It seems that Singtel's HSDPA or 3.5G network doesn't work in e mrt.
I used to surf using my K750i but this was limited to GPRS speeds.
Lately I got a Treo 500v which supports UMTS to replace e K750i as using GPRS was simply too slow. After a couple of days of use, it seems that whenever e train goes into e tunnel after bishan station, e network indicator would switch from 3G to G. This meant that e 3G connection was lost.
I wonder if it's my phone or that 3G is not supported underground?
