Poor 3G coverage maps

I was searching around the Internet when I saw some crowd sourcing at work. Apparently, someone has created poor 3G coverage maps for the 3 Singapore telcos. Looking just purely at the maps, it seems that Singtel has the worse coverage. However, do not take it as the whole truth as there are many factors in play, such as number of subscribers and number of people contributing to the map. This does not mean that one telco is better than the other.

It seems though that many of the telcos do not cover 99% of the island. You can take a look at the 3G coverage maps below:
