You can use push to talk 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
register
. The participants should confirm the reception of any communications
where appropriate as there is no other confirmation whether the recipient(s) have
heard the call.
To check availability and costs, and to subscribe to the service, contact your
network operator or service provider. Roaming services may be more limited than
for normal calls.
Before you can use the push to talk service, you must define the required push to
talk service settings.
While you are connected to the push to talk service, you can use the other
functions of the phone. The push to talk 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 push to
talk over cellular communications.
