[Q] no sim detected - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Hi guys im having problem with s4 i337 i do factory reset and now no detected sim when i try to make a call it say network mobile not available, i check the imei and already have it i cant navegate with wifi, only no detected sim card, i check service mode and its empty, the efs folder with es explorer file and its empty too, the cellphone have stock rom without root, i have any possibilities to fix that?? sorry for my english, Im from El Salvador.
Thanks.
Edit: i root my device and use root browser to see efs folder contain and thats it (images)
is missed some archives?

nobody have any idea????
the efs folder is corrupt??
please any suggestion i really appreciated it

EFS only affects IMEI and things like that, it has nothing to do with your SIM card
check the card itself first, it might be damaged, if you have some spare phone test it
if the card is fine check the SIM tray
if it's also fine then it's either an internal circuitry problem or software-related
EDIT: some custom kernels have SIM disconnection problems, but I assume you are on the stock one
try changing kernel, that might work
and by the way, if the EFS was corrupt, you would be left without IMEI, maybe your phone ain't booting at all, plus you would have never been able to check its contents with a file manager

also I've taken apart my S4 and replaced the SIM/SD tray to no avail
tried tape on the sim chip to make it thicker
no luck
What did seem to work (still testing, so far so good) was peeling the phone apart again, all nine screws, and broken finger nails, and I unplugged the connector from the new SIM/SD tray and plugged it back in. This time I got a very positive click. Make sure and get your gigantic finger square over that tiny plug and after it's lined up do your best to press it straight down.
Seriously. I got a good click this last go around and it seems to be doing the trick. My S4 was run over in the street and it is only still alive because of otterbox.

Remove the back cover, battery, SD card, and SIM chip.
Take out all nine screws with a tiny Philips head.
If you don't want to break finger nails use a guitar pick and peel the glass edge away from the chrome side bar all the way around.
Pop the plug off the tiny ribbon cable from your SIM/SD tray from it's place on the motherboard with your fingernail.
Plug it back in as square and straight down as possible.
Reassemble. Make sure all nine screws are all the way down as if some aren't screwed in all the way the back cover won't fit tight.

Yes man sometimes only has 1 bar but only during about 30 minutes

[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.

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?

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...

Nook won't turn on....

"Your NOOK has turned off completely."
Yikes. So today I discovered there was something wrong with my NookManager SD card when my computer would not read it. I reformatted and wrote a fresh image and then wanted to make a backup (since the previous one was lost). I shut off my Nook without any problem.
But I nearly could not get it to come back on! And I never have succeeded in getting it back on (only twice so far) with the SD card in, so I haven't been able to do a back up {smoke comes out of ears!}. It is fully charged.
I've always thought the switch on the back was a little wonky but this is so sudden and, of course, at the worst possible juncture. Is there something I could have done in the system which would make the Nook difficult to turn on? Or is my number simply up and the power switch is all-but failing?
ADD: I just popped the SD card out for a sec and tried again and it came on almost on the first try. It reads the normal SD card just fine (where books and such are stored). Can there really be something with the NM SD card that is keeping the device from turning on? I just tried again with the storage SD card in place and the Nook started up once again without problem... And now it won't....has to be the switch?
EDIT: It's got to be the $#%& switch. I finally got it to come on with the NM SD card inserted and did a backup--which I copied over to my laptop. I tried invoking a reboot via wireless ADB with the NM SD card inserted to see if a warm boot was sufficient to the task. It worked! I may never turn off my Nook again.

I had a similar problem when my Nook was almost brand new, I came to the conclusion that it was a problem with the way the microSD card was inserted, it wasn't right somehow. I had problems when I first had the NST with getting it to work with a card inserted. SO, there may in fact be an issue with your card.
That said, now that I have had my Nook for a while, and made much use of the on/off button, I do indeed have issues with it. I practically have to grip it with visegrips to get it to do anything. I plan to remove the plastic button and investigate further soon, I will try to let you know what, if anything, I find out when I do.
I do already know that it is a more or less typical metal dome.button switch I suspect it has become deformed with use.
More when I have details/proof.

