AT&T announced this afternoon that, starting today, both new and existing subscribers are eligible for a $100 bill credit when activating a new line of service with a smartphone on Next—AT&T's upgrade program that allows customers to get new devices on installment plans.
More specifically, the Next program allows qualifying customers to get a new mobile device for $0 down, without upgrade or activation fees, and no annual contract. The cost of the equipment is spread over a two-year term, which makes this $100 promo somewhat appealing.
