Uber without Internet allows you to order Uber cab when you have no data (when you have no internet connection). It works without internet technology: application sends SMS to order Uber ride with no additional fee.
I love the idea 👊
Actually I found it quite absurd that a large majority of apps don't think about these kind of features upfront.
Even if places/countries without great Internet accesses are not your core market, when making a Mobile App you should always include SMS somewhere in the UX.
