Dual sim tray in single sim phone? - Samsung Galaxy Note 10+ Questions & Answers

I've got a Note 10+ 5G (SM-N796B) and currently have a second phone for work. I'd rather have just one phone, and as my Note doesn't support eSIM, I'm curious if buying a dual-sim tray will enable me to run both SIM's?
Will the OS (OneUI 3.1, android 11) automatically pick up both SIMs, or will it be more complicated than this?

dual tray will not make any difference

Dual SIM tray

Hey I see that you can use a dual SIM card tray... Where do you get them from ?
Thank you
Edit I have 5g version if that matters
Update - I have UK on ee 5g pro but SIM tray will only take one SIM it's not double sided.
i bought one from ebay
just search for oneplus 7 pro sim tray
I don't think the 5g model will take 2 sims. (Noticed your 2nd post so you presumably already know this )
I don't know if the 5g is dual SIM how can I find out? It has no settings in UI for a 2nd SIM
Anyone know if the 5g version is dual SIM... Two different people say two different things.
Regards
has anyone checked this out for the 5G version yet? might just order one and try it.
The 5G model can do dual-SIM, but you will lose 5G. You literally would have to flash it do a different firmware to achieve this or hope for someone to create a ROM with the 5G firmware that enables dual-SIM. The hardware is capable of dual-SIM, it's just disabled in the 5G firmware.

Due to arrive in 7 to 10 days.
Update: it works perfectly!
How did you get.it to work

A705FN to A705FN/DS ???

Hello, i have the sam A705FN (non dual sim varient, however other network providers here do have the DS varient)
When i took this phone i assumed i would get th Dual sim varient.
I see on my sim tray i have shouldhve had space for 3 cards (one last slot is blanked out)
Now my question is, if i get a ds varient sim tray will i be able to ise dual sim, even if i need to somehow flash the ds firmware.
And does the fn varient even have the hardware to support dual sim

all A705FN firmwares are for dual sim , exept on your device the dual sim is greyed out , you can buy a dual sim varient but tell me whats your country and service provider

I don't think you can use dual sim even if you used the tray form a dual sim model. If the phone only shows 1 IMEI number the device probably only has 1 sim card slot.

true but you can trick the phone by adding a 2st imei from another phone , also the firmware check of your hardware is compatible , so if it detect a dual sim it could theorically work and the settings would appear again or not be greyed out anymore

How can we be sure that there is a second sim card reader in it?

Yeah you can't be sure. My guess would be that it does not have a second sim card reader because it doesn't make sense for a company to make hardware and disable it through software (Even though it could and has happened). Cant be sure until somebody does a teardown comparison.

Hey, sorry for only getting back to you now, life has been busy..
but here's what's happened since i last posted.
I have an a70 from MTN-SA (mobile telecommunications network south Africa)
it is a single sim tray.
i used a sim tray from the Samsung galaxy a50 Dual sim variant, with no second sim detected unfortunately.
i wonder if the device has the hardware to support a second sim. If so, i do have an extra IMEI number to use that i got off a cheapo dual sim china phone.

i wondered the same thing.. But there is a dual sim variant of this device out in the wild.
My country doesn't allow dual sim (only with 2 specific carriers [cell-c & Telkom Mobile (8ta)])
so it's weird that they would make two separate hardware revisions for the same market?

Samsung Galaxy Note 10+ flashing

Hi All,
Can i flash my USA Tmobile Samsung Galaxy Note 10+ SM-N975U (USA) with SM-N975F/DS (Global) to activate dual sim functionality on my USA TMO phone?
As far as i know i need to replace the sim tray after flasing the phone with global rom to get second sim working as default sim tray doesnt allow you to fit second sim on the tray.Any thoughts on this?

No. They are two different devices. Even if you managed to flash F/DS firmware to your U, you would just end up with am $1100 brick.
And there's no way to "activate" the second SIM. It's not present in the U devices. Again, even if it were, there's no IMEI for it, so it would be useless.

Question If I use a duel SIM tray in my Single SIM (but displays 2 IMEIs in about phone)?

Has anyone attempted making their single SIM GP6 or GP6P Dual SIM just by changing the tray?
J/Wing before I order tray and find out....
V....1
The 6 Pro (and I believe the 6) are dual sim, its just one sim is an eSim, not a physical sim. Changing the tray will not make any difference as there is not 2 physical sim readers in the phone.

On OS's like LOS and StratiX I believe it reads 2 IMEI and 1 ESID for eSIM.
It should also be kept in mind that Google Pixels do not have "true" dual sim (sim/sim or sim/esim in this case), but "Dual SIM Dual Standby" (DSDS). So even if the in-built sim card/scanner would be replaced, that doesn't solve the software level limitation to DSDS (only one sim can be used for calls, and the other one for sms and vice versa).

Question Does the OnePlus 11 (U.S version carrier unlocked) support Dual Active Sims?

I'd like to buy a OnePLus 11 from amazon but does it support dual active sims? I'd like to be able to load balance my data between the 2 sims from different carriers. Is this possible?
Or combine the data throughput from 2 sims from the same provider. Is this possible?

Yes it does. You can use two physical sims or one physical and one esim. I use two physical sims. Verizon and T-Mobile.
As for how dual sims work in Android... You select which sim you want to use data one. You don't use data from both sims at the same time. Though, you can easily pick which one you want the data for.
Both will be able to send and receive calls and texts. Though you pick your primary/default sim for what calls and texts default to.
Thank you!, Now if I can just figure out rooting so I can get call recording going.
That's not dual active. That is dual standby. You won't find any phone with dual active sim in US.
Did you need to buy a dual Sim tray?
Thanks
Oneplus has 3 sim slots: dual nano sim tray and one esim.
Tried to dual esim and sim together but some reason on sim can do nothing but text can't use it for calls since I want esim for data
Well if u use esim and sim, sim can't be Verizon
