So how to get rid of this notification from your iPhone 6s?

There are only a few potential solutions you can try on in this case given that it’s concerning your wireless carrier. But before you give them a call, it is also worth giving a few things a try on your end. Outlined below are generic solutions and applicable workarounds you can try in order to fix the problem on your end.

First solution: Perform a soft reset or reboot your iPhone 6s.

A soft reset 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 6s:

  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 6s. 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 possible solution.

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 your SIM card.

This problem can also be tagged among other SIM card issues. Often times these errors can 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 6s:

  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.

Given that this problem can be associated with the network, resetting the network settings on the iPhone 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 6s:

  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.
