Which Format of Sim Card?

Someone can confirm which type of Sim card will be sued by the G3?
I saw a device comparison which indicates that G3 will use a Nano sim? :silly:

I have no confirmation or anything but I'm pretty sure it'll be nano sim, why wouldn't it be?

Because other phones used microSIM

Yeah but others used normal SIM cards, doesn't mean anything...keeps moving forward. Nano is much more compact and it'll probably stay that way for a while now.
I suppose at this point it might definitely be a 50/50 but there's no reason to assume that it won't use nano, iPhones and HTC M8 already use it, so the newer devices might use it too.
Can't see how it makes a difference though, it's pretty fast and easy to get the right sim card. If it's an upgrade with contract they'll give you a new sim card, if you have a micro sim it's easy enough to even cut it down to nano on your own, then again...any outlet might do the same and/or provide you with a new sim card.
I got my nano for the HTC free of charge because I'm still on contract! :good:
We'll see though, almost time

Dual sim tray in single sim model?

I'm going to be traveling internationally in a few months, and more than likely going to end up on a local SIM where I'm going for while I'm there.
On the single SIM tray there appears to just be a spacer molded into the tray where a second sim would go in the dual sim version. I'm thinking about ordering a dual SIM tray from China on eBay (10 bucks) so I can use the second sim slot in the tray as storage for my not in use sim.
Anyone know of any reason this shouldn't work? I can't think of any reason it shouldn't...

You'll have to flash a dual sim firmware package but there's issues with flashing firmware that's not what originally was installed on your moto z play.
You could ultimately loose your IMEI , Which would render your phone useless.
It's just easier to sim unlock and insert a single sim.

I'm already sim unlocked (have the US unlocked version courtesy of republic). My intention is to only use whichever sim is in slot 1. I'll manually pull the tray and switch sim positions when I need to switch. I just want the second slot as dead storage space for the unused sim card. Just wondering if there's something physical in the guts of the single SIM version that could be damaged by or cause damage to the unused sim in slot 2 of the tray. Or if there's something physically different about the dual SIM tray that will not allow it to fit in the single SIM version of the device.
Definitely no flashing of dual SIM firmware happening on this device.

You should be fine. Just make sure that the active sim goes in the same slot as where it would go in the single-sim tray and the inactive sim go in the spare slot. It's a good way to not lose a sim card. I was thinking of doing this for my single-sim, carrier variant Moto x play, but never bothererd.

Thanks. Avoiding losing a sim while on my trip is my primary reason for doing this. Guess I'll give it a shot!

Update:
Received dual Sim tray from China today (13 days order to door, $10 shipped on eBay)
Visually compared both, they seem basically identical, with the exception of some type of serial number sticker on the original single Sim tray.
Fit isn't quite perfect - the angle of the outer piece of the tray isn't quite right, so it's a tiny bit recessed into the edge of the phone on one end, and slightly raised on the other end. Enough to be visually noticed if you're looking for it, and can be felt running a finger nail over the seam between the edge of the phone and the Sim tray. Don't believe it's enough to present any "catch" issues if running naked, and a total non issue if using a case or bumper.
No apparent functional issues - device connects fine using Sim 1 slot in tray. Did not feel any unusual resistance when inserting tray with both Sims aboard. Obviously doesn't see the Sim in slot 2.
Nice to be able to carry both my Sims with me, worry free. Worth the money for my use case.

16 years old sim card on Galaxy-S9

Hi
how can i use my 16 year old sim card (micro-sim (3ff) and a nano sim (4ff) in the Galaxy-S9 ?
so is there maybe any adapter to do this ?
thanks

I don't believe so. While the slot 2 is large enough for a micro Sim, I believe it wouldn't work. Slot 1 uses a nano Sim and slot 2 either a nano Sim or micro SD card. The SD card is oriented one direction and the Sim is oriented a different direction in the 2nd slot. I've never seen an adapter that would make the nano sit sideways in the 2nd slot and I doubt that old micro Sim would trim down that much without cutting into the metal. Surely your carrier will replace the old card with a newer all-in-one Sim.
Maybe the folks that have a dual sim phone will have more of an idea on this.

