You can file a complaint there... AT&T rep got back to me after FCC contacted them.

They claim eSIM in the Note 20 series doesn't work with their system.

I told them that's utter BS since eSIM is an industry standard that all manufacturers use and if you can provision an eSIM on Apple devices, you can provision them on Samsung devices.

I got nowhere... oh and don't hold your breath on the S21 either.

Samsung's website claims it's active on all models, however the AT&T rep stated it will not be enabled on devices sold by AT&T's.

I wonder how much Apple paid US carriers to keep eSIM restricted primarily to Apple devices and a handful of Android Wear and Samsung watches.
[Samsung Galaxy Note 20 Ultra Questions & Answers] rjohnstone:
It's not. See my previous post. AT&T rep from the office of the President (AT&T) said it will "most likely" not be enabled.
[Samsung Galaxy Note 20 Ultra Questions & Answers] VICosPhi:
I want to believe in Santa! Taking screenshot of the product specs now so I can file FCC complaint if it lacks eSIM support. As for these phone reps and Samsung reps, they could be playing it safe this time by saying it doesn't have eSIM support, since last couple times they said it did and turned out it did not.

Take it with grain of salt but there seems to be someone in US that says he has eSIM working on S20 running U1 unlocked firmware. Link below:

I've decrypted the latest CTLB firmware and reviewed all the partitions and XML files. This includes decoding CSCFeature and CSCFeatureNetwork xml files.

Any mention of eSIM is completely removed from the device.

The second IMEI can be retrieved through the Diagnostics menu.

Did it once by accident and I'm unable to remember how I got to it. So the IMEI is viewable to the OS.

Edit... found it.

Looks like AT&T is being AT&T.

According to AT&T Website, no eSIM for S21 or S21+ (Only lists Nano), and the S21 Ultra lists "Trio" as the SIM type... why on earth would they list a resizable physical SIM in the spec?

The optimist in me wants to believe both Samsung and the carriers. Maybe unlocked S21s will have eSIM and Carrier versions will be single SIM.

Wow this is great. So if you purchased a physical dual SIM Hong Kong version of the Note you could swap the modem files to enable US LTE and 5G bands and have a dual SIM phone?! Do you need to root to replace the modem files?

in the optics of 986u1 in wwd csc it has ril_ support esim_false all the other csc are in binary and jarbled. but in features and network features it mention esim as false, I went through each one and wwd is only xml that is readable as plain text weird

side note esim client is there in your apps menu if you select syste. apps, also with quick shortcut manager under call settings it has esim profiles, remove all esim profiles , all of its there just set to false

on pre-order of my 986u1 I spoke to Samsung tech..not sales and I was promised dsds by esim and nano sim thats why I'm so mad as they lied... its in there one line of code to enable it

everyone keeps says carriers don't want it but if that was case why did fold z2 and s20 and iPhone 10 11 12 and so on have esim....they gave us shaft on 1500 buck phone and locked bootloader so we couldn't even do what we please with what we paid for

I'm tired of Samsung lies I will Crack the esim or die trying not that I even need it but its the fact they lied and when I crack it I will post for the world to have ,

on my 9860 I have 2 imei and digging around i found imei number 3 for esim but can't remember where I found it in my 986u1 google phone app ue menu is now disabled cand even do pre-config...the Jan 17 update killed it
[Samsung Galaxy Note 20 Ultra Questions & Answers] Mdyche82:
yes I have modded the files and have nearly every band unlocked and full 5g on t-mobile, it took hours and hours staring at my laptop in split screen fs file explorer open in both windows 9860 rooted in 1 window 986u1 in other can't modify 986 files but can still see system files

I want to decrypt a s20 or fold z2 modem files my biggest help was using Qualcomm net manager instead of Samsung I found in one ini file that disabled Qualcomm modem net manager set to disable and under it set samsung netmanager as enabled 0661 .

