launch2net is your software of choice to connect your Macintosh to the internet using your mobile phone or PC data card as a modem. launch2net supports many mobile phones and most PC data cards and already includes all connection settings for most mobile network operators worldwide. So there is no need to enter cryptic data like APNs, GPRS parameters or modemscripts any more.
Finally you can forget about searching for the right Mac OS X drivers for your mobile phone or PC data card. No more explaining what a Macintosh is to overstressed support hotlines and no more long internet sessions looking for the right answer.
This demoversion allows you to connect 10 times for 5 minutes each. You can still connect afterwards to buy the full version online or to register the software.
