They do a credit check when you initially sign up for the account not when you upgrade the devices.
Thx. I just got my bank to upgrade one of my accounts last week from $5K at 15% to $10K at 11% with rewards, and I don't want another credit check for a while since I just bought a new car in August as well.
After doing the math I think that AT&T NEXT may not be best for us. My AT&T store was recommending that I go back to the Apple Store before it's too late Friday, and see if they will refund and then re-ring up our iPhone 6 and 6+ on the NEXT plan, since my son and I like to upgrade every year.
Because we have 5 phones upgraded at different times, we get 3 upgrades one year and 2 the next year, then it repeats with 3 the next year and 2 the year after that, etc. However, my wife and daughters only like to upgrade every 2-3 years, or they take our 1-yr old phones when we're done with them. They don't care.
So, usually my son and I will use 2 of our upgrades every year, and when we pass down last year's phone we sell the oldest deactivated phones to help pay for the new ones. That helps defray the upgrade cost, and nobody has a phone older than 2 years.
The Math:
Right now we have 5 phones and 5 iPads & pay $160 for 15GB, $30 x 5 phones, $10 x 5 iPads =
$360/mo not counting the cost of the phones that we buy outright (we spend about $2600 over a 2 year period after Applecare and taxes on 5 phones, which would amortize out to $108/mo if we didn't pay them off, or $41/mo for just 2 phones).
With our 2 iPhone 6's on NEXT we'd pay $130 for 30GB, $15 x 2 NEXT phones, $40 x 3 old phones, $10 x 5 iPads, and $42.50 x 2 for the new iPhone's cost =
$415 total including the cost of the phones. But
with all 5 of us on the NEXT Plan we'd be paying $467.50/mo to AT&T, which is almost the same cost over a 2 year period with us paying for our phones outright on our current plan.
Except that with NEXT, after we add in the additional $700 cost of taxes and Applecare+ for all 5 phones, the NEXT plan actually costs us more over a 2 year period; although everyone would have a 1 year old phone instead of some of us going for 2 years, and we'd get 30GB when we only need 10-15GB.
I understand that with NEXT we can choose to not upgrade after just one year, and the monthly charge stays at $15 when the phone is paid off in 20 months, and we then own the phone and don't have to trade it in.
Decisions, decisions...
