So, I picked up a cheap Tab 2 3g 7". Everything seems to work fine other than it refuses to understand sim cards!
When I put a sim in with it on, it does the "you must restart", but after a restart it still says no sim. Take the sim out, it tells me to restart...
I discovered if I just push a sim adapter in the slot it does the same, I think there's a microswitch that just tells the thing whether or not there's something physically in the slot.
Tried with three different sims, all working in my phone.
I was wondering - This tablet takes the old mini sim. Although the active pins seem to be the same between those and nano, could the Samsung be looking for continuity or something between the usually unused pins? Or perhaps some other electrical compatibility issue? The tablet's in pretty good condition, the slot feels fine, so I don't want to just assume this is a hardware issue.

Hi all:
I am hoping that there are some hardware folks out there that may be able to shed some light on my situation.
I have a 4G Xoom. I wanted to be able to use the same SIM card in my Xoom as my Razr Maxx, but the Maxx uses a micro SIM, so I activated a regular mini SIM in my wife's Spectrum with my phone number and tried the SIM in the Xoom and it worked great. I then cut the SIM down to micro size and put it in my Razr Maxx, again worked great.
I planned on using the remainder of the mini SIM card that I punched the micro SIM from as an adapter for use in the Xoom. I figured that it was a good idea to store the "adapter" in the SIM card tray/slot of the Xoom until I needed it...BAD IDEA! Due to the nature of the spring loaded contacts the "adapter" got stuck, hung up on the contacts. I thought that an easy fix would be to slide something thin in the slot to free up the adapter. It worked in so far as I got the tray and the homemade adapter out, but I must have pressed too hard on the back three contacts as they no longer made contact with a SIM card.
I took the Xoom apart and used a paper clip to raise the contacts back up, but I raised them too far so I went in again and still didn't get it right because although I had a signal on the meter I could not connect to anything. The third time was the charm. I got a signal and was surfing the web!
Now the strange/good part. I now get a full 4G signal (presumably because I am roaming on a non-Verizon tower) as opposed to the usually poor signal at my house. I live right on the edge of a Verizon 4G service area. The Xoom surfs much faster now than before I broke it, but why? Did I short something out? Did I fail to raise one of the contact pins enough? It isn't the SIM, I verified that with another device. I did something to the SIM card slot, contacts, or a related electrical component, but what?
I want to "break"my Razr Maxx and my wife's Spectrum also!
Thanks for any thoughts from any of you hardware guys or anyone that knows how SIM cards work. I don't even know what contact/pin does what.
Thanks

i look into but i see noting, how do you raise it up ?
(i make a mistake, push adapter without micro sim )

I did the same thing and I soldered extention on my sim tray. here is how I did it:

You should be able to take it to a local electronic repair man and have them do it, if your xoom is out of warranty.
Hi I have a LG optimus one (p509)
I was puttin in my micro sim adapter and it didn't fit properly. so I jammed it in,
Phone worked fine.
Then when I tried to take it out, three 3 of the four pins got caught in it, the sim wouldn't come out.
So I pulled really hard and now three of the four pins are sticking up.
So no sim cards (not even a regular full size sim card) would go through, so I thought maybe I could force the sim card down and it would work.
So I did that, now when I tried to remove it, it got caught again, so i took a screw driver and took off the thing that keeps the sim card in the slot.
(the metal piece )
Now half of the sim card slot is attached to the motherboard, and the other half is out.
So what do i do?
Can I just soder it back on and it will work?
--
My phone still boots up and is useable (just no service of course).
better have a technician repair it. i used to have a samsung (old model) the simcard is too loose so i soldered the sim pins (at phone) at yes!!! it failed.
I just got this phone today unlocked from tmobile and inserted my custom-cut nano sim into the nano to micro adapter and inserted it into the phone. Everything was fine for a while but i started noticing my data and signal was cutting in and out by itself when the screen was off maybe for 3 minutes or longer. This is a significant problem as you can imagine. I checked every single setting i could and nothing would make it do so. Any advice or suggestions? Im using a straight talk att micro sim card that i had cut down to fit my i5S but came back to android and used a noosy sim adapter. Maybe its the fact that the card is custom cut (so it already doesnt fit the adapter like its supposed to)? I really need help here. Yes i have the proper apn settings and im fully stock.

