AT&T Inc. plans to push a new push-to-talk wireless service with visits to 27 cities, including Kansas City, as millions of legacy Sprint Nextel push-to-talk customers look for new phones.

Kansas City’s turn comes Oct. 25, when the 5½ hour event rolls into town with a continental breakfast, working lunch and prize drawings, according to AT&T’s online registration page.

AT&T’s offer comes as millions of Sprint customers with legacy push-to-talk phones are looking for a new home. Their devices run on the Nextel network that Sprint plans to shut down next summer.

Sprint is heavily promoting its new Direct Connect push-to-talk phones that run on its Sprint network.

AT&T, the second largest wireless carrier, already has a push-to-talk offer. The promotion is for its Enhanced Push to Talk service it plans to launch late this year.
