Push to talk (PTT) over cellular is a two-way radio service available over
a GPRS cellular network (network service).
You can use PTT to have a conversation with one person or with a group
of people (channel) having compatible devices. While you are connected
to the PTT service, you can use the other functions of the phone.
To check availability and costs, and to subscribe to the service, contact
