Consumers across the country can avail Reliance Jio's services from today, as the company opens its doors to all potential users having any 4G-enabled handset in an aggressive quest to garner 100 million subscribers.

According to sources, the Jio SIM -- which so far was available only at Reliance Digital stores -- will now also be offered through multi-brand outlets and mobile phone shops.

"The SIMs will be available at nearly two lakh stores across the country, including locations where SIMs from other vendors are also sold," sources said.

A major beneficiary of the offer would be users of devices like iPhone, Xiaomi, Motorola and Lenovo who were not a part of the preview offer so far. RJio, which had already roped in 1.5 million users in the test phase, is gunning for 100 million users at the shortest possible time.

Nearly 20 brands including Sony, Sansui, Videocon, LG, Samsung, Micromax, Panasonic, Asus, TCL, Alcatel, HTC, Intex, Vivo, Gionee, Karbonn and Lava were part of the preview offer which provided free 90-day unlimited calls and high-speed mobile broadband trials to 4G smartphone users of these brands.

The offer is now being rebranded as a 'welcome offer', which from September 5 will provide unlimited services till up to December 31, after which users have been promised voice calls -- both local and STD -- as well as roaming free of cost, for life.
