I am using Phone Pe from last 1 year and find it very useful and easy to use app. Phone Pe is far better than other existing similar apps like Paytm, Airtel Payments Bank, BHIM UPI and Tez.
Phone Pe allows the user to link his bank account through UPI for transactions with ease. Unlike Paytm, BHIM & Tez it returns the failed transactions money rapidly.
Most of the times the transactions are successful whereas BHIM, Tez & Paytm fail the transactions and also include OTP problems.
Unlike Paytm and other wallets, Phone Pe gives cashback on 90% of the transactions of every type.
Note: Mobikwik & JioMoney are the worst wallet apps.
