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.

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.

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.

YES is known for its unstable connection, I was also an user of YES, but it always gone out of service,  cannot tahan then change liao
That's also why currently their 5g package is the cheapest

And tplink x50 5g also has mesh system built in. Not sure about zyxel.

Deco Mesh is technology only used in TP-Link Deco products for Mesh networking.

In my case, i use Deco X50-5G as main, connected to 3 units of Deco M5.

Even connecting the deco x50 with asus system through LAN also cannot get them working? Deco x50 can be used to connect wirelessly with other deco mesh unit.

No.
Phundeck LJ maxsheet 5G is total sheet.

Same lokasi same 5g router:

YES 5G Home: max speed no cap, can torrent without VPN
U Mobile 5G: max speed no cap, cannot torrent without VPN, torrent must turn on VPN

But,
LJ CBB Maxsheet 5G: speed throttle to 300-500mbps, some apps or site like fucuking jewtube fucuking buffering, anything google, latency at fucuking least 2 seconds before anything can load. Shopee Live fucuking lag. But can torrent without VPN.

Once I turn on VPN, jewtube, google services suddenly become very fast, Shopee Live dem smooth, but speed still 300-500mbps.

I have at least 5 fucuking tickets with maxsheet, told them no VPN, everything slow, once turn on VPN, fast.
Ding dong ding dong until so called apalan 3rd level technician call me ask again apa masalah, i had to explain to him for the 8244634th times the issue:
No VPN slow, turn on VPN everything fast again. That so called malan 3rd level retardian have the audacity to tell me maybe it's the sim card problem ask me go center change sim card. Tunama geh hi minyak api naik sampai kepala hati terbakar that SH told me change sim card.
Maxsheet not only sheet network, staff also total sheet.
