Problems with new SIM card LG G3 - G3 Q&A, Help & Troubleshooting
Hi there,
I am a so far satisfied owner of a G3 but since 10 days I have been having an issue with my G3 and I wanted to ask around if someone here has an idea or some thought that could help.
My situation is the following:
About 2 weeks ago I switched my mobile service provider. When my new SIM card from my new provider arrived I tried the SIM card in my G3 but there was just the massage "no sim card found" and no possibility to type in your PIN. So I thought maybe I got a defective SIM card, it happens. I ordered a new one but the problem remained with the new card in my G3 aswell, still no pssibility to type in my PIN. So I tried troubleshooting and started trying the SIM cards in diffrent phones. In other phones the SIM card from the new provider worked perfectly and I was able to type in my PIN like it should be. When I tried putting other SIM cards in my G3 (from my Mom, Dad etc. and also from different providers) none of them worked in my G3. Even my sisters SIM card from the same new provider AND she has also a G3. So far it seems that the my G3s SIM card reader is broken.
The weird thing is that when I put in my G3 my old SIM card from the old provider the prompt to type in my PIN appears as normal as ever. If I type in my PIN the phone accepts the PIN normally. There is just no reception which is normal because I am not with my old provider anymore. I also have to add that the phone appears not to have SIM lock. I bought it from a private seller but he bought the G3 with a vodafone contract and I was with O2 at that time and the phone worked perfectly. Just until I switched from O2 to Congstar (Telekom) the problem began.
So I thought I just send it back to LG because I still have warranty on the device. The phone is rooted so I need to admit that it was not that clever to send the phone in without rolling back the rooting. Today I got a letter from the repair service from LG with an estimate of cost which means no surprise, no warranty for me. You guess right, the reason is the rooting they write they need to change the whole mainboard. For me this sound like plain bull**** because on the document they send it seems like the first thing they check is a rooting and if the device is rooted then thats the cause. But ok it was pretty stupid from me not to unroot it, I know.
Now I wanted to ask you if someone had a similar problem with their G3 or has an idea what the cause could be. Like mentioned above with my old SIM card the phone worked normally. Just the new cards and all other cards, even another O2 card did not work. Is it possible that just one and only one SIM cards gets accepted from the phone?
Sorry for the long post. I am thankful for any advice.
Best regards,
Patrick
I'll have my phone back tomorrow. If someone still has an idea I would be very thankful about some thoughts or suggestions.
Thanks!

It seems your phone is Sim locked.
You need to find the unlocking code that you need to put in the hidden menu.
Google for LG G3 Sim unlock.

Hi,
thanks for your reply! Iam not sure it is because of sim lock- Because the phone came with a vodafone contract but when I bought it I was with O2. And with my old sim card from O2 the phone worked perfectly. Weird is that when I put in a different O2 sim card the pin prompt also did not appear. Same with any other sim card ...
Thanks,
Patrick
Or did maybe someone have a similar experience with a different phone?

Hi again,
I tried some more things but still nothing helped.
The things I tried were:
- unrooting the phone and factory reset
- reflash radios
- try completely diffrent rom (CM)
Still I have no idea what the cause could be. Maybe the sim card reader is just broken. Just weird that it reads my deactivated sim card.
I would really appreciate it if someone has an idea or some similar experience..
Thanks!
You can buy an unlock code for 3.5-4€ , works for any LG G3 variant
Try it
Ok, thanks! I will try it!
So I just looked at what I have to do and tried the combination 2945#*855# to see where I have to type in the code. The thing is when I choose any one of the appearing options like netlock etc. the phone says "this phone is permanently locked" and there is no possibility to type in any code...
How the hell is my phone completely locked...

