Hey there hope2022__,

Thanks for reaching out to Apple Support Communities. We're happy to provide some assistance.

Did the message that you see indicating you need to update mention a cellular update? If so, take a look here on how to perform a cellular update:

Manually update your carrier settings on your iPhone or iPad - Apple Support

If you dismiss the installation notification, you can manually update carrier settings by following these steps:

1. Make sure that your device is connected to Wi-Fi or a cellular network.

2. Tap Settings > General > About.

3. Follow the onscreen instructions to install your carrier update.

Keep us posted.

Have a great day!
