You can send and receive SMS text messages (Short Message Service) with your hand-

set. You can send an SMS to any fixed network or mobile phone network number. Your 

SMS can be received as a text message by any device with SMS functionality (mobile 

phone, PC, another telephone). If the recipient of your SMS does not have a phone with 

SMS functionality, then the SMS 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 27). Up to ten SMS centres 

can be entered. The SMS Service Centre "Anny Way" and the provider's SMS service 

are preconfigured at the factory. You can change the telephone 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 29). 
Your text message is sent through the SMS centre that is entered as the active send 

service centre. 

◆ Calling Line Identification may not be permanently deactivated for the MSN used 

◆ You must be registered with your service provider to receive text messages 

◆ The handset must have Unrestricted authorisation to send an SMS. To receive an 

SMS, Incoming only authorisation is adequate. This setting can only be made with 

an S1, SL1 Komfort handset or on the SX303isdn, SX353isdn, CX203isdn, 

CX253isdn base telephone

◆ You must not allow the network provider to block the phone numbers you have 

entered for the SMS centres.

In Germany, the SMS service is available exclusively to telephone numbers that are con-

nected with the local area network via Deutsche Telekom AG (you receive your tele-

phone bill from Deutsche Telekom). It is currently not possible to send a text message if 

you have a call-by-call connection. 
If the telephone of a receiver cannot receive an SMS in the fixed network, the SMS is 

automatically read as a voice message. Between 7.00 and 22.00 hrs, these text mes-

sages are delivered immediately in the form of a telephone call. Text messages sent 

after 22.00 hrs are stored and delivered the next day.
