Sms (Text Messages); Requirements For Sending And Receiving Text Messages - Siemens GIGASET SL55 Manual

SMS (text messages)

SMS (text messages)
You can send and receive SMS text messages (Short Message Service) with your hand-
set. You can send a text message to any fixed network or mobile phone network
number. Your text message can be received as a text message by any device with SMS
functionality (mobile phone, PC, another telephone). If the recipient of your text mes-
sage does not have a phone with SMS functionality, then the message is played back.
You can write, edit, read, delete or forward SMS text messages from any registered
handset that has SMS functionality and to which the same receive MSN has been
assigned. When several handsets with the same receive MSN are in use at any one time,
only one handset can access the SMS functions.
Text messages are exchanged between SMS centres that are operated by service provid-
ers. The telephone number of the SMS centres through which you wish to send and
receive text messages must be entered in your phone (page 35). Up to ten SMS centres
can be entered. You can change the phone numbers of the SMS centres.
You can receive text messages via any of the SMS centres whose number you have
entered. Of course you must be registered to receive text messages with those SMS cen-
tres (page 36).
Your text message is sent through the SMS centre that is entered as the active send
service centre.
