I usually get 4 - 5 message per day there is no SIM card in my Galaxy S7. I turn my phone off or restart it; I take the SIM card out. I wait 5 - 10 minutes then reinsert the SIM card, power my phone back up, and this process works for a couple of hours. Then I repeat these steps throughout the day. What is going on with my phone?

    Thanks for any insight,
