For Chile, you will want to check coverage maps depending on where you plan to go. Claro may not cover many areas outside of urban areas and Entel is the sole provider for Easter Island. Movistar in general has the widest coverage but their customer service is lacking, actually the three majors can equally be bad depending.
For Chile, the 2G and 3G bands are 850 and 1900 MHz.
