What causes iPhone SIM card errors?

Due to using a Locked iPhone
In Japan, some carriers provide SIM cards that can only be used for phones distributed by that carrier and only use the carrier's network. If you use a Locked iPhone (a type of iPhone that only responds to SIM cards from a specific carrier), you also cannot insert a SIM card from another carrier.
SIM card slot filled with dust
The SIM card slot is where you insert the SIM card into the iPhone. After some time of usage, dust and dirt may accumulate in the SIM card slot, causing improper contact between the SIM card slot and the device, resulting in the iPhone not recognizing the SIM card.
Incorrectly cut SIM card
Poorly performed SIM card cutting operations lead to cutting the SIM card to the wrong size or cutting into the SIM card's chip. Incorrectly cutting the size leads to improper insertion into the SIM card tray, and cutting into the SIM card's chip affects the SIM data on the iPhone.
