When a network provider settings update is available, you'll be prompted to install it. Installation will take less than 1 minute, and you can keep using your device normally. If your network provider releases a mandatory update, you'll see an OK button instead of an Update button to let you know that the update has been downloaded and installed.
If you dismiss the installation notification, you can update network provider settings manually by following these steps:
- Make sure your device is connected to Wi-Fi or a mobile network.
- Tap Settings > General > About.
- Follow the onscreen instructions to install your network provider update.
If you set up a new eSIM or insert a new SIM card into your iPhone or iPad, you may need to download the network provider settings for your new network provider.
To see the version of network provider settings installed on your device, tap Settings > General > About and look next to Network Provider. To see additional network provider information, tap the version number. To verify that you have the latest network provider settings installed, contact your network provider.
