Huh. That's too bad! On the other hand, I've been sim card error free for 24 hours now! Sweet...

Also - while the paper might have made a difference, I also unplugged and re seated the ribbon connector so it's possible I'm experiencing some temporary tightness until it loosens again.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] s8freak:
Huh 24 hours? That's it? I went a month and then it started all over again sometimes 8 or 10 times a day. Doing it as I'm staring at it on the table.

Time will tell, I suppose. But I still think the problem is probably that connector. I wouldn't be shocked if it acted up again at some point - but I'll just pull it apart again. If I get 8 months between re plugs that'll last me til my next phone. If I'd known, I would've gone back to HTC. Terrible design flaw though.

I am up to 24 hours without a problem. This doesn't necessarily mean the problem is fixed...but it's looking really good at this point. 24 hours without a SIM reboot is pretty much unheard of for me. I generally don't go more than a couple hours with regular use without having at least one reboot, sometimes many.

Crossing my fingers that this solution is putting this issue behind me :)

As I've said good luck I went about a month then it came back with a vengeance...phone would sit on the table and the error would pop up.

my phone is canadian Rogers and have unlocked it for my Telus account, I have used this with no problem for at least half a year with same custom rom, suddenly the problem just started happening, I did everything from updating and downgrading modem, clean install rom, and even disabling lte and to only use lower modes, but to no avail, I don't think it's a compatability issue since I've used it with no problem for half a year, I read somewhere that it's caused by an older bootloader which I have,not sure if that would be true.And just recently I tried a different rom,I was hoping that would fix it,but nada.

But with my problem,I never had to reinsert the sim to get back on service,I just reboot it and that connects it back on.Is this the same for everybody?

*the part where disabling LTE may work for some,this is what Ive noticed when my service drops is when LTE is low on signal and tries to switch to lower modes like 3g.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] s8freak:
It has nothing to do at all with the old bootloader. I'm convinced Sammy has produced a big batch of defective devices.

So you traded in the device that was defective and received a different device that is now working. Correct?

Its been happening to me too. I got a new SIM from NSAt&t and it happened again. Then I stuck a piece of paper on top of the SIM so it would push the SIM down more in case it was loose. I went about 3 days and about 2 hours ago it happened again. I think I can deal with until the Nexus 6 gets released.

Just started getting this issue yesterday, and of course my warranty is already up so there's nothing to do but replace it, which I really don't want to do for financial reasons.

Between this and how much of a pain Samsung has been to people trying to get root, I think I'm done with them. When I do upgrade I'll probably look into what phones aren't being so tyrannical.

emulate SIM card via software

does anyone know if there would be a way to emulate the SIM card? i've seen some stuff on copying SIM... is it possible to take that data and use it to create a virtual SIM? seem like if we could just replace the faulty hardware with a software emulation, we would have a solution
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] Austie1337:
It can't be a software problem. Unless its Samsung screwing with our phones so we can upgrade to the s5... Its just a bad design.

My phone also does this.

My phone also does this... I have a M919V variant and I got it the first week it was launched here (videotron in canada). I get random sim removed messages. Well I did a bit of testing and for me it's not random, it's more random-ish. I set a tasker profile to notify when sim is lost so I get a warning as soon as it happens. Most of the time it happens when the phone is jostled a bit harder than average. Like quickly going up some stairs with the phone in a front jeans pocket, or gently tossing it on a bed, but sometimes just dropping the phone in a pocket will trigger it. Well a while ago I took the SD card out to transfer some large files to another device and hadn't had the chance to put it back in for a bit and I noticed that as long as there in NO SD CARD in the phone I can go a long while without having a single problem. I tried 8 days before I needed the SD card back in there. No problems at all. As soon as I put a SD card in the phone (any card... I tried 3 different), I get sim removed within an hour or two of moving around with the phone in a pocket. It's never happened while I was holding/using the phone or while it was just sitting there doing nothing. When this started I was running CM 4.4.2 and I tried updating to CM 4.4.4, then going back to stock 4.2.2 TW and all behave the same. It definitely seems to be hardware related.

Maybe the connector between the card slot and the mainboard is just loose enough that if there are two cards in there drawing power the supply voltage might drop enough that the controller in the chip resets. I'll try to disconnect/reconnect the plug and see if that helps.

I`m now up to 5 days of no issues after trying the solution a few posts back regarding thickening the small black panel on the inside of the case back that presses against the SIM card ribbon connector cable connector.

Those of you encountering this issue...I strongly suggest trying this trick out as it`s not as difficult as it may seem and after trying everything imaginable prior to this...has worked wonders!!

i'm not saying it's a software problem... i want to emulate the hardware *with* software
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] TheDjost:
Well, after almost a week I can say that unplugging and replugging the Sim card reader ribbon connector helped a bit but is NOT a solution. I even put a couple layers of electrical tape on the black part of the cover that presses on the connector and all I got was a few days out of the fix. I did this on Tuesday and was good for the rest of the week. I got the error once Saturday and it's happening every couple of hours Sunday. I even took out the SD card (which helped before) and this still happens.

