suggest you check the direction of your sim card insertion, and insert in the correct way

well, theres a good chance its a bad sim card. i see that fairly often. the other thing is it could also be a bad sd card. try a different sim card, and a different sd card if you can. did you try factory resetting it? also... where did you get it and why are you sure its not rooted?
Get a new sim card for your carrier

P970 can't use any SIM cards

My Optimus Black was working fine for about 3 months. Not sure what happened, but it started showing no network/signal. It's a completely unlocked phone. I tried a friend's SIM card and the first time it wouldn't work, but I tried again a few days later and it worked but had a pretty bad signal. Now it won't work no matter how many times I try. I even bought a new SIM card/number (I live in Asia) and it won't work.
I had Android 2.3 and thought maybe something got corrupted, so I wiped and reinstalled, but same problem. I wiped again and installed Mokee OS, and same issue. (By the way, after using Android 2.3, switching to Mokee is so much nicer, although it's in beta and still has some bugs.)
The 6 gold SIM connectors look fine. I used a SIM app and it recognizes the SIM card and its carrier, so I think the card is being read OK.
I live on a small island, so sending the phone back to LG or taking it back to where I bought it (Bangkok) would be a huge hassle. Does anybody have any ideas on things to try to fix this? I'd really appreciate the help.
Can you return to stock rom (rooted or not, as you want) and then tell me if you see something write in LG lockscreen (I'm thinking about LG Security Error) ?

please look into menu/settings/apout phone/status/imei
it is normal?

The first time i wiped the phone i went back to Android 2.3, but all that the lock screen said was "No service". Usually it says "DTAC" when I have service. Is that what you mean?

I think everything is normal. It has an IMEI number. It is 15 numbers. It also has an IMEI SV number that is 16 numbers.

No if the SIM card isn't used that phrase is normal. I got a problem like you but it was written "LG Security Error" and I had to use Smartflash tool erasing cp and then recover my imei. But it doesn't seems that you have the same problem. "/

Thanks. I'm going to try flashing the stock rom. I can't find any good threads about recovering the IMEI. Everything I am finding is about Samsung. Do you have any links you can share?

I flashed the new rom and erased the CP data. still no phone service but i haven't reset the IMEI yet. having trouble with that step. i'm not sure if this is going to work though, my problem seems different. my phone can see my SIM card, but i just don't have any phone service with any SIM card. the sim cards work fine in other phones.
try a sim without pin code
and flashing with smartflashtool (erase entire cp) doesn't works?

i don't think my SIM has a pin code? I'm not sure though? There's only one type of SIM you can get here in Thailand. You buy the SIM from a phone shop or 7-11 and add credits to it. I've never seen any other type of SIM card.
Yep, I used smartflashtool and erased the entire CP (had to enable with Windows Enabler). Now there is no IMEI and still "No service".
Retry or by changing baseband now...there was a tutorial in optimus3D threads i think
Or in this one itself
Change the baseband

[Q] my Samsung gt-i9000 wont read sim card

Hi im shure this has been written about before, but I'm trying a new tread
My Samsung galaxy gt-i9000 wont read the sim card, and all the post I've read, says it is most likely software fault,
But I've tryed installing stock software with no luck. I can call emergency calls I can get connected to wifi
Follow this link, as it described what I have done
http://forum.xda-developers.com/showthread.php?t=2770240
Anyone who has suggestion of what I can try?
You've likely lost your imei. If you don't have your efs folder backed up then you're gonna need to flash with odin back to stock.

Hi and thanks for reply
When I push *#6# I get an imei number, so I guess thats correct.
However, I think I found the problem, it seems that it's missing one of the pins who should connect to the sim. My sim slot has only 5 pins like this:
Top
''
'''
Bottom
But ive seen on pics, there should be
Top
'''
'''
Bottom
I ordered a replacement part of ebay, so I hope this fix it.
Anyone who knows how many pins the sim slot should have?
