@all
it will randomly drop to 4g for a few seconds without reason then back to 5g again.
but when the network drop to 4g the internet is non existent, thats what annoying.
i dont think the problem on my side tho, using difference device also same issue, even im directly under the 5g tower also same issue.
mnp in and out few times also same.
postpaid prepaid also same.
now not using them anymore.

yes, I experience this issue lots of the time.
I subscribed U98 just to test SA network , and so far I've used UMB few weeks , the 5G experience sucks.
If I lock SA and perform high throughput test (Speedtest every seconds) , the handover between NR N78 cells are very good and seamlessly, I don't see any disconnect issue happened.
But , things become worst when device is standby-ing , meaning no high throughput , the 5G connection will still be "connected" but Internet IS NOT working and call thru VoNR also NOT working.
Yes , U Mobile have VoNR for SA network.
It seems like U Mobile 5G Core Network is having some handover issue on SA. I got this issue on NSA sometimes but it's way more stable compare to SA only.
