RJio had signed a pact with Chinese firm Huawei for sourcing various 4G devices.
"Reliance Jio and Huawei have signed an agreement for 4G devices which includes smartphones, tablets and mifi dongles. It has signed agreement with couple of other Chinese device maker as well," an industry source said.
The shipments dates are yet to be confirmed, he said, adding that there are two other Chinese firms in advanced talks to supply 4G devices.
Last week, RJio had said that it is "actively working with all major handset device manufacturers to ensure and certify their phones for use on Jio network and shall ensure adequate availability of phones in entire price range".
As per the licensing agreement, August 31, 2015 is the deadline for all companies which won BWA spectrum in 2010, including RJio, to roll out the services in at least 90 per cent of the service areas, failing which the Department of Telecom will have the right to withdraw the radiowaves.
