It was just released today along with April 's security patch.

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Compusmurf:
Ok, so DUC8 or later. How does one switch to ESIM?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] VICosPhi:
Just go to your settings>connections>Sim card menu, click and hold it will say convert to eSIM
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] truckerdewd:
Security patch is March 1.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] truckerdewd:
So if I did that, could I then take my physical sim card and put it in my S21+ and have service to both phones with the same number?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] VICosPhi:
No, once you convert existing physical SIM into eSIM, your old physical SIM will no longer get service. If you want service on two separate SIMs with same number, Tmobile offers data with paired digit plan for that purpose.

This eSIM conversion allows you to have one empty physical SIM slot in your phone so you can use another carrier's SIM in your phone.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] truckerdewd:
I have paired digits on my watch. I work for T-Mobile and saw a message about eSIM for the Note20 and Note20 Ultra when I logged in today but didn't have time to read it.

I still wish we would have gotten the April Security Patch like the S21+ did.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] VICosPhi:
Good to have you here :)

Yes, would have been nice but updates have been coming out regularly of late so hopefully this was just one off.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] truckerdewd:
Thanks, I've been here since the HTC HD2 days, which was the first first phone I ever did anything with which was to be able to dual boot Windows Phone 7 and Android. Quit rooting stuff a few years ago after my V10 bricked itself while I was watching Netflix and I didn't feel the need to anymore and just don't have the time. The last few years I haven't said much, I've been more of an observer. I still do minor things like use ADB to move or hide the status bar and stuff like that. But pretty much run stock on both my phones.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] VICosPhi:
Those were the days! HTC with their fastboot bootloaders. I have also stopped rooting, as I like Samsung UI but do miss Viper4android and Nandroid/Titanium backup as Google still hasn't provided a proper backup solution sadly... Now that there is eSIM makes this more complete of a phone.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] coilbio:
So is this confirmed to be able to use 2 lines, 1 esim and another T-Mobile sim?

Or is it just converting your sim to esim for no real benefit?

From what we've seen, T-Mobile variants only have 1 imei listed.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] ekerbuddyeker:
I'd the device is locked to t-mobile, how can you use another carrier in the other sim? Would need to get it unlocked.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] a1atif:
Will unlocked version of Note 20 Ultra get this update with eSim support on Tmobile?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] truckerdewd:
2 numbers.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] truckerdewd:
From what I understand, unlocked will not get the update for the eSim option. I could be wrong but that is how I understood it.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] apatcas:
So in theory can I swap to an e-sim from Tmobile and then put another sim in from Europe when I travel?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] warriorvibhu:
If you are Sim unlocked (And have a t-mobile device & Service) then Yes .. I am going to explore if i can flash U firmware and get this feature
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] evnStevn:
I suppose if I flash build N986USQU2DUC8 using modded odin, I'd be able to access the

e-sim/dual sim feature by effectively morphing my factory unlocked handset (SM-N986U1) into the carrier-bound equivalent (SM-N986U).

I have to admit, I might give this a shot as I stand to gain something here, not necessarily lose! Sure, I'll pick-up a little carrier bloat, maybe a half-a-dozen apps in the switch, but that's it!?

It's a bold move, but a smart one, for T-mobile! When you pair that one with their recent commitment to Google for integrating the Google Messages app into their (Android-based)) system app line-up for new device offerings. They recognize the value of the upgrade to RCS messaging and what comes with that, for existing and new tmobile customers alike.

Sure, It'd be easier if this e-sim/dual sim feature was included in the SM-N986U1 OTA March Security Patch Update for the unlocked users, but their heart is in the right place and with their core users (SM-N986U) I suppose?

(I'm gonna give it a shot over the weekend...I'll be back!)🤔

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] VICosPhi:
It will work. I have done the same with my unlocked U1 :) This update made this phone the best phone out there and I have S21 ultra which is my backup phone lol
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] tx_dbs_tx:
I can confirm that the latest UC8 firmware for the unlocked U1 N20 ultra doesn't have eSIM support. I'm going to flash back to the U firmware for T-Mobile.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] evnStevn:
I'm fixin to get jiggy wid it, just after my f-ware d/l runs it CRC ck and decrypt, etc.

