If it is a GSM unlocked phone it will work here.
And if the bands match with the bands that use your phone will work 3G and LTE in the local company that you get your sim card. If you give me brand and model of your phone I can check where will work better.
Its the LG Tribute, model LGLS676
Thanks Riva
VIVA and Claro 2G use 1900. This from your info. His phone has GSM 1900 so it will work with Claro on 2g. It definitely will work if unlocked. I have used phones similar here already.
