Well I think I have tried just about everything, but I thought I'd check first to see if anyone else has ran into this and fixed it.
Yesterday my S5 just decided it didn't want to connect to the VZW network anymore. I was running Alliance ROM at the time, but I Odin'ed back to complete stock and it is still not connecting. Wifi, bluetooth, etc. all works fine though.
I took my SIM card out and put it in my wife's S4 and it connects fine so it's not my SIM. I tried reseating my SIM about 20 times and still no love.
Any thoughts?
I'm having a similar issue. Had my s5 for a week now and it keeps dropping data whenever it feels like. Then comes back on randomly I'm going to swap it out for another one. If the new one still bad I'm going back to my trusty s4 (need to replace digitizer)

So just recently my phone has been acting goofy. At random intervals my phone will pop up with no Sim card inserted. A quick roboot and I'm back up and running like nothing happened. Sometimes it does it every 10 mins and other times 6-7 hours before it happens...I live out in the boondocks and the closes att store is about an hour away. Do you think its my sim card or the Sim card holder.
I know the s4 is a repair friendly phone but I haven't the slightest idea on how to fix it. I'm rooted and running alpha ROM. I reverted to stock recently to see if that would help and no dice. One pic is Sim card missing the next is right after a reboot. It also happens when the phone is just sitting still. On the charger and off so I know its not bumping into anything.

Have you removed the back panel and checked if it's mounted properly into the slot?

Don't mean to double post but I just noticed.....I haven't had any issues all day with it till I got to work on there WiFi...I work in a metal machine shop in a building made of tin. Would that cause problems. From about 9am to 9pm my Sim card was fine...I start work at 10pm and it just popped up with Sim card not inserted

I think I'm having the same issue. It forces me to reboot and then it works for a while. Ive gotten a new sim and switched ROMs and still get it. I think it happens when the phone switches towers or loses signal, its usually fine when I stay put. No idea how to fix this, I've googled like crazy
Edit- now I'm getting it during the day constantly even while not moving. This issue is driving me insane
Yea. Its deff a major pain. I'm thinking its maybe the Sim card holder now that I'm not the only one with the issue. But I haven't the slightest idea on how to replace it

My sim card holder has finally stopped recognizing my sim card altogether now. In the notification bar it says no sim and shows a sim card now on every boot

Mine is still random....no matter what I do I can't get it to happen on demand to figure out the root cause.

Mine was random then it completely stopped for whatever reason...I took it to metro and they couldn't figure it out after they put a different sim in so I took it to best buy to the samsung peps and they reflashed mf3 to my phone to c if that would fix it but all it did was remove root and my launcher and home screen and added all the crap ware back to the phone but luckily my lock screen let me use my apps to re root and re safestrap and rom this thing...im pretty sure its the sim card reader/holder thats messed up...the guy at samsung said to return the phone to samsung with the manufacturer warranty cause its something to do with the phone not what I did to it

same problem on stock rom... sim card unmounts completely randomly
Ok so my problem got solved...i went to a authorized metro dealer and asked if they had a tester sim card just to check for myself if it was the card or card holder, and it was the card that was bad cause when she put the new one in all my data came right back like it never had a problem witch is crazy cause the corp. store did the same thing they said, but i never accually saw them swap it out but whatever, my phone is fully operational now and im glad that i didnt try to update to 4.3 yet to c if that woulda fixed the issue (dodged a bullet on that one) so yea, maybe yall might could try this fix if u havent yet and i hope it works for yall...it only costed $15 for the new sim card
Edit: ok so it only helped a little cause it started unrecognizing my sim at random again...but hey at least is finding it after I reboot again instead of not finding it at all

Welp, another thread I have to bump. Any updates on a fix? Mine has been doing the exact same thing and usually only when I am connected to a wifi signal.
This only started recently and only after I started using wifi to chat through Watsapp.

I'm going to need to bump as well. I'm having the same issue and Iccan't find a fix. Tried 3 different att Sim card replacements and I even changed my tray too. To no avail not sure if its hardware or software and still happened after an Odin. I'm thinking I messed up an antenna or something.
Weird, I haven't had an error in 5 days now. And I didn't do anything differently
Hello
This seems to be a fairly common problem. I was wondering if anyone has a solution. My phone keeps dropping signal randomly and makes me restart to get it back. Usually it comes back in 1-2 restarts without anything changes to hardware (ie battery pull, sim pull, etc). Also, i have replaced both the sim card and the sim slot. And i have a piece of tape on my sim car to make it a little thicker.
I just upgraded my modem to mk2 and this seemed to help slow the drops but not stop them completely (have had 1 in 24 hrs). I already odined back to stock to no avail. Right now im on kitkat (gummy rom) with ktoonsez kernel and im about to change to kangakat.
Any help would be appreciated.

