The mobile operators here offer a number of unlimited data for a day bundles free of charge with many tariffs, where you activate such bundle and for the following 24 hours you have unlimited data usage. During this period what you download is not counted against yout remaining data.
There is number of ways how to implement a feature covering this scenario, but as I think most users have a way to check, how much data remaining they really have with their mobile operator, I would suggest a feature, where the user can just manually edit the remaining data amount shownt for current period, not affecting his overall period limit settings. This way, such feature would cover any other causes, where the shown remaining data amount gets out of sync with the reality for current period. Without being familiar with the app code, I think in general such a feature should require relatively small change to the code.
