I'm the cofounder of wifi dabba. It's fairly simple why people use our service and we're able to run profitably. 3G/4G is too damned expensive for the average Indian. It's fine for the middle class in our country, but for the vast majority of the population, mobile data eats into their daily expenses rather heavily.
What is the range of the wifi? Will I be asked to stand around bakery and tea shop to use it or it is available everywhere at all time? Already data rates are being slashed in big way in India by Jio. We can use 4G internet at the price of Rs.10 per day. They may slash further also. They can deliver the same service anywhere or everywhere straight to the smartphone without relying on other shops around. Your website do not have clarity on range and speed u support.
