I need to get my S4 working on Metro PCS and I was wondering if anyone could guide me on that? I searched around but couldn't find much. I need to know exactly what settings to change to get it working and also if Metro's 4G will work with the bands available on the Verizon S4. I'm on ME7 at the moment, so I'm not sure if I have to update to 4.3 to make everything work okay. Any help is appreciated.
