No matter how you frame it, we now have to pay more for our iPhones, yes? I've been on AT&T since day one and ready to purchase my 5th iPhone since 2007. I'm struggling to wrap my brain around the argument that we aren't paying any different than before.
That depends. Personally paying less compared to before.
We're on the Mobile Share 10GB plan (doubled to 20GB) with 4 iPhone lines (@$15ea) and 1 iPad line (@$10) for $170/mo. Taxes and fees are much lower compared to the old minutes-based plans as the $100 for base 10GB is considered internet access and therefore not subject to all the taxes and excise fees (which seemed to be around 15-20% of my phone bill).
The new plans are also much better for those who get cheaper phones. In the old model, AT&T provided greater subsidies for iPhones compared to other phones. The repayment of that subsidy is hidden in the mandatory data plan. Someone who was getting, say, a Moto G that's free on contract (but costs AT&T less than $200 in subsidy) was effectively subsidizing iPhone customers.
Just as an example:
Example 1: Family Talk (assuming you can get activation/upgrade fees waived)
$70 700 minutes inclusive of lines 1&2
$20 line 3&4 fee (@$10ea)
$30 shared unlimited messaging
$120 data (@$30 ea)
Plan: $240/mo or $5,760 for 2 years
Device: $1,200 upfront cost (32GB model @$300ea)
Total 2-year cost: $6,960
Example 2: Mobile Share Value
$100 10GB
$60 line 1-4 fee (@$15ea)
Plan: $160/mo or $3,840 for 2 years
Device: $3,000 paid either in full or 0% APR installment plan (32GB model @$750ea)
Total 2-year cost: $6,840
Seems like a small difference. However, the first example penalizes people who don't upgrade on a 2-year schedule. Meanwhile, if you go 4 years without replacing your phone, the second example saves you a lot of money. Here are the calculations if only two lines upgraded every two years and the other two of the lines just kept their phone for the entire 4 years (e.g. my parents)
Example 1: Family Talk
Plan: $240/mo or $11,520 for 4 years
Device: $1,800 upfront cost (32GB model @$300ea, 6 devices total)
Total 4-year cost: $13,320
Example 2: Mobile Share
Plan: $160/mo or $7,680 for 4 years
Device: $4,500 paid either in full or 0% APR installment plan (32GB model @$750ea)
Total 4-year cost: $12,180
