Not only have I used up Telkom's slice of the internet, I have now used up Vodacom's too. According to Data Usage Pro I have used 284MB of the internet using cellular data on both my iPad and my iPhone out of a total of 500MB.
According to the sms I got this morning from Vodacom I have reached the limit.
Oh well, tomorrow is a new month and the internet will grow back overnight. Looks like an interesting test coming up. And an argument for sure. either with Vodacom or the app product rating box on iTunes.
