3 network dialup settings

Hello I am connecting to the internet through an old vodafone pcmcia 3g data card
with my 3 network sim card in windows xp, so the vodafone card is apparenly not locked. The problem is it
only connects for seconds or minutes before it quits receiving though it does not appear to disconnect on its status page. It is definitely connecting as I can check emails and download a at least one wikipedia page. It also does NOT disconnect in the middle of a download. I just downloaded a 11mb and 3 mb download and both completed before it dropped off. Those are the only times it stays connected for 5 minutes or more.
I have adjusted all the following configuration options in every combination:

Maximum speed (though the initial popup always says I am connecting at 384kbps
Enable flow control
Enable modem error control
Enable modem compression
Enable LCP extensions
Enable software compression
Negotiate multi-link connections
turned on or off or adjusted fifo buffer settings (?)
there must be a way?
Thanks

here is modem log

I guess I sort of solved my conundrum. I installed a program called BySoft StayAlivePro.
It sends a packet (?) every second to 10 different websites. It seems to be working.
My connection is staying alive but it is eating my money as I pay per mb. I wonder if there is not a better way. When I connected through my phone by bluetooth with the very same connection details I did not have this problem, meaning I never lost my connection, so I suppose the problem is with my vodafone modem. The phone died so after hours of searching at the library in town I found an old driver for the vodafone card as vodafone no longer supports this card. My connecton still craps out but not as often.
