Ahead of the impending launch of Reliance Jio's 4G services, telecom operator Reliance Communications on Tuesday announced app-to-app 4G calling at Re 1.

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.
