To me, 5G is Fake technology bc if you allot more/wider Frequency Bands to 4G, 4G can even out-speed low-band and mid-band 5G. .......

https://commsbrief.com/what-is-carrier-aggr...anced-networks/ - What is carrier aggregation in 4G LTE Advanced networks? - 7 June 2021
Why is Carrier Aggregation used in LTE networks?

Carrier Aggregation offers flexibility to a mobile network operator by allowing them to utilise the existing frequency carriers better. It allows the operators to combine multiple frequency carriers (or RF carriers) into one to serve user devices.

4G LTE networks can provide a maximum download speed of up to 3 Gbps with LTE-Advanced Pro and up to 1 Gbps with LTE-Advanced networks. ...

https://www.teldat.com/blog/lte-advanced-pr...e-basis-for-5g/ -
According to forecasts, commercial testing of 5G networks is set to begin in 2020. But, in the meantime, LTE-Advanced PRO already allows you to use technologies that will be included in 5G.

LTE-Advanced PRO, also known as 4.5G, is the next evolution of 3 GPP prior to 5G. But it does more than just push LTE capabilities closer to 5G. It also represents an integral part of the 5G mobile network, providing many essential services for the 5G experience today. ...

New LTE-A PRO capabilities
- Ultra-low Latency. LTE networks support latencies of up to 50 ms (RTT) and in LTE-A PRO this latency is reduced to under 10 ms. This allows you to have new applications, such as remote medical operations or remote vehicle repairs and diagnostics.
- Improved reliability (URLCC).
- High speeds (>8 Gbps). ....

To me, the government should shelf DNB's 5G, limit the use of 5G for industrial applications only and limit the number of 4G celcos to a maximum of 3, so that each 4G celco can have more Frequency Bands and improve 4G technology as in the above tech articles = each 4G celco can give higher speeds to subscribers/consumers and have more capacity for subscribers = less network congestion during peak traffic hours.
....... Of course, the government should also prevent profit-gouging by the 3 or 2 4G celcos, eg prevent price-fixing by a tripoly or duopoly or cartel.

Maybe, NW1 will be owned by Maxis and Celcom-Digi and NW2 will be owned by TM, U Mobile and YES.
....... If so or similar, this arrangement will be better than each celco building it's own 5G network because of too much duplication or wastefulness of 5G infrastructiure.

Presently, each celco has built it's own 4G network of cell towers and backhaul connections to TM's HSBB Fiber network, ie Maxis, Celcom, Digi, TM, U Mobile and YES = 4G infrastructure has been duplicated 6 times.

Remember, for essential services like supply of water, electricity, Fiber/4G/5G Internet and cellphone communications, it's better for the people to have a nationalized or regulated monopoly, eg Tenaga Nasional, TM HSBB Fiber, Air Selangor, etc = minimal or non-excessive profit-gouging of customers/people. Private companies tend to profit-gouge or price-gouge the customers/people.
....... Eg in USA, Fiber Internet services are monopolized or duopolized by private companies according to regions (allocated by the US government) which have profit-gouged the customers/people, eg Comcast.
.

.
Note that many 5G smartphones in the local market do not support DNB's mmWave Band N257 (28GHz), whose small-cells (look like Fiber Internet routers) are mostly deployed in downtown city centers and high foot-traffic venues like mega shopping malls, mega office blocks, concert halls and sports stadiums. Band N257 can reach 3Gbps download speed.
....... IOW, many 5G smartphones only support DNB's Bands B28 (LTE 700MHz) and N78 (5G NR 3.5GHz) which can reach "only" 1Gbps or 1.2gbps. ........

Is your iPhone 13 updated to iOS 16.4 or later.? If yes, maybe you need to fiddle a bit with the Settings.
.

Maybe wrong info from .......

https://soyacincau.com/2023/08/25/yes-5g-pr...-speed-for-all/ - 2023/08/25 - yes-5g-presents-two-new-affordable-5g-wireless-broadband-plans-gateway-and-flexi-with-uncapped-5g-data-and-speed-for-all
.... Yes 5G Wireless Broadband Flexi is designed for those looking to have blazing-fast wireless internet without a contract. The SIM-only plan is great for students, smaller families, or even people who are always on the go and need 5G connectivity without the headache of installation or waiting for the plan to be activated. Just insert the SIM card into your 5G device (it can be a 5G smartphone or 5G router), and you are instantly connected to the Fastest Mobile Network in Malaysia. A very flexible plan for anyone and everyone. ...
.

In that case, it may be better for you to test YES's 5G coverage at your locations by buying a RM10 YES Prepaid 5G Starter Pack, ie buy the 5G router only if tests pass. If not, just cancel the plan - thereafter, you can try other celcos.

AFAIK, the latest iOS update for iPhone 13 is iOS 17.0.2, released on 26 Sep 2023. The next latest is iOS 16.7, released on 21 Sep 2023. .......

Did you do the speedtest with your updated iPhone 13.? Are you receiving 4G+ or 5G signals.? Normal 5G signal = >100Mbps and up to 1Gbps.

Note that DNB's 5G cell towers transceive mostly on the mid-band frequency of 3.5GHz = 5G NR Band N78 (with a huge 6Gbps bandwidth capacity to be shared by active subscribers) = which has a short range of about 1km and bad object/wall penetration. So, you will only get good signal reception if your location is within 1km of the nearest 5G cell tower and your 5G device is near the windows or outside the house/condo, ie not in the living room, kitchen, bedroom or office.

AFAIK, signal reception is the same for both 5G smartphone and router.

To check DNB's 5G cell tower locations wrt your own locations, ......

.

NB - AFAIK, most 5G routers can be fitted with a wired external antennae that should be placed near the windows or facing outside, towards the nearest 5G cell tower, ie the router can be placed further inside the house/condo.

Fyi, .......

https://www.nytimes.com/2011/01/09/realestate/09posting.html - Improving Cellphone Reception in Tall Buildings - 9 Jan 2011
.... Such problems arise on higher floors because most telephone carriers have installed antennas on building roofs relatively low to the ground, to reach cellphone users on the sidewalks. Until recently carriers had not anticipated such demand for cellphone access up high. ...
= so, floor levels higher than 30th floor of a tall building may not get any cell signal.
.
Also, 5G cell signals (on frequency Band N78/3.5GHz) have weak object/wall penetration = 5G devices should be facing outside, eg near windows or balconies.

Maybe, try adding a SIRIM-certified 5G cell signal booster for 5G phones or an external antenna for 5G modems.

Afaik, very few Android 5G smartphones support DNB's 5G mmWave 28GHz/Band N257. Even the iPhone 15/Pro/Max do not yet support it.

Note that the closely-packed 5G mmWave smallcells (like Wifi routers/modems) that have a limited range of about 50m and are easily blocked by objects/walls, are mostly only deployed in high foot-traffic areas, eg downtown city-centers, mega shopping malls, concert halls, sports stadiums, mega office blocks, etc.
....... So, 5G mmWave is of not much practical use for most ordinary consumers.
