SBI has a service Instapay, other banks also offer similar service, the one I know is HDFC bank. SBI Instapay can be used to pay utility bills as telephone, mobile, electricity and gas, recharge, insurance premium etc.

If you have an SBI debit card or net banking account, you can use Instapay service. There are very easy steps. And it is very useful if you do not want to open an account to pay your bills. Suppose you want to recharge your prepaid mobile card, you will have to open an account in one of the recharging service but with Instapay you do not need to open and account or login to service providers to recharge. Netbanking account is very useful for Instapay. If you have a debit card, you will have to follow some extra steps.
