[Q] 7.0 Plus: Sim or MicroSim

Hi guys,
Just taken delivery of a Tab 7.0 Plus 3G version (it looks like it is from Hong Kong, but I don't think that matters) and I can't work out if this takes a standard SIM or a microSIM.
The cover and the manual refer just to "SIM" however I've tried to put a standard size SIM card into it and whilst it fits width wise, I can't close the SIM card cover because the SIM is too long, and the phone doesn't recognise there is a SIM inserted (if I force the cover closed, it caused the SIM to be released and it pops the cover open).
But, my understanding of a microSIM is that is it both shorter and narrower. Given that my full size SIM fits width wise I'm not sure if a microSIM is right and therefore totally confused.
If I hold the SIM card in with my nail (before the lock pushes it back out slightly) the tab say "Sim inserted, reboot" however after the reboot it still doesn't recognise there is a SIM.
Anyone got any thoughts or suggestions on what the tablet needs?

OK, complete muppet moment on my part. I was trying to insert the SIM the wrong way round
So to assist anyone the SIM contacts face away from the screen and the diagonal cut corner goes in first.

Micro SIM to full size SIM adapters for G2.

Has anyone used a Micro SIM to full size SIM adapter with a G2 or G1?

The reviews mention a reference to it working in an HTC Sensation and an HTC TITAN.
Problem: My new phone (Samsung Galaxy S3) uses a Micro SIM. But I still want to run my old G2 or even the G1 as spare/backup phones. For when I go somewhere I don't want risk damaging the new phone. Once I move my account over to the Micro SIM, the old full size SIM will be dead.
The T-Mobile guys at the store said they would re-program a full size SIM from a micro size SIM, but I don't want to have to go down to their store just to do that!
And cutting a full size SIM down to a Micro size SIM isn't going to help me go back and forth.
I know it's only a buck for this particular adapter, but I don't want to wedge something into my G2 that's going to not work and mess it up. That's why I'm asking if anyone has had any good or bad experiences dealing with this yet.

Well the SIM slot is basically quite simple there's real nothing to snag onto as you're just making sure to face the contacts towards the phones contacts and just sliding past them. With no vertical room to move (only horizontal in and out that has next to no wiggle room) I double very much you could actually damage the phone with said adapter.
This however concerns me: "Simply cut the GSM sim card to fit the adapter (please make sure you do not cut the metal contact.)"... if you go thru with it, I recommend using a razor blade like in those house blade assemblies, instead of scissors.

For a free micro sim adapter, order a giffgaff sim below as it comes as a microsim inside a normal sim so you can either use the new sim or use it as a template to cut your old sim to size.

When i went to t-mobile to get a replacement sim (the old one started to bow and didnt always make contact) they duplicated it for me, and gave me both the old one and the new one, saying if it ever stopped working right that the old one would work still. Why not got ask for a new one? then you have two sims that are functional, you can have one full size and one micro ?
i know you want to avoid the store but it might be a simpler solution

I use a micro sim card in my desire z without any adaptors. I just slot it in where a normal sim should be and it works.
But it's a bit fiddly

So do I, perfectly working

I have nano SIM and adapter, working without problem

S7 Edge Dual SIM + SdCard Mod

A genius idea!
Someone found S7E indeed can read Dual SIM with SdCard running at the same time.
So simply peek off the golden part of the SIM and stick it to a SdCard, then put it together with another SIM onto the tray. Magic happens! :good:
Is there any gladiator brave enough to try?
If this works, if definitely will buy a S7E!!!

This is an old idea and much popular between Huawei Customers as they always lauch these type of dual sim phones and i also tried it on P8 Lite

Can you tell us More? I'm waiting for my SD card to arrive and do this. I already practised on a broken sim card and I could fit it into my phone and out

It works on my S7E bought in Hong Kong. A bit tight pushing the tray back into the phone as it does add a tiny bit of thickness to the SD card. In fact so snugged that I haven't got the guts to take the tray out again!

Thanks for the feedback. I actually tested a broken SD card and sim card. I used a hand file to smooth the edges and it worked very well. I'm ready to go now.

tested working on S7 Edge Singapore. 1 Main SIM and roaming sim with microsd card.
I wonder if any brave user from this thread tried to eject again the sim tray with the microsd/sim2 mod?
tried it once since i put a wrong sim card on SIM 1. a bit tight, but after it pull out using the sim tray pin, i just pull it carefully. I just remember how my sim tray was stucked on my htc one x because of the microsim i cute with a little thicker than newer sim card. cannot be pushed by the sim tray pin anymore since the button inside is stucked.

I just tried to use 2 SIM card with a brand new evo+ 64gb SD card on my s7 edge dual today, I burned my 2nd SIM card and took out the chip from the sim card, glued the chip on the back of the sd card that I have sanded down. THE RESULT WAS DISASTROUS. I ENDED UP WITH A WRECKED SD CARD AND AN USELESS SIM CARD = 40 bucks down the drain :crying::crying:

why the FFF would you do that? burned the Sim card? you already lost that. Sanded down the SD card? you broke that too.
you should not slim down the SD card AT ALL. the upper layer of the SD card is just a paint on the board.
you should cut out the SiM card carefully and don't damage the small part in the back covered by a drop of glue. then slim down that drop of glue carefully and stop before you hit the small board inside.
then carefully cut the side a little before gluing it to the SD card. then try to smooth out the corners and sides VERY carefully to make sure while pushing in and pulling out it won't stock somewhere.

