If you are an Axis Bank customer, here is how you can recharge your prepaid mobile. You can either recharge by visiting any Axis bank ATM or do so by sitting at your home if you have an Axis Bank Internet banking account.
Login to your Net Banking account (iConnect) and find the Mobile Banking link on the left menu as shown in the picture. When you click that option, you’ll be present with 4 choices, Recharge mobile, Register mobile number, View registered mobile and check status. 
If this is the first time that you are using Axis bank net banking for Mobile recharge, you should ‘Register mobile number’ first. Click on that option and fill out the details such as Nickname, Mobile number, Operator and then submit.
You will then be required to validate those details, and to do that you should enter your login id and transaction id (this is different from login password) and also another password depending on your NetSecure setup (See Axis bank 2FA security).
Once you enter everything, your mobile is now registered and you can click on Recharge Mobile option to recharge your prepaid mobile.
Note that not all recharge values will be available, for example in Airtel Network, you’ll only have options like Rs.100, Rs.200, Rs.333, Rs.444, Rs.1000 and Rs.99 (lifetime prepaid) which are noticeably talk time top ups only.
Similarly, you can recharge your friends or relatives mobile by registering their mobile number.
