Does the SIM card being locked affect calls and text messages?

The SIM card of the mobile phone card is locked, and the mobile phone cannot be used normally. Do not unlock it at will. You can only enter the password ten times. If the password is entered incorrectly for ten times, the card will be automatically locked and can only be replaced. When you buy a card, there will be a PUK code on the card. Under normal circumstances, you can enter the PUK code into your phone and unlock it. If you can't unlock it, take it to your mobile business hall immediately!
