My service provider (T-Mobile Germany) allows me to buy data packages which can be used one time and independently from the montly data plan.
I.E. I buy a 500MB package and from that moment on, my data usage will be deducted from this package. Once it's used up, my normal plan comes into effect again.
These extra packages do not extend my original plan, but replace it as long as they are not used up.
In addition, there is also the possibility to book an unlimited flatrate for 24 hours. During this 24 hours the used volume will not be counted.
Could this be somehow implemented in the software?
