T-Mobile USA has already launched 5G SA for general consumer use since 2020 for it's low to mid to high band 5G frequencies. It's low-band freq are 600MHz, 1900MHz and 2500MHz, which give good indoor coverage. .......

https://en.wikipedia.org/wiki/T-Mobile_US
....... On August 4, 2020, T-Mobile launched standalone (SA) mode across their national 5G network, becoming the first operator in the world to do so.[92] They also stated SA mode improved 5G coverage because a connection to a mid-band LTE cell was no longer required as it was in non-standalone mode (NSA). ...

So, deployment of 5G SA for general consumer use depends on celcos' company policy.

AT&T and Verizon should be following suit soon, ie deploy 5G SA for consumer use.

New report also confirms private mobile networks now seeing increased deployment of 5G SA across multiple sectors. #pressrelease - August 2, 2023
SHEFFIELD, U.K. – 115 operators in 52 countries and territories have invested in public 5G standalone networks, according to the latest GSA data. This equates to 21.4% of the 535 operators known to be investing in 5G licences, trials or deployments of any type. Of these, GSA data confirms that at least 36 operators in 25 countries and territories are now understood to have launched or deployed public 5G Standalone (SA) networks, two of which have only soft-launched their 5G SA networks. ...

AFAIK, iIf you buy one of the above DNB-approved 5G smartphone today, it's firmware is only 5G NSA capable and compatible with DNB's 5G technology, not yet 5G SA capable. If 2 or 3 years later, DNB1 or DNB2 launches 5G SA to replace 5G NSA, your then 2-3 years old 5G smartphone will need to be able to be updated/upgraded over-the-air by the OEM (eg by Samsung or Apple) for 5G SA capability.
.

Note also that every country often requires different 5G firmware for it's 5G smartphones, eg in general, you can't use a 5G smartphone bought in China, in Malaysia or in another country.
.

best 5G coverage/battery power for smartphone is low and mid band same as 4G spectrum

waiting DNB 1 700mhz n28 turn on
DNB 2 more likely using exist 4G spectrum i think n1 like sg

n78 is good for fixed wireless terminal @ wireless broadband

We can only hope that the second network is 5G SA.

For people who care about using 5g SA in few years to come, they would just buy a new phone again. People who use their phone for as long as it can last probably won't care about 5G SA, because current 5G NSA is more than sufficient.

Fyi, .......

.... Standalone technology allows 5G to reach its full potential with high speeds, low latency, and high bandwidth. In this way, it saves money for carriers and enhances user performance. As of now, approximately 35 service providers have introduced or set up standalone networks. ...

= high bandwidth likely means higher user/subscriber capacity per 5G SA cell tower for it's low to mid band frequencies, eg from 500 active users per 5G NSA cell tower to 1,000 active users per 5G SA cell tower.

= for some T20 and M40 consumers, it may be wiser to buy flagship 5G smartphones today from Samsung or Google.

I am just a layman user, so I will not wait for 5G SA.

I will change as soon as my 2017 Samsung Galaxy S8+ give problems.

So far so good

Fyi, Singapore should already have 100% 5G SA coverage, eg by Singtel. .......

https://www.statista.com/topics/11210/5g-in.../#topicOverview - 5G in Singapore - 21 Dec 2023
.... Singtel, StarHub, and M1 have been responsible for operating 5G networks across the country, and the rollout has exceeded projections. Singtel achieved standalone 5G coverage of over 95 percent in July 2022, three years ahead of the 2025 target set by the government. The country thus became the first in the world to be fully covered by a standalone 5G network. ...

Singtel's 5G SA low-band frequency is on 2100MHz = quite decent indoor coverage or signal reception, compared to it's mid-band 3.5GHz or 3500MHz freq. .......

https://en.wikipedia.org/wiki/Singtel

For deep inside shopping malls+basement-carparks, office buildings and underground MRT, Singtel has probably deployed low-powered 5G SA signal repeaters or boosters, eg at every 100m - low-powered repeaters to minimize radio interference to the main high-powered 5G SA cell towers that have a range of >1km or 1,000m.

Not surprising for Singapore. Malaysia telcos do it by demand in urban areas, hence our 4g still sucks after more than 10 years. Just wait and see how gov will regulate the second network later.

So far for me...

4G is sufficient enough...

As for the question on coverage...
Some my friends using 5G compatible devices saying coverage not maximum yet... Always dropped to 4G...

I don't really sure what's it's mean... I cannot test because no 5G compatible devices 😋

you got 5G signal in the understation tunnel & station?

Last time I hopped on MRT (early July), there is zero 5G signal underground

It took more than 5 years since the 4G first launched in Malaysia to cover the Kelana Jaya LRT line. The MRT line was an exception because it was newly built back then so it equipped with state-of-the-art technology. Hopefully it wouldn't take so long for 5G, it is almost 3 years since 5G commercially available on YTL Yes
