As 5G network is not readily available, we could only test the LTE speed.
Using the Singtel mVNO sim from Grid, we managed to get a high score of 215 Mbps. 3 CA (900 + 1800 + 2600) was probably available boosting the speed to above 200 Mbps.
In fact, this speed is comparable to some of the NSA 5G implementation in some countries. Sometimes, I wonder do we need 5G ?
