Porting out of family plan


    I am currently on a family plan and will soon be leaving T-Mobile to join another provider. I've read other threads and am aware that I will need to do a "Transfer account or line ownership" with the account holder. However, will I need to stay with T-Mobile for an additional month before I port out? I've also read that T-Mobile doesn't pro-rate for cancellations. If I do, I am thinking about doing just Unlimited Text and Talk for that month although I am an avid data user. It's just seems like it's the most cost efficient option for me. I'm hoping someone can tell me I'm wrong! TIA for your help.
