Is this a good question?

Try going back to your telecom company and have them replace your sim card. That will typically remedy the issue.

Well, there are some ways to try. You can try another SIM card. Turning the phone off and on. If it's a factory unlock, you can do a restore in iTunes, and you won't lose you factory unlock
