Head down to Starhub roashow happening at J8 this week from 7 to 13 Oct and receive a free 12-month 1GB local bundled data when you sign up and purchase a Samsung Galaxy Note 3 at the event. Only black and white color is available and Galaxy Gear is sold separately.
From our research the difference in prices and subscription plans are not significant between the telcos in Singapore unless you are going for the premium plans (M1 offers the best premium plans) so we suggest that you should purchase your Galaxy Note 3 from your existing telco.
