I don't think an upgrade will work. Maybe the simcard is not OK.
Try that in another phone if possible.

That is to remove sim card restriction...
example
your phone provider is Verizon, and you want to use an Airtel sim
When your phone has a network lock, you cannot use airtel directly coz it is locked
When you unlock or openline your phone, you can use whatever sim card or provider you want

This is the first time i am looking at this problem,
but this can not be hapening.
each service provider has to give UIM card for the customer.
ask them,they will provide you UIM.

Thanks for help, but not work
cards may be old? I will order a 2nd copy?
any link with any tutorial to upgrade the firmware, is there any newer than mine?
Many thanks
my problem with my grand duos is. there is a network signal for both sim but. SIM2 can't able to send messages until I have to reboot my phone to fixed the problem. And this occurred usually every 2 days. I am just amazed is it happened. Also when I call in progress in SIM1 no sms arrived for sim2 and vice versa. After the said voice call the messages starts to arrived.
Hi,
I have a SM-j600FN and I know that the model for dual sim would be SM-j600FN/DS.
My doubt if the SM-j600FN have the hardware for support the second sim or somebody have converted to dual-sim? I searched but I have find nothing. My next step is buy the second tray for dual sim or convert my current second tray for accept the sim (the default cannot be used)
Update: I have installed a second sim and obviously the device/rom don't recognize

Thanks & regards,
I bought this J6 today and was kind of surprised it has dual sim for such a low price.
It has a tray for a simcard only and a tray for memory card + 2nd simcard.
Too bad i only have an old no (longer active) sim card as my second to test, but when insert it recognises the card and the provider shows up and when i want to make a call i get 2 phone icons and i can decide which simcard i want to use.
Thanks for your answer.
Could you say me the exact model of your J6 please?
I suspicious that my phone have a rom modified by my provider (Vodafone) and lock the second tray. I did the same test than you and the phone didn't recognize/detect the sim card.
Regards.

I have updated the rom via Odin with PHE rom and in SW's provider I see PHE/PHE/ATL instead of ATL/ATL/ATL and the second sim tray is not detected too. I guess that my hardware is not compatible with dual seem
some other experience?
regards and thanks.
Hello. I bought s21 fe but the strange thing that it's u2 model comes with binary 2 out of box and stuck at android 12 . Can I flash u1 model on it ?
G990U2 and SM-G990U3 : S21 FE variants with support for NFC, Bluetooth 5.0, dual-band Wifi and Wireless Charging.
so i think you can only flash G990U3 firmware ( U1 is without support for NFC, Bluetooth 5.0, dual-band Wifi and Wireless Charging )
Well, I am not absolutely sure about G990U2, but for S21, it is certainly possible to flash G991U1 to G991U. One of my friends did that (From XAA csc to SPR csc) and instantly got 4 pending updates till Jan'2023 one after another.

Incorrect.
U1 is simply the USA unlocked version. And they do have NFC, dual-band wifi, wireless charging, etc.
Could anyone share how you did the the conversion between U1 and U or U3 to U2? Im trying to do B2 to B on europien version.
