Hi!
Hey any functionality lost by using the unlocked version on T-Mobile ?
Thanks
When speaking to Samsung about this, they told me all T-Mobile bands are supported including 5G on the unlocked versions. What you may lose is video calling (who cares) and possibly wifi calling. But in the past I've seen threads were talking to higher-level techs at T-Mobile can enable those features.
I noticed Samsung checkout page didn't ask if you need a SIM for the unlocked phone. In the past it would give you an option. So curious if you will need to go to the store for a SIM.
Thanks . Video calling is big with me . Rats
My Note 9 was unlocked from Samsung but video calling and Wi-Fi calling work fine. Not sure about this phone though.
Won't you just be able to flash the T-Mobile firmware via Odin if you get the unlocked? Then you get the best of both worlds. This is what I did with my Note10+. Got the Unlocked from Samsung then used Odin to get the official T-mobile firmware.

Same here
i had an unlocked note 10 + on tmo and had no issues with video calls or wifi calling. i got from the samsung site that the note 20 has an esim which i would guess is why you dont see any wording for a conventional sim...

I currently use an unlocked note 10+ on tmo that isn't flashed. The only limitation is that I cannot do tmo-to-tmo video calling. It may simply be a setting on my end but I never looked into it as there are so many options. Everything else works fine and I seem to get every update at the same time.

To fix that issue you can flash TMobile rom onto the unlocked version.

Thanks. I haven't flashed a rom before but there's lots of info available. If I don't upgrade to the Note 20 then I will flash the TMobile rom onto the Note 10+. If I do upgrade I will eventually flash the Note 20.
TMO user with S20 Ultra here. Don't use video calling so I could not say. Wifi calling works.
Third party VVM apps do NOT work and TMO's downloadable visual voice mail app is garbage IMHO.
When I put my VZW sim in the same phone the Samsung VVM app works beautifully.
Unlocked S20 Ultra 512GB here.
"5G" works on TMO where there is coverage however the speed tests show LTE as connection type. Interestingly enough some of the speed tests actually show 5G. Not sure what's going on with that. Have reached over 200Mbps down on TMO "5G" a few times. Most of the time it's the same speed as LTE. Don't care, it works, hot spot works nice too.
If you were to (properly) flash TMO firmware (in theory) it SHOULD make your phone just like a TMO bought phone including the cheesy jingle when booting up. Never tried it, I like the slim as possible approach. Plus the ability to drop in a VZW sim and it just works IS a MUST for me.

You don't lose wifi calling or video calling using unlocked on TMO.

Only if you use TMO's downloaded app which is utter $4!+ IMHO.
I hate it so much I just dial in to listen the old fashioned way. I screen calls anyhow so the ONLY time it rings I know who is calling so not really a big deal. If callers don't have the secret PIN they get hung up on! F robos!
What about roaming on T Mobile partner network? Will I get a network on my UNLOCKED Galaxy Note 20 Ultra if I am roaming on US Cellular or any TMobile partner Network?
Will my Unlocked Galaxy Note 20 Ultra support all 5G bands from TMobile? (Low, Mid and High ) Layer Cake so to say.
What about SA 5G (Stand Alone 5G) that TMobile just launched. Will the Unlocked Galaxy Note 20 Ultra support it?
Sprint frequencies
I'm mostly concerned about the Sprint frequencies T-Mobile is picking up.

Just received my S9+ 256GB Korean Variant SM-G965N. This is going to be my experience with this particular variant and its compatibility with the T-Mobile network. Currently it shows I'm connected to Band 2 LTE but the speeds I'm my area are very slow. Withing the next couple days I'm am going to test the network throughout my area in Cali and test speeds and connectivity and report back. Unfortunately the build of Samsung pay is customized for S.korea only and not compatible here in the US.
Current build after first update is G965NKOU1ARC7
Baseband versions G965NKOU1ARC4
I have some data speeds this afternoon while out driving. The long screenshot is from my G965 and the short list of from a T-Mobile variant S7 . Connection to the network itself has been stable with no notice of dead spots or issues switching towers, if anything I'd say the switch is faster from what I've notice between devices.
Excellent...a lot of us have been waiting for this...thanks for testing...
I was curious about this. I have a G965U1(S9+ Unlocked North America variant).
I have a second phone with Ting GSM(T-Mobile), and I tried a few speed test. The phone configured it self to send calls over wifi when ever I connect to wifi. I found that peering with Sprint appears to be an issue.

