[SOLVED] No SIM card... Emergency Calls Only

For some reason that is beyond my comprehension my TAB has decided not to read my SIM card anymore.
I just flashed OC 3.0.1 Wipe, with the modified P1000N kernel the same as always this worked perfectly. I rebooted and lost 3G, I rebooted again and lost SIM card recognition.
I switched SIM's at home, SIM works on other phone, got a new SIM at work, same problem. Somebody suggested an /efs problem, but I reflashed everything from scratch and nothing changed.
Any other suggestion?
EDIT: Ok it's fixed. Bent SIM connector in the TAB I guess I'm lucky I have a service Center at work.

Good info, maybe someone else facing the same problem can use this info.

That's really worrying me. I've had this happen often myself, and wouldn't like to pull it apart to try and unbend the connector.
Wonder if there's an easier way to fix it, or at least work around it (though jamming some paper behind the other side of the SIM card will probably only make it worse eventually?) Don't know.

I have just came across this same problem, the tablet knows a sim card has been inserted, probably because of the spring mechanism, but it nevers asks for the Pin Code and always indicates No Sim Card.
Can anyone tell me how many "Connecters" are in the sim card slot. With a strong light I can barely make out 3 close to the entrance and possibly 4 connecters further in. ( Their placement is strange though as it appears that they wold not match up with the Sim Card ( I could be wring though).
I don't not want to try and pull the tablet apart and therefore I too would like to know if it might be possible to bend the connectors, does anyone have any idea how I might possibly proceed.

Nexus 4 not recognizing sim card

I printed out a template and cut my old sim card from Rogers. It's activated and the back of it says HSDPA.
I have tried inserting the sim while my phone was off. I turned it on and it still said no sim card. Do I need a new sim card?
One side of the gold chip touches the metal tray. Does that make a difference?

I chopped my tmobile sim card (from G1 days) and the gold chip was larger than the replacement sim that I got (G2X). I popped the newer sim into my G2X and activated. Then removed and used the template to chop and it detected immediately one placed in the tray.
Sounds like you need a newer card to me.
Hope this helps.

Yes you need to get a new sim card,
The problem with Nexus 4 sim tray is that it's metal and not insulated like iPhone 4,
This also was the cause for data drop on my side, I had my sim card replaced after my first one just completely not working anymore. And just so it won't happen again, I took a thin piece of paper to cover part of the sim card just so it doesn't touch the metal tray on both sides

My card was cut and seemed top work fine until it sit if popped outs place one day, took it it and grinded away the edgy bits that the cutter left behind so it was smooth and got nicely into the tray. Benn working ever since (fingers crossed!)

No sim card error

I have the ATT Galaxy S4 and it's been great, but lately it randomly has No Sim Card Error, and askes me to insert one, the only fix for it is taking out the sim, and putting it back on.
Anyone having this problem?

Can you provide more information about your phone?

How long have you had the phone for?
I read on another forum, back in early May someone with an S4 also getting the No SIM Card error.

Is your phone modified in any way? Root? Customs roms? Etc. Perhaps there's a problem with your sim card. I would start with that.

it is running a custom rom, but it happened with stock touchwiz also, im trying the tape method, hopefully it'll fix it.

Try getting your company to exchange the sim card and if issue still happens just replace the sim tray yourself unless you got an insurance plan that covers free defective hardware or ship it off to samsung for repair.
Here is a link to a sim tray for the s4 that I bought for someone to repair their sim tray.

alright thanks, ill try my tape method first, and if that doesnt work ill do that.

