Tmobile Add A Line - What about be the most. I currently have two lines, but am wanting to add a 3rd for my daughter. I believe i can get her a new iphone se for half off, or $200. What is the best way to add that line? For two lines, youโll pay $130 monthly. Compare the monthly costs and features of essentials, magenta, and magenta max plans.

I currently have a plan of 4 lines on magentamax, with insider discount and a free line in place. But, i am thinking to port another line to this current plan. What about be the most.
