I have MF 626 modem and Telecom prepay XT mobile plan. My hard disk has a dual boot of Vista and Ubuntu 9.10. When I use Ubuntu, the Telecom Connection Manager interface is automatically mounted, but it does not work (Ubuntu cannot load any files from it), and it also overrides Ubuntu Network Manager, which also now does not work.
When I eject the Telecom Connection Manager from Ubuntu desktop, the Ubuntu Network Manager starts to work, recognises the modem and I can connect to the internet through it.

Unfortunately, the connection only actually works occasionally; sometimes I can browse, but mostly not (regardless that the Network Manager shows connection being ok).
This is not a coverage problem, because if I switch to Vista I can easily connect. I can even connect from Ubuntu 9.10 liveCD with that very same Ubuntu Network Manager, but not the hard disk installed Ubuntu 9.10!

Is it that when the The Telecom Connection Manager mounts it affects the working of the Ubuntu Network Manager stopping it from working properly with the modem, even when the The Telecom Connection Manager itself has been ejected?

Is there a way to:
a) get The Telecom Connection Manager work with Ubuntu,

b) stop the automatic installation of the The Telecom Connection Manager in Ubuntu when the modem is mounted, or

c) whatever magic that would enable the Ubuntu Network Manager to function correctly?

I like Ubuntu and have spent a lot of time trying to get this to work and your help and comments will be greatly appreciated.

Thank you.

Ubuntu has had a stormy ride with mobile broadband in the 9.10 issue; 

I found that wvdial worked well for me: I have had quick and reliable connections;

if you look at my posts in December time,

I found mandriva worked well, as did ubuntu (using wvdial)

I was trying this evening to get a Vodafone 3565-Z going on mandriva; (this too is a ZTE modem, like the MF626 and MF636 that Telecom use;) not succeeding so far; I find this same modem works very well on fedora 12, using network manager!

Thank you cokemaster and pdc for your advice.

I will need to digest them for a bit.
The info seems to be meant for disengaging the modem autodetect function from the Windows OP, while what I am looking to do is to keep the autodetect in the Windows side but disengage it from the Ubuntu OS side, so I would need to modify the instructions accordingly (fingers crossed).
The wvdial option might be safer for a computer novice like me.

wvdial would work well; turning off the modem is likely not the answer to get the connection; happy to be told I am wrong; 

for anyone wanting to try it though, the pdf file does note

"After entering the AT command AT+ZCDRUN=8, the self-installation or auto-run
features has been disabled, to re-enable this feature, input AT command

so     AT+ZCDRUN=8 turns off
and  AT+ZCDRUN=9 turns it on again 

as cited here also

Peter Curtis is very knowledgable about usb modems
