From tomorrow, AT&T will cut the price of its 2GB data plan tier ‘Mobile Share Value’ from $55 to $40. In total, this plan will cost you $65 per month in data charges for one device, comprised of the reduced $40 data plan and a $25 device charge. As usual, there is a $25 charge for each device that shares the data allowance. For one device, this represents an overall reduction of approximately 20% of AT&T’s current offerings. Otherwise, the plans remain the same with unlimited talk and text service, unlimited international messaging in addition to the shared data.
