Network-dependent features
SMS and EMS messaging
The T610/T612 is capable of sending and receiving SMS
and EMS messages, and linked messages.
With the Short Message Service, a user can send
text messages containing up to 160 characters to
and from GSM mobile stations
With the linked SMS, the user can link up to 10
SMS messages together to create a longer mes-
sage (network-dependent service)
A Service Centre (SC) acts as a storage and forwarding
centre. The T610/T612 also supports using SMS as a
bearer type for connecting to WAP.
SMS consists of two basic services:
Mobile Originated SMS
Mobile Terminated SMS
For Mobile Originated SMS, an SMS message is sent
from a Mobile Station to the SMS-C where it is
forwarded to its destination. This can be another Mobile
Station, or a terminal in the fixed network.
A Mobile Terminated SMS is when an SMS message is
forwarded from the SMS-C to a Mobile Station. When
the Mobile Station receives the message, it returns a
delivery report saying the transfer was successful.
Fixed dialling and Restricted calls
For a company or an organization, it can be useful to
restrict phone calls. Fixed Dialling allows the user to
preset a number of digits, for example area codes. This
restricts the user to making calls only to numbers which
use the preset digits as leading digits. Fixed Dialling
makes use of the PIN2, and it requires fixed dial fields on
the SIM card.
The Restrict Calls service allows the user to block
outgoing or incoming calls in certain situations, for
example international calls.
SIM application toolkit
The SIM Application Toolkit (SIM AT) is a smart card-
centric method of deploying programs that apply only to
GSM and to SMS and USSD transports. Programs must
be distributed on smart cards. For an operator, a company
or service provider, SIM AT offers a powerful way to
deploy programs and services to users, without the need
for new or upgraded equipment. All necessary setup and
programming is distributed to users over the air, directly
to their phones. In the T610/612, a separate menu is
available for functions residing on the SIM card. These
can include submenus for controlling functions, and also
functions which allow the phone to initiate calls, send
data, and display information to the user.
