Your SIM sent a text message

And you won't see it again. If you still get the message from now and then, you can take the next guide to solve "Your SIM sent a text message" problem.

Method 2. Restart your iPhone

Updating your carrier settings won't restart your iPhone. Many problems can be resolved by restarting iPhone (same situation exists anywhere, like computer, TV, even lights…), because that will refresh the data on it. Don't tell me you don't know how to restart your iPhone. I don't believe it.

Method 3. Re-insert your SIM card

"Your SIM sent a text message"… This problem happens because there's some communication between your iPhone and your carrier. So it may work to eject and re-insert your SIM card to your iPhone.

Method 4. Reset network settings

This is not a highly recommended way. Resetting your network settings may stop the message "Your SIM sent a text message" from popping up. But the cost of this possibility is to reset all the settings of your network, including Bluetooth, cellular settings, WIFI, VPN, etc.

If you still want to do that, just go to Settings - General – Reset – Reset Network Settings, then enter your passcode.

Compared with this risky operation, I prefer choosing a safe way to fix this problem, just as the following method.

Method 6. Call your wireless carrier

It has a great possibility that your wireless carrier will help you stop the message showing up. Just make a call and tell them your problem, they will tell you how to do that. Here we take AT&T: as an example. Anyway, it happens most with AT&T users… A friend online has shared the steps that AT&T: had told him.

  • Steps:
  • • 1. Go to settings – Messages, turn on iMessages and Send as SMS.
  • • 2. Go to Settings - General – Reset – Reset Network Settings. Yes, same operations as method 4.

Actually I don't know the reason. But you can have a try or call At&T by yourself.

It's number is 1-(800)-331-0500.

Method 7. Update your iOS version

From our survey we have found that "Your SIM sent a text message" problem happens mostly in iOS 8, more specifically, iOS 8.2.

Method 8. Reboot your network equipment

Just as we said in method 2, restarting is always helpful. Restarting your network will refresh the network data. Compared to method 4, rebooting your modem or wireless router is much safer.

1. Completely turn off your modem or wireless router.

2. Unplug the power cord or unplug the network cable.

3. Wait for at least 30 seconds.

4. Plug them back and turn on your modem or wireless router.
