Hi,
Im not an IT savvy, this Q might be silly to those of u, but i just want to get a clear pic how it work.

How to ensure "consistent" speed up to 20mbps to all plan (as mention in thier website)?

When I look on the 'compare rates'..YES is the best among others in term of speed.
So it very tempting to get it.
The only thing is price for device......very expensive woo..
