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 new features like 5G or Wi-Fi Calling.
When a carrier settings update is available, you'll be prompted to install it. Installation takes less than one minute, and you can keep using your device normally. 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.
If you dismiss the installation notification, you can manually update carrier settings by following these steps:
Make sure that your device is connected to Wi-Fi or a cellular network.
Tap Settings > General > About.
Follow the onscreen instructions to install your carrier update.
If you set up a new eSIM or insert a new SIM card into your iPhone or iPad, you might need to download the carrier settings for your new carrier.
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. To verify that you have the latest carrier settings installed, contact your carrier.
