Network-dependent features

SMS and EMS messaging

The Z300 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 pre- set 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. 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.
