I've got 3 lines on my account. 1 (mine) is a smartphone and the 2 others are dumb phones. My line and one of the dumb phone lines are eligible for an upgrade right now and I'd like to take advantage of the upgrade and use it on my (smartphone) line.
I've been told there is a way to use the upgrade from the other line (not transferring the upgrade) and get myself a new phone without losing my unlimited data or paying full price for the phone.
Can someone please explain to me in detail what I need to do to achieve this. I want to use the upgrade but don't want to lose my unlimited.
Thanks in advance
