I want to use two GPRS Modems to transfer data , so I want to use bonding. as you all say about ethenet cards. so I wondering can I use bonding on two modems?

Yes, you can. It is separate package called "eql" and can
be found here:
/usr/src/linux-2.4/Documentation/networking/eql.txt
This is the introduction:
1. Introduction
Which is worse? A huge fee for a 56K leased line or two phone lines?
It's probably the former. If you find yourself craving more bandwidth,
and have a ISP that is flexible, it is now possible to bind modems
together to work as one point-to-point link to increase your
bandwidth. All without having to have a special black box on either
side.
The eql driver has only been tested with the Livingston PortMaster-2e
terminal server. I do not know if other terminal servers support load-
balancing, but I do know that the PortMaster does it, and does it
almost as well as the eql driver seems to do it (-- Unfortunately, in
my testing so far, the Livingston PortMaster 2e's load-balancing is a
good 1 to 2 KB/s slower than the test machine working with a 28.8 Kbps
and 14.4 Kbps connection. However, I am not sure that it really is
the PortMaster, or if it's Linux's TCP drivers. I'm told that Linux's
TCP implementation is pretty fast though.--)
I suggest to ISPs out there that it would probably be fair to charge
a load-balancing client 75% of the cost of the second line and 50% of
the cost of the third line etc...
Hey, we can all dream you know...
