Korean Note 10+ 5g on T-mobile or At&t

Anyone have a Korean International Unlocked model running on T-mobile or AT&T here in the U.S.? If so how is the 5g network doing on this model?

I do not have one but I will give you my extensive research as I was contemplating doing the same.
The 5G band that the Korean (or any other non-T version) uses is NOT the same as the 5G band that T will use. So 5G will not work using this phone on T.
Also, please be aware that you have to pay T for a premium calling plan to actually get 5g service. The regular "unlimited" plan I was on would not include 5G service, and the plans that include 5G are MUCH more expensive. Plus you have to be in a location that actually has T 5G service!
I ended up buying a regular 4G 975F/DS instead. You can get Volte working on that, but they sure don't make it easy!

Thank you very much for the information I almost bought one glad I held off,I'm on T-mobile right now but thinking of switching to At&t when the Galaxy S11+ 5g comes out,really depends on what deals each carrier has at that time.

SM-N976V Note 10 plus 5G portability (carrier switch)

I'm looking to spend on Note 10 plus 5G, currently on Verizon but the biggest question that I couldn't find the answer is if in the future, I will have to stay with Verizon forever if I want to use 5G on this phone.
Samsung released different snapdragon models for each carrier, but what if I want to switch to Tmobile or AT&T with this phone? Is there a workaround to make these phones work with different carriers, especially with 5G?
S10 5G is out for many months, but I couldn't find a thread showing portability. Although selling the phone for a discounted price and buying other one that works on different carrier is an option, looking to find if it is practical to use 5G when we switch carrier.
Thank you

once its sim unlicked it will workbwith other carriers.. ive tried it on multiole sims from dif carriers

The lte radios should be the same, the 5g will never work across carriers for now considering theyre taping into different spectrum. Modems and antenna designs are different between the different 5g methodology each carrier adopted.

That is very nice to hear. Does the phone work with other carriers once sim unlocked without changing the phone software? Does 5G work on other carriers too, if the bandwidths match? Thanks

I may not understand much details of these modems, however my understanding is that there are some 5G bands common between carriers.
Verizon holds 76% of total available 28GHz spectrum bands and and 48% 39GHz 5g spectrum bands.
At&T holds 40% of 39GHz bands and Tmobile holds 12% of 28GHz bands. If I'm not mistaken the modem in Note 10 5G model supports 600MHz which is new Tmobile band. So, if Note 10 modem supports those 2 5G bands on verizon, technically it should work on at&t and t-mobile too? Although these may work in different cities as of now

Yes and no, I don't know if it has the right antennas, they matter to match the signal length and the obvious is how locked the radio is.
You forget Verizon are evil about keeping their phones there.
It could be the phone is capable but will never be able because it's a Verizon phone and they nerfed something.

In the past we were able to unlock blocked antenna bands using Qualcomm QPST tool and hope there will be possibilities in the future. It's not that Verizon is evil, it applies to all carriers. There has been court ruled regulations that enabled users to take their device to other networks, but blocking 5G would be inconvenience to users, as we all know 5G is the future. I'm going to grab a Note 10 plus 5G for now

technically they wouldnt be blocking anything if they just dont include the antennae/functionailt.. its then up to the user to research and purchase if it suits their needs.

Follow up:
After Verizon unlocked the phone, surprisingly 5G works with Tmobile without any modification. Of course not all the bands. Haven't had 5G signal so far and suddenly when I'm standing near a 5G antenna in downtown Manhattan, I had full signal

I have the same phone. I was not able to see 5G with TMobile or AT&T. I am also not able to get the Verizon hardware off my phone. ( boot logo, etc.) Any work arounds?

Odd. I have the 5G on VZW thats unlocked. My phone works fine with my TM SIM but does not pickup 5G even though my OnePlus 7T Pro McLaren gets 5G.

nope.
the n976v only has vzw and gcf csc codes on it which both use the vzw sales code n network code.. changing carriers should work but on network as the csc should recognize this and load the correct apns n such but the bootani n vzw stuff is there to stay..

not odd.. its a vzw branded 5g device.. its hit or miss on other 5g networks.. they typically use different bands and frequencies and 5g variants dont contain full csc for other carriers like the non 5g devices

So I'm having an issue, I'm trying to get my phone to work with Total Wireless but for some reason I cannot adjust the APN and they can't send me an update to my sim card. I can get the calls and text to work and it shows 4g but no data due to the incorrect APN. Its all grayed out with no way to add or configure it. The IMEI also says its not compatible with Total Wireless which is weird since all other verizon phones have worked before except this Note 10+ 5g.

Where did you buy this phone? I had the same issue, when I changed the code to GCF from VZW. I had to send the phone back to Samsung, as the local samsung experience store couldn't even understand the problem. GCF is for Samsung diagnostic purposes only and they had to change the motherboard board on the phone in order to fix the issue. If your carrier 5g mmwave band is one of the band used by Verizon, you'll be able to use 5G with this phone. I was able to use 5G in NYC with TMOBILE, but not when I moved to a different state.

I can relate the issue you're facing. I was using this phone with TMobile 5G in NYC, but when I moved to different state, I can't get the 5G reception. In order to understand this further, you need to understand the frequencies supported by TMobile and frequencies owned by Verizon. TMobile shares one of Verizon's mmwave band (only around 25%) and these antennas are limited to only few metro cities. Even if you live in one of those big cities, you need to stand close to the 5G antenna in order to get the 5G signal. I remember that I had to stand within 50ft from the antenna in order to get 5G signal (downtown Manhattan near Meridian Lane and Water st).

