I've got two iPhone 5 smartphones and one non-smart phone on a legacy AT&T family plan with 700 shared minutes, unlimited texts and unlimited data. Generally we are using less than 2GB data each per month, and never use up our allotment of minutes. We are paying $156/mo (and this includes a $10 discount thru my wife's employer). We want to upgrade to 2 iPhone 6s models and keep the existing non-smartphone on the plan (for a non technical relative). In SoCal we generally only see about 3 bars of LTE. Frankly I think network performance sucks. I would expect the same on Verizon here given the population of users but their network will work much better for us when out of state and have no access to wifi. But our data usage will skyrocket there. The question is whether we just stay on our existing plan and upgrade our iPhones or enroll in the Apple upgrade program and switch to Verizon. I'm having a very hard time finding an accurate monthly cost estimate. It appears that regardless you now spread the phone cost over 24 months instead of shelling out $300 up front as in the past? Is that true? Would it better to talk to someone at an Apple Store or a Verizon store and can you only enroll in the iPhone upgrade program at an Apple Store?
