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 "PTT settings," p. 86 and "Configuration settings," p. 87.
