Update your carrier settings on your iPhone or iPad

Learn about the carrier settings updates for your iPhone or iPad.

Carrier settings updates let your carrier provider update carrier network and related settings to improve cellular network connectivity and performance. Carrier settings updates can also add support for features like VoLTE or Wi-Fi Calling. For more information on carrier settings updates, contact your carrier.

When a carrier setting update is available, you'll be prompted to install it. If your carrier releases a mandatory update, you'll see an OK button instead of an Update button to let you know that the update was downloaded and installed.

You can manually check for and install a carrier settings update with these steps:

  1. Make sure your device is connected to a Wi-Fi or cellular network.
  2. Tap Settings > General > About. If an update is available, you'll see an option to update your carrier settings.

To see the version of carrier settings on your device, tap Settings > General > About and look next to Carrier. To see additional carrier information, tap the version number.

If you insert a new SIM card into your iPhone or iPad, you need to download the carrier settings for your new carrier.