What's bugging me is why is the phone reading the sim card all the time anyway? I mean could it not just read it once at boot and be done with it? You can't swap it out or remove it without taking out the battery anyway, so once it's read it's in there until the phone is turned off.

Does someone know where is the routine that queries the Sim card is located? Is it a function of the kernel, or is it located in the modem or maybe even the boot loader? If someone knows maybe we can contact a Dev and beg for a patch...

I tried applying firm pressure for 20 seconds to the area where the ribbon is located (without taking it apart).

Ever since I did this, I have not gotten the SIM Card Removed error. It's been almost 3 days now. And it used to happen about 3 times a day.

I doubt it will permanently fix the issue but it's a good indication that the ribbon is the likely cause.

Hi, i have a Really wierd problem, on TW without root so far i have not problem with sim error, but when i changed to custom rom i got the problem.

I have tried several diffrent roms like Google rom and PA and cm, i don't have to take out my som when i get the error i only need to restart the phone and then i works for some time, nerver the same time, sometimes a couple of seconds and sometimes a whole day.

The problem starten when i was on the old bootloader without knox and i tried a couple of diffrent roms, then i tried to update the rom to 4.4.2 and it worked, i rooted and installed PA rom and The problem was back.. Now i unrooted and installed TW without root and it works so far anyway, i installed it 30hours att.

Orded New sim card, didnt solve the problem.

Any suggestions?

I was going to repair it at my retailer but with notting to repair its kind of Hard :p

going with it to the retailer tomorrow, got the sim error on stock rom just now...

It has been couple of days at least without having the error, I have taken it apart and stuck couple pieces of tape on the ribbon connector, or you can stick on the black part of back cover where the ribbon sits. in my case I used 3m film used for cars, basically the same stuff as bodyguardz, zagg screen protectors. It is thicker than regular tape.

I've been having this problem too. Sent my phone in for repair which took two weeks and the problem persisted. Actually, it's much worse since they "fixed" it. Sending it back again on Monday with expedited service and shipping. Samsung could not be more dismissive. I am out of warrantee with AT&T, but for some reason samsung thinks I purchased my phone last February. This has put such a bad taste in my mouth in regards to samsung. Makes me want the g3.

The Story never ends on mine

I got the Error message first after I flashed 4.4.2 KitKat. It could have something to do with that. It was in the End of May, when I got my NFC-Sim Card for my Phone. I went on Vacation to the UK after reinstalling all my stuff. The first time the error occured was by the Time I was back in germany. I have had EE in the UK and T-Mobile in Germany. But after a week or so, the error reoccured many times. Till now they've been a dozen of errors.

Today I first had the error that I didn't had Signal. A friend of mine called a few minutes ago and after we went away= no Signal (Emg calls only)

It gone away after 1 reboot. And minutes later: Same SIM removed error.

I also saw my CPU Temp is going over 100°F, which means, is this HOT or NOT?

Now I had the same error 2 times in the Evening and next is incoming. CPU Temp accurate: 82°F. Idle and locked.

What's wrong with Samsung? The Firmware? Is KOT.49H the default kernel? Is there a default kernel? How can I flash it and where can I load it?

Edit: yet this morning it happend without getting hot

Cheers,

Junpei

I was having issues with this as well. At first a reboot would fix the issue, but it just got worse and worse. Finally this weekend it could not be fixed and I was left with basically an android ipod touch. I called AT&T expecting a fight with them to warranty the phone. They did something where they unregistered my phone completely and then added it back in again and I've not had an issue since.

Just throwing it out there for others to try. I'd guess that some people really have hardware issues, and some might just be having service issues.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] mark324:
If it is 100 f that is like 37 degrees Celsius, that could be around normal temp I believe, I could be wrong. If you are out of warranty, you could try what I did. Mine has not disconnected since.

I applied parcle band on it cuz idk yet what 3m band is.

I hope it works. After i applied it: no errors since a few mins. Will tell you if it worked for me. Thanks for this unusual trick :)
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] rBGH:
Same problem here. It came on yesterday for the first time, (sim card not detected, reboot) and then again today. Only today, I couldn't get it to work. Finally, I took the card out and cleaned it with rubbing alcohol. So far so good.

I'll be looking forward to a fix since my phone was purchased second hand and not under warranty.

parcle band instead of 3m band

To the story - I applied it and til this morning around 11am it worked fine til it again said: SIM Card not Inserted Error.

Did the Band on it.

A Question to mark324: how much do you use? Do you used so much that the card is hardly pressed in?
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] cegna09:
just kidding. Got almost 2 days and now my phone is all screwy again. No rebooting will help. Going to try for a warranty replacement tonight, and if that's turned down i'll just buy a new sim try and install.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] brooklynite:
I wanted to add my 2 cents here.

