It seems like the Singapore telco market will be very hot with the new MVNOs and TPG launching their plans in the 2nd half of the year. While going around Choa Chu Kang, our reader accidentally search and found the suspicious 525-10 Network ID. A check on IMDA site shows that it is actually TPG.
It looks like it is doing some testing. Are you able to find it when you do a manual search of different networks ?