Hey guys,
I also got an international S9+ (SM-G965F) but from Germany Unlocked (DBT). So far the signal seems to be great. Will post some Speedtests later. The only downside is that wifi calling and VoLTE is not there. It was working with my German sim. Other than that it's been great.

Have you flashed T-Mobile CSC? I assume you have to root and make a custom zip to flash the files. If the phone thinks it's a legitimate T-Mobile phone then it give you full speeds.
Also is the Korean phone a duos? Dual SIM?

I dont think that is possible. Isn't the Korean version run on Exynos? Flashing a Snapdragon CSC for TMB would be wonderful but I think would mess lots of thinks up. Hopefully someone will be able to change the CSC to work on the exynos processor.
Okay so the weirdest thing happened to me. I tried to use Samsung pay a few days ago. I used app cloner to copy the working version of my note 8 snapdragon and sent it to my S9+. It didn't work and gave me the connection error. Now I was just on the phone and out of boredom I tried to open Samsung pay again while on the phone and it magically worked. It asked me for my Iris and fingerprint and I was able to add my cards again. Again, this is on exynos DBT from Germany without any modifications or OEM unlock.
Hope this will help at least with Samsung pay.

I have a friend that works at Sammy S. Korea that picked it up for me, as for Samsung pay the apk is specifically built for the Korean market and has a different activation process which requires a text from one of the local carrier networks which I cant bypass.

The build is completely different and won't work because of the region and coding in this software build. I am not ready to root yet so I'm going to tinker with software that's official and see what I can get working, improve on for now.

Not really. I'm also on T-Mobile USA and have the German exynos. The apn settings were loaded correctly. Maybe check them in the settings and make sure it's set correctly. The only thing that is not working is VoLTE and wifi calling.
Samsung pay finally works with the credit cards but the membership doesn't work.

ow did you do the initial setup with or without the T-Mobile sim inserted ? I noticed when I originally set my Korean variant up without the sim, for some reason I did not connect to LTE in my area and after oem unlock and restart/ full wipe it connected perfectly since.
I've got the same model, I'm with ATT, speed test shows 31m down and 10m up, but actual downland from play store is less than 2m...
Hi do you receive benefits in your samsung members app?
Yes if we can get T-Mobile CSC settings to enable VoLTE and Wifi calling then I will root.
I am recently realizing Samsung Pay is not everything it's cracked up to be. It doesn't seem like they have many 3rd party companies registered, so I made a custom loyalty with the barcode, but it doesn't work when it's scanned at checkout. Funnily enough, I have the loyalty in GPay as well, and it works just fine. Also SPay doesn't seem to work in gas station cc readers where you stick the card in and pull it out instead of swipe. Unfortunately it just doesn't seem like the technology is there yet where we can ditch traditional cards.

Current Note8 user on ATT (phone locked to carrier). I pre-ordered a Note20 Ultra from Samsung direct, unlocked version. Have been off XDA really for a couple years and not rooting/modding much lately but have read that ATT will not allow unlocked phones on their network to use WiFi Calling and/or VoLTE. If true, are there workaround options for me (assuming I stick w ATT as the carrier I mean) to get these to work, or should I cancel the unlocked model and order the ATT version? Was hoping to root eventually and remove bloatware / play w custom ROMs again on the Ultra etc etc. - that is why I ordered an unlocked version.
Thanks gents for the guidance here! Best forum around for us phone geeks

Did not work for me on the unlocked note 10+. Worked right away on the tmobile.
Att was actually fun to have. Nothing that att expected worked on the unlocked device. For example I had unlimited hotspot, despite it was not included in my att plan.

