Problem i see is data cost in SADC is not exactly the same. Mobile data costs in our neighbours are not the same and more likely what will hit your pocket.. they need ti simplify this to the point where you can simply buy data voucher for your roaming network which would make life more managable
My uncle is from Europe he visited South Africa. did a few calls when he arrived back in Europe he received a bill shocker oR40 thousand with Exchange. The networks should just charge R2 extra not charge exorbitant fees.
