I don't see any Latin American countries on the Digi LTE-M/NB-IoT certification list.
If the country you intend to use this modem for is relax on both regulatory and carrier certifications, I suppose you can try as long as the country has either CAT-M1 or NB-IoT coverage, and has the frequency bands that the modem can support. You can check the CAT-M1 and NB-IoT coverage from GSMA web site:
The current Digi XBee3 LTE CAT-1 modems are either AT&T certified or Verizon certified, and both products are reaching End Of Life (EOL) because the underlying Telit cellular modules are reaching EOL. There is no CAT-1 alternative from Digi at _this_ moment.
