The problem with state bank of india debit and credit card is that you cannot use them on international shopping sites so you cannot buy stuff from sites like amazon usa or ebay.com usa version which is not good.
Also you cannot open even paypal account with sbi card because they simply doesn’t accept them also other payment processor sites like nettle they also dont accept sbi cards which is really frustrating so dont go with sbi if you are frequent international stuff shopper.
