AT&T slices $15 off of its 2GB Mobile Share Value plan
For those wearing two-year handcuffs, the per smartphone price is $40 (meaning the new rate for 2GB of data for each smartphone would be $40 + $40 for a total of $80). Those without a contract such as AT&T Next subscribers, and customers bringing their own phone, pay only $25 per line.
There is a caveat. If you have a two-year pact and want to upgrade to a new phone when able to do so, you will either lose the discount, be forced to switch to AT&T Next or pay the full retail price for the new handset. Up to ten smartphones can be on one plan, and the new pricing begins on Sunday.
