Pantech Breeze II 3G Phone Issue

[DRC72]

I bought this phone back in February for my parents to use. Now up until a couple of weeks ago it was picking up a 3G signal without any issues, but all of sudden now it just stays on GSM/EDGE. Now I know it's not the network, because my iPhone stays on 3G most of the time. Plus I have a micro-cell that I use at home and the Pantech will not pick up a 3G signal from it anymore where my iPhone clearly has no issues getting 3G from it. Plus the Pantech number is listed in my micro-cell account. Could my parents have activated a secret menu by accident disabling 3G? I find it odd that it won't pick up 3G anymore, when there clearly is a 3G signal present. Customer service was no help on this issue. any ideas? It's a very odd situation.
