I also thinking the same. If you go to the biggest bank website. It is very simple process indeed. Just Give passport number and another information That's It.Banking in South Africa is absolutely horrible. The fees are very high, compliance is almost as bad (as in incompetent and clueless) as JohnnyDoe thinks, and products and services in general are of low quality.
Non-resident banking in South Africa is not common. Maybe for citizens, but every South African I've met who has managed to leave South Africa doesn't want to continue banking in South Africa.
You can apply online and FIll up the form that's it.
I want to know why it is not worth ??
Why It is not popular as many othere?
