Possible workarounds to stop your iPhone SE from showing you this alert message

Considering the fact that this problem is most likely tied to your carrier or network service provider, you only have a few options to try doing on your end. Even so, these few options can likely get the issue resolved. Otherwise, you always have the option to call your wireless carrier. But before you do, try performing the following methods to troubleshoot the problem on your end. After you have exerted all your efforts and still couldn’t get rid of the message,  then that is the time you should give customer care a call for help.

If possible, try to reboot your power cycle your modem or wireless router before you proceed with any of the following procedures. Doing so will refresh the connection between your network equipment and network tower, so as with your other connected devices in your home network.

First solution: Perform a soft reset or reboot your iPhone SE.

A soft reset simply means rebooting your iPhone. Your iPhone does not restart automatically after the carrier settings are updated. This is how carrier settings update differs from other software updates and resets. So even if you already have updated the carrier settings on your iPhone, your SIM card might still get stuck on texting your wireless carrier. Aside from giving your iPhone a fresh start, turning your device off and then back on may likewise break the endless loop of texting by your SIM card.

Here’s how a soft reset is properly done on your iPhone SE:

  1. Press and hold the Sleep/Wake button (Power button) until the Slide to Power Off slider appears.
  2. Drag the red power icon from left to right off your screen to power off your device.
  3. Wait for about 30 seconds.
  4. After the elapsed time, press and hold the Sleep/Wake button again until the Apple logo appears.

Your iPhone will then boot up. Usually the message will no longer show up after the reboot but if it persists, proceed to the next solution.

Second solution: Check for carrier settings update and update, if necessary.

Your wireless carrier periodically rolls out carrier settings update as their way to improve your iPhone’s ability to connect with your carrier’s cellular network. If you think you haven’t done it already, try to see if a carrier settings update is available for your iPhone SE. Here’s how:

  1. Tap Settings from the Home screen.
  2. Tap General.
  3. Tap About.
  4. A pop-up message saying Carrier Settings Update will appear a few seconds later if an update is available. If you see this message, tap Update.

If after 30 seconds you are not seeing the message, then most likely there is no update available yet. You may then proceed to the next applicable workaround.

Apple also rolls out carrier settings updates but in a different procedure so that the SIM card will not have to send a text message to update itself. So that shouldn’t cause you this trouble.

Third solution: Remove and re-insert the SIM card on your iPhone SE.

This problem can also be related to a SIM card issue. Should this be the case, it can likely be remedied by removing and re-inserting the SIM card on your iPhone. Doing so will give it a fresh start and allows your SIM card to reconnect to your wireless carrier’s network. Here’s how to remove and reinstall the SIM card on your iPhone SE:

  1. Locate the SIM tray on your iPhone, which is on the left side below the Power button.
  2. Insert the SIM card ejector tool or small paper clip into the small hole at the bottom of the SIM tray to eject your SIM card.
  3. Gently pull the tray out, then remove the SIM card.
  4. Check the SIM card for any signs of possible damages like scratches or dents. If there’s none, place it back into the SIM tray the same way it was removed.
  5. Put the SIM tray back into place.
  6. Turn on your iPhone then see if the message still shows or not. If it still pops up, try the next option.

Fourth solution: Reset Network Settings on your iPhone SE.

Again, this error can be also be regarded as a network issue and so, resetting the network settings on the iPhone SE can potentially fix it. When you reset network settings on your iPhone, all pertinent information will be reset to factory settings. So all your saved settings for Bluetooth, Wi-Fi, VPN and cellular network will be erased in the process. With that said, be sure to take note of your Wi-Fi network and password as you need to re-enter this information afterwards. What you will possibly get in return is that it will fix any glitch that may have caused your SIM to send texts on an infinite loop to your wireless carrier. Here’s how to reset network settings on your iPhone SE:

  1. Tap Settings from the Home screen.
  2. Tap General.
  3. Tap Reset.
  4. Select the option to Reset Network Settings.
  5. If prompted, enter your passcode.
  6. Tap Reset Network Settings to confirm action.

Your iPhone will then reboot once the network settings has been reset to factory defaults. You may then set up your Wi-Fi networks again then try to see if you’re still getting the same message on your iPhone.