Well... Color me embarrassed...
It is, in fact, a sealed solder-mounted part, probably containing the above type dome/button, but it is a discrete part. At least on my NST.
I did, however, find that the screw just above it, that holds the case back in place (it slides off once the screw (AND the SD card!) is removed) was slightly loose, as were all the screws inside that held the circuit board to the front case. Not significantly loose, but a good 1/3rd to half turn for the inside screws, and maybe a bit more for the one above the switch.
Also, there was a fair bit of ... dirt, dust, white stuff, I dunno what it was, but we'll call it dirt for the moment, between the external switch cover/button and the case itself.
So, I cleaned that all out (a good blast of canned air), removed the back case and tightened all the screws, replaced the case back and the screw that holds it in place, and popped the external 'button' for the switch back in place.
End result, the switch now seems to work much more easily and reliably, without having to use a 'death grip' on the button at all.
This is the second time I have been inside my NST, and I found the tear-down instructions online, somewhere. It has been a LONG time, so I don't remember where, but I'm sure you can Google for it.
MildBill
P.S. I should also say thanks to you, for being the prompt that got me to fix my own issue with the switch, it was driving me bonkers at times, but in itself wasn't enough to make me break out the tiny screwdrivers! SO, here's to you, fellow Nook user, and I hope my story helps you!

Yipes... I've done just about everything else to my poor Nook but I'm really timid about opening it up (although I generally take wayward electronics apart at the drop of a hat). I dislike cases that were not meant to ever be opened again by human beings. Too much chance of cosmetic damage. But...... I'll soldier along with it using ADB to initiate reboot until I encounter a situation where that does not work (or my Nook freezes and I can't get it to reboot with the power button....).
But thanks for letting me know and indicating there is a way to get inside. I think I must have come across that also at some point and probably shuddered at the thought!

Actually, other than popping out the power button on the back, which is pretty easy, the case opens nicely.One screw, which is under the power button (and a paper tamper seal ), and with no card in the card reader slot, you simply slide the case apart and the back comes loose from the front easily. And, slides back together just as nicely.
Let me see if I can find the tutorial on how to take it apart. I'll edit with the link if I do...
MildBill
EDIT: Here's this one, focus isn't always great, but at least the action is always onscreen. I used a very small screwdriver instead if the Simcard, you could also use what's called a splooge, a plastic thingy for prying apart plastic cases... You will also need a T5 torx driver.
http://www.youtube.com/watch?v=q7U7TfBIXH0
I use the small blade on my Swiss Army knife.
If you push the power button very gently (not actuating) you will cause a gap in the lower edge.
Insert the blade a bit under the edge and pry both upward and outward.
I do this a lot.
I do this a lot.
Lol Probably more than anyone else in the civilized world!

