It’s easy. To start earning renewal credit simply log into your Mint account, and go to Refer A Friend in the left main menu where you will find your unique sharing link. Share it via email, Facebook post or through Facebook Messenger by clicking on the icon. You can also copy and paste your link and send to your friends through text or paper airplane–any other way you can think of! When your friends use your unique link to purchase a full plan on MintMobile.com and activate it you get your credit!
