Unsupported SIM

Hello, I have an iPhone 7. When I insert a new SIM card, it says "SIM not supported." I don't understand; can you help me solve this problem?

    Hello
    It is probably a locked phone. It only accepts SIM cards from one operator. You need to check with that operator to unlock it.

      @PharasseI have no solution.

      I still advise you to insert the SIM card into another smartphone to ensure that it is not a problem related to the SIM card. If it works in the other smartphone, then it will indeed be an issue with the iPhone.
