Actually my phone is locked on t-mobile and I bought unlocking service and imei repair too the guy who unlock my phone flash 2 imei on my phone . He messaged repair imei1 done and imei 2 done . I was shocked how can he flash 2 imei on single imei device its new to me I'm a senior member here and I know samsung is selling it as a single sim phone for s21 fe . S21 has dual sim option one physical and one esim . When he flashed 2 imei then It's still displaying single imei on it when I check *#06# . I flashed U3 firmware on it to change my csc XAA . When I flash U3 android 13 my phone started displaying 2 imei on the phone and both physical Sims. I orders sim tray to test it is it really working or not I wait 4 days to get the sim tray when I got it I tested both sim cards are working fine

That unlock and repair cost me around $175

Thank you for the info. I also get another sim tray for my device but unfortunately it only has one imei even the firmware is marked as G990U1/DS. DS stands for dual sim but it is not working. Maybe my device does not have physical second sim slot

How can I do that? I have tried to flash U2 and U3 firmwares but those have different binary and the flashing failed from start. I am still on G990U1/DS

You have G990U1/DS and no dual sim support? On G990U1 you cannot flash U2 or U3 .

Could you refer me too? I'm trying to unlock my s21 fe from metro. Thanks.

You need a cpid service which is quite expensive. Like $200 can do carrier unlock and dual sim functionality too

Possible SIM Unlock from your carrier

Hii to all
Now I have to say something for most users who have bought it
over some carrier on contract like I have done
I asked when I was buying K5 PLUS are all sim slots locked to the provider I bought from?
She checked it for me on paper and said, yes, the phone can only be used with the carrier
SIM cards only and that was for both slots...
Well I was lazy to check when I got home if she was right or wrong...sometimes they do
not have the right information
But today after QFIL and after i Installed the firmware with QFIL
I tried a different carrier sim card in the sim slot 2 and it works
Both cards works
Tested so far..
So, maybe a try for someone locked to some carrier..
Good luck with flashing and just do it exactly step by step all of
you should not have any issues

LG G7 single sim, possible use slot SD for sim2?

Hi guys, I own a lg g7 thinq - single sim. Is the hardware the same as g7 double sim or not?
Can I use the sd slot to insert the second sim? I dont want to use at the same time, I want to be able to switch at sim1 to sim2.
It's possible?
​
PS In my slot sim space for the sim2 is visible

No.

Exactly, if the limit is just software maybe there is a way to activate the second SIM reader... or not?
I remember that the mate 10 pro (single sim) was unlockable via software.
PS I dont need the second IMEI, because I dont want to use the sims in same moment

Samsung Note 10 Modelcode

Hello,
what Version is this Note 10+ ? Is it Simlockfree Phone ?
SM-N975FZSDVD2
Thanks
It is an international exynos 1 sim model, tje model code is what you already wrote, or what exactly is what you want to know?
Its an German Vodafone 'brandet' Phone, branding is so far I know only a start apk by vodafone, it should be simlock free.
Open Germany Version shoukd be DBT in the last three characters
Yes, it is a simlock free german Vodafone Phone. There is only the Vodafone Start App on it.
I heard about activating the phone by doing a at least 10 minutes call with a local simcard.
Do i still have to do that before i put a non european sim card into the phone ?
We have a german Telekom and a USA t-mobile simcard.
Thanks
Yes, you need to use local sim card for around 10min and then you can put whatever other sim you need. Remember that if you have a dual sim then you need to activate both sim slots with the local sim card first

Enable eSIM SM-G981W?

I bought a Canadian variant Samsung Galaxy S20 (Snapdragon) yesterday, and knew that the SIM reader slot was faulty and needed to be replaced. I had assumed that I could just use eSIM, but didn't realize that the Canadian variants have it blocked.
Any advice on how to enable it? Can I maybe flash international firmware onto it to have the SIM card manager and enabling of eSIM, and if so, which one and how? Using Odin? Or a modified Odin? Do I need a working SIM reader?
Or maybe I change the CSC? If so, any instructions on how to do it with my variant?
Or do I need to root? If so, any instructions on how to unlock the bootloader (I don't have the OEM unlock option in Developer Options) if I am on One UI version 4.1? Or do I need to downgrade? If so, how do I downgrade?
I really don't want to have to tear this phone apart and resolder on a new SIM reader slot. It's a really great phone and the nicest one I've owned.
I'm not sure where to start.

i will
I read that if the W model is flashed with the U1 firmware, Samsung Pay can no longer have Canadian credit cards added. Can someone verify? OneUI 5.1 is being tested on the S20. We can only hope Samsung enables eSIM for that release.
W model has 13 release now. Does it still not support esim?
I was on the U1 model Android 12 in Dec 2022 (With esim enabled) and updated to the W model Android 13 firmware figuring it should have esim enabled however it did not.
I used odin to switch to the Android 13 U1 firmware but it did not enable esim (I used the home_csc). I flashed the older U1 Android 12 firmware which did enable esim again but I had to factory reset the phone due to a boot loop.
After reseting and doing an OTA update to Android 13 the esim stayed enabled and I restored a backup using smart switch for my apps and settings.

