I already pulled the plug on Vodacom on our local business GPRS application due to unreliablility, and now goodbye to Vodacom for our roaming. It's very shortsighted for whatever network to charge like this - they get the money ONCE, and then never ever again, never, for all time, and I will tell thousands of business and personal aquaintances over the next years about how greedy they (Vodacom/AIS whoever) are.