So I'm new to this. Ive got a Note10+ 5G from Verizon (SM-N976V). Ported over from Verizon to At&t. Works fine accept its on 4G LTE (no 5G... the Samsung S9+ went over to 5G no issues). I am told if I flash the phone to the unlocked firmware it should get rid of the Verizon "lock" and work. I have tried this as per help form Android Central however having no success flashing... I am not exactly that savvy with this stuff... Please help

You can network unlock it pretty easily even if the phone isn't paid off yet. Download setedit by 4a from the play store:
https://play.google.com/store/apps/details?id=xyz.paphonb.systemuituner
and change the setting "vzw_network_lock" from a 1 to a 0. You'll have to buy the expansion pack from 4a to have a foreground guardian that'll prevent it from going back to a 1.

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 What's the deal with 5G mmWave & Sub-6 ?

Can anyone explain what's the whole deal with the 5G mmWave & Sub-6 ? I'm asking because I'm in Romania, on Orange carrier, and have 5G plan. I had a Xiaomi Mi 11 which had 5G signal, but now with my P6P only LTE. Also no voLTE and no voWIFI.
I checked with them(Orange), they reset my network, tried eSIM, tried another SIM, still only LTE.
I get about 200 mb\sec, but I pay for 1.2 gb\sec(I know it won't be that fast, but with the Mi 11 I had about 450-500 mb\sec, and lower pings in everything). Does anyone know how to enable voLTE at least?

The only thing I could find from Google was this article https://support.google.com/pixelphone/answer/10082009?hl=en

Have you gotten the December update for your P6P yet? I believe it has some 5G fixes, although I don't use 5G so I can't speak about it first hand.

It's just marketing. 2.5 GHz is the suburban mid-band 5G. mmwave is the very distance limited high-band 5G meant only for stadiums, parks, and dense downtown areas.
Both are marketed as ultra capacity.

I've been reading about T-Mobile 5G. Apparently there are three tiers. The first low wave isn't that much faster than 4G. Then included with UC there's medium 2.4 ghz wave which for me is a lot faster. I live in a medium sized city and I pick up UC most of the time. I was able to get 390 Mbps with medium wave. I haven't picked up the ultra high band yet, which is of course UC also.

The chances are your phone only has Sub6 and doesnt even have the necessary mmWave hardware anyway (unless you bought it in the states) so i wouldn't lose too much sleep over it.

So my 5g phone can't connect to 5g ? Wow...nice move, google.

If it can't connect to the very short-range mmwave. You still get mid-band and nationwide 5G if your carrier has built it out.
But yes, it is a **** move that Google removes the antenna from Pro models that don't include mmwave. They just shove a piece of plastic to fill out the space.

What do you mean it cannot connect to 5G? Sub-6 will still get you more speed than you'll ever need and of course the main benefit which is capacity, also you're not going to have to stand next to the cell site to even get it, you can be miles away to benefit. mmWave isnt even deployed in most countries because in everyday use it is pointless.

Absolute nonsense ..
Here in Austria the pixel is not officially sold, 5G and VOLTE still work perfectly.

5G wont work in unsupported countries. At the ss you can see what country is supported in the Europe. You can just google it if you dont belive it (example: "5g blocked in unsupported countries google pixel")
Google blocks it, and is lying that is that countries operators fault. But it is obviously a lie. The theme is discussed from Pixel 4a 5G. Until now on the other pixels with 5G, you could install the magisk module, which unlocked everything, so how come it's the operators fault, if the lock was discovered in the software. Pixels 6/pro have a 5G modem from Samsung, so maybe that's the fault why you haven't yet been able to unlock via the magisk module
In summary, it's not about any frequencies, the Pixel 6/pro supports all 5G frequencies used in Europe. This is Google's fault alone, they are tardy and don't want to solve this problem, and probably just don't give a **** about the other countries. Best to spam on their Pixel forum and in the feedback, maybe they will finally wake up

I don't know if this helps anyone: Check carriers, their 5G networks & their 5G roaming support for Pixel phones. Make sure and choose your country from the drop-down to see the list of carriers beneath.
There's also the section above that Learn which Pixel phones can work with which kinds of 5G.

Question Verizon 5g question (13 Ultra, sorry!)

Was wondering if anyone had any ideas on why I'm not seeing 5g with a global edition 13 Ultra on Verizon in the US? I know it's missing some of the bands and I'm fine with that experience, but checking cellmapper.net suggests the areas I've been should still have some 5g availability on compatible bands. I've checked that it's set to 5g preferred, SIM was in a iPhone 13 Pro and Zenfone 9 previously, both of which were getting 5g in these areas, and I've checked that it's set correctly for preferred network type under *#*#4636*# from the dialer.
APN settings are mostly greyed out from editing, I can pretty much only add a name to one for what's allowed. VZWINTERNET entry looks fine though, and everything else such as mms/sms/calls/LTE data area all fine.
Phone is unrooted and I'm trying to avoid tinkering too much, but can unlock BL if it's absolutely necessary. I've got a US Mobile (Verizon MVNO) sim that also is only showing LTE for data if I pop that in.
Not the end of the world as I often switch over to LTE instead as it's often more reliable for me, but curious if it's still something I can get working.

Yeah that's what I was expecting for supported bands. Calling the carrier went about as well as I expected, "your Xiaomi device isn't compatible with the Verizon network, especially since it's missing Band 13. Do you have another device you can activate instead?". Looking around on Google, seems like carriers might be able to lock APN settings on a SIM, so that might be what's happening there, but not sure. Thanks for taking a look at it with me.

But B13 concerns 4g, anyway bands N77/78 have a low range and are mainly used in town.
