How to activate a new iPhone when old one is broken?

Hi pnkdds,

Thank you for posting in the Apple Support Communities. We understand you are having some problems activating your new iPhone.

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

Tap the Wi-Fi network that you want to use or select a different option. If you're setting up an iPhone or iPad (Wi-Fi + Cellular), you might need to insert your SIM card first.

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

You'll find additional steps here: Set up your iPhone, iPad, or iPod touch

You'll follow these steps, If you can't activate your iPhone

Also, if you are attempting to sign in using your Apple ID, you'll learn your options for obtaining a verification code, here: Get a verification code and sign in with two-factor authentication

Cheers!
