Bought this for a long trip to SA. Needn't have bothered though. You can get the same thing in just about any supermarket for 50p or less. Previous reviewer was right in that you have to activate it in a Vodacom store. He didn't say that they won't be happy to do it, since you didn't buy the SIM from them! I managed to persuade the folks at Jo'burg airport, but I think that was because I looked pathetic and worn out after a long flight. ANyway the SIM worked, was easy to top up at any supermarket, though an option to do it over the phone would have been good.
