Contact your mobile carrier

You’ll need to borrow another phone or visit a store in person to get help from your mobile carrier, but it may fix the issue. If there’s a network outage in your area, you’ll simply need to wait to reconnect. Or, if you need a new SIM card, your carrier can replace it for you.
