iPhone Cellular Error? Here’s The Real Fix!

There’s a Cellular error on your iPhone and you don’t know why. No matter what you do, you can’t get Cellular Data to work. In this article, I’ll explain how to fix the problem when you experience an iPhone Cellular error.

Turn Off Airplane Mode

When your iPhone is on Airplane Mode, it can’t connect to cellular networks. Let’s make sure that’s not the case.

  1. Open Settings.
  2. Tap the switch next to Airplane Mode. You’ll know Airplane Mode is off when the switch is white and positioned to the left.
  3. If Airplane Mode is already off, try turning it on and off again to see if that fixes the problem.

Check For A Carrier Settings Update

Carrier setting updates are less frequent than iOS updates, but they help connect your iPhone to your carrier’s cellular network. It’s possible you’re experiencing an iPhone Cellular error because the carrier settings need to be updated.

To check if a carrier settings update is available:

  1. Open Settings.
  2. Tap General.
  3. Tap About. If there’s a carrier settings update available, you should get a notification within 10 seconds.

  2. Tap General.
  3. Tap Software Update.
  4. If there is an update available, tap Download and Install.

Eject And Reinsert Your SIM Card

The SIM card is what allows your iPhone to connect to your wireless carrier’s network. If there’s an issue with your SIM card, you might experience Cellular errors on your iPhone.

Turn Off Wi-Fi Calling And Voice LTE

Some iPhone users have had success fixing Cellular errors by turning off Wi-Fi Calling and Voice LTE. Both are great features, and we recommend that you avoid turning them off unless absolutely necessary.

It’s also important to keep in mind that some carriers don’t offer these features. If you don’t see these settings on your iPhone, move onto the next step.

To disable Wi-Fi calling:

  1. Open Settings.
  2. Tap Cellular.
  3. Select Wi-Fi Calling.
  4. Turn off Wi-Fi Calling on This iPhone. When it’s off, the toggle should be white.

To turn off Voice LTE:

  1. Go back to Settings.
  2. Tap Cellular.
  3. Select Cellular Data Options.
  4. Press Enable LTE.
  5. Tap Data Only. It’s should be off, as indicated by the blue check mark.

Reset Your iPhone’s Network Settings

Resetting your iPhone’s network settings will erase all the Cellular, Wi-Fi, Bluetooth, VPN, and APN settings on your iPhone. You’ll have to reconnect your Bluetooth devices and reenter your Wi-Fi passwords after completing this step.

  1. Navigate to Settings.
  2. Tap General.
  3. Select Reset.
  4. Tap Reset Networking Settings.

Put Your iPhone In DFU Mode

DFU Mode stands for Device Firmware Update, and it’s the deepest restore you can possibly do on your iPhone.

Before you go any further, make sure your information is backed up! A DFU restore will wipe your iPhone clean. So, if you want to save your photos and files, make sure they’re backed up somewhere.

Now you’re ready to now put your iPhone in DFU Mode. For detailed instructions, you can follow our guide here.

Contact Apple Or Your Wireless Carrier

If nothing seems to fix the problem, there may be an issue with your iPhone or your wireless carrier account. Visit Apple’s website to schedule a Genius Bar appointment or get phone and chat support.

If you think there’s an issue with your cell phone plan, contact your carrier’s customer support line:

  • AT&T: 1-(800)-331-0500
  • Sprint: 1-(888)-211-4727
  • T-Mobile: 1-(877)-746-0909