Tyme to fire-up dat engine, Odin, you know it! lol
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] evnStevn:
You still rocking 5G on da beast, after changing it's orientation? smh/lol

feeling large & in-charge 2-nite!🥳
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] evnStevn:
Hey bruh, seriously it may sound dumb, but I ain't been doing nothing with Odin since SM-N960U1 days but you know the old-skool rule of thumb to use your OEM issued usb interface, but our new boyz have the usb-c at both ends and all, so one of my hostages from a previous life the "normal" USB at one end, and usb-c at the other end will be right and tight, YES?!

PLS Holla bak youngun?🤔
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] evnStevn:
Probably...maybe eventually, but not til there's more of it out there meaning alot more wireless carrier support of it!

It's a bold move for my tmob, but soon we'll get the RCS messaging thru google's messages app w/tmob...that sh#*s tight!!

(my bad, Mod's....again, my bad)!🤢
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] evnStevn:
Did u get a chance to see my most recent post...the new bootloader Menu screen?!

What's a brother to.do when running in to that for recovery trying to flash w/odin?!
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dadmi:
Will we lose data by converting from U1 to TMOB U firmware?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] rjohnstone:
Yep... so backup your stuff.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] warriorvibhu:
Well this has to be verified, I have converted U to U1 and vice versa without losing data because i used Home_CSC. The new ones are bootloader 2, but this should still be valid. If you use Home_CSC you wont lose data. Feel free to correct me if there is any information i may have missed.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] evnStevn:
I tried this past Sunday to flash the tmob "U" firmware to check out the eSim feature for myself, and got shutdown in the process with the new bootloader Menu that pops up when you're hooked up to Odin and ready to flash...that's as far as I got, and I've looked everywhere on the web for advice on which selection to make on this new bootloader Menu screen!! So, I'll just have to wait it out and see if the eSim feature (and more to come I'm sure) will be made available for us SM-N986UI users?!🤔

(as true, historically, with most of these add-ons, "later" will be the result as opposed to "sooner" for the factory unlocked variant).
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] eelpout:
if I'm not mistaken (and I certainly could be), the US unlocked variant firmware is the basis for AT&T and Verizon's as well. So I wonder if they have to buy into eSIM first. If so, I'm not optimistic. :(
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] evnStevn:
Yes, when updating the o/s for their handsets, samsung only releases one (1) build for the factory unlocked variant

(SM-N986U1) regardless of carrier affiliation, which includes all carriers that offer/accept this model on their network. As I'm certain you know, there are several you didn't mention as they weren't needed to make your very good point!

I was just pondering, and welcome any feedback (or kickback), but are folks still paying extra for these unlocked flagship variants (like back in the day) where samsung added a line item upcharge of $100 to their invoice? Just curious, & would be good to know...🤔
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dadmi:
I used Home_CSC and it didn't work, Sim Card Manager was not present. Had to do start fresh.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] tx_dbs_tx:
Hey you need to do a factory reset first then remove your sim card from the phone. Download the latest T-Mobile firmware using Frija's windows application and use "TMB" for carrier code. Launch patched Odin (v3.13.1_3B_PatcheD). With the phone powered off, hold down volume up and vol down simultaneously as you connect the USB cable and it will automatically open your bootloader. Simply press volume up to connect and Odin will see your device. Flash all of the firmware parts and use the regular CSC, NOT csc home. It will flash successfully. Sorry if I covered things you already know but this is how I do it and it works. The thing to know is that you MUST remove your sim card when flashing to and from U/U1 firmware or else it will fail. Good luck.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] niijohnnie:
Thanks for the update. Yet to try it. However assuming you have done so, was the E-sim feature activated on the U1?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dadmi:
I was able to convert to U1 to U with TMobile firmware. Using Verizon physical sim and Tmobile eSim.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] niijohnnie:
Great heads up for the possibility of converting the U1 to have the e-sim feature. Thanks very much.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Fatmonk8:
Same
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] slytek:
I'm going to do just that, what would be best way to backup U1 (no root)? Its not all that important as i can just reinstall all the apps but i just wanted to know if there is a simple way to backup/restore entire phone with most if not all apps/settings intact after converting to U variant.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dadmi:
Smartswitch, Samsung cloud backup or Google backup.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] eng.abdul:
The question is. I'm an international user and don't have either US carrier sim and I've never had one. Is it still required to have a sim to activate the conversation from U1 to U or is the phone active and sim manager available prior to the sim installation.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] eng.abdul:
So I have done the convection today and before when I was on U1 I had only one IMEI also one was on the box only. Now the physical sim one is shown and another eSim the problem it is grayed out and the sim manager didn't showup. It still didn't change my CSC code it still shows XAA.

