I just got a tmobile galaxy tab and when I insert the sim card in the slot, nothing happens. I heard it is supposed to reboot and then I will have a signal but right now it doesn't reboot and doesn't show signal.
I tried powering off and on but I still get just a circle with a line across on the top bar instead of a signal.
Is there something wrong with my sim slot?
hi
check if you inserted the sim card the correct way.
on my tab the mini symbol on the sim card slot doesnt equal the way the sim card should be inserted.
check the manual for correct instructions
edit:
i had the same problem at first.
inserted sim, nothing happend, turned it around nothing happend, looked in the manual, inserted it like pictured, and the tab rebootet and it works.
i dont remember how it should be inserted, and i cant look right now. sorry.
(excuse my bad english)
Same here. It lets you think you have put it in the correct way but if nothing is happening, chances are you have not got it in right. Flip it 180 degrees and push it in with you finger nail. The tab will detect it.
I did research to see how to insert and I have inserted it correctly (numbers and logo on top, gold contact on the bottom)
but nothing happens, it doesn't reboot, it doesn't show signal. The "mobile networks" in the Settings menu is greyed out.
I am going crazy here. What am I doing wrong?

did you inserted it with the "bigger" or "smaller"(the one where the corner is cut) side first? ( sorry but i dont know how to describe it ;-)
i checked mine, you got to insert it whith the chip facing down, and the "smaller"(cutted) side first.
hope it helps!
yes I did that. I inserted with the cut piece first and gold contacts on bottom. It is the only way to insert it and fully go inside.

My unlocked 8525 quit recognizing my SIM card this morning. It says "SIM card is missing, You can still makle emergency calls if your service provider supports it." The SIM card works in other phones, so it's not the card.
Is there any way to make it recognize my SIM card again? What went wrong?

Also..
I noticed that when I slipped the SIM into it's place, it kind of bends up a little. I didn't think much of it, and figured I hadn't noticed it before, but I got to thinking...so I tried putting it in again, and then the battery, and I sort of squeezed it together to compress the SIM down and then started the phone. It worked! I had a signal, and I called my home phone to confirm. And then as soon as I let go of the pressure it died again.
After looking at the space that the SIM card fits into, I couldn't see anything that would make it bend up like that.
Any help???
Post some pics if you can, many eyes might see something that one set may not.... also you could pm Mike Channon and see if he has any ideas, but without seeing, my guess is as good as yours (and Mikes is as good as everyones combined). Cheers...
Hi all,
Just got home, looked at my mobile and it said there was no signal - so I turned it off and back on again, then it said there was no SIM inserted. Keep restarting the phone, keeps saying the same thing. Why?!
Am going to try it in my old SE K850i to see if it's the SIM card or the phone at fault.
In the mean time, does anyone else know of this fault and how to fix..?
I didn't the drop the phone or anything, it was just in my pocket, on it's own - like it always is!
Cheers
Tried it in my K850, works fine. Please someone help
yeah i usually dont put the sim card all the way in but slightly in and it works
I've re-opened this thread due to me misreading....DOH! Apologies (Mental note to one self.......follow own advice and read before posting).

you could try to clean the contacts on the sim card connector of the phone with a q-tip, and see if that solves the problem.
also check if any of those contacts appears to be bent or something, and so doesn't make a connection with the card.
Everytime I open the back up to remove the SD card, I get the SIM card missing bit even though I have not touched it! My HD is only 3 months old and it has done this from the start. I just have to remove it a bit - shove it back in and the phone accepts it is there. Annoying but not enough for me to send it back.
hmm, maybe try to make the sim a bit thicker so it doesnt move around (it shouldn't move by removing the back cover, but it seems to happen on your phone / sim combination.
try putting a thin piece of paper on top of the sim (not the contacts side, but the side facing to the battery cover)
maybe that prevents this problem?
Missing simcard
I have the same problem with my simcard. Though something strange happens when the phone is off for more then 10min, it works fine and notices there is a simcard for like 30 sec after which the error pops-up again. I have tried all of the above things, my simcard works fine in my other phone, adding some paper to thicken it doesn't work either
Anyone who could help me with this?
P.S. sorry for the bad english
As in post 7# written, put some papersheet in the simholder above your simcard to increase the contactpreasure. This surely helps.
Tis trick is also useful for all dualsim users who thik the dualsimadapter does not work in their device (but after using this trick get astonished!)
for Thysiey:
Try to switch to Gsm mode to test . Maybe you have bad umts signal? Happens at other places too, or only at one place?
Got the same issue here...
I cannot move the SIM because it is being hold in place by the battery. (to little room)
Adding a piece did not work either.
Anyone got another solution?
anyone? My mothers HD just got this problem now. She has a new phone and for the contract renewal she had to read the backside of the sim. The phone all of a sudden didn't recognizes the simcard anymore.. I tried a few other simcards but it won't read it anymore.
My plan was to sell the old phone but now it's almost worthless just a shame it is still a great phone to operate.. handy with the navigation and all
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.
I just got an Axon 7, and everything seems to be working well. But I set up the "scheduled power on/off" option to shutdown at 3AM and reboot at 5AM, and so far (2 days), the phone has been showing "no sim card" every morning. The first day, a manual reboot detected the sim card. Today, it didn't. After powering down and reseating the sim card, it was detected, but I don't know whether the reboot did the trick or the reseating.
Anyway, does this sound like a hardware or software issue? Anybody else having it?
Happened again this morning. A manual reboot brought it back again. I'm going to disable the 'scheduled reboot' option and see if that 'fixes' it. But it doesn't seem to be a hardware thing, since most of the time, a manual reboot detects the sim. Could it just be done dodgy timing issue in the boot sequence. I'm running the latest B27 US build.

Okay, it's failing hard now. 4 reboots in a row with "no sim card". So I tried the card in my old phone - not detected there either. Can a phone fry a SIM card - because it looks like that's happened.

LG G3 here - half the time after a reboot, it gives me the same SIM card error. After which of course i need to reboot it several times before it will recognize the sim card again.
This looks like a hardware fault, probably a bent pin in the card reader, so i carefully cut off the cover of the reader slot with a dremel + small cutting disc, being very careful to leave the sides of the cover to hold the card in place while it's in - it doesn't seem to be the case, everything looks fine, and from the markings left on the sim card by the pins as you remove/insert it, looks like all the pins are contacting the points on the card itself.
Also very weird that it ONLY happens right after rebooting. The most probable scenario i can think of, is that the card is read on bootup, and not interacted with again during normal usage of the phone...? or maybe a glitch with timestamps? A few times, restoring the backup of EFS partitions "seemed" to fix the problem, but :/
so.... WTF??!?!??!?
Was it a used or new Axon 7?
If used, someone may have had an SD in with the SIM and damaged it.
I was running mine that way but was careful and it survived ok.
Have you tried the SIM in both positions as 1 or 2?
Also ensure it has a correct APN saved against that SIM.
UPDATE: (LG G3) Seems it's a software bug after all. I updated to a newer version of LineageOS, and out of 6 times i just rebooted to test, the "no sim card" problem occured once. So maybe it's not 100% solved, but at least i don't have to futz around for 30-40 minutes to get my phone working again after a reboot.
My mom just got this phone yesterday and in the notification bar it says 123456 on the left side. I have done some searching and not seeing anything about it.
Does anyone know what this is and how to get rid of it?
the left side should only be displaying what carrier the phone uses. try turning the phone off and re-seating the SD card. also, make sure you have the card in the 1st slot, as this phone is a dual sim setup.
