    Hi,
    I would recommend backing up all data and doing a hard reset.

    Here's how to do a hard reset:
    1. Turn off your phone
    2. Press Vol Down + Power + Camera buttons
    3. An exclamation mark will appear on the screen
    4. Press these buttons in the following order: Vol Up,Vol Down, Power, Vol Down

    Your SIM may have gone bad. Is there another phone you can try it in?

    ​Check with your carrier for a new SIM.
