My SIM card is not recognized by the system, neither under Linux nor under Windows. What could be the reason?

1. Possibility: All-In-One SIM card

This is probably due to the fact that you have an "all-in-one" SIM card, whereby the SIM can be broken out into two other small SIM sizes (Micro and Nano). Unfortunately, they are not always compatible with the eject mechanism and therefore do not fit perfectly, so they cannot be read.
In this case, it is advisable to obtain a more stable adapter elsewhere and, if necessary, to stabilize it with a tesa strip on the upper side.
