My family plan with AT&T increased by $25 a month by signing up for the 2 year contract after buying the 6 plus. That is just my part of the increase of a 3 party plan. That is an increase of $300 per year because they determined I don't qualify for the $25 per month with my iphone5. Just thought I would let members know. Apple or AT&T did not make that increase clear before I signed the 2 year contract. JFYI.