So in summary, to get eSIM in A13 U1, first odin install A12 U1, and then OTA to A13? The A13 U1 was uploaded yesterday ( link ).

It may work if you use csc instead of home_csc which would reset the phone straight out. I used home_csc which kept my Canadian firmware settings and likely csc

Does Samsung Pay work with Canadian credit cards in your A13 U1? That's the only requirement holding me back from converting. Samsung Pay+Google Wallet cover 90% of the places I regularly shop at.

I only use google wallet so I never tried samsung pay before. I installed samsung wallet and seems it wants a us zip code.
Ok guys so i bought Samsung Galaxy S22+ in Korea. I am from Europe. Reason why i bought phone in Korea was it was like 20% cheaper then in EU + it have Snapdragon instead Exynos.
But as i came back home i was in for a suprise, coz i tried to set up dual sim for the phone, but then i realized i cant do it. SIM card tray where u put physical SIM cards have only 1 SLOT, 2nd slot that was supposed to be on the back side is slighty modified so SIM card cant fit in, also there is no writing SIM2 like its written on fron (SIM1).
Also phone doesnt have support for eSIM, i cant open SIM manager or anything related to SIM cards in settings of my phone.
Dual SIM is important for me coz i use 1 SIM for SMS and phonecalls, its my number, and 2nd SIM is for internet. We are able to buy internet SIM here that have 60GB of data per month and its super cheap, like 7 EURO, so running dual SIM is super cheap version. If i buy internet via my regular phone providers where i can use phonecalls and SMS combined, it cost like 3x more.
SO yeah, i mean i could go for more expensive version and just have 1 SIM but its stupid coz 1 of reasons was i bought that phone is to run it DUAL SIM, i have also my old Huawei P30 pro working just fine, and now i feel dumb for buying another new phone that was meant to replace my old and its not working 100% correctly...
Can i modify my phone to make it work? Install EU version of Android or something? I would rly like to make it work, although even if i make it work i am not sure if my Internet/Phone service provider support eSIM so i swap this main physical sim with eSIM and then use internet one as physical. But ill deal with this later. I just wanna try enable eSIM first if its possible and have dual sim support in my settings.
Any help is very appreciated!
Best regards!

Question 990U1 firmware with wrong csc after repairs

Hello all. I had the WI-FI toggle issue where the Wi-fi simply would not turn on. All measures were taken and finally a local Samsung authorized repair agent had to replace the motherboard which did fix that issue. But I have the model listed in the thread title but the repair shop flashed the 990U firmware on the phone upon return home. I should have realized a red flag when the repairman asked me which carrier I had because they were having an issue with the firmware taking hold. When I got it home it had firmware from November 2021 and it would not update any further.
Well I took it back and then they actually got the 990U1 part right but this time it had the wrong CSC version on it (Tracfone) XAG when I mentioned that mine was carrier unlocked upon purchase so I would want XAA. The agent said Samsung only provided them with the one they put on it???
Now there are differences between the CSC versions. When the software is released being one I have read. My current carrier is LycaMobile so would not a firmware version of XAA be ideal as that is what was provided when I originally purchased the phone and what I had requested or possibly Tmobile as that is whose towers my current carrier will use. Doesn't it also matter as possible future ESIM support and band support could be different depending on the firmware correct??

To change csc samfw is a free tool which allow you to change it for free
I recommend to remove sim card first .
I think s21 should support esim . I have s21 fe G990U2 and it's was locked on t-mobile . I took it to the repair shop they unlock it and after the repair I flash G990U3 on it and now my phone has 2 imei and I can use 2 physical Sims on it .

I also have the S21 FE G990U2 (MetroPCS variant). Did the OEM unlock option appear in developer options after you flashed it? I would want to un-brand my FE after I unlock it to (CSC XAA?). I would be using Mint as my carrier (T-Mobile).
No there is no oem unlock option in the developer options. It dose not support esim too . Both physical Sims are working .