I found this tutorial video on YouTube and was going through with it step by step. However it suggested to use an sandpapaer for thinning down the sdcard i didnt have that so i used the filer of the back of a nail clipper instead :crying: anyways I don't recommend for folks to try it unless you've got some spares sdcards and SIM cards lying around.

i did this successfully without burning or heating the sim card. what i did is just trim down the side of the sim card until the gold portion remains and until there is a little separation gap is seen from the gold module to the plastic. i removed the plastic part by a very thin cutter on the edges until i can fully pull it out on the plastic. removed the dried glue from the sim chip and taped it on my microsd card.
i didn't use also a glue to do this. I just used a very thin double sided tape. put small portion of tape on 2 sides of the sim only. i didn't put the tape on the middle chip area so that the thickness still minimized.

even though i'm waiting for my 200GB micro SD card, i just told my brother how to do it, and he successfully did it. 128GB SD card and 2 Sim cards are working on his phone now.

the only thing with running dual sim, 1 sim only runs in 2g... not many carriers support 2g anymore.. lolol

it's only for s7 edge dual sim variant, or work fine in single sim also?
i want to do in my g935f

You need a dual sim phone.

did not work
my uncle just returned from uae with the dual sim version s7 edge....I myself have a uk model s7 edge, using his sim adaptor with the 2 sims I put it into my uk s7 edge did not work!
any suggestions

I think u will need a dual sim phone to be able to use two sims.

It's not just the sim tray that is different. The electronics inside the phone to read 2 sims are only present in the dual sim versions.
Question though, have people successfully pulled out this modded sim tray without damaging the cards or phone?

The electronics are identical, there's a dual sim reader in a single sim phone, problem is you only get one imei.

Tried it once. because the first time I inserted the modded microsd, i inserted also a wrong sim on sim 1. I have no choice but to pull it out. the microsd didnt and sim tray didnt break. but it is a little more tighter than without the modded microsd card. I think it will depend on the thickness of the microsd and how you glued the sim chip to it. if you glued it too many, it might be a little thicker.
Just be careful not to push the sim tray pin to the hole too hard. it might be stuck and the tray cannot be pulled out anymore. tried it on my htc one x before. I cut a old sim to microsim. since it was an old sim, it is a little thicker than the newer microsim. i pushed the sim tray pin to the hole too hard and it got stuck. good thing i can pull the sim tray by fingernail. but this will not happen on once it will be stucked on s7 as the top portion of the phone is flat and cannot put anything to pull it out.

Micro SIM to Nano SIM?

I have a phone on order (HTC 10) that takes a Nano SIM (4FF). My current HTC One (M7) has a Micro SIM (3FF), but looking at it, it appears as though a nano SIM (4FF) could be broken out from the Micro SIM (3FF), much in the way that many mini-SIM cards (2FF) can "break out" to become a Micro SIM (3FF).
Does this sound possible? I hope it's not too confusing how I have tried to posit the question. I'd like to be able to transform the micro SIM to a nano SIM when the new phone arrives without going to the T-Mobile Store.
Thanks.

I don't think you can because with a micro SIM the contacts come almost completely to the edge, trying to go smaller would compromise the contact area. Go to the store, there's a right way to do things and a wrong way to do things, engineering an alternate solution is only necessary when none already exist, in your case, alternatives exist.

This may help

Take your chances and trim a micro SIM to nano size but I'll wager you'll have issues and have to get a proper nano SIM anyway. The correct SIM shouldn't cost you anything from your carrier if you're paying for cell service on their network. Why complicate it?

Dual sim options?

I have an unlocked Samsung Galaxy S7, (not edge) G930U that I purchased on ebay. I foolishly expected that since I was buying a flagship phone, I would get dual sim cabability. I was clearly proven wrong. I have however seen a hack that showed that an additional sim can be added, by removing the metal bit from the plastic and glueing it to a micro-sd card; and placing it in the micro-sd card slot in the single sim tray. I tried an alternative route of purchasing a proper dual sim tray from a mobile phone store; and this didn't work. It fit perfectly and sim 1 and the micro-sd card worked perfectly; but the mobo wouldn't regcognize sim 2. The theory of the hack being that the S7 mobo is already internally hardwired for dual sim, it's just that this feature has been hidden or deactivated.
So what I'd like to know, is this hack just BS, or do I simply have the wrong phone? Does the G930U mobo NOT have dual sim capability. It might also be a matter of critical dimensions, that were met with the hack but not met with my method. Pehaps the dual -sim cicuit pads are there on the mobo; but the contact fingers are not; which is why forcing sim 2 down a few 1/1000s, by glueing it to the 'bottom' of the micro-sd card works. And a nornal two sim tray doesn't. Any insight appreciated.
Can I just take this phone to a mobile store and have them crack-it-open and add the fingers, or replace the mobo? Sure, I can replace the phone, with a dual sim edge; but they're kind-of delicate and kind-of suck, especially if you have to repair one. Besides, I got a great discount by purchasing a refurbished one
SiMORE
has several 'add-on' options available; but I don't like any of them. I don't want to have to add an attachement or carry around an extra box. I just want my 'flagship' phone to be dual sim. This just makes sense in a 'mobile' environment. If you need to use Uber or Taxify and your carrier isn't performing as needed, in that location, you need to have a sim 2 (second carrier) option, period.

To my knowledge the US models never had a duo variant, they have a different SoC with a different mobo that has no hardware support for it.
While it is true if you have the international model you can hack it to see 2 SIM's since it's the same mobo as the duo, it means you have to falsify or steal an IMEI for the second SIM to use, which is illegal and you won't be allowed to discuss it here.
You can get a G930FD which is the S7 flat (not edge) international dual SIM model with the Exynos SoC, but the US doesn't use this model so your network compatibility may vary.