That's bizarre. I am rethinking this unlocked route. I must have wifi calling since signal at the house is terrible in my area. I don't need the drama of uncertainty if this will work or not. Might as well cancel the unlocked one and just upgrade via att. Oy. Wtf is with att these days? They lost my directv account last year and now their wireless policies are looking like a royal pita.
I don't think you have to worry .... ATT seems to consistently allow Samsung unlocked devices to have carrier functions
You just have to flash the U CSC as mentioned above. Worked for me on Note 10 and is currently working on a s20 ultra device

I strongly recommend switching your order to the ATT model. I got my note 10+ unlocked based off the suggestions found here saying that flashing the att firmware would give me all the features, and I've been through a year of headaches.
For a little wile i was able to enjoy wifi calling, voicemail and VOLTE, but after my first software update the features were lost. i was able to get them back briefly by putting my sim back in an old Att phone and keeping it for a day or two, but that trick never lasted past a week. I've tried re-flashing the software, switching back to unlocked and then back to ATT, basically anything i could think of and it never worked.
calling ATT didn't help either, as the reps gave me a canned line about not supporting outside phones. the whole reason I'm updating to the 20 ultra is to just get my phone fully functional with an ATT model

Thanks darth. Yeah, I switched to the att version. Hate the hidden tracking bloatware etc that comes with it but must have a very workable phone for daily work calls and wifi calling is a must. No drama is my motto these days. Thank you for reporting your experience.
I had the same situation with my unlocked Pixel 4 XL, keep calling ATT until I got the right person to modify my sim to allow WiFi Calling to work, that's my plan when I get my unlocked 20 Ultra.
I'm not a gent, but I doI have the Note 20 Ultra in for review and am using it with an AT&T SIM. VoLTE works, no option for WiFi calling.

What worries me is the 5G. Will unlocked work for ATT 5G?
It does on my unlocked Galaxy S20+ 5G. The Note 20 Ultra is a ways to release and their system doesn't yet correctly identify the IMEI, so I can't say for sure what will happen after release day.

Hi Lisa,
Your reviews are the best, so thank you first of all. Can you check if it has any eSIM capabilities? Supposedly S20 was going to get an update to allow eSIM use in US but that never happened...
Thanks . I'm not seeing anything under connection settings on our US unlocked Note 20 Ultra (there's no IMEI listed or cellular network option listed under connection settings when no nano SIM is installed. EsimClient is running on the phone, which makes me think the hardware must be there. EsimClient is not running on my GS 20+ unlocked.

Great, thank you for checking and comparing with S20+ !
eSIMClient running gives me hope that we will get eSIM support in an update...Still perplexed how or why Samsung has gone out of the way to disable eSIM on US variants when Apple, Google support it.

Ha! Thanks Lisa (love your tech vids!!) - I switched to the ATT version. Supposed to be here 8/21. I can't take a chance with wifi calling being borked, or that just that I may need to Odin-flash updates or CSC packs periodically to keep up with the monthly patches (ie force an unlocked unit to keep working on ATT's network if my previous firmware gets overwritten etc. I mean). I guess as I got older I went from a tech pioneer and adopter to just an end user LOL.... I just need it to work. Maybe I can do that package remove thingy and chop the bloatware periodically... we shall see once the community gets these units and starts their dev magic for us.
I guess I will need to make an appt at the local ATT store in a week to get on a new 5G plan from my current 4G one to take advantage of the coming speeds.
You're welcome- glad you enjoy our vids! With AT&T, you can simply change your plan online, no need to visit a store. The mid and high tier unlimited plans include 5G.

Could you tell me more. I have the US unlocked note 20 ultra, I put an AT&T sim in (from my note 9 unlocked) and I can't find an option to turn on wifi calling. I pretty much gave up on feature like this, because I would rather have the unlocked phone, but if it works now maybe I am missing something.

Yeah same here... Hopefully that's enough! I saw people talking about flashing a csc file but I don't remember what the point is or if it's necessary.

I have Note 20 Ultra Unlocked on Tmobile, Wifi Calling and 5G is working. Video Calling uses Google Duo and i am not getting read receipt of messages(text or MMS) in Samsung Messages App. these are the only things i have noticed so far.
I'm still a sprint customer coming from the note 10 plus. When I insert the sim card into my unlocked note 20 ultra from my sprint note 10 plus,will I be able to access 5G and have everything work properly ?

