5G not connecting with S20 from HK in the UK with EE - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

Recently upgraded my EE contract to 5G and am unable to connect my S20 5G phone to 5G, everything else works completely (samsung pay, 4g, 3g, 2g) and 5G is supposed to work due to network band compatibility as attested by others on reddit.
I have tried several times to test 5G by going to 5G areas in London but to no avail, when I am in network mode 5g/4g/3g the max I get is 4g+. I have even changed my sim card and recgecked my contract is indeed 5G. I am really not sure why this is happening. Please can someone help.
P.S. I have even tried using sim card slot 2 as some on other forums did and it still doesn't connect to 5g. I can confirm that 5g works with Vodafone so it definitely isn't a problem with the phone. EE customer service are useless.

5G on AT&T with Unlocked

Has anyone successfully connected to a 5G network on an unlocked S20 variant on AT&T?
Yeah, I was able to no problem, just took a few minutes longer than getting an LTE connection. Got VOLTE as well, but no wifi calling/wifi texting is annoying.

S20 Ultra 5G issue

I have s20 ultra purchased originally from Telus. Its unlocked.
Now I'm with Rogers but phone do not get 5g signal. It stays on LTE even though I have 5g coverage. If I insert my sim in oneplus 8 pro I get 5g on that.
Talked to samsung and rogers and they have no idea. Both says everything good from their side.
Any suggestions?

Wrong thread? This is for the S3 Galaxy.

Do Factory Unlocked Models Show 5G or LTE+ on Sub 6 Networks?

I have the Samsung Factory Unlocked version of the S20+ (model SG-M986U1).* This means the phone is not carrier-specific, it works on all carriers (CDMA, GSM) and supports both millimeter wave (Verizon 5G Ultra Wide UW) AND lower frequency band 5G (usually called Sub 6).* The 5G UW super fast network is typically only available in highly populated areas (cities) because it that frequency signal doesn't travel very far and is easily blocked by buildings.* However you will notce the Verizon 5G coverage map shows 5G as being pretty widespread across the country.* Most of that is their Sub 6 5G Network which was launched in mid October 2020.* The 5G Sub 6 network, to my understanding, is using some of the same frequency bands as 4G so essentially it's really an amped up 4G signal using what is called Dynamic Signal Sharing (DSS)*(A lot of people don't understand all this.)*
I'm curious if there's anyone on the forums with a factory unlocked version of the S20 (typically the model number I think has a U at the end instead of VZW) can confirm if their phone shows a 5G icon when you are in sub 6 5G or does it show "LTE+"* I read somewhere the unlocked phones show LTE+ because technically that is what Sub 6 band 5G using DSS really is and 5G in that case is more of a marketing term.* Because different carriers use different terms for different networks, the factory unlocked phones can connect to all the different 5G networks but they can't accomodate all the different marketing terms.* I'd also be curious if when connected to the millimeter wave 5G in the cities if these factory unlocked phones show the "UW" designation which is bascially a Verizon marketing term, or if the phone just shows "5G".
There was also an article that talked about these phones needing a software update to use 5G and supposedly the updates were pushed out right after Verizon announced their Sub 6 5G network launch in mid October. But the author wasn't sure if the Factory Unlocked non-carrier specific models would receive the necessary update. Considering Verizon and Samsung just signed a 6.5 Billion Dollar agreement for SAMSUNG to further build out their 5G network, I would be very surprised if it were the case the factory unlocked models didn't get the update.
My S20+ model SG-M986U1 is showing Service Provider SW Ver. SAOMC_SM-G986U1_OYN-VZQ_QQ_0027 wondering if that's the 5G compatible version?
The other thing is a lot of people just swap SIM cards when they get a new phone. With 5G in most cases, if your SIM card was issued may months ago, you need to go into the carrier store and have them give you a new 5G compatible SIM card. I honestly can't remember if my phone was showing LTE or LTE+ before and after SIM card change. I tested the bandwidth after the change and in a strong signal area got 60mbit download but I didn't have a pre-SIM swap test in that area to compare to unfortunately.
Well I feel like I'm going in circles but now found a Reddit thread that confirms what I originally suspected.
The Factory Unlocked (model ending in U1) S20 phones apparently have not got the update from Samsung yet to allow sub 6 5G connection. But there is a hack in that you can change the carrier network code to ATT even though you are on Verizon and it enabled the N5 band which is what Verizon uses for their "Nationwide 5G" To do this you dial *#272*your IMEI number# Then select ATT and Install and change network code only. Phone will reboot and now you will see 5G UW symbol.
I tried the CSC change on my factory unlocked S20+. I ran three successive bandwidth tests on bandwidthplace.com before and after the change so 3 times on VZW and 3 times on ATT. As others have alluded to the LTE DSS Sub 6 Flavor of Verizon 5G is on average about the same speed as 4G LTE+. So I just turned it back to VZW and will wait for the update from Samsung. I'm surprised a month and a half later it still hasn't got the update to allow N5 band on Verizon.
I'm also wondering is the S20 always show 5G UW when connected to any 5G including sub 6 5G and not actual millimeter wave ultra wide 5G? Or is that just a side effect of "spoofing" the ATT carrier code when actually on a Verizon network IMEI?
Hello Jazee, this is my first response to anyone on xda, and I know that by now you probably have your answer I notice this is an old post. I have an unlocked Samsung s20 5g. And depending on where I am, it says 4g let, and when I'm closer to the city, or hold my leg right(I live in the country), my phone shows 5g. It's shown lte+ before. I think it depends on your carrier. Some I've noticed share 4 and 5g lte simultaneously depending on the current speed. As you mentioned earlier, 5g signal doesn't put up a big fight when it sees a tree or building. Anyways, that's my 2 bits worth, hope this helped. BTW, lte+, when I get that, it is pitiful. Nothing like either 4g lte or 5g lte.

Question Will UK variant work on AT&T?

I need unlocked/dual sim. If I buy the UK variant, SM-F926B/DS, will it work on AT&T network? Will I get 5G/LTE? Will it update? Thanks!
It should. The spec sheets for the phone does not show any variance in the radio's and frequencies they are compatible with in regards to where it's sold other than the ROM's with the carrier configurations pre-configured.
Doesnt the US version have a mmwave 5g antenna the UK version doesn't have?
If correct, how would this affect me? Thanks!
I would be very careful. In 2020 I bought unlocked Note 20 Ultra in Czech Republic and brought it to USA to be used on AT&T network. Unfortunately the 5G bands are not compatible and I didn't get 5G at all. Otherwise the phone works fine, you get LTE speeds and little bit spotty coverage. If you can live with that, you will be ok.
I use an international note 10+ n975f in USA on ATT and my line was shutoff last month because of a new company policy that will be fully in effect Feb 2022. Only u/u1 variants will work on their network...must have volte working and be a device provided thru ATT...not imported. I recommend a different carrier.
These phones will keep working on AT&T after the 3G network shutdown
AT&T will shut down its 3G network and require HD Voice support by February 2022. Check this list to see if your phone will make the cut.

It sucks. They did send me a free note 9, but...I need a new carrier.
Interesting. I’m on an unlocked, dual-SIM, Note 8, N950F which came from Singapore. I don’t remember how long I’ve had it, but I think it’s been around 5 years. It’s not a 5G device, but it is 4G/LTE and supports VoLTE. I think AT&T knows about it because I think I had to provide them with a S/N, M/N, and IMEI years ago. I’d like a 5G device and this one isn’t holding a charge for a full day anymore, but otherwise works fine on AT&T for now. I’d really like to stay with an unlocked, dual-SIM.
