I have been using paytm app since last year. Its the best app for online recharge and other payments. Thanks to Vijay Shekhar Sharma for fhis awesome production. It helps a lot by lessening the efforts of payments. We can pay or recharge from anywhere anytime. I am a non stop user of paytm. Paytm also offers online buying of various products lkke books, stationaries, electronics etc . at a very great discount. I have got my sennheiser earphone at just rs 700 after cashback and discount. I must say its a great app, please go for it
