I think the NEXT plan is a rip off
Currently my wife and I are sharing the 10gb plan for $130 a month before taxes. Everyone knows that is $100 for the data and $15 for each line. If you go with the old method of paying, say $199 for a 16gb 6, then you are paying $40 a month for the 6's line. So it would be $100 for the data, $15 for my wife's line and $40 for my line, which makes our bill $155 a month before taxes.
If I get the 6 through NEXT we will still have the $100 for data, $15 for each line, plus the $27.05 a month for the phone, making our bill $157.05 before taxes and that is the for the cheapest phone. Unless I am missing something with NEXT it does not seem like that great of an option.
You fail math. If you do standard upgrade: $199 + $40 +$600 = $839 for a $749 phone. You can not upgrade after year one either. With next, you just pay $749 for the phone spread out over 20 or 24 payments, no interest or fees. Your bill does not change and you can pay off next whenever you like or not and upgrade after 1 year if you choose next 12.
I guess you're right, Next is a bad option
