[Q] Problem inserting SIM in Galaxy Tab

Picked mine up Contract Free from PCWorld. On Wifi it works great. But, I have a really stupid problem with inserting a SIM in the device and getting it to stay in.
I have tried inserting both a giffgaff PAYG and a Three PayMonthly SIM (full size)following the directions in the booklet and watching a couple of YouTube videos.
With screen facing me, insert SIM with gold contacts facing down and cut out notch on lower left. If I hold the SIM card, the phone will reboot and I have network connectivity. However the SIM will not stay in place even with the slot cover in place it comes free. There is no reassuring click when I insert the SIM card, I have tried other ways of inserting the card, there is a click, the card is held in place but the phone does nort recognise a SIM has been inserted. So I'm pretty sure my method is correct.
Help, Im at the pointy of taking this one back. A quick search on XDA and google does not reveal any meaningful results.
Regards,
Mike

Cut out notch is on the top left...look at the picture on the SIM card slot...

I keep my finger nails short, and I found that I could not insert either the SIM card, or a micro-SD with my fingers. I needed to push down on both with a pen.
Hope this helps.
Dave

I did have this problem of the tab not recognising my simcard when I first inserted it. I was sure it was done correctly.
Try taking out the sim card and rubbing the chip with an eraser. Clean off the residue before inserting it back. You may still see no service after the phone has rebooted. Be patient n wait for a while more. The signal will come. This solved my problem. I hope it helped you too.
Sent from my GT-P1000 using XDA App

pushing the SIM in with the tip of a pen has done the trick. I guess my fingers were just to fat!
Thanks
Mike

Nah, I had the same problem too and I have thin fingers, solved it by using a business card that was next to me
You just need to use your nails for these damn cards / slots, and mine are always too short to do the job.

Hmm
As I figured out today, it's obvious when the sim is in correctly, because it goes in much deeper and doesn't look anything like it might obstruct the closing of the "flap".
I had to use a long nail to get it in the correct way round (did it while the tab was on) and as soon as it was in the tab detected it and rebooted itself.

[Q] How to eject a stuck sim tray?

Hi there,
So I just received my Nexus 4 today, the first thing I did was cut my normal sim --> micro sim so I can use it on the nexus 4. I was successful in doing so and my phone is working perfectly. However, the problem i'm having is I didn't trim down the thickness of the sim card, and now my sim tray is stuck (unable to eject with the ejector tool). It does "try" to eject cause I see the edges pop out a bit, but not enough for me to get a good grip to fully pull it out.
Since the phone is working perfectly, I'm not really in a rush, but it's just annoying and for the future of getting new plans.
What should I do? Call Google for a new phone for my fail or will mobile store be able to help me?
Thank you.

ohh wow. I suggest using a tweezer or a needle to pull the tray out. Once out, GET A new micro sim and put it in.

Took a break last night from trying so hard to get it to eject. So this morning I tried again, the 2nd time it managed to eject just SLIGHTLY more that gave me enough grip to pull it out. Afterward, I sanded down the back of the sim card to make it thinner, then insert it in again, test multiple time carefully to see if it'll freely eject. Works perfectly now.

Just walk into a T-Mobile store to change your sim card. It's free and in some cases, older sim cards will have problems with newer phone.

Sim card not recognized?

Just got my 6p(!) and it doesn't recognize the nano sim I put in. I put it in so that the chip itself is facing down. Does anyone know a fix other than restarting the phone?

same happened to me
I thought i was the only one, i have to send mine back...and i live all the way in Jamaica!!! this totally blows!!..Took forever to get it to me and now this!!!

The SIM should only fit one way, because of the shape. Here are some photos of how the SIM card sits in the tray.

It's in that way and it doesn't work

I hope I don't have to send it back, I've only had it for about an hour!

Have you flashed a custom rom? I unlocked mine time as I got it and flashed Chroma and Pure Nexus and got the same error message with both installations. I finally figured our that I had to download and flash the same vendor.img that the custom rom was based on to get the sim recognized. I have never had to do this with any other phone. If this phone is different somehow, it would be good for the devs to include flashing that partition in their zips or provide info about flashing it seperately.

No I didn't flash a custom Rom.. I got it unlocked bootloader and then the day after I put sim in it when I got the case.. (Didn't want to use without a case) put sim in.. Nothing.... Wiped data... Nothing... Flash factory image.. Lock bootloader... Nothing nothing nothing!!!

I'm going to try activating the sim. I thought it was ready to go since I only ordered one due to the nexus using a nano sim instead of the micro my gs5 uses

well i'm happy for you ...suxx for me...i'm back to being the only one with his problem!! smh....#FML

I had flashed the the newest vendor.img and then made a backup.. When I made the backup I choose to include vendor.. Then I flashed a couple of ROMs but I wanted to go back to my nand and restored system, data, VENDOR etc.
The issue was that I restored the vendor.. Flashing the vendor.img again made my simcard issue go away

Well I returned it and got another one.. Received it today and all is good now. Thanks for your imput

Nexus 6p no sim error
After a week with the no sim error issue I suspected the sim tray shorting the sim card ,after taping the edges of the sim card that sit on the tray and putting it back it worked immediately. I then removed the tape from the sim card and applied nail polish where the sim card sits .
After it had dried I put it back and I had a signal !

