I have resolved my problem. I used the MFG app to change the APN, but the thing that gave me trouble was the carrier provided me with the wrong APN settings. After entering the correct APN setting it was like the flood gates opened and my phone came alive with several alerts!
I've switch to a new carrier and they do not support my LG Quantum. The phone and text works perfectly, but I was told I need to change the APN settings in order to get the 3G to work. I've searched, but unable to find how to change my APN.
