You'll pay $0.00 for your phone and put the rest ($227.59) on your Tab.
Pay a $10 monthly Tab charge for 22 months plus $7 to make your Tab balance zero, and then you'll only pay your monthly plan charge.
Plans start from $28/month
That plans start at $28 concerns me (LG G4)
And thinking of equivalent that's 13 + 10 a month more, coming to 536 dollars spent over the two years. You'd be better off just buying a phone yourself for less than that if you would rather keep your current plan.
