Will test ltr in Muar

Maybe? No way they enable SA at all tower just for "testing"?
There are too many China devices that doesn't support B28 which causes them cannot use 5G here , perhaps SA could save these devices

There are, ENDC is enabled means data is pulled from both B28 LTE and N78 NR

Pretty sure they are testing. I could register to the SA for one second and got rejected after that

Unknown, but since few months ago all DNB tower enabled SA on N28 and N78. Not sure what taking them so long to launch SA commercially. Nowadays many 5G towers are heavily congested and somemore N28 and B28 is DSS. Not sure what's their next plan. Indoor coverage also only available in certain government and hospital buildings only.

U Mobile 5G SA
Not really stable though, suspect UMB core network registration got some problem
Some IBS like UTC Pudu have SA Signal but can't register , says timeout
U98 (I sign up just to test SA , need to use min 90 days)
QCI 8 / VoNR

Forgot to mention DNB actually enable MFBI at their 5G Portal , showcasing their Private Network
N77 and N78

Yes , surprised cuz even U Mobile never mention it.
But seems like U Mobile disable every services when attach to N28 only. Cant register to data services nor voice services. Will fallback to LTE or N78 if in DNB N78 coverage.

Frequently got disconnected on N78 and will get either radio_failure or NR Registration Timeout, like even ur status bar have 5G and connected to SA but the Internet is not working. Have escalated to UMB for check.

This is normal, even with U Mobile 5G SA enabled plan, you can connect to N28 but they disable Data & Voice on N28, meaning that even you registered and attach to N28, you can't make calls / SMS or surf Internet because U Mobile disable them on N28. Only N78 work and I can say their SA experience is bad, very very very bad. Initially I thought this is caused by my device (Pixel), but end up my friend that recently upgraded his plan from 68 to 98 and using Honor Magic 7 Pro also getting same experience on SA as me, very very very bad, especially very inconsistent and unstable. U Mobile really need to fix their SA handover / connection together with DNB.

Just curious when will DNB expand it's tower capacity, some of the tower around KL is already reaching maximum, N78 100MHz + B28 20MHz doesn't help, switch to 4G is better and faster.

Nowadays DNB introduce Fake SA eh
B28 totally no transmission at all

So far the one live i think is only this, SA only

Not sure does this 5G tower belongs to U Mobile but can 100% guarantee not DNB because DNB is using another tower and their 5G radio unit not so long like this
Huawei MetaAAU? If yes then it is U Mobile new 5G network

Ermm very long time ago, just now when u try to register with not supported plans will failed. Inside NSG shows N1 mode not allowed. U Mobile P98 SA works with DNB SA

My U98 is terminated so can only scan thru signal
N78 with UMB PLMN only in SIB1

Got one questions, U Mobile claims their network is 5G SA only.
But :

1. SA is only available to certain plans (https://www.u.com.my/en/personal/support/faqs/others/5g-sa)

U Postpaid 98​
U Biz 98​
U Premium​
U Platinum



2. Their ULTRA5G is accessible by any 5G-enabled rate plan (both Prepaid and Postpaid)



3. SoyaCincau / Lowyat.net Test Photo shows the Speedtest is performed by Samsung devices, where Samsung Devices have different indicators for 5G NSA and SA. The picture clearly indicates the current connected network is 5G NSA instead of 5G SA. U Mobile may not use different logo for 5G SA as other CSC / telcos. (Example : Vodafone NL)


https://www.lowyat.net/2025/362969/u-mobile...enang-bridge-1/

4. I saw U Mobile swapping / adding new RRU which includes B08 and B28 (RRU5516), which seems like doesn't support 5G NR. Then why they will need B28 in LTE if their 5G network run in SA only?



So is their 5G network purely 100% run on SA only? or NSA both live like DNB?

Interesting, i remember i saw some post mentioned SA 5G indicator is different. But yes I agree that different CSC / FW have different 5G logo, like the one for CN is just 5G without box

UMULTRA5G is running on NSA+SA
ENDC with B28b and also 1/3/7
SA is NOT available to non SA supported plan (N1_mode_not_allowed)
Speed quite impressive, partially due to can ENDC on 1/3/7 as well
UL only using N78+B28b

Because at the end both of them have CA
NSA B28 + N78
SA N28 + N78
The N28/B28 is DSS-ed
Both of them doesn’t make big difference in terms of speed because it’s the same spectrum
