Manually update carrier settings on your iPhone or iPad
Carrier settings updates let your carrier provider updated carrier network and 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 see a prompt to install it. Installation takes less than one minute, and you can keep using your device. If your carrier releases a mandatory update, you'll see an OK button instead of an Update button to let you know that the system downloaded and installed the update.
If you dismiss the installation notification, you can manually update carrier settings:
Make sure that you connect your device to Wi-Fi or a cellular network.
Open the Settings app.
Tap General.
Tap 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:
Open the Settings app.
Tap General.
Tap About. The version number appears next to Carrier.
Tap the version number to see additional carrier information.
To verify that you have the latest carrier settings installed, contact your carrier.
