How to add line with current phone, while transferring old number to new phone?


I am a current member. I want to get a new phone and transfer my current number to new phone. In addition, I also want to add a line using my old phone. What is be best way to do this? Thanks for any relevant comments!


first order the new phone and when it arrives activate as a replacement to your current line, then reactivate the old phone as a new line on the same account
