I recently bought a Samsung galaxy s4 at a refurbished phone place that's for verizon. I'm currently using T-mobile but the people told me that the phone was an unlocked verizon phone. So how do you make it so you can use the phone without having to use global? I would like to use CDMA/LTE/EVDO which is what I kinda need. I was able to use use global for calling but data wouldn't work. If I use global for calling and texting while not using roaming would that make my bill higher?
Added (1). Do I have to download the T-Mobile apps for everything to work? If so how to I download them?
