GSM has much more to offer than voice telephony. Additional services allow you greater flexibility in where and when you use your phone. You should contact your local GSM network operator for information on the specific services available to you.
A brief outline of GSM Services is below.
Call waiting & Call hold
If you are using the phone, Call Waiting will alert you to a second caller. You need never miss an incoming call.
Use Call Hold to put the person you are talking to on hold so you can call another party, and then switch between the two calls.
Call forwarding
Use Call forwarding to divert incoming calls to another number.
Calling line identity (CLI)
CLI displays the number (name if stored on your phone) of the incoming call.
SMS (short messaging service)
SMS (text messaging) allow you to send & receive text messages on your phone. Services available from many of the world's GSM networks today - in addition to simple user generated text message services - include news, sport, financial, language and location based services, as well as many early examples of mobile commerce such as stocks and share prices, mobile banking facilities and leisure booking services. (More information about SMS can be found in GSM Technology.)
Data Services
Using your GSM phone to receive and send data is the essential
building block leading to widespread mobile Internet access
and mobile data transfer. GSM currently has a data transfer
rate of 9.6k. New developments that will push up data transfer
rates for GSM users are HSCSD
(high speed circuit switched data) and GPRS
(general packet radio service) are now available.
