For sure, but you need to actively do some stuff. This was one of the complaints we got, that it's a manual process to manage your data bundles on pre-paid.
Most people obviously do it as it's better than any kind of bill-shock but we now pretty much made it automated. This is great for example where you give your kid a fixed monthly 'data allowance'.
To be quite honest, I'm a bit surprised about all the negativity in this thread. Top Up Data was built to address the issues YOU guys had with the current system. (
non-real-time billing on contract, etc.)
But you don't need to use it, no one is holding a gun against your head. As Lancelot have pointed out a few times, it seems whatever is done, there will always be a certain bunch complaining. The mind boggles....
