Guys, just want to confirm one thing. Regarding GPS and AGPS.

So from what I understand, GPS is using 3 or more satellites to triangulate our location and it cost close to none. Free. But for AGPS, some data are being transfer from and to our telco server. So, there are some charges.

Currently I'm using postpaid so can confirm myself. So, those who use prepaid, it is true GPS is free and AGPS is costly? For an hour of AGPS, how much is the charge?

I'm really concern about this because last time, I get my phone bill with RM30 of internet usage, which I'm not remember when actually I used it. So, hopefully AGPS doesn't cost much.
