AT&T Rolls Out Release Date For New Shared Data Plans

The “Mobile Share Plans“, which allow multiple users on the same plan to share data use packages between smartphones, tablets, and notebook computers, will be priced according to usage. They will start at $40 per month, plus $45 per smartphone, for 1GB of data, and will increase in price, up to $200 per month, plus $30 per smartphone for 20GB of data. Tablets may be added to the plan for $10 each, while laptops will cost $20 to add. Feature phones may also be added for $30 each, and all of the plans include unlimited voice and text messaging services. blogger, Brad Molen reports that a comparison between Verizon Communications Inc. (NYSE:VZ), and AT&T Inc. (NYSE:T) shows a remarkable similarity in rates vs service. The one major difference between the two companies, is that AT&T will offer up to 20GB of data usage, while Verizon sets the limit at 10GB.

With smartphones and tablets quickly taking over the world, it only seems wise that companies would offer a sharing plan, which allows for more data usage than before. AT&T Inc. (NYSE:T) realizes that tablets are here to stay, and they have adapted their marketing policy to adjust for this new source of revenue. It will be interesting to see how many of the smaller companies, such as T-Mobile will compete with these news share plans in the future.
