6. Select Your Device Type

Select your device type, then follow the prompts to complete the device enrollmentWhen you've completed adding a device, you can repeat the process for as many devices as you wish.

We recommend adding your office landline, your home landline, tablets, and additional cell phones you use for work or phone - basically, the more backup devices, the better!