I had this happen with my SkyRocket, went to the AT&T Store and they replaced the SIM. Never happened again.

I had them replace my sim 2 times already. Watched them punch the card out in front of me.
I'm am so frustrated. Lol, I called verizon today and sat on the line waiting for what seemed like forever and after talking to someone I finally got transferred to "technical support." Well, lucky for me my home phone decided to die (about an hour after I pulled it off the charger to call them) and am now waiting to speak to another representative where I can once again be transferred to verizon's technical support. The reason I called them is because I get no mobile data. When I first got the phone it worked some of the time, but now I get nothing. Calls and texts come through fine, but after toggling mobile data, airplane mode, pulling the sim, restarting the phone, and numerous other things like clearing cache I still get nothing. The phone is stock and not rooted. The 4g lte logo shows at the top of the phone and everything, it even shows a little down arrow as if it's trying to get data, but nothing is coming through. Is there a good chance it's a bad sim or should I just go ahead and factory restore the device? I'll try putting the sim in my galaxy s3 and see if it works, but this sure has been a frustrating night.
Edit:I'm thinking it's the sim as mobile data does not work on my s3 either. I still have the sim from my galaxy s3, anyway I can set that up to work with my galaxy s5, or will some functionality be missing?
Just go into a vzw store and they will give you a new Sim card

Hey, it might be a problem with the sim / a problem on Verizon's end. But did you Odin a stock rom recently?

yeah, looks like a problem on verizon's in. I got a new sim card and it still quits working at random times.
It's strange to observe the behavior when I used AOSP N ROMs, my Tmobile SIM got killed (got the No SIM card inserted error, AP toggle doesn't help) after a while using the phone. I tracked it down what I think the cause but not certain is enabling Wifi calling on my 6P which from what I learned is not officially blessed by TMO. My theory got crushed because after booting up with Stock N, everything is working. I then flashed back to AOSP again and again but kept getting No SIM error.
I'm currently using stock N and everything is working as expected, however, I have one occasion where LTE was killed but coming in/out of AP mode gets it working. I disabled AP mode now to see if the same behavior can be reproduced.
Anyone get some thoughts?
Not trying to hi jack your thread but wanted to say I'm having same issue.
I'm on Metro PCS/T-Mobile and while I was on stock N just root everything was fine then when PN7 was released I flashed it and about 3 days ago out of the blue I noticed in the notifications that it said No Sim Inserted so I toggled AP mode still nothing so I did a full reboot and then it worked again.. This has been going on at least 3 to 4 times a day.
And only a full reboot seems to fix it.
Its getting to the point that I'm about to just flash back to stock with root..
But I haven't found no answers either from Google search

Just picked up one of these phones. Really like it so far! One issue I've noticed though, after a few days of ownership, it's randomly dropping/not detecting the sim card? It's happened at least twice where I've left it to charge over night and woke up to the no sim icon, and yesterday at some point while I was watching YouTube videos in full screen (in my hands, off charger, no notice of the drop either whenever it actually occurred). Quickly popping the sim tray out and in resolves the issue. At first I thought it was because I was using a manually cut sim card, so I've since replaced the sim but the problem persists.
Anyone else have this issue? Should I have the device exchanged?
Thanks
First the phone froze and after restart dropped sim
I just had the same issue occur just now. The phone had frozen for over an hour before I did a forced reset and now when it started back it shows no SIMCARD and no connectivity. I am like you, I really like this phone but hopefully this isn't a permanent issue.
Watched it happen just now. Goes from bars to no sim icon without error or notice. Resetting the network settings, resetting the phone, and powering it off/on won't fix it. Literally have to pop the sim in and out and its recognized right away.
I lost sim recognition after I flashed to LOS 11/30 and no matter what I tried, phone would not recognize the sim. Once I flashed back to stock, it came back. Hopefully this was due to the rom and the problem won't come back.
I am not sure if I lose the SIM, but I will say that when I am driving around with Android Auto, I constantly see the cell signal go from LTE to no signal every couple minutes...

Had same issues when I flashed back to stock I actually have better signal than when I got it out of the box.... Almost as if the software wasn't installed correctly or something
Same here I'm on the stock room. I'm wondering if it is an app I downloaded. Any idea how to wipe cashe not the apps but system.
This is happening at least twice a day now. It seems to be software related. Power off and on without taking out sim fixes it.
