I got to say, your panic is not going to help. First I want you to take a deep breath, and relax. Now, in order for us to help you. We need to have more information. More specifically, the following: Do you have roo. boot loader unlocked? What carrier are you using? What ROM and kernel you're using? Is your sim good? Are you using a micro sim? What radioband you're using? Is your sim card adapter slot damaged? Is your imei bad? Now you need to put this in a detailed explanation with what you have done with your device up until the point in where your phone stopped working.

stock room,one week old device, no root or nothing similar,the phone doesn't show imei number just blank window (*#06#)

If it's stock and all you did was do an OTA upgrade to 4.2.2 have you tried talking to your carrier? Being only a week old I would use their assistance to your advantage especially if you did not unlock/root the device. (not sure how you came across the sim card, if it was sold with the phone like it was with mine at T-Mobile, or if you just got the phone and then used a sim from the carrier).

but t mobile will send nexus to repair's for a month so do not want to be w/o my phone for so long.I'd like to solve it home...

What was the source of it? OTA/official update? If so, and if you did not rooted your phone - go to provider/service.
Most likely, your efs partition is screwed up. If you do not have backup - poor chances for restoring it.

OTA = off the air, so you have the official ROM. In rare cases, efs can be damaged by that. Call nearest Sammy Service Center.

No solution so far !! Need help guys

[Q] No sim card detected

Hi everyone,
I messed a bit with my d802 and finally i used the lg support tool to get it back to stock, but now it can't read my sim card all of a sudden (no sim card inserted).
So the question is where are the sim card files, in the kernel or the rom or the baseband ? and how to get them back so it reads my sim card.
I'd be happy to bring you more info on the problem.
Thanks in advance.

I had the same problem, reflashing the 10B firmware then upgrading to the OTA 12A fixed the issue.

Did you sort this?
If not try this
Power OFF the phone. Remove the SIM card completely for at least 1 minute.
Re-insert the SIM card, Power ON.
If it works, I'll tell you why...

OK - good. This is a fairly common "problem" when making significant ROM changes - but doesn't always happen.
In basic terms...
When the phone is powered OFF, it isn't actually completely OFF. Some "parts" are still powered. The SIM card and its register are "parts" that remains powered and the register is sometimes overwritten when a ROM is flashed. This means when the new ROM boots, the SIM card and the register are different, hence no network as the phone assumes a fault.
The SIM card needs to be removed with the power off (NEVER with it on) so the phone detects a SIM swap and the register is refreshed.
TIP: Before flashing a new ROM - always remove the SIM card (with the Power OFF).

No SIM CARD after official lollipop stock rom update
Hi,
I have updated my LG G2 F320L (Korean Version by UPlus) on Lollipop successfully.
But now my SIM Card is not detecting. I am in Pakistan and dont know what to do now.
I tried to restart the phone with no sim and with sim and also flashed the same stock rom again but still no sim card.
I also tried to put the following codes i.e. for IMEI *#06# and for SIM Unlock menu 2945#*320# which didn't work too.
I also did factory reset many times with sim and without sim.
Tried to do rooting throguh Towelroot and Stumproot but no success.
Dear All, Please help as what might be the problem.

Unfortunately I don't have a solution yet, but I wanted to point out that I am in the same situation ATM. German lg g2 though. Please any new input would be highly appreciated.

Issue Resolved
Hi I took the phone to the android expert in mobile market in my area SADDAR AREA-RAWALPINDI CITY-PAKISTAN. Where he highlighted that the ROM, Baseband and Radios where not compatible as well as my phone had some EEPROM problem as well. So he hooked a small box like USB device and pushed the ROM into it via OTG along with the new stock ROM. Now my phone is working perfectly fine and I am more than happy and thankful to the expert. My current stock ROM is lollipop version: 5.0.1

I know this thread is hella old but, I stumbled upon this (after returning to the G2 temprorarliy - had it back in 2013/14) after restoring a stock LG ROM backup and it wasn't recognizing my SIM card. Anyways, this method worked for me to get the phone to recognize my SIM. Thanks for posting this.

