I like the SMS notification idea, and will push it, but there are a number of systems in place. If subs don't know they can do a 'balance' to 100, they probably also won't know they should get a SMS.
It's all down to education.
If the first SMS ("your order has been received") was instant (within 30s-60s ... banks can do it for one-time password authentication) and it said to wait for the second SMS ("your order has now been processed") before using the bundle, there would be no education need.
