The Anil Ambani-led firm will bundle 300 minutes of app-to-app talking, valid for 30 days at Re 1, translating into 10 minutes usage per day under the limited period offer. Users will get a daily data credit of 7 MB into their accounts that can be used to make these calls, Reliance Communications CEO Consumer Business Gurdeep Singh told reporters here.

These apps will include the likes of WhatsApp, FB Messenger, Skype, Google Hangout, imo and Viber. RCom, which has 110 million subscribers, however, did not disclose the number of 4G users. RCom's 4G LTE network operates in the 850 MHz spectrum band. Operators in the country, including the likes of Airtel and Vodafone, have been pushing their 4G services launching offers like data credit and cheaper tariffs.
