Hello Regdawryter,

Activate your iPhone or iPad

You need to connect to a Wi-Fi network or a cellular network to activate and continue setting up your device. 

Tap the Wi-Fi network that you want to use or, if available, tap Continue Without Wi-Fi to use your device's cellular network. If you're setting up an iPhone or iPad (Wi-Fi + Cellular), you might need to insert your iPhone SIM card or iPad SIM card first. You might also be asked to activate your eSIM.

Get help if you can't connect to Wi-Fi or if you can't activate your iPhone.

If you're experiencing issues with activating the device, this page will provide some further assistance and steps to try: If you can't activate your iPhone or iPad (Wi-Fi + Cellular) - Apple Support

Follow these steps 

1. Restart your iPhone or iPad.

2. If you're using a cellular-data connection, connect to a reliable Wi-Fi network instead.

3. If you get an error message on your iPhone or iPad that says the activation server is temporarily unavailable or cannot be reached when trying to activate, wait a few minutes, then repeat the previous steps.

If you still can't activate your iPhone or iPad, try again using your computer instead:

1. Make sure that you have the latest version of macOS or the latest version of iTunes.

2. Check that your computer has an internet connection.

3. With the cable that came with your iPhone or iPad, connect your iPhone or iPad to your computer. Locate your device on your computer.

4. Wait while your computer detects and activates your iPhone or iPad: 

If an alert appears that says "Set up as New" or "Restore from Backup," it means your iPhone or iPad is activated.

If you get an error message on your computer that says that the SIM card isn't compatible or is invalid, contact your carrier.

If you get an error message that says the "activation information was invalid" or "activation information could not be obtained from the device," use recovery mode to restore your iPhone or iPad.

If you still can't activate your iPhone or iPad, contact Apple Support.

If you continue to experience issues after trying the above steps you may try reaching out to your mobile carrier for further guidance.

Cheers.
