Hi Yu Hong ! You can visit www.motorist.sg/rewards then scroll to the bottom of the page to learn how to earn mPoints.
Refer Friends & Earn mPoints:
In the app, swipe the carousel banner until you reach the last slide (Refer a Friend). Click on that and you will be able to share your referral link to your friends. If your friends sign up and register their vehicle(s) in the Motorist App, you'll earn 10mPoints through that. :)
