Hey Could you tell me how do I establish connection through a USB GPRS modem? I'm using Slax distro (based on Slackware) with KDE; Enlightenment and GNOME environments are also available, so suggest any working method you know - I'll get needed utils and libs. My modem is already connected, kernel module is loaded, what I need is just to connect to my ISP. If you know there are some easy2use programs (or scripts) for this, please post their names here. Thanks in advance

I think scanModem looks for usb modems as well... not sure. But:GPRS is not dialup - ... from: http://turtiainen.dna.fi/GPRS-HOWTO

There are plenty of gprs howto's on the net... google is your friend.

... and so on.

Read around for your phone and distro.

Thank you very much

Yes, confusion!!! GPRS? Do you mean by mobile phone (cell phone)? If so, forget it!
If it is a standard USB modem then wvdial will (should) detect it.
"My modem is already connected" - to what?
I think you need to rewrite your original question.

How can this statement be justified in the light of: http://turtiainen.dna.fi/GPRS-HOWTO and the other examples of working gprs connections all over the internet?

Simon, it's a question of practicality. Mobile phones just aren't designed to be used as computer modems. The vast majority only provide data backup through the so-called modem. The few (VERY few) that do actually work are so slow that users would be very disappointed with the performance. An added problem is that mobile phone companies can hardly be termed good ISP's in general, at least in my part of the world.
Perhaps this will change in future, but presently, that is the state as I see it.
A notable exception to this is the CDMA system, which generally uses fixed terminals rather than mobile phones. This is what I am using just now.

I'll agree that mobile phones do not make good modems. However, a poor modem is better than no modem at all, and gprs phones, when working, are often better than landline dialup.

Recently, there seems to have been a "rash" of sales of these gprs enabled phones in Pakistan. Many people seem to be interested in using them for internet browsing from their PC. Especially as vendors are promising broadband-like speeds.

To a user previously languishing on a dialup connection over an old (copper) landline: gprs will look like a gift from the gods.

Of course: GNUlancer (OP) is Russian

Background:
I have visited Lahore (ages ago) and even tried to learn a little urdu - salaam meri Urdu kharab hei. <cringe>

I was interested in the burgeoning hacker community (as well as the normal tourist stuff). While I was there, the only reliable communication I had was through the internet cafes.

Thanks Simon. Your urdu is probably as good as mine. I'm British - just keeping the Empire alive here in Pakistan for the last 22 years!
Pakistan is very advanced in mobile phone usage, 1 in 3 of the population has one! However, internet connectivity via these phones isn't widespread. CDMA systems are much more common and provide excellent service compared with other dial-ups.
Russia is also advanced in CDMA and I would really recommend GNUlancer to take this option.

Cool - me too: ain't it amazing how us Brits keep bumping into each other?
