Instead of setting up a whole new account, you can transfer your existing service to your new home. It's a lot easier and quicker option than setting up everything from scratch.
You don't have to put down a new deposit, commit a new billing date to memory, set up another My Account profile, re-enroll in AutoPay or recreate most anything you already happily have in place. Plus, it's a great time to make any changes to your service that you've been meaning to do but haven't gotten around to. Also, you can ask what new specials, promotions or bundle discounts are available.
