My sim reader appears to be dead. The other day I go to use my phone and it says no signal, restart it and im good, browsing the web when all the sudden i get a message about no sim, insert sim and restart phone. So i restart and it was good for a couple days. Today my phone will not read a sim card. Tried my girlfriends captivate sim and no dice and my sim worked just fine in her phone. I odin back to stock to see if it would help but no dice. Seems like it must be hardware to me, has anybody had a similar problem.

Sounds like a bad solder joint or something hardware, unfortunately.
Hardware defects are covered by the warranty, should be able to get it replaced with relatively little hassle.... i say relatively, cause any time you're dealing with a warranty department There is inherently some hassle.
I use my HTC Legend as a backup phone (well planned to anyway). It is s-off, rooted and running cm7 (same thing happened on cm9 and 10). The phone initially was working fine - however one time the phone's battery was running low so decided to shove on airplane mode. I simply could not turn this off - when attempting to disable, nothing would happen and would just stay on. It took me numerous different wipes of the phones data/everything i could think of plus flashing multiple roms until i could get out of airplane mode. It again worked for a while - however, since this isnt my main phone there isnt always a sim card in it. I tried using the phone this weekend - when inserting the sim and turning the phone on - boof! airplane mode activated and unable to disable.
Has anyone else experienced such issues ?
I'm using a micro-sim card with a simcard adaptor in the phone. Could this somehow be triggering this ?

That is such a strange problem. When I was in the States, I overheard some people complain that their SGSIIIs (and one guy's SGSII) would randomly turn on Airplane Mode whenever they dropped signal or service. The SGSII guy could resolve the issue by doing a battery pull. All of them were on Verizon.
I can't really think of any other triggers to this problem. Do you have any apps that are allowed to turn Airplane Mode on automatically? Tasker? Some new CM7 Power Saving feature?
I run a MicroSIM card in my Legend with an adapter as well, this is my second MicroSIM with this phone. I don't believe that would be an issue.
Unless for some reason the SIM was not an actual MicroSIM but rather a regular SIM cut quite poorly, or in any circumstance disallowed the SIM to behave like it usually should, therefore cutting the signal and activating the Airplane Mode glitch like the others above have had.

Thanks heaps for your fast response - i wish it was as simple as a battery pull! haha - and nope only have about 3 apps on the phone (ebay, facebook and tapatalk) hmm ill try if i can grab a normal sim card to test - as my micro-sim was cut down from a normal sim - however ive had no other issues on other phones.
If not ill try flash a stock rom if i can find one.Thanks.
Yep! seems it's my sim card - just tried using a standard sim and all worked fine! strange considering initially it was working fine.

Ouch. Maybe you can ask your carrier to issue a new standard sim so you can try cutting it again without incident this time.
Or, if possible, try to buy a brand new microsim straight from the carrier. That would be the best and economical plan of action.

so let me preface with I'm rooted, s-off, global, not retarded, been flashing roms since 2008, etc. etc. etc.
I did a nandroid, wiped, put a T-Mobile Pay by the Day SIM card, and booted into the GSM MIUI installation. My goal was to test to see if I had the 1900 HSPA+ network in my area, which I unfortunately don't. Seeing as how I still had this SIM paid for for another day, I figured I'd play around with GSM and test the EDGE speeds and whatnot. About 5 minutes into my GSM molestation, the touch screen started becoming unresponsive at times, and began making phantom touches. The best parallel I can make is the "crazy mouse" from the days of yore that always ended with a computer reboot and blowing out the mouse.
Seeing as how I had replaced my digitizer the previous week, I was very terrified that I got a bunk digitizer.
I went to recovery, flashed a CM9 GSM ROM, and had the same problem. Feeling defeated, I put my VZW SIM card and restored my nandroid to see if I could retrieve some data off the phone before doing a warranty or getting a new phone completely, and the screen was completely responsive again!
Has anyone experienced this issue before?
There is no possible way that it is SIM related. Did you pop the GSM SIM card back in and the problem came back?
Any chance you were plugged in charging at the time

