Question Network Connection Generally slow with the S21U - Samsung Galaxy S21 Ultra

I haven't been happy with this devices T-Mobile connection from the getgo (Jan 2021), and it seems worse now.
Is this a general consensus?
Device is updated 512GB.

3G not working with HTC shipping ROM?

Firstly, let me thank everyone who does all the SUPERB work on this site, developing software, ROMs, and tools that us normal users would otherwise never see...
Here's my problem:
I got a Kaiser with the shipping AT&T ROM on it - I'm in the US.
I wanted to get rid of the bloatware and other crap that AT&T puts on the device, and take it back to an HTC ROM.
The problem is, I can only connect to the EDGE network, and I'm only getting 40-60k transfers - I know that with my Samsung Sync (my previous phone) I was getting 1.3-1.5Mbps using the same site to test (http://text.dslreports.com/mspeed)
Is this a limitation within the HTC ROM? If so, does anyone know if newer HTC ROM's (perhaps even with WM6.1) will fix this problem, or do I HAVE to use an AT&T ROM to access the 3G (HSPDA) network in the US?
Thanks in advance for your time!!!
Do you see the icon 3G and it changes to H once you're accessing the internet? If no, you might want to check if you correctly config the connection.
I myself don't trust http://text.dslreports.com/mspeed when it runs on PIE web browser. I did the benchmark on 2 different types of connection, at&t HSDPA and Verizon FiOS* Wifi, and it comes up nearly the same speed 1.3-1.5Mbps.
*I have 15 Mbps download package.
Yes, it DOES do that (Mr President...lol)
What site do you prefer to test the speed of your 3G connection? I was hoping to use Speedtest.net, but doubt that they support mobile.
So, I guess that you're saying my connection is probably just fine, but that the site is problematic?
Thanks for the quick reply, btw!!

I don't pay attention too much on speed. But, there are many ways to confirm that you're connected to 3G network.
If the answer is yes for any question below, then you're 3G.
a. Tethering internet via your PC on "internet sharing" mode and make a call at the same time.
b. Stream any audio broadcast with bitrate above 196Kbps.
Enjoy.
Um, where do you live? Pretty much only the major cities have 3G deployed, and even then, it's no guarantee. I live in Minneapolis where 3G was rolled out last November.

I'm in Pittsburgh - I know for certain that I'm in 3G territory, as I just got the Kaiser a few weeks ago, and before that, was using a Samsung Sync tethered to my laptop, and getting 1.3 - 1.5 MBps....
UPDATE
Must have had a lousy signal where I was trying it before - I tried it again, using the same site, and was getting 500-600k - so I guess it's hitting the 3G network, but for some reason, changing the 3G icon to an H, presumably indicating HSPDA.
All's well...can one of the mod's please lock this thread? Thanks!

UK T-mobile Users - feedback on reception and poll

Could all UK T-mobile users provde feedback on how they are finding the reception on the T-mobile network? As an ex-Kaiser user, I'm finding reception is quite poor, the Diamond usually showing a couple of bars less than the Kaiser. Additionally, HSDPA performance is poor and intermittent.
Mine shipped with 25.03 and I am not impressed with the signal or data at all. I am finding it is dropping calls where my Vario II was fine.
The battery usage is quite high too so I am recharging at the moment and I think I will take the radio to 25.05 tonight....Not sure whether I should try another OS ROM.. seems too many to choose at the moment
Cheers
Aidan
I have tried all of them and now on 25.11 which seems to hold a 3g signal longer but not very strong (2bars ish) better than 25.06 but not a huge difference. I am prob thinking of moving back to 25.06 because it got more better signal for gps purposes, as i said not a huge difference in phone signal.
In all honesty Im what dissappointed i couldnt get a strong 3g signal on motorway. Oh well just wait for the next new radio to test

Poor Wi-Fi signal strenght

Hi, I finally received my S10.
After setting it up I noticed that the Wi-Fi is much weaker than on my previous phone, S5 which I had previously. Where the S5 was still clinging on 5GHz band and had pretty good 2.4GHz coverage S10 can't even manage to detect the 2.4GHz.
No issues connecting to the router, and the speeds are better on the S10, but not the network discovery. Is there something I can do? Did I get a faulty device?
Using the unlocked European version.
I think its some kind of a issue with One Ui. It happens on every samsung phone running One Ui. U can test it by going to wifi settings in any one ui phone and having some other phone side by side. You will see that the other phone simply shows more Wifi Connections.

Wifi 5g issues

Hello everyone,
I bought two Realme X50 5g from Amazon uk and I was really excited when the phone arrived, from what I read everywhere was a lot of value for the money. However just after a few hours of use I was really disappointed to see the behaviour I am having in both phones.
I can connect to the wifi 5g band without issues and I get internet, the problem is that after a while (randomly can't tell 1 hour or 10 hours depends) when I check the phone it says "no internet" and I can't access anything, I need to disconnect and connect again and the internet comes straight away.
This issue is a little bit annoying because it means being disconnected for a while until I realise about it.
I am in the UK and I have Virgin Media and was using their SuperHub 3 which has worked really well with any device until now. I tried to change the config from dual band and add 2g to the 2g ssid and 5g to the 5g ssid so they were separated so it doesn't use dual band automatically and is the same. I was suspicious the problem could be the VM router so I bought a new router TP-Link Archer A7 AC1750 which I believe is a middle range router which supports dual-band however doesn't have all the high tech technologies like mu-mimo and beamforming. Anyway I got the router setup everything and have been using the Tp Link instead an the exact same thing happens.
I am with EE as carrier and I don't have yet a 5G plan, however as soon I turned on the phone with my sim EE sent me a test saying that they have enabled VOLTE since I am on a device that supports it. I may be wrong but I am also getting the impression the issue tends to happen more frequently if I have received or done any calls, but I have no hopes on getting support from EE.
I have contacted Amazon support which was hopeless and I have sent an email to Realme support but I haven't heard from them yet.
I am starting to consider to return the phones and get a refund but if I need to get to that will be a shame because the phones does looks nice and I have been enjoying it, I like the UI and the performance is quite good.
With all said I was wondering if anyone is aware of any issues with the Realme X50 5G and the 765G SOC wifi?
Thanks in advance

Question Slow data speeds

My data is incredibly slow. I am nearly getting triple the speeds on my oneplus 8pro.
I have reset the network
Checked to see if data saver is off.
The apn is correct
I'm on T-Mobile and have the unlocked S21ultra.
Any ideas?
I am having the same problem in the same network with same phone. I was thinking it was t mobile and connecting to 5g. Trying to duo someone is very spotty unless I have full bars and sometimes not even then
I got a new sim card(r-15) hoping it helps
Same here.
2 devices, both pre ordered from Sammy, Tmo variants, both silver 128gb.
Slow speeds.
I am having the same issue and thought it is because I am using a private dns to block ads (dns.adguard) but it doesnt seem the case.
