Just switched from to US Cellular from Verizon where I have been using Google Voice for several years. I am having problems getting it transferred over to my new phone even though my number has not changed. When I download the app, and go through the steps, it says my carrier does not allow for automatic configuring and to visit the HELP section on Google Voice. I've tried several different things and still nothing works. When I call my phone it says my voicemail is not set up. Help!
