Have to admit, when this new plan was announced it looked like a good deal. Here's my situation:
"Unlimited" data, 700 minutes, unlimited texting
2 lines: $150/month.
iPhone cost: subsidized @ $300 each, 2-year contract
Total 2-year cost (not including resale value of iPhones):
$150x24 + $300x2 = $4200
When I saw the 2-line 10GB unlimited talk & text plan for $130/mo, at first I thought, "wow, $20/mo savings - I'd be ok with going from "unlimited" to 10GB shared + hotspot capability."
Then I read this epic post:
I never looked into AT&T Next because I knew it was just a way to hide the cost of upgrading - and I never plan on upgrading more frequently than every 2 years, so I thought the BYOD plan would be a money-saving strategy. But:
10 GB shared data, unlimited minutes, unlimited texting
2-lines: $130/month.
iPhone cost: full retail @ $750 each
Total 2-year cost (not including resale value of iPhones):
$130x24 + $750x2 = $4620
Ignoring the AT&T next options, switching my plan from the $150/mo plan to the $130 plan would cost me ($4620-$4200)/24 = $17.50/mo more.
That $20/month plan "savings" evaporates when not using AT&T's traditional subsidized iPhone pricing.
So my bottom line? By switching to the 2-line $130/mo plan, I'd:

Suck it, AT&T.

this is a big up-front obfuscation of the details..
The existing mobile share plans with a two year contract are still cheaper for most people. This is why AT&T is pushing these new plans. Marketing through obfuscation.

So my bottom line? By switching to the 2-line $130/mo plan, I'd:
- Throw down $1500 every other year for new phones
- Go from "unlimited" data to 10GB/month
- "Save" $480 in plan cost over two years
- Pay that savings right back ($420) by buying iPhones at full retail.
- Net monthly savings ($4620-$4200 /24) over 2 years: $2.50
Suck it, AT&T.
