All the phones I have used were like this (Samsung, Google, Xiaomi, Redmi, Oppo - across years and years of models).
I am surprised you write that the SIM is locked upon reboot. What does this mean in technical terms? Do you mean that you have to enter the SIM PIN when your phone reboots?

I can cancel the popup and then still use the rest of the phone, but when I do that I have no cellular network access until I unlock the SIM itself. For the avoidance of confusion, the SIM PIN is independent of the phone PIN.
- BrandoElFollito 2y agoAh, 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.
