I have used many wallet like- Paytm, Freecharge, Oxygen etc. But I feel Paytm is a best & safe wallet to use. I used only Paytm Wallet to Transfer money instead of giving my bank details. I do work online on various websites. So, At the Payment Time, It is very risky to give my Bank details to various merchant. Thats why, I use Paytm wallet to transfer that money to my Paytm Account and From Paytm Account to my Bank Account.
There are also many Offers run by Paytm time to time. This is the one more reason to use Paytm wallet . They offers various Recharge and Bill Payment Offers. Thats why I always used Paytm to recharge of my Mobile no.
