A:AnswerATT has a promo going on. That is who provides the credit not Best Buy. You can buy the phone at Best Buy and turn in your old phone to Att. Best Buy can tell u how much you will get. I got $350 credit for my I phone 7.
A:AnswerThat’s for the phone payment only. Service is additional depending on your plan. I bought a new phone through Best Buy and brought my old phone to trade in at AT&T for $700 credit spreads out through 30 months so it’s about $5-10/month for my phone payment only.