Hi all.
Received a supposedly new Galaxy S6 today and the seal was broken.
All seemed OK with phone so accepted it.
Put in a 3 sim card as phone is unlocked. Problem is it just says "Not connected to network" when trying to make a call. Though it has received 2 text messages and I managed to send one after the phone tried to send it for 30 minutes. Phone also isn't showing any data connection. It's been tried with the sim out my old phone and also with a new sim from 3 store today. Sim had been in phone for approx 8 hrs before I run out of ideas.
So the phone definitely works. Just can't seem to figure out why its not working properly . I'm thinking it likely hardware fault though would like anyones opinions or suggestions.
Cheers for reading the post

The new SIM card probably is not yet activated. Bring your S6 back to your telecom provider so they can test there with a working SIM. If it does not work then it maybe a hardware problem. Have them replaced your S6 if it is.
Sim was activated. 3 store tried it in another phone and it worked ok.
To make matters worse. I put nano sim converter inside Galaxy S3 to test my old phone. Couldn't get it out and bent pins inside phone DOH!
After leaving the store and arriving home my phone was showing full signal and the '3' symbol. Unfortunately would still not send a text or make a call.
My conclusion is that the phone isn't quite reading the Sim properly.
My decision now is to either wait till the seller replies(Who I don't trust) to numerous messages I have left or just send it off to Samsung for repair.
Cheers for replying

Send to Samsung for repair.
I've sent the phone back to seller.
I'm beginning to doubt myself though after this nightmare. This is going to be a long story....
When the S6 arrived I had to cut my micro sim down out of my S3 to nano size. I'm quite a perfectionist when it comes to stuff like this and did a good job. Though as the S6 didn't hold a signal I went into 3 store for brand new nano sim. Put it into the S6 instore and it was the same. Though they said wait up to four hours for it to register properly. Went home and after 6 hours still no luck. So I decided to try it in my S3.
This is when the nightmare began.
As I needed it micro size I cut out a template to put nano sim in. When trying to insert it in I wasn't happy. So I tried to take it out and the tip caught hold of the sim reader pins and came away. So I had a bit of plastic stuck in sim reader. Boy could I not get it out. So had no option but to buy a new sim/Mem card reader. Local shop wanted a tenner for one. Had no option so bought it along with a proper nano to micro sim housing and went along home.. Fitted it and then went along to the 3 store armed with both S3 and S6 to make sure I could either get the S6 working and if not get the sim put in the S3.
This is where my next dumb moments was. So I didn't lose the nano to Micro template I partially slotted it into the S3 sim reader.
Got to 3 store, explained S6 wasn't working with new nano sim and asked if they could check the sim was ok. They tried it in a HTC and it worked fine.
So this to me proved the S6 was faulty.
So I asked if they would put it into my S3 to show it worked ok in that.
So they went to put the Sim in my S3 and couldn't get the template out as i'm not sure if they pushed the sim converter all the way in!! As no sim was in the template the pins had hooked onto it. So ended up damaging the sim reader again. Jesus!!
So no working phone again. Just an apparent working nano sim.
Got home ordered ANOTHER sim/mem reader.
To get me connected I ended up taping the nano sim in place on the S3 and part of an old credit card on top so the rear cover put pressure on the sim as well. This was after cutting away the top part of the original sim reader to get the plastic out and to expose the pins. LO and behold it worked!!! Full signal just like I normally get and H+ data
So I've had a phone for last 24hrs working and got home tonight to find the new sim/card reader had arrived. Thought wow that was quick delivery. Took sim out and thought i'd give S6 one last try as I install the new sim reader. . Still no luck getting stable signal so boxed up S6 to return. Put sim into S3 with proper template AND you'll never guess what........ITS DOING EXCACTLY THE SAME THE S6 WAS!!!!
S3 now keeps dropping signal and going into emergency only calls. I'm thinking why didn't I just not touch it.
So is it possible that the 3 network throws a Dummy every time you swap sim into different phones??? Its just strange the S3 is doing excactly what the S6 was. Or could the S6 be upsetting the sim?
God i'm really baffled as there always seems to be more than one factor into the equation of whats wrong.
Now I'm just waiting to get hold of another sim to try or just hope after leaving my S3 on overnight it might settle down.
God phones....I hate em LOL
Just to clear up the Sim issue with the S3. Even though it was connected on the '3' network and not receiving calls. I happened to check the manual network provider list again and it was showing the '3' network twice in the list. Clicked on the one it wasn't auto selecting and S3 is working fine again. Tried the Sim in the S6 again hoping that may have been the problem also. Again the S6 manual network provider was showing the '3' network twice in the list....But unfortunately still didn't connect to network properly.
So S6 definitely going back Monday.
Anyone know if having your network provider listed twice in the network settings is normal? Or is it possible that '3' have not programmed the sim properly?
Cheers

Hi
I recently travelled from the UK to the US with a Galaxy S6. I'm on the Giffgaff (which piggy backs off O2) network.
I plugged my phone in to a US wall outlet with a travel adapter. I then when picking up the phone received a very violent shock (perhaps static, I am told), and the device was very warm. The phone now says No SIM inserted. However -- if I reseat the SIM card, it says 'SIM card added' and displays the 'Reboot' option. After rebooting the phone, no SIM card detected again.
I think, at least hope, this is software related, as it seems the SIM is being detected.
I'm running stock Android, and I've looked at the other, similar threads in this forum, but didn't find a solution. I tried " *#197328640#" and I get 'Not registered on network'.
Thanks

Did you solve the issue and how?
The phone was replaced as faulty.
