Ah, this is the normal behaviour of a SIM card. You can disable this PIN at startup (a setting in the phone). This is not recommendable, though, because if your phone gets lost or stolen your SIM may be used in a "layer" (a device that will make premium calls or SMS, the name is derived from a hen (that lays eggs)).
The solution is to use an eSIM - you can disable the PIN at bootup because it is protected by the phone lock anyway and will be operational immediately.
