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
list in Call log. The participants should confirm the reception of any communi-
cations where appropriate as there is no other confirmation whether the reci-
pient(s) 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 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.
10.3.6 E-Mails
You can use your mobile phone to send and receive e-mails. Information on
the availability and conditions of using the e-mail service can be obtained from
your network operator or service provider.
10.4 Access codes
• Security code
The security code (5 to 10 digits) protects your phone against unauthorized
use. The pre-set code is 12345. Change the code, and keep the new code
confidential and in a safe place separate from your phone. You can set
whether the phone requests the code. If you key in an incorrect security
code five times in succession, the phone ignores further entries of the code.
Wait for 5 minutes and key in the code again.
• PIN and PIN2 codes (4 to 8 digits), module PIN, and signing PIN
The personal identification number (PIN) code protects your SIM card against
unauthorized use. The PIN code is usually supplied with the SIM card.
Set the phone to request the PIN code each time the phone is switched on.
The PIN2 code may be supplied with the SIM card and is required to access
some functions.
