Hello,
This device is not designed to operate in the South American region, thus coverage of supported bands might be smaller than the device intended for this market. So traveling with this device should not pose any issues, however, I'd recommend checking the laws of the countries you will be visiting to make sure radio equipment with external antennas can be brought in.
The supported bands of your device:
4G (LTE-FDD): B1, B3, B5, B7, B8, B20
4G (LTE-TDD): B40
3G: B1, B5, B8
2G: B3, B8
You can check the bands used by South American operators here.
Best regards,
