Problem Cause & solution
I cannot send or receive SMS
messages.
L You have not subscribed to the appropriate service.
Consult your service provider.
L The SMS message centre number(s) are not stored
or are incorrect. Store the correct numbers (page

L You may request that your service provider block
your phone number when making phone calls. In
order to send messages, you need to add “1832” to
the beginning of the Message Centre 1 number
(page 42). Note that by doing so, your phone
number will be sent along with your SMS
messages.

the message has been sent before using other
telephone functions.
L SMS message memory is full. Erase unnecessary
message in the receive and send lists (page 44,

ADSL service. We recommend connecting a filter
(contact your ADSL service provider) to the
telephone line between the base unit and the
telephone line socket.