Hi @Tel864
I thought maybe something like that for S9:
https://www.amazon.com/UTP-Universal-Adapter-Extender-Android/dp/B07C7G35L6
where i can attach this in the sim slot and put my micro sim extern
any idea
thanks

I've never seen that. Something like that may work but I'm not sure about that one since it's for a different brand. When I searched for Galaxy S9 Sim card adapter in Google I did get lots of hits so you might try that. The one you posted is from a 3rd party seller so I'm not sure how easy it would be to return.

If you look at the different sizes of sim card, full sized, micro and nano have the same pin layout, it is just the plastic borders that differs. It could be a bit risky but you could cut the plastic edge off and make them into a nano sim without any trouble. I've done this and it works perfectly on my s9. Don't know if the chip under the contact pad is bigger on older sims though.

People have recently been reporting those adapters being recognised by the OS and rejected with a warning about a problem with the SIM Tray
Why not just get the SIM card replaced with a Nano SIM?
Or trim it yourself if the chip itself is small enough

Might work, but some of those old Sims had a larger contact area, especially those 16 year old ones like he has.

Dual sim and SD card simultaneously

I live in Europe and thinking about getting the G8s (we only have this version). Did anyone try to use the dual sim+sd card hack that you have on samsung phone? Cut a sim, polish it down and glue it to the bottom of an SD card. Then you can use two sims and and sd card simultaneously. One can also use a sim extender to achieve the same result.
Samsung implemented a software block on this since android pie, not sure if LG has the same.
Thanks in advance!
edit: it does work. Just tried on a phone.

Please post instructions so I may try this....

could you let me know how you got the DUAL SIM to work? what settings/software/app's you had to use? I'd like to make it work thru factory software if possible
THANKS,
MS

Question Dual sim tray disabled in software (SM-S901U1)?

Hi all,
I recently purchased a Galaxy S22 (SM-S901U1 - S901U1UEU2AVF7) from Google Fi with the intention of using 2 physical SIM cards and 1 eSIM on it.
On Samsung's website (https://www.samsung.com/global/galaxy/galaxy-s22/specs/) it says some models have "two Nano SIMs and one eSIM".
Upon receiving my S22, I took out the tray and noticed it could only fit one physical SIM card, however, looking at the sim card slot through a stereo microscope it looks like there are SIM card contacts on either side of the slot (meaning the physical connection is there).
Also, doing a `*#06#` shows IMEI1, IMEI2, and EID; which to me signifies the phone itself could support the "two Nano SIMs and one eSIM" option.
I went ahead and bought an S22 replacement SIM card tray with support for 2 SIM cards, and put another SIM card on it but can only see "SIM 1" and "eSIMs" under "SIM card manager".
It honestly looks like Samsung disables the second SIM card in software for the US market.
Can anyone here confirm my suspicion and if so, do you know if there is a way to change that software restriction? Thanks

The second IMEI is specifically for the eSIM, the EID is what one would consider the ICCID if it was a physical SIM.
Only models outside the US have the option of a dual physical SIM.

Thank you for your response.
Do you know if that is a limitation imposed by hardware differences (i.e.: the US version is missing a radio or SIM card slot) or is it imposed by software?
(I have purchased a dual SIM tray to put into my S22)
If it is the latter, would flashing a ROM from a region with support for dual sim cards (and the same processor) enable dual sim cards for the S901U1?
Cheers

I wouldn't know if the hardware doesn't support it.
If I had a guess, it would probably be locked at the baseband with software, similar to the OnePlus 9 Pro. The latter was later confirmed by users; even though the hardware was the exact same across all devices of that model, changing to a different ROM changed nothing as the baseband retained its state.
Also, most if not all non-US models use the in-house Exnyos SOC, so finding a stock ROM to determine this would prove difficult.
Someone might take a poke using QPST and other diag tools. I can't currently do so myself.

Hello TS! Do you have an update here?
