I cannot find any information on The BRN404X for use in South Africa

I need to know if the Boron LTE-M will work in South Africa? Do I need your global sim to work or will it work with our local sim provider? i.e MTN , Vodacom 3g 4g and LTE.

I want to build the following project which uses Boron for push notifications.

The Boron LTE (BRN404X, BRN404, and BRN402) cannot be used in South Africa. They can only be used in the United States, Canada, and Mexico at this time.
