I would like to switch providers. I have 3 lines of service (including myself). Is it possible for me to remain financially responsible for the account even though I dont have a line of service for me personally?
Yes. If you port out your line, puck a new line to be the primary, and set up new user name and password. I believe the PIN code can stay the same.
It saddens me to hear that you want to leave our family. As your advocate, I want to make sure that your question is answered correctly. If the account is under your name, you will still be responsible for the account as far as balance and monthly payments go. If you are not the account owner, you can request a transfer of service to move any remaining lines into your own account under your name. Does this answer your question?
