Unleashing another round of price war in telecom space, Tata Docomo today slashed its international call rates by whopping 83 per cent to one paisa per second on calls from Punjab to the US and Canada. The new offer will allow its prepaid subscribers in Punjab to pay any call made to the US and Canada at one paisa per second instead of current tariff of six paisa per second. “We have rolled out this new ISD pack in Punjab keeping in mind that most of people from here live in the US and Canada and this new tariff will allow their near and dear ones the convenience of affordable calling to these countries,” company’s chief operating officer, Mr Aditya Gupta, said on Tuesday.
