would this work in namibia?

Ok, so I checked the map and the roaming availability online but there is no mention of Namibia but I know that people from Namibia use their cellphones here by way of roaming on our networks.
So, I was wondering if I can use my Vodacom 3g modem there (in Namibia) by way of roaming on one of their cellphone networks?
