[Q] Sim Card not found - G3 Q&A, Help & Troubleshooting

I have been using the Korean LG G3 for a while with my AT&T sim card and I did not have any problems up till now. I have pulled the sim card out and put it back it multiple times now and it will still not be recognized. Does anybody have any ideas on what I should do? Thanks in advance!

Try getting a new sim card, and go from there. The issue could be that your sim card is old, or your phone does like it anymore for whatever reason. Alternatively you could try the same sim in another phone if that's an option.

Thanks for the quick reply. I have actually already switched the sim card and it is working on my other phone. So I am pretty sure something is wrong with my phone not the sim card. I have also reset my phone one time. Still nothing. Any Ideas?

You could back it up and do a hard reset this isn't ideal, but it usually fixes things.

Just hard reset it and it is still not working. I think it might be a hardware problem.

Check the slow where you put your sim card into and see if any don't look like they are contacting the card. I wouldn't mess with them, because they are fragile just look.

I looked at the pins and I'm guessing those are the ones in the top of the slot. It seems like two pins to the very right are not touching the card.

I have the same problem in my skandinavian (international (unlocked)) i think it has something to do with the boot speed(fast boot) because i got it to work when i backed my phone up and it rebooted but it always happens again when you just pull your battery out when the device is still on i factory reseted and it fixed it self permanently

I'm having a similar issue as well with the Verizon version. It won't read a micro sim (the one that was activated in it) but it will read a nano sim that I have placed in an adapter to make it fit. Both sims are Verizon, active, and have different numbers. I have no idea what the issue could be.
EDIT:
It seems as if a pin or two weren't making contact with the sim card. After putting a little piece of 3M tape on the sim card, it created enough contact and all is well.

I have the exact same problem if i put a micro sim card it wont read but if i put a nano sim with a sim tray it will work...any solution..

I know this is an old thread, but I wanted to post an update just in case someone else was having this problem. I ran into it with my VS985 a few weeks back. First it was just not reading my sim, but then got worse and wouldn't read any sim I put into it. I was able to correct it by slightly adjusting the pins on the sim reader. I took needle nose pliers/ a knife and gently bent them up a bit. After doing so the phone immediately read my sim card.
I hope this helps someone else if they encounter the same issue.

I have a similar problem. My G3 only accepts and sees one sim card, the one from my old provider. With all other sim cards there is the message "no sim card detected". I tried different working sim cards, no of them are being detected. I switched my provider a few weeks ago and since the problem exists. Before everything was fine.
I also tried adjusting the pins a little bit but so far nothing helped..

OK, I have the same issue: my G3 shows "no sim card" message. The solution is to replace the sim card/microsd slot. However, my phone is not covered by warranty anymore and the incredible honest guys here in Brasilia (Brazil) want to replace the whole main board and charge me for it. So, I'll have to replace that slot by myself. I bought two slots on eBay (search for "lg g3 sim card slot"). Micro soldering is not an easy thing, but there are some videos online that can help. And, if necessary, you can always look for a repair shop to do it for you, providing the piece (the slot). Until the slot replacement, you can try this, it's working for me: I noticed that if you ever accomplish to start the phone normally, you should never power it off to keep it going on! It seems that the sim card is "checked" only at boot time. (I managed to keep my phone connected to the operator for days, but after a stupid friend of mine restarted it, the error came again). To help getting a successful boot, with no sim card errors, I suggest to firmly press the sim card/microsd against the phone while it is starting, from the moment you release power button until the lock screen is shown. This proved to be very reliable, at least for now.

Thanks! This worked for my Sprint LG G3. Kind of a pain to boot while holding the SIM card down but it'll do until I upgrade my phone.
Also, I noticed you don't have to reboot the phone - it will also check for the SIM card when updating PRL. So you can go to Settings->System Updates->Update PRL while holding down the SIM card. Once the PRL update completes it should recognize the card.

Yes, it's hard to hold the simcard through the boot time. Here it takes 30s...
Unfortunately, GSM versions don't have PRL option. And I haven't found another way but rebooting.

Reboot your phone multiple times until it detect the sim card. Once done go to security then set up sim card lock and and enable sim code identification. Now wen you reboot your phone it will ask to enter the pin code to unlock your phone and it will detect your sim card.
The issue is because it rebbot too fast i guess.
For the boot loop issue change your battery.

Thanks all, i set little schotch tape on my card now it can recognize it!
SORRY FOR MY BAD ENGLISH!

