mechanical contact - which is a further source of problems beyond the module’s control.
(unless you’re using an InSIM, of course)
