Okay guys. An update as i'm in singapore now using singtel. Using the unlimited 3 days pass for SGD18. Forgot to ask the CS when buying is it really unlimited or got quota, which i think got. Oh well.

Here's my speedtest using e5756 mifi :-



It's ok considering this is peak time (9.30pm).

Edit : Added another speedtest done at 12am/1am :-





Quite similar even on non peak time. Maybe the speeds are capped?

Weird though as i'm only getting a grade D. Maybe it's for singapore as i think that most users here use fiber broadband 100mbps lol. Also evident as the speedtest shows that i'm slower than 70% 

Could be. I think that singtel caps the speed though but it's pretty consistent throughout the whole day. Here's another speedtest at 7pm :-



It's always around the same speed.

There are good options in Malaysia such as u mobile which gives you around 10-20+mbps dl for prepaid and maxis (prepaid) also can give around the same with the modem i'm using. So i think that Malaysia's mobile broadband does give better speeds, even for prepaid. However, singtel singapore does seem more consistent, even though the speeds are lower.