The pressing down during startup method worked for me! Took a few tries though, and it only worked when I removed the micro SD and pressed directly on the SIM.

No SIM card error message

Have any Glide owners seen this? My wife's Glide was replaced at an AT&T warranty center recently (home,back,menu, and search buttons stopped working) and every once in a while I see the no network icon on the phone. I go to Mobile Networks and the no SIM card message popup appears. After several power off, take out/put back in SIM card, power up phone attempts the phone eventually sees the SIM card and all is well. I do notice that the SIM card does slide in/out very easily. I put in a small piece of paper to keep the SIM card snug, hopefully that will fix the problem. Anyone else experience this problem?

I had an issue with this before try to tape the sim card in place see if that helps

Tried the tape and still got the sim card error message after a day or so. I went to the AT&T warranty center and they put in a new SIM card. The phone works fine now and hopefully will stay that way. The tech put a note in our acct of the SIM card issue in case it pops up again.
Also, FYI.... Samsung Kies does NOT work when you have the SIM card error message (for backup/restore). Kies just spins the "Connecting..." status forever. I spent a few hours selecting the troubleshoot button that reinstalls the drivers, uninstall/reinstall Kies, installed Kies on another laptop, etc...nothing. The moment the SIM card issue was resolved, Kies connected just fine. The Glide also seems to like to enable USB debugging mode on its own, which disables the MTP connection that is required by Kies. fun.
It would be nice if Kies threw a "Cannot connect, no SIM card detected" message...
I have the same issue. My glide came refurbished and about once every two or three days I will notice that the phone is no longer recognizing the sim card. I have to take the battery out and take the sim card out. Then i have to put the sim card back in and then the battery and turn it on and its fine for another few days. I have had 3 different sim cards and it still does the same thing. AT&T just refuses to acknowledge that its not the sim card.

I have the same problem where ICS will just not read a sim card. I have tried multiple carriers SiM's and none of them work. Does anyone know how we can force Android to read and then request a SIM. It is not a problem of the SIM not being seated properly since it was working directly before the ICS upgrade and when I downgraded the first time it read my SIM without a problem.
I have not yet had any problem like that, I have had issues with data and wifi, but later found that it was the software I used before for battery management had an update that shut off those services and have fixed.
SIM card errors though, I only got 1 once but that is because the simcard holder in my phone seems loose and it wiggled out once and after that was nothing a gentle squeeze couldn't fix.
Samsung SGH-i927:
ICS Leak I927UCKL1 4.0.4 Stock
CWMR Touch v4.0.0.1
Keyboard fix
Superuser 3.2r3 ARM Optimized
LiteKernel v5.2
quick update, so far so good with the new SIM card. no sim card errors
spoke too soon! got the sim card error this evening. went to the AT&T warranty center again and got a replacement phone. this one better work.
SIM card error mesage again with phone #2. so far:
1) new phone, same SIM card, same battery
2) same phone, new SIM card, same battery
3) new phone, same SIM card, same battery
I'm starting to think this might be a cell tower issue since the other problem with this phone is that the phone would sometimes not ring or show any missed calls. maybe now it throws the SIM card error instead??
the mrs is going to go to the warranty center again to try to get a new battery and charger. we'll see.
final summary, new battery and still get the sim card error. AT&T is sending a Galaxy S2 skyrocket as a warranty replacement. My wife tried out swiftkey 3 and is willing to make the jump to a touchscreen keyboard.
Sorry to bump an old thread, BUT, a factory reset fixes the issue. My wife had this problem. It occurs if the SIM card is ejected by accident for any reason while the phone is on. The simcard does not lock in at all so I can only assume she bumped it just right. I got a full replacement phone from ATT, and while messing with it while on, the simcard fell out. After turning it off and putting the sim back in, the same problem occurred on a brand new replacement. A factory reset solved the issue.
I was googling about this and saw this thread. Figured I'd add my 2 cents, and what solved it, but I am still replacing the sim just in case.

Sim card slot pins broke.. any hope?

Well, just as soon as I bought an unlock code and attempted to pop in a different network's sim card, the slot tried to chew up the sim card.
Once I was able to pull it out, the pins (or other metal objects) came out with the sim card, in pieces. Now, no sim cards are recognized.
Any hope for this? Or has my Xperia Play been delegated to a gaming device, without cell phone capabilities..
You can attempt soldering the pins back in and pray it works..

I see they sell new sim slots, but I don't know how to solder at all. I've replaced the screen and digitizer myself on this phone already (so I'm not completely afraid of working on it), but soldering is beyond my skillset.

