Their are many-e wallet such as oxigen wallet, mobikwik, etc amomg which I choose paytm. Paytm is very trustworthy, easy to use and very quick. Paytm also provides promocodes for recharging, shopping, and other bill payments like electricity, insurance, etc.
Now a days even shopkeepers and taxi drivers also accepts paytm cash. Paytm cash is more safe than carring cash, even we donot have changes we can use paytm cash. Shopping through paytm gives us cashback varying from product to product can also be used for recharging.