Please insert SIM emergency calls only
I bet I have more experience with this than anyone else with a Samsung Galaxy S4 for AT&T 16 GB
This hand set was run over by a large SUV and I was amazed it survived and kudos to otterbox.
Since then, I've been having this SIM error as well, at random. I see it reported that pulling the SIM out and putting it back in was the only thing that worked, I'm glad simply rebooting works for me, so I don't have to peel apart the otterbox all the time.
I tried the tape and it didn't fix it so I replaced the SIM/SD card tray. The new part on Amazon cost me $14 and the YouTube video showing the operation of peeling these things apart was helpful. I didn't see a video in particular about how they're glued down but I managed to peel the original SIM/SD card tray off, scrape off the adhesive that was still stuck on the motherboard, and install the new SIM/SD card tray.
I still get random SIM errors. No change. Putting a layer of tape on the SIM chip was easy, replacing the tray was difficult, and neither one of these efforts to fix it worked.
My SIM errors are the definition of random, I get one error right after another in just a few minutes, or it will stay lit up and working for hours.
So I put my wife's SIM card in there to make sure it wasn't the SIM itself making the problem. She's never had a problem with her SIM in her Note 2. Guess what, she let me use her SIM in my S4 and it wasn't very long and there it was again. "Please insert a valid SIM" emergency calls only. I gave her back her SIM as soon as I saw the error, as she was not happy about having the cover off the back of her Note 2. I did not get the error when I put my SIM into her Note 2, but was not able to test it for very long, as I got the error on my S4 with her chip so soon.
Next I am going to peel it apart as thoroughly as I can and look for any connector plug that can be unplugged and snapped back in. There was only one little ribbon with a 24 pin connector from the new tray to the motherboard. I'll pull that off again too, and inspect it with a magnifying glass.
I will report if I am able to figure out how to fix this problem.
My wife thinks it's because I flash it, but I doubt returning to stock is even worth the effort. I've never heard of a ROM being the culprit.

more tape
It occurred to me that the tape making the SIM chip thicker seemed to help the problem and less SIM errors.
I will also mention the replacement tray was identical to the one I thought was bad.
I was about to take apart the S4 again when I decided to try lots of tape! I stacked 4 or 5 layers of transparent scotch tape on the back of the SIM chip and it was very snug to slide into the slot.
It was so snug it barely returned from it's "in click"....
I am pleased to report an "up time" of over 16 hours, and that's the longest "up time" achieved since getting run over by a full sized Suburban on Olympic Boulevard.

How many pieces of tape did you use? I have been having the same problem and one piece helped for a little but but it has since occurred a lot more often.
Any fixes?

I guess I dropped my phone one too many times... started getting the no sim error last week. A reboot fixes it temporarily but the error always comes back (sometimes I'm good for 5 hours sometimes its 5 minutes). Tried the tape method without much luck. Went to the AT&T store to swap out my sim... still no worky. Looks like my only options are replace the phone or fix the hardware. I'd rather not send in for warranty repair/replacement as I don't want to lose the ability to run a custom recovery.
Anyone have any personal experience with replacing the sim/micro sd tray or sending in for third party repair? Found this tutorial on youtube. It looks pretty straight forward and the part is fairly cheap (~ $9) but not sure its worth the risk.

Took the plunge and replaced the sim/micro sd tray myself following the tutorial above. It was pretty painless and only took about 20min. Everything is working and no sim error messages over the past day. :good:

I might keep this in mind, but will wait to see if you really fixed it.
I haven't had a sim error in over a week now, and before that it was over a week as we (just that one time in between).
Sony know what made the problem go away but so far so good.

Well crap... insert sim error just came back (probably jinxed myself with my post). Not sure if it's hardware or software but it's definitely not the sim reader itself. May try to revert to stock just to rule out some variables.
Long story short, don't bother wasting your time, money, or taking the risk of replacing the sim tray.

Me too. Happened twice yesterday.
Is there a possible tasker setting that we can make to restart the sim card if it gets disconnected?

possible fix
So guys I found a solution that worked with my phone. It seems that the ribbon connector that connects the Sim and microsd is really temperamental so just push down on it and reboot and signal should come back. As a permanent fix I took a 1/4" piece of foam rubber weather stripping and stuck it to the top of the ribbon cable (where it attaches to the mother board). This kept permenant tension on the connector when I put the plastic back in place.