[Q] No SIM card problem..PLEASE help!!!

OK, so I've searched these forums, and various other forums, quite extensively to solve my problem here. My buddy purchased an ATT Samsung Galaxy S3 off of a friend. He unlocked the phone, using the free method mentioned within these forums multiple times (entering digits in to the dialpad, going through menus, etc..). With that, he was able to use his T Mobile Straight Talk SIM card to use Straight Talk's services. On a suggestion from me, I told him to save some money, and switch over to T-mobile directly.. get the $30 a month plan. He did.
When he set up his sim card from straight talk, he had to cut it to fix the S3. It worked fine, but when he removed the sim card, he thought he could have damaged the sim card holder. Lo and behold, inserting the T-mobile sim card is netting a "No Sim Card.. Emergency Calls Only" message. I believed possibly he unlocked his phone improperly, based upon the fact that, apparently, per these forums, Straight Talk doesn't require your phone to be unlocked? Regardless, we re-unlocked the phone, using the free method mentioned within these forums, but still the sim card doesn't recognize. We tried my t-mobile sim card, which works fine in my nexus 4, and that didn't recognize.. but his sim card DOES recognize in my phone. We tried a verizon sim card, and that doesn't recognize. We have NOT tried an ATT sim card, but he's going to do so shortly, to see if that recognizes.
Thinking this could be a software issue, I wiped his phone's cache, data, etc.. and reset the phone to factory defaults. Still the no sim card error. So he bought a new sim card holder off e-bay, removed the back, removed the old sim card holder, put the new sim card holder in.. still no sim card error. Still doesn't work with any of the sim cards we've tried.
I then wiped the phone yet again, rooted it, and installed cyanogenmod, thinking possibly that it was software related still. Still, no sim card error. I took the phone apart, cleaned the contacts with a q-tip and denatured alcohol, cleaned the motherboard, cleaned the plugs for the sim card holder... still no sim card error.
So as far as we can tell, the phone is unlocked, rooted, has been tried with a custom rom, stock rom, and the stock rom that worked perfectly fine one week ago. We have replaced any potentially bad hardware (although, potentially, the new hardware could ALSO be bad I suppose). As far as I can see, this is not a software issue, nor is this a hardware issue.. yet, it still doesn't work. I'm really out of possible solutions at this point, and I implore the help of these forums to give me a lead or something for what can be done. This is a nice phone, and my buddy's not that well off; he can't really afford anything other than a flip phone, and he spent a good chunk of cash on a glorified tablet at this point. Please help! Thank you!!!
EDIT: I also tried cramming a piece of paper in to both the old sim card older, and this sim card holder, to ensure the contacts are touching properly

my note 3 tmobil not reading my sim card

Try doing a factory reset.
If it's sold on ebay that means that it can be replaced.

Most likely it is and it will involve soldering.

Did you try simcard in diff phone first or try another simcard in the phone? Because ive had simcards die before. Might wanna try before you think about messing with internals
i was getting a "cannot detect sim car" error and the phone rebooting the other day. I took the sim card out, blew in the area and put sim card back and haven't had any issues since. Maybe try this?

LG G3 not detecting my SIM (or number?).

hello everyone
recently my lg g3 started giving me 10 Seconds then reboot (after SIM card became not detected). this happened maybe once or twice a day then it gradually became worse till the point of not detecting my Sim at all. I put my SIM card in another phone and it worked just fine.
i then tried my Sister's sim and it didnt work too but my brother's and dad's both worked. any idea what is causing this problem? could it be Software related?
things i tried to do to solve the problem (but didn't work):
1-transfer my phone number to a brand new SIM card.
2-clean with the SIM reader with medical alcohol.
3-put a folded paper between the SIM card and the SIM card reader (worked for a moment then suddenly stopped for ever).
4-hard reset the phone.
any idea on what could be the problem?
EDIT: through my search on google, i could only find one thread on xda related to my problem and i didn't notice the one bellow mine.
but the one mentioned earlier is not identical to mine so i'm keeping this thread.
You probably need to reflow the sim card reader.

shouldn't the problem be with the pings touching the sim or am i missing something? i will try to melt and freeze the solder on the sim reader pins that are connected to the motherboard and post the outcome though.

Most likely the problem is sim card slot not touching the motherboard correctly.
Qcn problems. Try to backup your qcn (please googel it how to backup qcn). And then clean partition that contain your imei, radio and esn (google it how to do it). Restore again with QPST. Hope will solve your problem.
