The company will, however, begin the commercial roll-out of the service from March-April and the Sunday's soft launch will be only for Reliance Industries' employees.

Khan and musician A R Rahman will host the soft launch function of Reliance Jio Infocomm Ltd's (RJIL) 4G service on December 27.

The film star added that Reliance Jio deferred the launch twice because it was looking to improve the services.

RIL Chairman and Managing Director Mukesh Ambani in June had said that beta programme (trials) of Reliance Jio "will be upgraded into commercial operations around December of this (2015) year" and "financial year 2016-17 will be the first full year of commercial operations for Jio".

Later in October, RIL said financial year "2016-17 is projected to be the first year of commercial operations for RJIL".

Reliance Jio holds the highest amount of liberalised spectrum among telecom operators that can be used for deploying any technology for mobile services.

It has a total of 751.1 MHz spectrum across 800 MHz, 1,800 MHz and 2,300 MHz bands.

Khan was earlier the brand ambassador of Bharti Airtel. Telecom major Bharti Airtel's Founder and Chairman Sunil Bharti Mittal had recently said that RJIL was using Airtel's two icons, Khan and Rahman, for the soft launch.