Can someone please support me I think I hit a dead end.

Update. I tried flashing it multiple times with factory reset prior without nothing worked I think I need a TMB sim to use with esim otherwise it won't switch my csc and activate the esim. I'm flashing it back to U1 and waiting for the update. This is extremely annoying from Samsung !
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Limeybastard:
Just in time for the party. Receiving my TMO note 20 U next week after returning my S21U. Was wondering how do transfer esim from one device to another? Is it 611 call
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Aseras:
I registered just to say thanks and that I FINALLY got this to work coming from a SM-N986U1, XAA Unlocked, from samsung.

It tried this and it failed so many times, or the esim IMEI was greyed out.

Here's how I got it to work.

Backup everything, you are gonna nuke the phone at least twice. Make Sure you are on U1 to start. Use Frija, get XAA CSC (U1) and TMB CSC (U)

as of now that's (U1) N986U1UES2DUC1. Extract it to a folder. Download (U) N986USQU2DUC8, Extract it to a folder.

Backup everything.

Sign out of ALL accounts. You are going to lose it all.

Remove SIM

Factory Data reset. Nuke the device. At startup screen, Reboot, hold down volume down and power and turn it off.

Hold Vol up and down, and plug in USB. Hit Vol up on dim screen to go to download.

Using Odin 3.13B Patched, flash all 4 U1 ( N986U1UES2DUC1 even if you are on U1, do it ): BL,AP, CP, CSC ( NOT HOME_CSC ).

Reboot. If it reboots to the red error screen, just choose reboot.

When you get to setup, power off, hold down volume down and power and turn it off.

Hold Vol up and down, and plug in USB. Hit Vol up on dim screen to go to download.

Using Odin 3.13B Patched, flash all 4 U ( N986USQU2DUC8 ): BL,AP, CP, CSC ( NOT HOME_CSC ).

Reboot. If it reboots to the red error screen, just choose reboot.

You should see the Tmobile splash screen. Go through setup don't connect to wifi and just decline as much as possible. You should get a tmobile TOS and Service crap page. If yes, you are good. Finish setup and verify that both IMEI are available.

(optional) Use ADB to clean up some of the crap..

Install SIM, It will do a carrier update.

Restore your data.

Yay.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] visualpro:
Hello,

I can confirm that the above method worked as well :) The model number reads SM-N986U/DS.. Also I T-Mobile hasn't updated to the latest security patch. Sstill at March 1.. The US unlocked SM-N986U1 had the latest May update plus the camera functionality from S21 (Dual video recording)..
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] eng.abdul:
Did both sim and esim work prior to installing tmobile sims?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Aseras:
Yes, no tmobile service required at all, just their firmware. If you don't wipe the phone to U1, then U with the Tmobile CSC the ESim and IMEI for it appear, but are greyed out and unusable and the sim manager is not installed. My phone still shows XAA,XAA TMB,TMB,XAA CSC for the Esim and Sim accordingly, and the dialers are not disabled, so all the csc change codes and service menu work.

I was able to extract EsimClient.apk from priv-app, but have not tried reloading U1 and sideloading it. yet.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] rjohnstone:
Won't help... the package already exists on U1 firmware, it's just blocked by CSC. restrictions.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] mlr_90:
OK. So I went from U1 to T-Mobile U firmware and everything went fine with eSIM support. Now..... I'd like to go back to U1 unlocked. Has anyone tried it? Did you lose eSIM support afterwards. I don't think I'd lose support as far as service. Just maybe the ability to add a second SIM.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Sword Fish:
I have tried this multiple times and cannot get sim manager to install. I see both IMEI numbers but esim is greyed out, physical sim is not greyed out. I also never see the tmobile splash screen. I have factory reset and installed the U1 software and even tried doing a factory reset again before installing the U software. Is there any way to side load the esim manager?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Sword Fish:
Wouldn't you need an original TMB sim in order to get your phone to download the sim manager? When I follow these instructions, it never downloads any TMB apps during setup and I am assuming because it doesn't see a TMB sim.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] rjohnstone:
You need a TMB SIM card in the phone to enable the software.

SIM Manager is already on the device, it's just not enabled for use. If you have a U device, the bloatware is built into the image.

