That is a great question, as we want you to fully understand how that will affect your bill before you move forward. Basically, a sub-account allow you to have two separate plans under one account. The benefits of a sub-account will allow you to have two different bills which may benefit you if you are using a line specifically for business. Now with that being said, having a sub-account will also raise what you are paying for the line you are wanting to split. When you create a sub-account that new account will have its own account level charge as well as its line level charge since it is technically under another account.