This! Mike you're an f-ing genius!!! I just received my 6p and less than 24 hours in, I received this SIM card error. As I was preparing to RMA it, I found your post. I pulled the SIM tray out and looked at it with the card in it. I'll be damned! There's about 1/64" overlap of the card contacts onto the metal tray. Short-circuit city! A couple of small pieces of scotch tape as an insulator and, Boom!, all is well! I can only imagine how many 1,000's of 6ps have been returned for such a stupid issue. The fix took all of 2 minutes. Thanks again!

Photo?

And Btw...the issue is somewhat different in my case the signal comes and goes in every 10-15 minutes or so automatically sometimes comes for 5min and goes for hours. But after the signal loss it sometimes shows "No Service|Jio4G" and sometimes "emergency calls only" in the Network Tile in Quick settings.. But reboot/ toggling airplane mode temporarily fixes it. Did you also had the same problem or was it a permanent signal loss in your case ( I mean even no reboot/airplane mode fixed it) ???
And also no calls/msgs work while there is the signal...
Any ideas what's happening in my case? I've heard few same problems and few guys got it fixed by repairing their IC from working phone.

My nexus 6p doesn't recognize my sim card after 7.1.2 update.
Some way to fix it or is it a hardware problem?

Cleaned SIM contacts? Put tape on the back of the SIM to improve contact? Go to your cellular provider and ask for a new SIM at no charge? Complete wipe and reflash full stock image. If it is still unresolved then yes. It is hardware.

What can I use to clean the SIM contacts? And SIM Contacts mean my Sim card or the sim hardware inside my device?
Where should I put the tape to improve contact? My Sim card doesn't keep stopped in the tray, if I touch it it just move.
I have wiped but I haven't my pc right now to flash stock.

Use a good quality pen or pencil eraser on the gold contacts of the SIM and wipe clean with alcohol or dry cloth. Apply tape to the back of the SIM opposite the contacts. This is to push the SIM closer to the wire contacts in the phone. The SIM should be held very tightly by the tray and not move around. If this doesn't work, go get a new SIM from your carrier. If all the above doesn't work, then wipe the phone and reflash a full Google image using flash-all.bat SIM tray pic here.

Well, my SIM doesn't keep held tightly by the tray. It moves even if I just touch my finger at it.
@edit
Can I use alcohol to clean the golden part of my Sim?
Then I just dry and insert it to test?
EDIT 2
My sim is working perfectly on my Shamu. Forgot to mention this.

This is exactly my Sim tray. The contacts (Golden part of the Sim) faces down when in the tray, right? My I just turn the tray facing down (the Sim down) the Sim just fall, so it's not being held by the tray.

IT CAN ONLY GO IN ONE WAY- NO, it does not LOCK into place so you can turn the tray upside down, but only will seat correctly in one orientation then you slip it into the phone. Are you kidding me?

Not a SIM card issue.
There are possibly some settings between 7.1.1 (or older) and 7.1.2 that cause both a SIM issue and/or a Bluetooth issue.
If you have Magisk installed you might be able to fix by disabling any installed modules and wiping the cache.
Reboot and see if things are normal then re-enable the modules.
I saw this problem when I updated my phone without a complete wipe of the data (not SDCARD) partition.
If you have Magisk, try the module solution first.
Otherwise backup your data and do a clean install of 7.1.2,

I noticed that my device imei and my Sim tray imei are different. Maybe the old user changed the device's imei or something like that. I'm trying to recover the imei via efs professional. I'll try it as soon as I arrive home.

My phone detects sim but shows no service... It detects and shows signal on jio....can anyone share efs plz so that I can try to restore efs partition...

Just came from the tech and he tested the antenna. Everything is working great with the antenna. Anyway, I can't get any signal. He said maybe there's a problem in the SIM slot, and he showed me that the 6P is dual SIM
He told me to try finding a dual SIM tray and put my SIM in the slot 2.
Someone have any idea about what to do with it?

Fixing no sim card detected and no service

Dears
Facing the problem of no service and no sim card detected on my v20 after a reboot or randomly ,i ve tried every thing and found out that the problem is coming from the sim card reader ,there is a space left between the sim card and the reader causing the problem ,the fix is to full the space with a small paper or something to force the sim card into the reader

I know this is a necro post, but I wanted to confirm that this DOES indeed work. I got a second hand V20 from eBay today and couldn't get the thing to recognize the SIM Verizon was giving me at all. Gotta go back tomorrow to have them activate it now that I know this trick works on this phone!!

I ended up sending the phone back for exchange, after a small 1" drop the SIM was dislodged and the adapter broke and got a new one which didn't have the issue, so I unfortunately don't have any pictures. The best way however to place it is to ensure that it is directly over the SIM card and goes into the slot with your SIM, it should be providing some pressure on the back of the SIM to push it into the slot firmly, but not bulge the MicroSD adapter's metal too much, if you've done that, a fall may just break your SIM reader.
