I've had my two series three watches now a year since December. I've signed up for the 3months free watch deal and just before the three months is over, cancelled. I've always ended up signing for another 3 month trial a month or two later and then cancelled again just before the three months is over. I'm about to sign up again and it again is giving me the free three month trial. I've never paid for a single month of the watch plan and yet it keeps offering me the trial every time I sign up. T-Mobiles site has some bugs because it clearly says one trial per watch purchased. This will make about the fourth trial I've had.
