KT launches smartphone walkie-talkie service

KT, South Korea’s second-largest telecom company, has launched a smartphone radio communication service that works on wireless mobile networks.

The new service, “olleh Walkie-Talkie,” allows subscribers to use one-on-one or multiple radio communication through a Wi-Fi network or the long-term evolution networks.

“We have launched the olleh Walkie-Talkie as a new communication method which can be useful in daily lives,” KT’s marketing division vice president, Kim Hak-joon, said Sunday. “The new service will suggest a new paradigm of communication after voice calling and text messaging.”

With the new service, users can utilize their long-term evolution (LTE) smartphone as a push-to-talk walkie-talkie on the Internet protocol. A maximum of 20 people can talk with each other using the service, KT said.

“The olleh Walkie-Talkie is expected to be handy for enterprise customers who want a real-time multilateral communication method and those who frequently do outdoor activities or hobbies,” the company said.

The service has a high-quality communication mode that enhances voice quality even where Wi-Fi connections are not stable by supplementing them with the LTE network.

Users can download the olleh Walkie-Talkie application from app stores such as Google Play free and open a chat room to start a conversation. For those who want to use it while moving or doing activities, the service also supports Bluetooth devices such as headsets.

The service now supports only Google’s Android mobile operating system version 4.4 or higher. A new version for Apple iOS devices such as iPhones will be updated soon, KT said.

The company said the service also is for those who use SK Telecom or LG Uplus.