I have bricked and bricked and had to start over numerous times also even if you erase nand and cache there's still a resident file that shows every reboot and refresh reason mine is very vary very long lol
[Samsung Galaxy Note 20 Ultra Questions & Answers] Mdyche82:
second reply the hk is hybrid dual sim by default either 2 sim cards or 1 sim 1 SD card thats why I'm hell bent on getting my esim on. I carry 9860 with 1tb sd card for 1.5tb total ....in theory lol....477 and 910gb after formatting...lol but I want my work and personal numbers on same phone and still have option for SD card

they dropped SD card even from ultra s21 BTW its 2200 for 512gb version of ultra it might be able to use spen but no hole to stick it in and must be,purchased separately thats why I'm note user I use spen daily during work so I'd lose it if I didn't have hole for it

In my unlocked 986u1, I have esim client in system app. In my wwd csc, it has option of ril esim support set to false. I'll post pics later on. But I can't root it to edit.

Side note. I lost my uncrypted sx55m fusion modem bin file if anyone has copy...my had crashed with all my firmware on it. I had modified it to give me my 5g for USA on t-mobile. I have it as a .lz4 but don't know how to decrypt it to xml to open it.

Also. Android 11 eliminates Google dialer codes so now I can't even go into ue settings. I'm going to downgrade tonight.
[Samsung Galaxy Note 20 Ultra Questions & Answers] Mdyche82:
My nice 970 Evo plus ssd crashed and now I lost all my files, my cracked modem files. I'm so mad. I upgraded to 11. Lost google dialer to get into ue , lost my midded modem bin file. Going to try to downgrade.

If anyone has a sx55m fusion modem bin that's decrypted from .lz4 to just plain bin I would love it. Since Samford tool don't work it was only way I had to decrypt firmware files. In 7zip I just keep getting a lz4 even after decrypt. I will share if I can get into the file again. I had all bands on my 9860 that 986u1 has and CA 3dl . Gone. I am so passed at Samsung. It's hardware failure as I tried partition recover and the drive is dead. Only 6 month old. Don't buy 970 Evo plus ssd

I did manage to get my fusion config opened again and added the north American carriers , stock is only 4 options on 9860, rom-com,cu vote, chc, and something else.

As you see I have 18

I downgraded back to android 10, btk3 chc with magisk root.

If you have 9860 and want to add hardware modem files like mine, there's options for north America and Korea, China, South America, basically every csc modem is buried in the fusion modem files but not turned on.

I can post step by step if anyone wants to know how.

That sucks... I also have Evo 970 plus and this thing runs scorching hot. Gonna backup my data now. Samsung is releasing 980 Evo but as with everything else they have watered down the endurance of the new model which makes its lifespan shorter than 970...

I just bought a wd Gen 4 1tb nvme to replace it and holy crap. I'm only running it on 3.0 adapter but it's running 1 to 1.5 gb/s read and write. My laptop is only Gen 3 pcie if not I'd swap out my octane drive for it. It was only 199 at best buy

My 970 ran hot too. Even in metal case with thermal pads on it. It's hard failure. I can't even repartition it.

If you have Samsung 970 or 970 Evo back up now. I lost my son's immigration papers and tons of important stuff besides my root files

So far after months of trying, I have that set in optics and prism in my wedding csc it still doesn't enable it, I did manage to get all bands working though.

The files is in optics and prism folders...configs. but it don't work on 9860, there isn't lpa manager or euicc manager or esim client. The tgy and bri don't offer the wwd csc, and the customer.xml and network.xml in all other csc are in binary. Only wwd is in plain text. I've been working months on this.

What carrier/ country are you in. I can get you CA up to 3dl and carrier features by modification of the sx55 fusion modem file.

[Samsung Galaxy Note 20 Ultra Questions & Answers] rjohnstone:
No need for the caps. ;)

As for the eSIM function, it's just disabled in the firmware.

modem.bin has the feature turned off, but it can be enabled with a simple firmware update.

Of course you have to also enable access to the eSIM configuration functions in the carrier CSC xml files.

All of this can be done with a bootloader unlocked device with root access.

A modified modem file and carrier CSC xml file can enable the feature. But it comes at a cost of tripping Knox, no Samsung Pay, and other security functions that require Knox.