I just tried the one sim with 2 different ROMs (system wipe both times) then went back to the VZW SIM.
come to think of it, I was charging, but I always use my phone while charging
I had this HTC Amaze for over a year on T-mobile and worked great.
I have dropped it few times before and never any issue.
Last week, it just slid down from my knee to carpet and then it lost network.
All signal bars are grayed out and there is an x next to it.
Sim card or no sim card, it's still x on the bar.
No networks found when checked.
Also tried airplane mode on/off.
Tried changing GSM and GSM/CDMA auto etc...
Reset to factory.
Still same thing. Now I have a small tablet instead of a phone.
I used SIM in different phone and works fine.
I opened the back but everything looks good. Nothing loose or broken.
Is it done now or any hope left?
Thanks
i think you should probably have it repaired by those guys at the service center or anyone you know who does this kind of work
otherwise.....i don't think you can do anything about it.....and better try to keep your tablet safe ,or you'll even damage that!!!!
Ok u flashed a rom and have No SIM inserted or no service or that kind of error.I found this fix trying out things for myself.Take out your SIM card ,turn on airplane mode,reinsert it and turn off your phone(not reboot but power off).Wait for 1 minute and power it back on.Tada!Should be fixed!:fingers-crossed:
Thank you!
Thank you so much! I was worried I was going to have to try one of the more complicated fixes I've seen here. I was puzzled because after performing Joseph230's procedure to root and "convert" an S4 from AT&T to T-Mobile (http://forum.xda-developers.com/galaxy-s4-att/general/convert-i337-to-m919-wifi-caling-t2896719) everything seemed fine and I reinstalled all my apps. Then, I get the "No SIM inserted" error out of nowhere!
After much researching I was losing hope of finding a fix guaranteed to work. Then I found your post and it worked like a charm! :highfive:
robermaldo
Thank You
Im so glad that this worked because I was losing hope that my imei or something was broken and I git scared then I found this and it actually worked I thought it was because 5.1.1 or something anyways thanks for the help I actually loged in my XDA account just to post that cause I just always use the browser
A coworker brought me his G2 that I have taken apart to fix many times before because it was having problems charging and turning on (black screen; rhythmic buzz from the vibration motor). I worked around that to get it booted temporarily but then the SIM connection seemed to suddenly fail. I replaced the motherboard entirely because some charge/power issues persisted and everything works perfectly EXCEPT that the replacement also doesn't see the SIM. Both are running stock LG Verizon Lollipop (assumed installed by OTA). No one was playing around with alternate ROMs or anything. None of the fixes in this thread help. The SIM slot is on the board so I hesitate to assume that the charge, mic, headphone flex PCB has something to do with it, but it is the only major common component (even replaced the screen again along with the battery, speaker, etc while leaving out useless components). Any suggestions?
Long version:
After a previous screen replacement it would only buzz when attempting to turn on or buzz repeatedly when attempting to charge until I loosened the black screw near the battery connector. I definitely narrowed it down to that particular screw, though I still couldn't say why (the previous tech who replaced the screen may have shorted the battery terminal near there). When he brought it back to me it was doing the same thing again even with the screw completely removed. Within minutes I had it booting just by poking around. Not sure what I did but I had to take it apart and poke around again to get it to come on after making the mistake of turning it off (went right back to buzzing). I'm pretty sure that the SIM card worked because he received a couple text messages when I first got it turned on (phone hadn't been booted in a day). After getting it to turn on I had to leave it on while reassembling, so I put the SIM tray back in when I was done. The owner was watching and asked why the status bar showed an "X" on the signal strength, so I told him that it was because you had to reboot after reinserting a SIM on most Android devices (as opposed to dual-SIM and iPhone devices). Though I couldn't turn off without causing the power problem, I could safely restart. Unfortunately, restarting only gave me the "Insert SIM" message at boot and nothing I could do would get it to see the inserted SIM. I tried many SIM cards but none worked. I replaced the motherboard expecting it to be a solution to both problems but only the power problems went away. The SIM card issue remained even though the SIM slot is built into the part I replaced and the part I purchased is supposed to be guaranteed, tested, clean IMEI, etc. I'm at a loss. I've taken out every unrelated component and replaced the screen again and replaced the battery so about the only thing that is common is the flex PCB with the mic, headphone jack, display connectors, etc running through it. Not sure how that could be a factor, but I'm replacing it too. In the mean time, does anyone have any suggestions for what could be wrong?
Update: A new mic/USB/headphone flex PCB fixed it. I'm not sure how that can cause the SIM card to not be detected, but I conclusively tested and that was definitely the problematic component: No SIM card detected on either motherboard with the old flex PCB, SIM card detected fine on both motherboards with the replacement flex PCB.

Hello, is your LG G2 still working with the new PCB flex?
Thanks a lot, this solution worked for me ?
i've done flash rom on Mtv Slash 3G 512 RAM Tablet, but no sim detected ....& i've followed your suggestion but no solution made...!!!
I had spent more than one month using CM13 based ROM thinking its ROM based issue. but this resolved the issue.
But now no sim issue has been resolved yet no mobile signals are working...
I have a vs980 or the Verizon lg g2. It bought it unlocked and I use T-Mobile. The data worked when I was on the stock os. I then got cm13 and everything worked good accept it wouldnt see my sim card or it would say no signal. And it had no info on the sim card in the about phone settings. So I tried a few other nightlys and nothing worked. I went down to cm12 and still I got the same error. I tried what you said here multiple times and it doesn't seem to help. Any help would be greatly appreciated. Thanks

I found a fix! Go into settings and select Mobile networks. When your in there there should be a "preferred network type" change that to global and there you go. Now I couldn't get that to work on cm13 because the settings would crash when you try to go into mobile networks. But I got it to work on cm12 just fine

I have a galaxy note 3 -n900 I flashed CM13 after which my phone keeps saying SIM removed/inserted... And I can't remove my SIM without taking out my battery. Also my IEMI no. is correct. So no problem there
THANKS!!!
I've spent the last three weeks dealing with various radio bugs and issues, clearing preferences, wiping caches, factory resetting, and installing clean ROMs. All it took is to set the thing into airplane mode? You've got to be kidding me!
Thanks a lot for the solution hackarchive! :good::good::good:
