Introducing Push to Talk 

When using compatible mobile phones, Push to Talk (PTT) allows you to talk with one, or all, members of a pre-defined group on the same network, much like using walkie-talkies.

Features and Benefits 

Push to Talk is a direct method for one-on-one or one-to-group communication. By pushing one button on the mobile phone, one-way communication can be made to an individual or a talk group over the GSM network using GPRS. Push to Talk is a great way to be in touch with one or more people instantly.

  • Direct speech connection is spontaneous and convenient.
  • Share information and experiences instantly, at any time.
  • Get and stay in touch with a group of people, whether they're pre-set, impromptu, or open chat groups.
  • View the availability status of group members directly on your phone.
