Samsung Galaxy SHV-160k won't get signal
The SHV-160K is a version of the phone only made for the South Korean market. It works in the US, but only on GSM, not 3G or LTE, because the US cell networks use different frequencies to South Korea. (The Western half of S America uses the same frequencies as the US.)

This tells me that it should work as a 2G phone for you, but perhaps there's no GSM coverage where you are, only LTE? In that case, you're screwed and you should sell your phone to a Korean on eBay.
