The LG Quantum Tethers Too–Here’s How

Turns out that the Focus isn’t the only Windows Phone that can tether, which yet again indicates that the OS can tether once MS creates a UI for it. Leigh dropped by and provided us the details:

Install (pretty sure its just the 4.9.7 drivers needed) ZUNE. If needed you may want to install the drivers separately:


Heard somewhere you have to turn off data connection….not so for me.

start with dialing ##634#
password 277634#*#
7.Engineer Menu
3.Port Setting
1.USB Switching
Phone will restart.
Connect to the PC and use dialer on LGE CDMA USB Modem with phone number *99#
**No extra init commands needed**

This is on a AT&T (unbranded) Unlocked Quantum shipped from US to United Kingdom, currently being used on Hutchinson 3G (
If extra init is needed it would be at+cgdcont=1,”IP”,”” I believe.

As you will know this is virtually identical to your Samsung process 😉

Also with these drivers I can get the C900B to register and connect with LG PC Suite ii, but once connected no further action possible. ie: cant open contacts/music/pictures etc

In the US we’ll revert to the AT&T settings:

On your PC you need to change the setting for the LGE USB modem. If you set it to prompt for user name you’ll be able to put in the login info. This is all it is for AT&T:
number: *99***1#
password: CINGULAR1

Thanks for the tip Leigh!
