Debian Lenny - NetworkManager 0.8.1 + Dell Wireless 5530 aka Ericsson F3507g

[M2 <M 2 btinternet com>]

Hi all,

I'm new to Debian (Lenny) and Linux all together so wanted to ask over here.

I have Dell Latitude D420 with Dell Wireless 5530 aka Ericsson F3507g
and all works perfect, well even better than XP and I am very happy,
but not to sure how to send /receive SMS when I use F3507g with Network 
Manager.

I have had few people telling me that they send me SMS, but when I 
swapped the SIM card
into my Mobile Phone nothing has been delivered and noting indicated 
incoming SMS in NetworkManager :(

Thanx in advance.
