How can I send and receive faxes in Ubuntu using a GSM Network?

Which hardware would you suggest? Which fax client? Would this work easily or is it complicated?

You will need a GSM module and some PBX program, like Asterisk to do that (you can also create a PBX software using module's API). Take a look at this: http://www.voip-info.org/wiki/view/GSM and find for "GSM PCI-Express Module" on google. Im sure you will find something on Pika Technologies or Khomp.

I was also wondering about this; I just need to send fax from Linux via bluetooth phone, though - not receive them. So I thought I'd jot down my notes.

Turns out, there's a program /usr/bin/fax - in Ubuntu, it's installed via sudo apt-get install efax (which is kinda inconvenient for online searches, as "eFax" is also the name of a well-know commercial service website... (and "fax" in itself is bound to get you many poor search results)).

I finally found this thread that seem to talk about exactly this thing, though; and here it is:

sending faxes with t610 - gmane.comp.kde.devel.bluetooth / mailinglist for development of KDE utilities for bluetooth

Actually you can use

 rfcomm bind /dev/frcomm0 <phone-bluetooth-address> 
to bind the bluetooth device to /dev/rfcomm0. You can then use this device as a modem, e.g sending AT commands etc.
...
A[s] I have a prepaid card, I can not send facsimiles, so consider this also, wheter your provider allows you to send fax papers ;-) ...

Hehe, I also had a long conversation with the hotline of my operator just a minute ago. For some reason I had to dial the fax number without international prefix (+49..).
...
Well, this is my result - still problems with permissions, but it works. efax also complained a lot about some non-existing lock file at first and I had to create some strange directories first.

$ sudo /usr/bin/fax NAME='fred' DEV=rfcomm0 PAGE=a4 FROM='' send

efax: 18:13 sent -> /tmp/kde-fred/kdeprint_mRL9Bbit.002
efax: 18:13 done, returning 0 (success) 

But the quality of faxes really sucks badly. I still prefer a pdf via email ;)

So, apparently it can be done from the command line - but only if your mobile operator has that service for your subscription, I guess...