Are there any differences (Hardware like LTE, 5G Band differences or software differences) between AT&T and US Unlocked versions?
Hardware should be no difference. Radio bands should be the same. Software is different. The unlocked comes without carrier bloatware.
That is correct. The software is the only difference. I had the Samsung Note 10+ unlocked on AT&T. I couldn't get WiFi call or HD voice. This time I went the Note 20 Ultra AT&T version. Not a big deal. I just remove the bloatware from the phone using ADB. You can find articles on how to do it.
Weird that I was told by VZW that I couldn't wifi call on the unlocked version. But I can.
I had the U1 version on ATT. Worked great. Some menus missing, such as ability to choose VOLTE butncall quality was great. Has to call ATT to change to a 5g plan for 5g.
By the unlocked version, are you referring to the SM-N986B/DS? I am researching as well and I am on the AT&T network.
Edit: my bad misread title.
I had a U1 N10+ and as someone else mentioned, no wifi calling or HD Voice (VOLTE). Even flashing the U firmware. ATT typically has to Whitelist your phone to unlock those features. Running the U would unlock Video Calling (useless unless the other person is also on ATT) and Advanced Messaging (also an ATT only service). The day I got my N20Ultra, I popped my ATT activated sim, and no VOLTE / HD voice, and no wifi calling. Being on U1, the rest of the features weren't available (video calling, advanced messaging, vvm) which isn't surprising since it's debranded.
In another thread, it showed that Factory Unlocked N20Ultra will have HD Voice hut NOT wifi calling. That's fairly new, so YMMV. Saw the post earlier this week. Not sure it's it's live already or in the works. Some phones had support for WiFi calling and HD Voice, but the N20 series were showing only HD Voice at time of article.
I've since dumped att for Metro (Tmobile) for a few reasons, but primarily their reluctance for fully support a factory unlocked device. They are making a step in the right direction, but honestly, VOLTE and WiFi Calling should be standard features supported. Like why wouldn't you want me to call on wifi instead of clogging the wireless towers? Both work OOTB with Tmobile.
Edit: If you have no plans to switch carriers, I'd get it through att. Even if you run U1 for now, you can change your mind later and know all the features will work on U. If you buy factory unlocked, and need WiFi calling, there's no guarantee it'll work even if you load U firmware. In the past, the device has to have the IMEI specifically whitelisted on their end.

If you buy factory unlocked, and need WiFi calling, there's no guarantee it'll work even if you load U firmware. In the past, the device has to have the IMEI specifically whitelisted on their end.

I spoke to AT&T for hours and they whitelisted my international Note20 Ultra IMEI. I still don't have Wi-Fi calling and they absolutely don't know why... I regret switching from T-Mobile to AT&T... but unfortunately have to stay with AT&T for 2 more years because of iPhone deals we got...
Guys, all you have to do is flash the U Home CSC for and you'll have all the features on ATT and still have U1 firmware on your U1 device. At least for me on this phone and two previous, the Samsung devices were already "whitelisted" with ATT
Can a US CSC be flashed to another snapdragon model, namely 9860?

My guess is no .... But not sure
So if I have a at&t version and flash the u1 firmware would I have wifi calling?

No. If you're on the AT&T version, stay there.
I can't believe AT&T would whitelist all Samsung Unlocked devices, that would really surprise me. You can buy AT&T locked Galaxy phone and unlock it with AT&T since you bought it outright, and then of course it would be whitelisted.
Still Less Features for Factory Unlocked Models?
Read through this thread and tried digging around in all other logical forums and it seems that it's still the case that one cannot get WiFi calling on AT&T with a Factory Unlocked model?
Asking because Amazon is selling the Note 20 Ultra 512GB Factory Unlocked today for $1,200.
Found a Reddit thread that has people stating there will be a Samsung update that addresses this.
Have seen various posts in various places about flashing file(s)/ROM to enable this.
Any authoritative answer as to whether WiFi Calling (and Voice Over LTE) can be enabled on AT&T with a Factory Unlocked Note 20 Ultra? Or authoritative assurance it will, soon?

They cannot. Att and att based subsidized carriers. Do not allow byod on votle or wifi calling. I have a trick to make it work for a couple hours. So I know its possible. But after a few hours their systems reprovision your device and shut them back off.

Too bad. Thanks for the reply. Feel better about passing up the sale especially since it will probably be a common sale price during Xmas sales.
And WiFi Calling is too important a feature to trade for a discount of a hundred or even two.

