@megaglobal South Africa is a country itself. I believe you need to select specific country to buy roaming...
Which country in central Africa you're going to?
I am traveling to Cameroon, Central Africa. Please advise. Thank you.
@megaglobal I check their roaming page, I can see many African countries but no Cameroon. Safe to say there's no roaming in Cameroon I guess. I think it's better to buy the local sim there.