Bought my Galaxy S4, for AT&T, July of 2013, directly from AT&T, OUT OF CONTRACT FULL PRICE (maybe that is the culprit? Samsung sends the faulty units to out of contract people since AT&T is so helpful is swapping out bad phones right away?).

Phone had intermittent "no sim found, restart" popping up. It go so bad in December I sent it in for repair, Samsung (apparently) replaced the SIM tray and fully reset my phone. Months of customizing my phone to my settings was lost. The new SIM tray caused my 32GB Microsd to bust in two weeks and i lost a bunch of photos.

Phone developed the same issue really bad in April of 2014, sent it in, they just reset the phone and sent it back. Again all apps and setting gone. Problem is exactly the same issue like everyone else described. Comes and goes, sometimes weeks.

The worst thing is that it happens when I am not aware, so I pull our my phone from my pocket and notice I have not been connected to the phone network for hours maybe? So no one couldve called me. What THE **** SAMSUNG? What if there is an emergency? Cant the phone just reboot itself when it cant give me a second choice, NOT EVEN TO TAKE A DARN PICTURE? Why does the phone have to LOCK UP 100% BECAUSE of that error? Many times I pull out my phone to take a snapshot of my baby laughing and the RESTART SIM doesnt allow me to take a picture.

Problem went away for months then came back and hit me for 5x to 10x in a day so I called Samsung and setup appointment, but was not able to send the phone. I didnt want the hassle of shipping and not being with a phone for a week, plus loosing all my settings and apps. It takes me months at a time to get it back to where it was and it usually doesnt go back exactly. I cant find my favorite apps.

Samsung's US Customer Service is TERRIBLE. With a big T.

Its not a SIM TRAY issue. Its not a physical issue at all as it happens when my phone is simply sitting on the desk.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] mark324:
Where did u put the tape on. You actually have to take the back of the phone, take the screws out and put the tape on top of the Sim ribbon connector, the tape I use is thicker that regular tape, probably twice as thick, I put two of them, so maybe try electrical tape 3 or for pieces. YouTube s4 Sim port replacement, you'll see what where the ribbon connector is.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] Junpei_Shibayama:
Ah that ribbon connector

I placed it outside on the back cover. But I'm way too nervous to take the phone in pieces to do so.

But if this helps, I may do it next time.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] mark324:
Yeah it may not work as well. The back battery cover won't make the ribbon sit as tight to the motherboard . and it is actually easy to fry the back open. YouTube it, it is easy. The Sim tray replacement videos in YouTube helped me. All I needed was screwdriver and my thumbnail

Did what mark324 did. Placed paper pieces because I didn't had 3m electrical tape. Works good.

But the next problem I reencounter is a random reboot. May I can fix this and it works. SIM works til now. Did it today at work. :good:
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] s8freak:
6 hours? I've had a month without the error then right back to many times a day. Happened with the phone actually sitting on the table doing nothing.

Personally I don't think there is a permanent fix. I think Samsung knows all about it. It's a design flaw they don't want to own.

I've moved on to the S5 and given my son the S4 and he's had it two weeks now without the error.

Strange indeed.

Problem withy Sim card

I also have the AT and T galaxy s4. Keep on getting insert sim card message. Tried everything... Tape, Factory reset, clear cache, replaced sim card reader and sim card. Nothing works. Sending to samsung repair waste of time and a loss of two weeks. Wanted to charge me $100 for screen replacement that had nothing to do with problem. Put sim card into iphone no problem.. I have read that it could have something to do with android upgrade or AT and T service. Spent hours setting up phone again after many resets. Phone is only 7 months old. So can not get an upgrade. Phone also checked by technician.. I may get 30 minutes to a couple of hours. It is a nightmare and I have nothing else left to try... This is a very big problem and samsung should have a recall...

Weird.. I haven't done anything to my phone and I suddenly stopped getting the error for over a week now. I used to get it at least a few times a day. Did the ribbon "stick" itself back to the motherboard on its own or something? Very odd. Hopefully it permanently fixed itself lol

I got the error several time. So fixing it may be a sw error. I've a friend on 4.4.2 but on a different Baseband. Does someone know, if baseband xxugng8 has something to do with the problem? Also, my phone reached 150°F today for a few secs. Don't know what I can do. Rooted and stuff. My Insurance offers 1(!) 1-1 Phone replacement and I'm afraid of the fact I get a poor factory refurbished one w/ the same problem.

I was just wondering if anyone had this error, but the phone continued to function properly. I get the error repeatedly throughout the day on my Sprint S4. Restarting clears the error message, but the phone continues to function properly even without rebooting. Happened last night right before my girlfriend called me, but I could still answer the call, talked to her for twenty minutes, and then used mobile data to Google something before I reboot to clear the error.

I noticed that the error message is part of the SystemUI, so next time it comes up, I'm going to try force closing the apk and restarting it to see if it clears the error and keeps it cleared.

I don't see how calls and mobile data would work without a SIM inserted, seems so illogical...
