There's still a couple questions I have regarding the whole thing:
- I don't think you can sign up for a Next plan currently without buying a new phone on the plan first. Maybe I'm just missing it... but I already have a phone that I'm happy with, and I wouldn't mind going to a non-contract service. They say I'm eligible but I'm being forced to add a phone to my cart to start with. I just want the plan.
If you just want to switch to the new 10GB Value Plan, you need to call, chat or visit a store. They can switch you. From some more reading I've done on it, It doesn't look like they null your contract. They do flag you as eligible for an AT&T Next plan though.
It used to be that you had to wait until you were upgrade eligible before beginning a Next plan. Then, only a few weeks ago, they changed it to six months in to your current contract. Now, they're letting you move to the new share plan as long as you had a contract renewal before Feb 2nd and make you Next eligible.
Also, you don't HAVE to do a AT&T Next plan when you go to upgrade your phone. You could sign a traditional two-year agreement and, at that time, your monthly line fee will simply go up to $40/mo instead of $15/mo. So you could use this as a temporary discount.
-Can I pay an optional deposit on the phone to lessen the monthly payments? I'm so used to paying 100-200 up front for a phone that I'd be willing to do that still if I that money gets taken out of the monthly fee. Currently it looks like your only options are pay 100% up front or pay 0% up front without anything in between.
Yes, you can make an additional payment for the phone when you purchase it if you like. You're probably better off doing that at a physical store. You could also simply do the Next plan, then call in to customer service and pay an additional balance towards your device. Unsure if doing it afterwards will make the monthly payment drop, however.
-Can I pay off the balance of the phone at any time? Say I find a good deal on another phone outside of ATT (used or otherwise). So I pay for my new phone in full on craigslist or something. Can I then sell my old phone myself and use that money to pay off the rest of my old phone at once?
Yes, you can pay it off anytime. You can make payments for 12 months, pay it off, then get a new phone on the AT&T Next plan and sell off the device if you think you can get more for it.
My math on that would be:
iPhone 5S 32GB, initial upfront is $52 (tax). Then, 37.50/mo for 12 months. So, by the time you've traded it in, you've paid $502 of the $801 total. If you sold it on the second hand market, I wouldn't expect to get more than $400 for it, $350 would probably be an easy sell.
So you'd be paying it off with an extra $300, to turn around and make MAYBE $50-75 on it. I don't think it would be worth the effort for me. But, if you have another use for it, like putting it on a family members line or something, that could be worthwhile.
