LTE band 20
secret band used by YES 4G LTE, umobile, digi, maxis 

Digi and MAXIS not sure, but U Mobile and YES are using 4G band 20.

When I put my U Mobile in the oppo or vivo phone without this band in my room ( as I mentioned before ), 4G become H, just 1 bar only and totally cannot online.

After that, I put it in the phone with band 20 in the same place, the line straight away go back to 4G, almost full bar most of the time and can online.

If it is not this problem, can you explain what is the reason?

For 4G LTE, UMobile first used only Band 7 = 2600MHz nationwide in the early 2010s, and then gradually added Band 3 = 1800MHz and sporadic Band 1 = 2100MHz from 2017 onward, ie likely gradually in major city areas only.

LTE Band 20 is specific to Europe only.

ITU Region 1 = Europe and Africa only. If YES has deployed LTE Band 20 commercially, it is breaking international telecommunication agreements.

Actually the tower location to your area also contribute to slow speed..

I mean if there's any interference.. there's possibilities...

Thanks for all the feedback. It is now appearing beside the carrier name. Not sure what I did though.

GX50 no need Wifi-calling = all domestic voice calls/SMS are free = can use cheapo or old phones.

That's why they give peanuts free quota only 😂

I do a speed test tonight too. Maybe you at location not many people use umobile.

At my location umobile speed is just impressive

Wow speed slightly improved

Well nothing to be surprised..
U Mobile in Borneo states sucks big..
That's why others like Digi or Celcom rules.. even Maxis, the so called market leader 50/50 only 🤣

Didn't get what me paid for ... temporarily...LOL...

Digi network is the most congested. When people complain and complain, Digi would make those empty promise like "Digi proposed to install a new tower at your location", and it'll just ignore the case.
I think Digi cares money only, it'll never care its network good or bad. Look at Digi plans give a lot of quotas + loyalty rewards, what for when it can't be consumed up.

I believe U Mobile would overtake Digi some days. U Mobile has been getting awards, whereas Digi = "no news is good news".

My u mobile sim card showing no network all the time.. I wish I can go back Msia. Currently stuck in sg due to coc-19.. Please advise is the any other alternative to recover my sim card

Celcom is more reliable(= less dropped Internet connections) for online gaming maybe because it's 3G network is still well-maintained, eg for it's rural customers = can get 3Mbps on 3G. 3G can be the fall-back for 4G during 4G network congestion = Celcom phone customers experience less network congestion = less dropped Internet connections.

In comparison, U Mobile has re-farmed most of it's 3G frequencies to 4G and it's 3G network has likely been degraded and not well-maintained = can get only 0.5Mbps on 3G = only useful for 3G voice calls/SMS = U Mobile phone customers experience more 4G network congestion = more dropped Internet connections.
