Network-dependent features
SMS and EMS messaging
The J200 is capable of sending and receiving SMS,
EMS messages and concatenated messages.
• With the Short Message Service, a user can
send text messages containing up to 160 char-
acters to and from GSM mobile stations.
• With the linked SMS, the user can link several
SMS messages together to create a longer
message (network-dependent service).
A Service Centre (SC) acts as a a storage and for-
warding centre.
SMS consists of two basic services:
• Mobile Originated SMS (from a mobile station to
an SMS-C).
• Mobile Terminated SMS (from an SMS-C to a
mobile station).
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 mes-
sage is forwarded from the SMS-C to a Mobile Sta-
tion.
Fixed dialling and Restricted calls
For a company or an organization, it can be useful
to restrict phone calls. Fixed Dialling allows you to
preset a number of digits, for example area codes.
This restricts the user to making calls only to num-
bers 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. Check
with your operator about this feature. The Restrict Calls service allows you to block outgoing or
incoming calls in certain situations, for example
international calls.
