At first I used this website to do only the recharge only they are giving many recharge offer to us daily, I like this web design site so much nw they have upgraded it while login through the paytm now they are asking OTP - one time password it is secure to do recharge.
To speak about paytm it is really a super web site I have never seen like this web site I am using this website from past five years it is really super I have PURCHASED many product from this site it is worth for money,
