1:  Give a Restart to Your Phone

Like on Android, restarting the iPhone may often fix any number of issues. Restarting your device is the very first step you should take when you encounter any problem, glitch, or issue before seeking answers online. It’s a no-frills fix, but it works like a charm most of the time. Without further ado, proceed as follows:

  • To power off your iPhone, just move the red slider. Wait a couple of seconds.
  • In the end, click the Sleep/Wake button once again, this time keeping it held down until the Apple logo displays on the screen.

If rebooting the device has already been attempted without success, it’s time to move on to the next possible solution.

If you’ve repeatedly dismissed the “Your SIM sent a text message” warning, it may be time to change your carrier’s settings. Changing your carrier settings is as easy as following these instructions.

  • Next, Tap on About and Wait for a Second
  • In Case Updates are Available, You’ll See a Popup with “Carrier Settings Update”

If the update notification does not appear within 30 seconds, then the update is not currently available.

3:  Reset Network Settings

Many problems with your network can easily be fixed by resetting your network’s settings. Keep in mind that resetting your network settings might wipe out all of your connection preferences, so think twice before you attempt this.

Stop and give it some consideration before continuing. If you are all set to go, here’s what to do next:

The SIM tray is often located on the left side of the iPhone, next to the power button. Here are the procedures you need to take to remove your SIM card:

  • You should remove the SIM card and power off your iPhone.
  • Reinsert the SIM card into its slot and power up the device.
  • Determine whether the “your SIM sent a text message” problem is gone or not.

5:  Contact your Service Provider

Test to see whether the iPhone’s SIM message popup still appears after you’ve gone through the solutions mentioned above.

If you answered yes, the problem might be on the part of the operator. You may contact the SIM service provider to find out what’s wrong and how to fix it.
