Text Messages (SMS)
The Short Message Service (SMS) allows you to send and
receive text messages consisting of up to 160 characters.
A useful feature in your phone is that you can send text
messages to a group which you have defined in your phone
book. See “Groups” on page 36. Instead of calling or send-
ing a text message to the members of that group one at a
time, you can simply send a single group SMS.
If your SIM card does not contain the phone number to
your network service centre, you must specify the number
yourself. Otherwise you cannot reply to received messages
or send your own messages. See “Enable the Phone to
Send SMS” below.
Note! The Short Message Service may not be available on
all networks. Some network operators may only allow
SMS to be sent within their own network.

If you want to send or reply to a message, you need to make
sure that your network operator’s Service centre number is
set. Most modern SIM cards already contain this informa-
tion at the time of purchase. You can obtain the service cen-
tre number from your network operator.
