We've bought a Sony Vaio PCG-4121EM supposed to have a built-in 3G modem. It has a SIM-card slot at its bottom. We've inserted a newly-bought SIM-card but nothing happened and the modem is still not visible among the computer devices (neither in Windows device manager nor in "Modems" Control Panel applet). How to turn it on?

I would usually seek to turn a built-in device in the BIOS setup, but there seem to be no BIOS setup on this Vaio - Windows 7 splash screen appears immediately as I turn the computer on.
