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.

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)
I got a Tmobile compact IV (diamond) sevral weeks ago in nerthlands. and flash the rom successfully.
However ,there is a boring issue that the machine always went to death when the TMOBILE sim card inserted in. while i use other sim cards it can work!!
I really dont know what is the hell going on with the fuking machine. I even unlock the sim lock and pay for 15 euros!! The mater still exist~~
forgive my bad english . and anybody can help me ?
maybe you have a faulty sim card?? try another t mobile sim card - if you unlocked it and all other sims work it should be fine
Up to what state it boots up before dying.
i also got my t-mobile phone recently.
when i inserted the t-mobile sim card in, it froze the mobile while searching for network...
t-mobile told me that is because my sim card from t-mobile is not activated yet and it usually takes 48 hours before I can use it.
when did you choose to "activate your contract"? did you choose to activate it immediately?
you can try the t-mobile sim card on other phone. it must also show "limited service".
I guess the problem is not your phone.
Dear all
I bought a phone which is SHARP SOFTBANK SH934 from Japan. The problem is when i bring back to my country - Malaysia. I notice that this phone cannot detect the network right after i changed to the local SIM card.
I have search through the websites and videos. Most of them are use another sim card with a chip on it that you attach to your GSM sim card and insert into the phone. It's called either a 'Hypersim' or a 'Turbosim'. But this thing is costly.
Does anyone know the another way to settle this problem?
Very much appreciate!!
does anyone know?
hope to get help deeply..
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.
Sent from my phone
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...
Okay, first a little prespeach. I bought used LG G3 phone (which is working perfectly btw) in my born country (Bosnia), and used my SIM card without any issues, signal always was full and even I used internet without any problems, that was like 1 week long. Cause I study in diffrent country (Croatia) and I had to go, I inserted my other working SIM from that country and signal appears like 10 seconds and than searching for signal. First I thought it was damaged PIN connectors but than I insterted again my SIM from my born counry and it again was working fine for whole day. Then I went to that carrier (in Croatia) to replace my SIM card (I thought maybe SIM damaged), but when I inserted that new SIM, everything was same. I tried to buy other carriers SIM cards from Croatia, but everything was same, signal is there for max 10 minutes and than there is sometimes warning sign that said: Please insert working SIM card and phone must restart and when it restarts and again searching for signal. Currently I'm in Croatia and using my SIM from Bosnia (in roaming) which is working perfectly without any signal drops and searching signals. Before this phone, I used S3 Neo dual SIM and both cards worked fine without any problems.
So, my problem is not damaged pins, cause my SIM card is working perfect (from Bosnia) but any SIM card from Croatia is losing SIM signal. And my phone is unlocked (I think so).. Any advices what to do, or to go to the phone repair shop? Thank you!