Yea. If you provision volte and wifi on a actual att phone and sim swap they work for a while. Usually around 4 or 5 am. Then it shuts off and never works again. Till sim swap and reprovision
VoLTE on unlocked Samsung S20 and Note20 series phones is set to "on" by default, but unchangeable (greyed out). As of right now, there is no ability to select WiFi calling until Samsung decides to grace those of us with unlocked phones that ability.

There is a long term method but it involves calling att, and getting your IMEI registered so you can get VOLTE and wifi calling. Ask customer service. I can't remember the name of the department you need to request. It takes a couple of weeks and then you suddenly get a weird sms (something like IMEI provisioned) and then it works. Did it on note 9.
I have a TMO S22U and basically I immediately flashed to U1. I'm just curious are there any advantages I'm missing out on being on U1 opposed to T-Mobile U? I know there probably aren't many but I'm just curious.
Some say U1 us better. I'm At&t so probably someone on Tmo will chime in. But for me, U1 offered nothing over U. I mean yes no At&t bloat but I can disable what I don't want on U to get the desired affect.
My biggest thing was the T-Mobile splash screen, it sounds SO DUMB but flashing to U1 made it literally 100% Samsung for me I'm just wondering what could have been lol
The only thing I heard, but I am not certain about is that you lose the TMO visual email capability. Otherwise I have not heard anything else. I am on TMO and I kept mine on U. As butchieboy said, I just disable what I do not want. In all reality, there is not much from TMO that is loaded on the system side. More of the bloat is from Samsung and Google.
Thanks for the speedy replies guys much appreciated
One thing I noticed when I did the same thing, was I could not get 5G Ultra Capacity to work. Not certain I was doing anything wrong, just wouldn't work for me.
I think I read somewhere that you do get it, but there is no icon for it in the U1 image. It will show 4G LTE. Check your download speeds.

I did, 2 days apart in the same spot, the icon showed 5G as did the speed test connection type, but the speeds were much slower than 5G UC, almost 400 Mbps difference. Switched the firmware, back to the insane, almost WiFi type speeds.
Did you check the mobile networks setting to make sure 5G is available and selected?

Yes, that was my first thought. It never quite worked the way I should have.
preinstalled crap apps on tmo firmware
The main benefit for me on the unlocked firmware is the built in called id and spam blocking. For att you have to pay extra and tmobile has it on its best plan. But still think it works better than tmobiles implementation. And since i change carriers often i like to always have caller id and spam blocking no matter which one i use.

Can I ask what specific firmware you used to flash to unlocked?

I downloaded the S980U1UEU1 firmware which on the latest update ends with AVCK. Used Frija to download it
Carrier firmwares usually get updated a week before the u1 series does.

Would've just been a considence. U1 firmware does connect to 5G UC just look at the service menu and it'll confirm if your connected to N41 or not.
But I moved back from u1 to tmv U firmware due to having weird call /sms issues where it would just stop working and only fix was a reboot. Hasn't happened since switching back to U firmware.
Here's an interesting question..
I was on TMO and I bought a S22U from TMO (unlocked it with them afterwards) and of course it was on 5GUC and everything (I used ESIM). I got another sim (Mint Mobile) and when used as primary it would show 5G+
After a while, and just out of spite of the hideous 4G LTE TMO icon I Flashed the U1 firmware.. I'm no longer using TMO as I ported my number to Mint and it has been good.. Would it make sense to return to TMO U firmware or should I stay in U1 as Im no longer using the TMO sim?

Probably fine on U1. You're no longer connecting to anything advantageous besides updates being slightly faster with U.
I'm with T-Mobile, but purchased mine directly from Samsung.. I have the S22 Ultra U1. Since my last phone purchased from T-Mobile A52 5G. biggest change, No daily spam calls or text.. What a difference that makes.. With T-Mobile, their so called Spam blocker was notihng more than a spam attractor. Plus no more of the hidious bloat and splash screen..
I have the unlocked and I dirty flash switch between U and U1 depending on which newest ROM is out. There's absolutely no difference save for the annoying TMOB splash screen and that it says UC ... But from my extensive testing the speeds are the same whether it says 5G on the U1 or 5GUC on the U.
