Different data prices

<p>I have three contracts with Vodacom.</p> <p> </p> <p>To buy a top up data bundle on my main number will cost R149.00 for 1Gb. On my older contract, which is more than two years old, I have chosen not to upgrade, because I have paid off the ****le which I received with the contract, making my monthly bill less for the same amount of data. To buy 1Gb of data on this contract only costs R79.00?</p> <p>So, the data on the newer contract is more (a lot more) expensive..even though data prices should come down? I don’t understand the difference....data is data, doesn’t matter what device you use to make use of the data, no?</p> <p>Even if I choose to buy a monthly recurring bundle on my main number , it will be charged at the higher rate, so no benefit to buy a recurring monthly bundle compared to buying once off every month.</p> <p> </p> <p>It looks like a money making scheme to me...</p> <p> </p>
