11 Push to talk
Push to talk over cellular (PTT) is a two-way radio service available over a GSM/GPRS
cellular network. PTT provides direct voice communication connected with the push of
the PTT key.
You can use PTT to have a conversation with one person or with a group of people having
compatible devices. When your call is connected, the person or group you are calling does
not have to answer the phone. Besides the GPRS counters, the phone registers only one-to-
one calls in the recent call lists in Call log. The participants should confirm the reception of
any communications where appropriate as there is no other confirmation whether the
recipients have heard the call.
To check availability and costs, and to subscribe to the service, contact your network
operator or service provider. Note that 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.
While you are connected to the PTT service, you can use the other functions of the phone.
The PTT over cellular service is not connected to traditional voice communication, and
therefore many of the services available for traditional voice calls (for example, voice
mailbox) are not available for PTT over cellular communications.

in the start screen.
