AT&T on Sunday will reduce the price of their 2 GB “Mobile Share Value” plan from $80 to $65 per month, with one smartphone and no annual contract. Two smartphones cost $90, down from $105.

The 2 GB plan includes unlimited talk and text, 50 GB of cloud storage using AT&T’s Locker service, and unlimited international messaging. AT&T (coverage map here) is directing customers who need more than two lines to its 10 GB Mobile Share Value plan, which starts at $145 for three phones.

AT&T already had a price edge over competitor Verizon, whose 2 GB More Everything plan costs $90 for one phone and $130 for two (unless you participate in Verizon’s “Edge” upgrade program, which makes you eligible for discounts). The news comes on the heels of T-Mobile’s recent improvements to its Simple Choice plan, which keeps prices pretty much where they are but increases data allowances. Sprint’s pushing their Framily Plan, which scales its savings depending on how many people sign up with you – at two lines, it’s $100 a month, with 1 GB of data for each phone.

A smartphone pricing move that benefits the consumer. Huzzah! Wonder if this will happen automatically or if I’m going to have to make a call to customer service (shudder) to get that discount.
