i activated my sim and used port option. Then when i wanted to add money t-mobile wouldn't accept my debit card... it gave me an error saying that i have to set up auto payment in order to continue. I don't really like auto payment.. so i closed the window. Now i'd like to fill that $30 unlimited data plan and i have no idea how to fill! I wanna buy redeem card but when i enter my phone number it saying This is not a valid T-Mobile phone number. Please re-enter your phone number. What to do?
