Since they have 20x20 of B28/n28 can't they just do 15x15 for 5G and 5x5 for 4G? I assume no data transmission actually over B28 since it's just used as the anchor band.

Most likely DNB proceed with DSS (Dynamic Spectrum Sharing), means that 20x20 is used by 4G/5G at same time

Certain postpaid plans only (U Postpaid 98/U Biz 98/U Plantium/U Premium) for now...

Obviously I tried with my prepaid, no SA sweat.gif

Now you can check tower location of 5G SA on cellmappet limited to KL Putrajaya Cyberjaya. Hopefully by end 2025 they rollout to other states

It's nationwide I believe, not just limited to KV area only (there is SA towers mapped in Kelantan)

Though mapping it using CellMapper requires bandlocking your phone to NR/5G only... unless you have the specified U Mobile plan with SA access.

Is this n28 SA?

The plot thickens.

Yes, DNB enabled n28 SA alongside with n78 SA for some time already since circa Oct 2024

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.

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?

About the 3rd point, Samsung actually doesn't have SA/NSA specific 5G indicator.... different market/firmware may have different 5G logo
