On Monday, the nation’s second largest wireless network announced that it has developed an app that allows iPhone users to use their smartphones like walkie-talkies. The app marks the first time iPhones will get the feature in the U.S., the Associated Press notes.
By tapping a button in the app, users can transmit voice communication to groups of up to 250 users. So called push-to-talk systems are routinely used at construction, logistics and industrial worksites.
AT&T’s new app will only work for corporate customers who sign up for the service and will require additional support to implement.
A number of other phones feature push-to-talk service on networks operated by Sprint, Verizon (VZ) and AT&T.
Last year, Sprint announced that it would cease operation of its Nextel network — acquired during its disastrous 2005 merger with Nextel — by the end of June.
Shares of AT&T climbed more than 1% in Monday morning trading.
