Nine times out of ten, if the sim card is bad, and/or the phone is having trouble reading it, the phone will say please insert sim card, or something like that. Try re-flashing the radio.

i didn't use your method.
ok it's really weird....Just as quickly and mysteriously this problem came, it went away the same way.
problem popped up several hours ago, and now out of nowhere my sim is all fine again, phone suddenly read sims and i get signal.. and i didn't even do a thing....i'm so confused now. would have been better if fixed it since i would know what the problem is but now it fixed itself somehow and i still don't know what was the problem.

G1 Connection Issues

Recently I have been having this problem where my phone will have connection to the network for about 3 hours max then it will loose service completly. Then if i try and switch to 2g only it doesnt do anything but stay without connection then i will restart the phone and it will give me the no SIM card notification and even if i try and select the network manually it will say SIM card not registered on network anyone having these same issues.
I am running JF1.5ADP with lucids apps to sd

After that, nope. Go.
I had this happen to me once. I rebooted a few times, and Reseated the SIM card and that seemed to fix it( Although, i don't think that is what actually remedied the problem). That happened about a week ago, and i haven't had any problems since.
Running JF1.5ADP Also.
Oh, And c_low: Don't come into an Android Forum and start talking about getting an *phone. I don't think it'll get you any non flame replies.

Sim card umounts randomly

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

Im having this same issue but I live in the city and my signal is pretty descent most of the time except when im getting lte service I only get 2bars and no more. I have taken both my batt and sim out for a few mins b4 i put them back in to c if that helps and it doesnt. My phone still wont reconize my sim just like the op at crazy intervals. Plz any help would b appreciated. Do I need to get a new sim or is it my phone

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.
sent from my guy Fawkes riding a pink unicorn S4
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

[Q] Mobile data not working

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?

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.

Signal drops randomly (and frequently). Verizon.

I have a problem with my 6p where the signal just drops to nothing (Looking for service) and 3 or 4 seconds later it reconnects to a good LTE connection. The problem is not my connection as I live in a good area. I was rooted with xposed but for ****s and giggles I went back to complete stock and it is still happening.
I have reset the APN settings to no avail. Is this a thing that is known to this phone? Should I get a replacement? It started just recently it seems as I have had this phone since launch.
What sucks is, is that this phone is absolutely perfect (or was) and I dont want to get sent a phone with screen issues.
EDIT: I ended up getting an RMA and everything is hunky-dory.

What radio version are you on? You can flash a different version in fastboot and see if it helps.

Im on the newest one. Do I just extract it out of the 6.0 image file and just flash it over the top of the existing one?
I forgot to also mention that I tried getting a new SIM card from Verizon but that did not fix it either.

Did you ever find a remedy for this problem? I'm having the same issues on t-mobile so its definitely not network or a similar related issue. Did flashing the radio from the 6.0.0 rom fix the issue? I already tried several different 6.0.1 radios and a radio from 7.0 but to no avail. I'm about to try it and if it doesn't work I'm getting rid of this phone.
I'm going to assume you mean you'll be on LTE for the longest time then all of a sudden signal completely drops then comes back on, but without the LTE signal showing near the bars, so you'll have to airplane mode, then switch mobile data on and off, then do a restart. If this is the case. That has been a documented CM13 issue for the longest time. I had the same issue with the HTC M8...

I am on LTE but as the OP said the signal randomly drops completely for 4-5 seconds them comes back LTE and all. I don't have to reboot or anything. This doesn't have to do with cm13 though, I've tried flashing back to full stock and I still have the problem there too.

Damn man...I have no idea - possibly radio like the guy above my post mentioned. Wish I were of better assistance.

I've managed to get a logcat at almost the exact time the signal drop happens, I had to put it in a Zip since the Txt document was too big for the thread. The drop happened in the last couple minutes. I'm hoping someone here with more experience than me can help me solve this issue. Thanks in advance.

Same problem here. On Verizon
Anyone find a fix? I'm on the latest Android N Beta on Tmobile and still have the issue.

Did you know your sim card could go bad?

Just posting hoping I can help someone out.
I have a Nexus 6P on Verizon. Starting last night I had a flood of text messages come in at 3AM, when I woke up and investigated, I found these text messages were sent earlier in the evening and they were coming in late. I was getting text messages hours later. A little later my LTE stopped working completely, I could only connect to 3G no matter what I did (restart, airplane mode, reset network connections). I was about to do a complete restore but decided to try my wife's sim card (AT&T) and what do you know, LTE connected just fine.
I go to the Verizon store and get a new sim, LTE connected right up. Very odd, I never knew sim cards could work partially I though they either work or don't work at all.
This happened to me on my old m8 way back. It can happen with sim cards from time to time.

Oddly enough, my phone before the N6P was the M8, in fact it's the same SIM card I was using from my M8.
