... So me and my significant other are on ATT Share Plan (6GB data, $80 service + $25 iPhone5 + $25 iPhone5s = $130 a month) My contract ending tomorrow on my iPhone5, so I purchased FULL PRICE TMobile from apple.com. My partner has iPhone5s and contract will end October 2015. Lets say TMobile iPhone6 is unlocked (from apple.com website) and I am going to start using it with my current out of contract ATT service. When I split our service it is $65 a person. Doesn't this price have already included some part of $ amount for the iPhone5, I purchased subsides 2 yrs ago? Would that mean that I am pretty much getting ripped off because I paid full price for brand new iP6 and on top of that I am on plan which already is charging me for my previous iP5? Just trying find out whats the best option out there? Also, if I go with ATT GoPhone then I will be paying $60 for the most expensive option and thats only $5 less than our share plan.. But Not sure if GoPhone charge taxes on top of the $60? also how often do I have to renew it (every month or every time I am low on account)? any help welcome.. thank You!
