On Monday, AT&T revealed in an announcement that it has expanded its shared data services to offer larger shared data plans which will chiefly be aimed at the business users as well as data-guzzling consumers.

After offering bandwidth in blocks that range from between 1GB to 20GB, for $40 to $200 per month, while introducing its group data plans last summer, AT&T has now announced that it will offer data plans for up to as much as 50GB data per month.

In its Monday announcement, AT&T said that, from March 22 onwards, it will offer 30GB, 40GB, and 50GB data plans - including unlimited talk and text, and tethering capability - which will respectively be priced at $300, $400, and $500 per month; with an additional charge of $30 per smartphone.

The announcement implies that, over and above offering the more data advantage per account, the new larger shared data plans can also be split among more devices. While the 20GB tier has been limited at 10 web-connected gadgets, the higher capacity plans of 30GB, 40GB and 50GB extend the cap to 15, 20 and 25 devices respectively, for business users. However, for consumers, the limit will still be 10 devices.

For businesses which require data sharing for more than 25 devices, AT&T will also offer the benefit of the new `Business Pooled Nation for Data Plans' that allow users to add basic phones for $20 per month with
300MB of usage.
