How do I erase my phone if it’s off?

Remove the device from Find My, as was requested.

You can’t erase a damaged device, or a device offline, battery depleted, or out of communications.

Your data is protected by your passcode in the unlikely event that the device is repaired, and is not then erased.

Verizon said just remove the device from find my phone on the iCloud but does that erase the content on the phone?

No

But, if you can't get at the data on the phone, no one else can either. Even if someone could somehow get at the data.....(they can't).....they would have to guess your passcode correctly in a very limited number of tries.

Hi,

do you have another device that you can use? If so, go to the find my app -> devices -> the device you want to erase-> and click erase.

if you do not have another device, you are going to need to use a computer at a library, or ask a friend, and go to iCloud.com. Log in with your credentials, press the apps button (looks like a 4 by 3 grid) and press find my. Locate the device you want to erase, click on it, and press erase. Whenever it is booted up again, and connected to the internet, it will be erased.

You missed this part......The phone is broken.

It cannot be erased using Find My or a computer or any other means.

You just told us that you can't erase the device using iCloud or any other means. Follow the instructions from Verizon.

Once again......Follow the instructions from Verizon.
