I only have one SIM slot in tray. Can I swap it and make my phone DUAL SIM? - Samsung Galaxy A70 Questions & Answers

I know A70 is dual SIM. However my 705W variant only has a 1 SIM slot. The 2nd SIM slot tray is covered with a plastic. If I switch my SIM tray with a 2 SIM tray will my phone become dual sim?

yes you could try grarak modified lineage OS build which unlocked the 2st sim card slot , but you could have bands related problems.

But even if it's unlocked via software, can it work without hardware modifications? I mean, do single sim models have a second sim reader inside?

You are asking about hardware modification.
Maybe you can get one of those microsd card + simcard combo module from alibaba.
Couple with it modified firmware, and maybe it would be possible

Is is possible to convert samsung A70 single sim to dual Sim SM 705w model?

ZS570KL form TIM - not working SIM2

Hi,
Please help.
I am the owner of the new ZS570KL but when I wanted to use it after inserting two sim cards detects me only SIM1. I have tried on several sim and only continue to detect SIM1.
Will this feature be included as in Lenovo?
The Asus Zenfone 3 Deluxe Tim branded is a single sim model due to hardware limitations. There isn't written "sim 2" on the sim card slot in fact

XT1789-06 UK single SIM to dual SIM

When I bought the XT1789-06, I thought it's a dual SIM version, since there is a lot of webs with specifications for XT1789-06 saying it is dual SIM.
But it looks like XT1789-06 can be both. Dual SIM and also single SIM. Mine is, unfortunately, single SIM, so I am thinking how to change it. The SIM slot inside the phone has pins for two sim cards. Problem is that the tray holder is only for one sim and one micro sd card. So I am thinking to buy a tray holder for two sim cards. Something like this: ebay.com/itm/Dual-SIM-Card-Slot-Holder-Tray-For-Motorola-Moto-Z-Force-Droid-XT1650-02-Black-/172710907197
The question is if I would also have to change the ROM? For which version?

For your Z2 Force, do you put two nano SIM cards in a SIM-and-MicroSD Card Slot Tray Holder?
How stable is SIM #2's signal and reception?
Which XT1789 version is your Z2 Force?
Thanks!

Samsung J6 (sm-j600fn). Ready for Dual SIM ?

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.

Dual sim support N975U

It's my first post, hi everyone!
I was wondering whether it's a hardware thing and it's not possible to achieve dual sim support by modifying the software and replacing the N975U single sim+micro sd tray with the hybrid dual sim+micro sd one or it can be done.
I've got the unlocked T-Mobile N975U version, non-root, full stock.
I'll appreciate your support.

AFAIK the SM-N975U does not support dual sim. Has only a single SIM card slot. Changing just the SIM tray does not change the built in hardware on the mainboard.

N9750U Dual Sim !

anyone try to put dual sim tray (hybird one) and change the software to any oneUi from other notes 10 + versions which support dual sim ?
