Can't connect to 4g in Vietnam

[ironmonkey35]

Hi everyone,

I'm currently in vietnam working. I had a Sprint's Samsung S4 (unlocked); but since they don't have 4g here, i can't activate the 3g data plan. I tired to switch between networks but still no results. Can anyone help me?

You'll probably need to set your APN settings. I'm not running a TouchWiz ROM atm so I can't look and see how to do it for you, but I'm sure a Google search will help you out some. It's possible they may be running incompatible 3G frequencies.

Also, GOOOOOD MORNING!
