Well, I normally use my mobile phone as a modem to connect to Internet.
My phone is a LG GX500 (dual SIM). I have all of its drivers already installed on my Windows XP computer. When I connect the USB cable, it shows a virtual CD with installers, that are already installed on my computer. Then it automatically ejects that virtual media and "becomes" in a modem, with certain serial port (COM) associated. Then I use a program called LG Internet Kit as a dial-up connection dialer, configured to my SIM1 card and do I get connected. It is the normal way I follow everyday to connect to Internet...
Now, I would like to know more, to try something different. Yesterday, I plugged a Bluetooth USB device in my laptop after some recurrent bug of LG GX500 (when the battery charge reaches full state, a pop-up appears on phone suggesting to disconnect the cable for energy saver purposes, and so it buggy disconnects the PC from Internet - if I unplug and plug again the USB cable and reconnect, the the same warning pops up in a few minutes, because the battery is full, and the PC is disconnected again). So I tried to use LG Internet Kit and it asked me to point to another COM port. I used the COM port of my Bluetooth device and it functioned: I was using the Bluetooth stick intead of the USB cable.
But today I tried again, with no success (I removed the related devices in Device Manager, deleted knows Bluetooth devices...).
1) What am I doing wrong?
2) Are there any software to do it better?
3) Can I do it with any mobile phone that supports Bluetooth connection to PC, even that it does not have EDGE/GPRS/WAP support?