Once CSC is TMB, the CSC code will enable the app.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Michael in ATL:
Has anyone else suffered reduced battery time since migrating to eSIM? I sure have.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] VioNeo:
That's very good news, knowing that you can swipe the physicals SIM to eSIM. I have all the updates and the eSIM option is there, however, I don't know how to swipe it. I have tried your advice, but I get no option to convert to eSIM on my Note 20 Ultra SD T-mobile. Any idea?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] radici:
I'm an international user... I also followed these instructions to the letter and have not seen the tmo splash, see both IMEI with esim greyed out... Biggest issue is though, then my data doesn't work at all, I don't even see a data icon. Had to flash back to U1 XAA to see it.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] JeffATL:
So still no update on Unlocked getting this officially? Also rumors about s20/s21 getting esim functionality with update but seems to never happen.

I am thinking of getting a Note just for this feature. Tried IPhone for dual sim but F it , I hate IPhone, I am a 100% Android.

The T-Mobile variant is $100 cheaper and will save me the trouble of flashing however it will be carrier locked. So will it be possible to use Verizon sim on physical if T-Mobile is on eSim if carrier locked? Is it unlockable with a paid service

Is it necessary to flash twice, seems like tx_dbs_tx didnt and got it to work?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] tommytep:
i tried again and again, follow exactly your steps but no success: the esim is still grey out, no tmb TOS and no sim manager. before flashing, my fone is on lattest June update. maybe Samsung has block the trick.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] JeffATL:
Which version of Odin did you use?

Did you try to follow this post?

https://xdaforums.com/t/note-20-ultra-esim-update-is-here-t-mobile-usa.4261933/post-84904131
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] tommytep:
yes. first round i did with 13.4 patched Odin, then again and again with 3.13.1patched as mentioned and follow exactly each step but still no sucess. Before flashing, my fone was on the lastest XAA june update. I even contacted T-Mobile to see if they can just unlock it for me but they ask for US citizent ID which i'm not.

Update: the only thing that different from the guide is that i'm downloading the FW from https://samfw.com with XAA and TMB version other that Frija because i cannot get it to work. is that make something different?

update 2: all the tutorial was all 2 or 3 months back and they mention first get back to U1 N986U1UES2DUC1 and then flash N986USQU2DUC8 over that one and I followed that process. Should I try with lastest FW update N986U1UES2DUE1? Havent try this one.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] tommytep:
Thanks bro. Will give it another try. What is your flashing procedure? from which base you're on before flashing to U?

update: still no hope. i've converted to U from latest U1 FW using Odin 3.13.1.3B patch, remove sim and reset before update. Please share details of your process.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] JeffATL:
I noticed on person posted they flashed twice but I did not see earlier in the thread where they said that was necessary. I would just try with the latest TMO firmware. You flash without sim but then did you insert TMobile sim afterwards? Not sure if that is necessary , would have to read through the 3/4 pages again.

I want you to have success because I have not bought the Note yet but before I do want to make sure it is still possible. I wish they would bring dual sim support to the S20 so I would not have to spend a few hundred to switch phones.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] radici:
What I'm going to try is... return to Bootloader 1 (Android 10 One UI ver 2) U1 firmware that still allowed the *#272 method of changing CSC. Switch my CSC to TMB, then remove sim and reboot to download mode, flash latest TMB Bootloader 2 Android 11 U fw. Hopefully I will see the TMB splash logo and such after doing that and all will work. If not, I shall just have to give up on this and revert to XAA U1 fw. Last resort, fingers crossed.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] tommytep:
Any updates?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] JeffATL:
Have you tried again or given up?

You cant go back to bit1 from bit2... once on bit2 you are stuck
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] JeffATL:
So what if you get a new non-carrier locked Note 20 direct from Samsung, will it be on bl2 out of box? And the follow up question of course , if on bl2, is there no way to flash to TMO firmware and get esim enabled?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] domhall012N8:
Very interested in this but... I don't see any firmware listed in the #1 post...
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] bigTINY779:

Anyone flash TMO rom on unlocked with BL2 and have success?

Thanks! Great news

Search one ui 4.0. The news is allover the place don't know how I missed it. Although looking like the beta for note 20 ultra isn't released yet just s21 series but it's safe to say the same applies to note 20 hopefully it stays on for the stable version.

Also the news is the beta is having some issues that might delay the stable release to late December early January. Let's hope we get it ASAP!
