Sprint has had some success at retaining Nextel subscribers. LTE, which is available on the Galaxy S III, Skyrocket and Rugby Pro, offers faster connection times, lower latency and greater reliability, according to AT&T. It will soon be available for the Samsung Rugby III and Sonim XP5560 Bolt feature phones. It's available now for the Samsung Galaxy Rugby Pro, Galaxy S III and Galaxy S II Skyrocket, as well as the BlackBerry Curve 9360, BlackBerry Bold 9900, and Motorola ES400. PTT calls don't count against a subscriber's monthly data limits. The service costs US$5 per month when added to other voice and data plans, or $30 per month by itself.

The PTT software can be integrated with other mobile apps, such as fleet management, and in the future enterprises will be able to integrate their own applications with the system, according to AT&T. Enhanced PTT also allows for "supervisory override," where a manager can interrupt and talk over any current PTT calls in the group. Talk groups, which can be addressed all at once for general alerts, can be as big as 250 users. The software allows users to maintain contact lists of as many as 1,000 people. Among AT&T's selling points are that Enhanced PTT can run over its LTE network and can support larger contact lists and talk groups than competing systems do.
