What is happy roam?

Starhub and m1 now competing to offer prepaid user roam data like at home. Personally i like this very much save the hassle of swapping sim or registering a new line when at overseas. I am now contemplating to cancel my hotlink in 2016 and use either m1 or starhub to roam. 

Starhub is slightly more x but i allow you to data roam in 6 countries.... australia, taiwan, thailand, indon, hk, msia

Even now singtel prepaid can data roam.

In general 10 sgd is for 1gb for 30 days or 15 sgd for 2gb

Alternative can be buying local sim 

Hotlink and u mobile provide option to data roam for rm 10 per day. The supporting country is the only differentiator
