If U Mobile's DNB2 launches as 5G SA with a low-band frequency of 600MHz (eg 2X20MHz = 800Mbps bandwidth capacity) = the 5G cell tower has a long range of >2km, DNB2 can achieve 80% coverage in about 1 year.
....... By not over-selling initially, eg limit 100 subscribers per 5G cell tower, each active subscriber can get 8Mbps during peak traffic hours in urban areas. More subscribers (up to 500 per cell tower) can later be added as more 5G cell towers are built/deployed together with the shorter range mid-band frequency of 3500MHz.

In comparison, DNB1 launched as 5G NSA with the mid-band frequency of 3500MHz (1X200MHz) = it's 5G cell towers have a short range of <1km = more cell towers needed to be built/deployed to cover a certain area. Hence, it took DNB1 about 2 years to achieve 80% coverage.
....... On top of that, 5G NSA's mid-band frequency of 3500MHz has poor indoor signal and is recently also subjected to network congestion during peak traffic hours in urban areas as more 5G subscribers are added.

Frankly speaking, all this because telco don't limit the 5G speed. All go for best effort. Even 10Gbps bandwidth will get used up on high demand towers.

MCMC could have taken the approach of awarding this project to 2 telcos, balancing DNB and 2nd 5G.
If they do so just like how Celcomdigi limit their 5G to 100mbps, 5G is even slower then existing 4G. But I guest the reason of limiting 5G speed is to prevent over usage of quota which need to be pay to DNB.

Correct me if I’m wrong, but the last I heard, Umobile is sharing towers with Maxis now. If that’s true, the coverage should have improved a lot la.

I can confirm that Borneo plan has always active feature that automatically extends the validity.

I'm using U38 postpaid will I get it? 😅
