Dual SIM support - Samsung Galaxy Note 20 Ultra Questions & Answers

I'm looking for a dual SIM note 20 ultra, only want an unlocked variant. I've read about e-sim and T-Mobile but I'm ok with dual SIMs but wanted to ask specifically which models for US have DS? I want to order directly from Samsung but have read where some people say they have dual SIM, others do not. Thanks.

T-Mobile released it a few months ago & the at&t update enabled it today

Thanks, I'm more interested in straight from Samsung with an unlocked device. I don't like carrier phones. I'm guessing no e-sim or dual SIM direct from Samsung as it looks like it's an added feature by carriers.

Going to ask again, do all unlocked Note 20 Ultras have dual SIM? Samsung says they do but I could swear I've read here and elsewhere they do not. Went to pull the trigger and just today says they no longer offer the 20 Ultra but can still get it refurbished.

one plus 7 pro tmobile dual sim tray and same imei for both slots

I bought a oneplus 7 pro from someone through offerup
i had an old samsung j7 that had dual sim functionality that i need for work and productivity so when it came time for an upgrade i bought the oneplus as it was advertised as a dual sim phone by the guy who sold it to me.
at the time of purchase, i just opened the settings and saw that it had two sim settings (sim 1 and sim2) and i naturally assumed that it was a dual sim phone.
i also plugged my att sim and figured that it is unlocked. i also did a factory reset and there was no branding for any carrier when i started the device.
therefore i just assumed that this is the unlocked dual sim version.
however, once i got home and tried to put the two sim cards in it and i quickly realized that the sim tray can only fit one sim.
when i called oneplus support about this, they said the phone is designed as single sim and that it was a tmobile phone and thats about all the info they gave me.
i went to tmobile store and they confirmed the phone is unlocked and paid off but they wouldnt help
me any further with the dual sim functionality.
upon quick google search i found a dual sim tray for the phone and ordered it. it is arriving today. I am thinking that all i have to do is just install the new dual sim tray and have dual sims working.
however now that I am looking at the settings more clearly i see that the imei for both sim slot settings are the same.
i checked the firmware on the phone and it seems that guy who sold it to me installed the nonbranded firmware but i am not sure if it is still the tmobile branded firmware. Does the Tmobile firmware startup with the Tmobile logo? how can i know i am running the latest international firmware ?
are the imei numbers the same because it is still on the tmobile firmware?
the build number it reads is 9.5.11.GM21AA
Also, if i pop the two tmobile sims in it, will the device be blacklisted simce they both will have the same imei?

You are running international firmware.
The software is strange and just like the 6T it reports only one IMEID.
If you put in two SIMS they will have different IMEID.
Look in the forums for threads on T-Mobile converted to dual sim.
Thank you for the quick reply. The dual sim trey will arrive today so I will try it and report back.
Thank you.

If he is running a T-Mobile op7 that has been converted to International then he only has one IMEI. That same IMEI can be used in both Sim slots but you were wanting to be careful if you're using the same provider for example and an mvno that is on T-Mobile and then a second Sim that is also on T-Mobile although T-Mobile is one of the few that is pretty relaxed about duplicates. If you're on something like AT&T you'll want to pay a lot more attention.
If you are using two completely different Networks then you should not have an issue.
I know this works because I am using a T-Mobile version that was converted to International myself with a dual SIM tray.
If when the phone boots up you see that T-Mobile logo then you were still on the T-Mobile software. On the international version you'll see a little Android droid logo at the bottom and a OnePlus logo.

Hi,
New around here...
Any idea on how to unlock a T-mobile locked One Plus 7 Pro?
T-Mobile says I don't qualify for unlocking as I'm the 3rd owner and not having a T-Mobile account and SIM.
Any advice on this would be greatly appreciated as I'm going to inEurope for a while and need to insert local SIM cards for better rates.
Many thanks
Cris

How unlock used Samsung Galaxy Book 2 (Verizon) so I can use T-Mobile SIM??

How unlock used Samsung Galaxy Book 2 (Verizon) so I can use T-Mobile SIM??
My friend bought a used Galaxy Book 2, put in his t-Mobile Sim and message came up that stated something to the effect that his device needs a Verizon Sim. Even with this message (as someone said it still worked) it did not get a signal.
He cannot return this as he bought it from some 3rd party he will never see again.
He has T-Mobile as a carrier for quite a few phones and has some sort of lifetime extra device -T-Mobile sim plan he can use so he does not want to move just this device to Verizon.
The question is can this be unlocked by Verizon store? And even if it is and APN settings are changed would it work with a T-Mobile Sim?
I know nothing about these LTE laptops and not sure at least for Samsung if the radio in it is somewhat universal or compatible with most US carriers.
Thank you for any advice.
I appreciate it.
Sincerely
Peter

Verizon Note 20 Ultra

Hello guys,
Yesterday i bought a Verizona Note 20 Ultra supposedly unlocked, i put my sim from another carrier and it worked, when i got home i saw the following note in the screen: "Your device cannot be activated on another carrier at the moment, contact verizon support". My question is, Can i flash a unlocked firmware in order to use another carrier sim?
P.D. I have tried with T Mobile, Cricket and Telcel sims and non of them works.
Thanks you guys!!
You'll have to get in touch with Verizon so they can rectify it. If that doesn't work you can try an online sim unlock service to see if they can do anything about it.

If the device was used/activated with TMobile, is fully paid and you have a receipt or invoice twitter/facebook tmobile support will unlock with no other questions asked. I have unlocked 5 devices in the last few years. Unlocked S22 and S22 Ultra last month by chatting on facebook messenger.
Not totally relaed: If the phone is unlocked, do any US carriers support eSIM + Std SIM config to help me use one phone for two lines?

Yes, only if it is unlocked model. For carrier models after you have unlocked the phone, esim is a pain with other carriers. Verizon system doesn't provisione sim correctly for a tmobile branded S22 Ultra. The Verizon reps have to add the device to their system for their system to provision esim. I tried with many reps for close to a month and gave up.
I had similar issue with Note 20 Ultra and Verizon were able to provision after I escalated many times in January this year but no luck with S22 Ultra. It may be a Samsung thing where they are not sharing the device details of all models with all carriers to add to their systems for esim activation.