Not a bad idea but I've never played with tasker. If that doesn't work maybe we could find a sympathetic dev to write a few lines of code. Might even be a way to make the system query the sim card to reestablish the status and clear the error without rebooting?
I'd definitely be willing to throw in a few bucks for a fix but I don't think there are enough people suffering with this issue to put together a bounty and/or get anyone's attention. I did manage to grab a logcat if we can find someone willing to assist.

Just purchases an S4 on the good ol craigslist with this problem. It was unlisted as an actual problem of course, however I am 100% certain that's why it was for sale.
I too get the No sim card inserted message. I took everything apart, testing out a few variables. I have isolated it to the actual ribbon cable as someone mentioned above as well. It seems if I reconnect the ribbon cable and reboot it, the phone will read it until the error comes back. Which happens more often than not. I can't even get the plastic housing on without the error coming back.
- I have tried the tape method as well. On the sim, on the top of the ribbon connector, on the back of inside phone shell.
- I have determined it was the ribbon cable by applying pressure to both the Sim and ribbon locations, both at the same time which is the first time I got the phone to read the Sim. Then isolated each area with pressure and a reboot. The ribbon cable and pin connector seem to be the issue.
Reading over some of the other posts in this thread it appears people have already tried a new sim/sd card piece with no improved results. That makes me want to lean towards this is not the SD/SIM side of the connector but more so on the motherboard side. If it is the motherboard I then I am pretty much at a loss and it is not deemed worth investing another 150$ into the phone for a new motherboard.
Will continue to see if I can do anything to improve this issue. Currently the phone is unusable as I fear for any movement on the device before it disconnects the sim, and I remain on my S3 while I continue to investigate.

So, did it fix it? I took the plunge and replaced my reader as well...but still randomly getting that error. I do have an i337m and running an M919 rom though. Im wondering if it might just be the rom but i have tried two different M919 roms...

Did I break my sim card slot pins?

Both my Nexus 4 and Nexus 5 are not reading sim cards anymore. I tested the sim in other phones, so the sim works.
At some point I started having problems with the Nexus5 Stock OTA (intermittent sim detection). Then permanently "no sim card".
Now after moving sim cards back & forth accidentally swapping the sim trays between the phones (tight fit), the Nexus 4 isn't seeing SIMs either. I've tried flashing different radios - no improvement.
Could I have broken my Nexus 4 Sim card slot by putting in a Nexus 5 Tray in once?

Based on your description, I'd say the pins may be bent or damaged.
Open the phones, remove the motherboard, take a bright flashlight and magnifying glass and for bent and/or missing pins.

Stuck SIM tray

hello guys, yesterday I was trying to switch my sd card and what I didnt expect, I couldnt remove the tray.
I thought maybe sim or sd was stuck, so after a while, I was able to gently remove it with a knife.
As it turned out, that wasnt a problem and I still cant remove it fully...
ye...why does this have to happen... anyone have some trick maybe? Or experienced the same problem?
Thanks

It's possible that your SIM card (or a storage card) has become disloged, ie; is not laying flat in the tray. I think the best you can do is to gently push the tray back in and lay it flat face up and see if you can shake it a bit to get it to settle into the tray. If that does not work, I would take it somewhere for repairs.

Just cant believe this really...
I managed to break it, so the stuck piece is still in my phone, but now I am at least able to put a sim and sd card into it.
Contacts little bent, but its how it is and the phone works. Will have to ask about warranty service on this, I am really curious, what will they say...
So be aware, even thing like this can happen...

Yes, this SIM tray is very fragile. You are not the first.

Exact same thing happened to me. I believe there is some clip or contact that detects when the Sim tray is inserted or ejected and it gets caught there. They used a flimsy plastic Sim tray and it breaks in the same place.
The SD card and Sim tray still work. Just have to reset the phone when you change it for the phone to detect the changes.

