We do get questions about what SGX5150 series (notice the US, ES and JS suffixes) cellular gateway I need based on country.
These are cellular gateways and subject to carrier connections and the country for use is called out in the part number suffix. Models are only for use in their respective regions. Part numbers ending in U/US for US/ Canada, E/ES for European Union and J/JS for Japan. For other countries, user should confirm channel compatibility. SGX 5150 has not been certified in all countries.
This information is listed on the last page of the user guide .
