I'm using my W910i as a modem, by connecting it to my pc and sync it with the pc suite, and I bought a pass for a 5 days unlimited web and walk, but when I use a 3G connection it disconnets me in about 30secs. so how do I ge the 3G connetion to work for a long time like 3-4 hours straight and not disconnet me in 30 sec. or does the 3G even comes with web and walk. thanks in advance
