46 Sending and Receiving Text Messages (SMS)
Sending and Receiving
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 T28 is that you can send text messages to a group
which you have defined in your phone book. See “Groups” on page 33.
Instead of calling or sending 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 information at the time of purchase. You can obtain the
service centre number from your network operator.
