According to the developer, ”All active Subscribers can refer new friends or invite back previous Subscribers by using a simple referral link.” The referred friends receive the Jumpstart Bundle for faster leveling, while friends coaxed back to The Old Republic will get seven days of subscription access, one Complimentary Character Transfer for the lifetime of the account, and the Preferred Friends Bundle with special convenience and customization unlocks.
Finally, the player who referred the friend will get Cartel Coins, the Kurtob Alliance Speeder, and Battle Droid pets provided the friends become Subscribers within 14 days of joining.
Gamers can get the referral link here.
