Which Dual Sim Adaptor to get

Hi Guys,
I'm looking forward to buy a dual sim adaptor which preferably dosen't require cutting of sim cards and is durable.....that leaves only one type of dual sim adaptor which makes copies out u'r SIM cards and puts it on single sim card like this 12 in 1 Sim Adaptor
However, this type of adaptor isn't compatible with some sim cards, So is there anyway of knowing before hand weather my sim card's can be copied or not?
Let me know, if anyone has tried this kind of adaptor..
Regards,

[q] xperia m sim issue

Hi
I recently purchased a Xperia M Dual Sim model. Unfortunately I did not know that it was a micro SIM. Now I already have a Nokia Lumia 520 with Micro SIM. The one in Lumia was cut locally by mobile salesaman. The dimensions of the micro SIM was not exactly as per specifications with it looking more like a Nano SIM with all the plastic edges trimmed out. Now this one works fine in LUMIA but as I insert them in Xperia M , it gives error NO SIM.I have carefully seen that the 6 connector points in SIM matches with the 6 quadrants in the SIM but no avail and tried multiple times in both the SIM slots of this dual SIM model. When I look carefully I see that the SIM slots in xperia may have a switch mechanism in the bottom of their SIM slot which detects SIMs which are not cut properly or are not of the perfect dimensions. Is it true for any of the guys over here. Pls help cos otherwise Id have to thing that there is a defect in the SIM Slot.I have checked in both the slots and they are the same.
Thanks
Saboo

Well, first try with a micro sim. They are not expensive and you don't need to change your number or something.
You can't be sure if you only try with hand-cutten not matching sims.
Try with a new one first and then you can see if you really have a problem.

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.

you can use dual sim if you dont use SD cards. there is a way to use dual simcard plus SDcard. youll have to search for it in youtube.

pretty much useless then...i saw that method it sucks, you have to cut and glue the sim to the sd card

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.
