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 your network operator. Roaming
services may be more limited than for normal calls.
Before you can use the PTT service, you must define the required PTT service settings. See
