If you are in southern, western or northern Singapore, you might have noticed that there is a new network, probably a trial network with the code of 525-25.

We suspect that it is an old 3G network on B1 (2100 MHz) network that is being refarmed for 5G. We can’t confirm but it seems to be Starhub’s 5G trial networking running on refarmed 2.1 GHz network.

If you own a 5G smartphone and has the 5G SIM card from Starhub, you can test out the 5G network now covering 60% of Singapore.