Happened to me exactly like yours...i used a very this bit of plastic, with a bit of blue tack very firmly attached to the plastic and gently, VERY gently pushed it in to the sim/sd card slot and only took 2 attempts but the bit that broke off came out!!
Then went on Ebay and got a brand new sim/sd card tray and voila!
Cost me £4.50 for new sim tray, but working perfect now.

Any ideas on extracting w/o breaking the tray?
I have the exact same issue as the OP (before his tray broke).
Does anyone know any tricks to extract a stuck tray without breaking it?
edit: nm. Broke the tray. Took no force at all.
So the issue here is one of the SIM reader pins is sticking up and is catching the tray. Trying carefully to bend it back where it belongs.
edit #2: Can't bend the pin back w/o disassembling the phone. Going to borrow a heat gun.

Hey there Matt, I got exact same problem, tray got stuck and I rushly pull left over broken tray. I replace the sim tray but now sdcard not working. It is detected and attempt to format the card but fail at 20%. I'm still try to repeatly removing sim tray before I take it to LG.

So you meant when replace that sim tray, you need to hard reset so it will detect the sdcard? Because I have sim tray replaced, sim worked but sdcard wasnt, it keep fail to format at 20%.

You must have damaged some pins. For me all my.pins are intact and the broken piece is still in the phone. I have to do a hard reset for mine if I want to change the Sim or SD card

Same here. Damaged SIM reader pin. Tore the phone down and it's not clear if it's repairable or not.
Regardless, I'm writing off my G6 (just 1 month after I got it). I'll pickup a V20 for now, so I don't have to look at another SIM tray.

I went to LG and they ask for mainboard replacement cost $400, what a joke! Looks like they wouldnt replace only damaged part.

Even if you replaced it. It won't be long before it breaks again in the same spot... If it was a metal Sim tray it would be a lot better. I'm going to avoid LG phones from now on.

Bad design
I have had 3 LG G6s, each one has had this happen. It sticks in the corner by the sd card contacts. After it catches it will not read SIM until i get a new tray. I think there may be some sort of pressure switch. I wish LG would replace it with a G8x...

Even the models w/o dual sim capability have contacts for a second sim. These rub against and can get stuck at the tiny pads on the underside of many mSD cards. This will cause the tray to get stuck in the frame for additional friction. If this happens to me again i will try to pull the tray out with some adhesive tape to be able to apply force in the middle or at the left side, where the sd sits, instead of the opposite side via the hole.
Especially the newer, bigger mSDs seem to have such pads, none of my old ones has one, that's why i didn't test whether you could sadely remove the pad. Probably there's the bare flash die underneath.

I solved the problem...its called the LG V30!
Love it!

Hi, I got the same problem. The tray broke down only for the SD card and SIM slot is intact. But the phone does not anymore recognize SIM card. So do you think that I did not damage the reader and it's only a matter of getting a new SIM holder?

If you ran into the issue with a sticky mSD, the contacts for the second sim msy be bent/broken/shorted. Whereas only a short may prohibit use of the primary sim slot. And the contacts may not even be soldered to the pcb on a single sim phone like p870. Otherwise just the flimsy plastic tray broke. On my Iphone 4s it was made of metal. And the lever to push the thing outwards was centered and not to the right side, which makes even pushing out an empty tray difficult.

I finally got replacement tray and can confirm that SIM reader started working again. So it indeed seems that there is a pressure switch and it did not activate when the SD card compartment was damaged. No I just worry do I dare to remove sim tray ever again.

My current 128GB mSD in the p870 has a sticker on the back like most mSDs at higher (32/64GB and up) capacities, but this time there's no friction with the useless contacts for dual sim.
But anyway, once the tray has been pushed out slightly, you have to try to grab and pull from the opposite side while pushing the pin in, otherwise there's high friction.
