I was wondering about this to! I am getting next this yea so this comes into play next year.
once you trade the phone it they put a credit or something on your account and you just use next right?
What is the order? can you upgrade before trading in or do you have to trade in before you upgrade again?
To bad you can't use next to upgrade and they give you 30 days to trade in your old phone.
per ATT
AT&T Next Trade-In
Any time after 12 or 18 monthly installments (depending on your AT&T Next agreement), you may upgrade to a new smartphone!
As long as your current smartphone is in fully functional and good physical and working condition, you are eligible to trade it in. Or, you can choose to pay the remaining monthly installments and keep your current smartphone.
How to complete an AT&T Next upgrade1
Step 1: Select a new smartphone
Choose another AT&T Next installment plan and go to Step 2. Or, upgrade to a traditional 2-year contract*, or upgrade by purchasing a phone with no annual contract at regular price.
Step 2: Make the trade
Your trade in* must be in good physical condition and fully functional and with the Activation Lock disabled.
If the trade in is not in this condition, you smartphone is ineligible for trade-in for an AT&T Next trade-in, and you are responsible for the remainder of your installment payments.
The remaining installment payments will be billed to your account upon receipt of a trade in that is ineligible.
Tip: If you have Mobile Insurance, you may file a claim and pay the deductible for a replacement smartphone Then use your replacement smartphone as your AT&T Next Upgrade trade-in.
Step 3: Complete Upgrade
When we receive your qualified trade-in, your upgrade and the terms of your previous AT&T Next agreement will be completed. No further installments are billed for the trade-in.
How to trade in your phone via mail
