■ Push to talk
Push to talk over cellular (PTT) is a two-way radio service available over a 
GSM/GPRS cellular network (network service). Push to talk provides 
direct voice communication connected with the push of the PTT key.
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.
