Reliance Jio MNP: How to Port Your Number and Get Jio SIM Card

Here's how you can use MNP to shift to Reliance Jio without changing
your number:

First up, you need to send a text message to your current operator requesting
for a port out. The message PORT should be sent to 1900. In return, you will
receive a Unique Porting Code  from1901 with 15 days validity from your
current carrier.

Head to any Reliance Mobile Store or retailer and fill up the Customer
Application Form (CAF) where you'll also fill in the porting code. Submit the
required documents (proof of address, proof  of identity and photograph)
, and in return Reliance will issue a new Reliance Jio SIM card. Once
activated, this SIM will use the same phone number you already had
and your old SIM will be deactivated.
