Why is this happening?

Essentially what’s happening behind the scenes is your SIM card trying to get back to the carrier to get an update. So each time the SIM card tries to get in touch with the carrier’s update server, you’ll see this message on your screen.

However, if it keeps happening repeatedly, it can indicate some issue with the update process. The issue can be at either end, but since you can only control your device, we’ll be going over fixes that address the issue at your end.

How to resolve the error?

You can try the following solutions to see if they fix the “Your SIM sent a text message” issue.

Restart your phone

One of the most popular and easy solutions to pretty much every network related problem, be it cellular, or WiFi is to reboot your iPhone. Rebooting any device for that matter can fix several seemingly random issues.

Eject and re-insert SIM card

The next thing is to remove the SIM card from your phone and re-insert it in the device. This allows you to physically inspect the SIM card for any physical damage or scratches on the metal contact, which might be causing the problem.

Manually check for Carrier Settings Update

If the automatic update settings aren’t working, you can manually update your carrier settings to see if that resolves your issue.

  • Head over to iPhone settings and tap General.
  • Tap About.
  • Wait for a minute and if you see a prompt stating you’ve got a carrier settings update, tap the Update button to install said updates.

Now restart your iPhone, and the error shouldn’t show up again.

Reset iPhone network setttings

Resetting iPhone network settings can help refresh any corrupt or bad settings that may be causing this problem.

  • Scroll down and tap on General.
  • Tap on Reset.
  • You’ll find a Reset Network Settings button there. Tap on it to reset your network stack.

Now restart your iPhone, and the error shouldn’t show up again.

Contact your carrier

If nothing else works, your best bet is to get in touch with the customer support from your wireless carrier and figure out the exact problem. Chances are there’s some issue on their end that will be resolved in due time.