unlocked phone suddenly says 'invalid sim'
I broke and replaced the screen in my unlocked upgraded flashed-ROM wallaby and the unit now starts up and reports invalid SIM. Is there any solution or should I re-flash the rom again and see if that works, hope for the best?
Try the SIM in a different (unlocked) phone, to make sure the SIM isn't fried. If the SIM is fried, you can get a new one from your provider. SIMs do get fried sometimes -- it happened to me a couple months back. Fortunately my provider (Cingular) has a shop just down the road from me, and they burned a new SIM in 5 minutes.
I apologise, I should have said Sorry, I should have said, it does work in another machine and as I said, it did work immediately I used the xda flashing process to upgrade the ROM in this very unit before I dropped it. Everything else in the new ROM seems to work which makes it infuriating that it wont recognise the SIM. I even tried calling T-Mobile and asking them if they could see the SIM on their network and they couldn't. (I even have one of those SIM copying devices they send you free for some unknown reason when they want you to upgrade your service to some kind of higher level SIM card. I was wondering if I should try to use it again but as mine does work, this, like the whole copying device, seemed a bit academic)
Simcard stopped working (Bizarre case)
Today out of the blue my sim card stopped working. 1) I tried the simcard on my friend's phone, it works fine! 2) I tried my friend's simcard on my phone, it worked! So for some reason my phone rejects my simcard. I got desperate and decided to do a factory reset which didn't help. My phone is running stock android and it's perm rooted. I have no idea what to do. Any suggestions please? Thanks.
If you sim stoped working talk to your mobile provider Sent from my HTC Vision using Tapatalk
My sim card works on other phones, so I think it's something else.
Oh... sorry I misread. It must be a defect or something. Have you tried flashing other roms. If it keeps happening get it replaced Sent from my HTC Vision using Tapatalk
So I spoke to tech support and they said they will send me a sim card free of charge this time. But the guy informed me that my phone is burning the sim cards because it wasn't designed to work with HTC devices, so it's reading the simcards improperly ending up damaging it. He said I need to modify some code on the phone so it wouldn't burn the sim cards. Any ideas?
Now the sim card suddenly started working........... that's too odd.
[Q] LG G3 F400L Detects sim card but no Network
Hello, I had searched a lot for an answer for this problem. I bought a LG F400L on ebay yesterday and when I put my Vodafone CZ sim card inside it asks me for my pin code but afterwards I dont get any signal. It just looks for signal but actually doesnt connect. Phone is unlocked, I tried choosing networks manually and nothing. I have no idea if this could be sim card issue (Which I just replaced, so this one is new) and I should get another one or Sim card reader problem? Im really desperate now as I have no other phone at the moment Please Help.
[HELP] No sim card - Emergency calls only - LG G3 D855
Hello guys, i have some issues with my LG G3. As the title says, the phone isn't reading the sim card, sometimes, it's working just fine, for a couple of minutes, then, a countdown begins, saying "No sim card detected", in 10 seconds my phone will reboot and that's it. "No sim card detected" again. Every other aspect is working just fine. Things i've already tried: - Switching sim card and switching the sim carrier. - Replacing sim card & microSD reader. - Pressing down the sim card at the startup. - Hard / Factory reset. All of those for nothing. I'm thinking is an software problem, is that possible?
Exactly the same problem!! Has been in and had a new sim tray, worked for 3 days then back to no sim, no service, emergency calls only. Taped down sim, changed sim, factory reset, nothing!! I am so frustrated! It's only just over a year old too so I'm not due an upgrade and it's out of warranty.

Click to collapse unfortunately, this has nothing to do with our problem, my g3 shows the correct IMEI. will try to heat the area of the motherboard located behind the sim card reader with my heatgun. some guy got it to work like this ( though he did not show any actual evidence supporting his claim, and neither did i ask for it)

LG H815 sim card not recognised
Hi guys, Don`t know if it happened to anyone else but maybe someone can help me. I bought an LG H815 from Vodafone UK > 2 years ago and unlocked it with an ebay code. It worked just fine until February this year ,1 month before expiring the warranty. I sent it to LG UK and got replaced by a new one. The new one was also locked I unlocked it again using an ebay code but after few days I started having problems with the signal. I was getting a message "no sim card" and my phone restarted. First time I thought that the sim mooved and I put it back but it kept on doing like this. The thing is sometimes is working for a few hours sometimes it`s not working at all. Tried different sim cards same thing happened with the phone, tried my sim in different phones was ok. I also did a factory reset but nothing changed. I asked the guy who sold me the unlock code and he said it might be the sim bracket. What should I do ? Should I try to flash another kdz or to install Lineage ? Or simply go to a phone service ? Thank you very much for taking your time to read my post.