Micro SD Problem

Hello, I have a problem with my SD Card, every time I reboot my phone a notification pops up saying my card is damaged and it needs format, then it works until I turn off the phone and turn it on later and format it again. My card was on my S4 without any problems, now with the format, Windows does not recognize the card anymore. Can you help me?
Same problem here... I format it and it still gives me the error...
Any solution?
/CK
E D I T :
The card works as usb otg on my S6 Edge+ and my pc reads it with no problems... Hmm... No idea what's going on here
Its officially a harware issue
I have had the same issue non-stop for a while. I did everything mentioned here without any exception. Its not only the notification. Its also when you are listening music and checking photos from your external SD card that the device suddenly stop responding. I have a friend who work for Samsung Canada and he is in a "high level position". They have been aware of the issue since March 11. All their first shipments (their first batch) has this issue. And they quickly worked on it for the second build. However, we don't exactly know when this second build will be on the shelves (they may already be or not). Sometimes, it takes months. Because they had a lot made before the launch. And they will pass all of those before going to the second batch with the fix. Its an hardware issue officially. Sad but we got a lemon. We are now stuck with it. I would certainly be more than happy to flag this on Twitter, Facebook, everywhere possible. Where is the facebook page to complain.
Please note that this can go away for a few days but will come back. No matter what you do (hard reset = I did 8 times), 2 micro SD, one Sandish and one Samsung = same problem. Unfortunately, it is a hardware issue. If I were you, I would protect my phone with a case and screen protector (to ensure to keep full warranty of the device) and wait a few months to get a phone from a new batch. I have a friend who works at Samsung Canada and he anonymously told me that this is a known issue by Samsung who will not admit it and they will still sale the batch that was previously build with this issue. Once they get new batch, this will be fixed. Also, my assumption is that the issue will get worse overtime (sun, cold, bending, pockets, etc). Good luck.
Hey Christian99,
Wondering how to determine if phone is from the first batch.
Can you install Phone Info Samsung and it will tell you the manufacture date... let us know your date.
Or better, maybe your friend can tell us.
Thanks!
Try to put a piece of thin tape on the side of the card without the contacts to make it very slightly thicker and a snugger fit.
See if that helps...

I do not have the issue but have heard that thin tape stuck on the opposite side to the contacts to make the card slightly thicker helps to keep the contacts in place and prevents issues. I would use the thinnest you can find to start with. Just be careful not to get it jammed in there with very thick tape....
I have not been having this issue. Yes when i first boot the phone up / Restart i will get a notification about the SD Card to transfers files.
But this is a normal notification, nothing out of the normal. The device is telling me i have a SD card, Swipe the notification and it does not re-appear until the phone is rebooted.
If you attach a USB pen to your PC and reboot it, Does windows say you have a USB pen connected.
(Just stating the obvious)
For the people who have it re-appearing throughout the day, this is behaviour of a bad connector or corrupted sd card.
Same issue for me.

I have 2016/02.18 Vietnam and no issues at all.
I would post details of the cards rather than the phone. Also try adding tape to the card to make it a snugger fit and pressed up more against the contacts but be careful not to jam it in there so use thin tape.
First card SanDisk ultra 128 XC I Class 10, second Samsung 64 Evo + and the last SanDisk 64 XC I... When one card not recognise, all of them not recognise. Flash with odin to resolve or recovery with Twrp at one time where all was good. Simple factory reset don't resolve the problem. Sorry for my bad English.

Chiming in to report having the same problem. I cannot check the build date since I returned the phone already. I used Sandisk Ultra 128GB SDXC
SD important info
Can all of you download the app "phone info samsung". It will tell you the date it was manufactured and also the place. Mine is 2016/01/11 from Vietnam. Can you post on here? Those who dont have the issue, please also do so and post on here. It may be that the first batch was badly made and/or the place it was made from. Please post. I am currently discussing this with Samsung Canada directly.

So the same side as the connector (on the opposite of them of course) not on the top of the SD (so it cannot get stuck in the tray right?
FYI - I do not have the problem - SD Card works fine (Samsung 128 GB Pro) Created on 3/1/2016 in Vietnam

I would have thought on the other side to the pins on the card. The idea is to push the pins cost to the connector inside the phone.

If you move data to SD, example for titanium or others. After reboot you lose access to SD. Not every time but sometimes and random. So Re flash more ten times and the problem continues.

Make sense. I would just be afraid that the tape unstick itself and when removing the tray, it would get stuck in. But I do not intend to remove it. So I will try this.

Then it could just be the tray the issue. If it's that, Samsung will send a new one to me as I am currently in negotiations mode with them. It is still a defect problem of some kind. An inexpensive one for Samsung if (and only if) it is the tray and not somewhere where the pins connect to the SD.
No problem here with Sandisk ultra 64gb and SM-G935FD

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.
