What’s the reason? It usually happens when there’s a SIM card activity or issue between your SIM and the service operator. You may experience it after swapping SIM cards or updating your iPhone. This issue is prevalent with users on Airtel.

Below are some handy tips that will help you stop the SIM card from automatically sending SMS messages on your iPhone.
