It will work. Just verify the bands on the phone to the country you are going to.
Forget CDMA and Verizon. It is now an LTE network and will be shutting down most of the older technology at the end of the year.
It won't be good for you. I would get a phone with wifi calling if you have internet. Hopefully they add some coverage in your area.Will 3G still work as I don't get LTE only 3G is available in my home or will my phone be useless.
