As a part of the Free Welcome Offer, to port in to Jio , you need to send the following text message – PORT followed by your 10-digit mobile number to TRAI’s central number for mobile number portability – 1900.
Download the ‘MyJio’ app from Google’s PlayStore (since the SIM can as of now be activated only from a selected list of Android-based mobile handsets) and generate an offer code through the app.
Walk in to any Preferred Jio , Reliance Digital Xpress, Reliance Digital Xpress mini, or prominent multi-brand Jio stores with the port out code and your Free Welcome Offer code along with your mobile handset.
You would also need to submit a copy of any of your identity and address proofs viz. Voter Id Card, Passport, Aadhaar Card along with a couple of passport-sized photographs for obtaining your Jio SIM card.
