I'm a boostmobile customer but what I'm seeing is that a lot of customers brought this unlocked phone and they are having activation problems. They are saying they brought it straight from samsung and I want to do the same thing, but I use my phone for work and can not deal with problems like that.
Save your money man , I've had every galaxy since the S5 and this is the worst one. I've never felt so let down and swindled by samsung before. Do your self a favor and buy a different phone.
