UTStarcom PPC-6700 / XV-6700 / HTC Apache

I have the 6700 now and can connect to the via wifi, but every time i try to go onto internet explorer, it tries to dial into (#777) the verizon network. Now i need the network to be open for pix/flix messaging, i just have the pay as you go plan, but is there a way to make it so it uses the wifi to connect to the internet?? please help i dont want to spend $30/month for internet i wont use that much. thank you...