Samsung Note 3 doesn't want to recognize/register my SIM

I'm not a 100% sure how this problem occurred, I believe it was after flashing an S5 custom rom called: "RC Elite S5 Port V16" To my Samsung Galaxy Note 3 (N900W8). From what I was reading it was a ROM that "converts" your note 3 to a note 4 or s5, while still having all the Note 3 features. Another possible cause is trying to use RegionLock Away.apk by Chainfire to essentially(unlock) the phone. I feel like this is the main cause though as this affects the modem on the phone. This isn't the SIM as I tried it in another phone and works fine with calls and texts.
My phone doesn't want to register its mobile network anymore. When I try to make a call or text it says:
"Not Registered on network"
I was reading online for about 2-3days now for possible solutions that can cure this. Such as:
1. Going into Mobile Networks settings and manually register [failed, details below]
2. Going into Mobile Networks settings, hold home button for 2seconds and then hold power button + home button for 15seconds [failed, details below]
3. Taking out battery while the phone is on and remove the SIM card, clean it and re-insert [failed]
4. Factory Reset [Failed]
5. Wipe Storage and re-flash stock ROM [Failed]
Options 1 & 2 do not work because when I try to access Mobile Network Settings I get this:
"Insert SIM card to access network services"
The SIM card is inside the phone though...
So what I did is found a mobile network options shortcut "program" from GooglePlay Store and installed it. It allows me to access the menu, which is great! Now, when I try to register the SIM card to my correct service provider (BELL CANADA)...it will make me wait for about 1-2minutes before I get "Unable to register, try later" error.
I tried the factory restore with a stock 4.4.2 ROM from Sammobile and the issue is still there.
Is there anything that anyone knows that can help me resolve this problem? I tried EVERYTHING i can possibly find on Google. I've seen posts of people suggesting to flash a modem.bin file with Odin but I don't know where to get those files, nor what to look for in terms of modem file "types".

I tried region unlocking it with RegionLock Away by Chainfire. I would like to say afterwards this issue occurred but as far as im concerned, using a TELUS Mobility sim card activates the network pin unlock. So i'll be going with no, it's not unlocked.
I currently have a Bell LTE 4G SIM card installed on the phone. If you check the photos there it shows I have a full connection but unable to make calls nor access the mobile networks menu.... =/
I can provide pictures on the error messages if you'd like.

Do one thing.
1. Turn off the phone. Take a out the simcard and battery for some min.
2. Add the battery only. Turn on the phone and factory reset your device (Settings > Accounts > Back Up and Reset > Factory Data Reset > Reset Device > Delete All/Erase Everything.)
3. Insert SIMCARD without turn off the phone.

They there! I tried to follow all the steps to the best of my ability but it seemed that didn't work. For 1, the note 3's sim card slot is blocked by the battery so i can't take it out without turning it off. In addition, after only inserting the battery and performing the factory reset, I decided to test it and the issue is STILL there even though a sim card isn't even inserted AFTER the factory reset. Same error messages as if nothing ever happened, even shows full bar reception even though nothing is in there. =/
This is the most unique problem I have ever encountered myself. I really don't know what to say...

Bumping.
After some more research I was wondering if you reflash the stock firmware back, does it effect the EFS partition at all? Cause if it doesn't I believe I installed a faulty EFS partition accidentally which results in the broken connection.
Any way I can get a backup of an EFS file that I can flash?
Thanks.

Bump. This issue is driving me nuts.
Thank you in advance.

Thanks in advance for the replies.

I had this same problem earlier (for a note 2) in the week where it just wont register any sim card.
In my case i think the problem was that i did a full format before flashing which probably deleted the EFS folder.
I tried so many options and eventually managed to resolve it by following the following instructions to restore the stock firmware.

Hey there!
Thanks for your swift reply! I had already did the Samsung Recovery via Kies 3. Do you know if I reflash it that way that the EFS folder would get flashed as well? Because after doing those steps the issue is still there, after about 3 firmware recovery flashes. xD
I didn't even think about backing up the stupid EFS folder otherwise I would have. I was looking at this

Sim Card not working in Samsung galaxy S4 i9500

I am using Samsung Galaxy S4 i9500 (Exynos) and I'm facing a problem from many days. The sim card shows Emergency calls only whenever being inserted.
When I try to open settings a pop comes up saying "insert sim". I tried factory reset, wiping cache and dalvik cache, even changed ROMs but no solution. Can anyone guide me what should I do next to get rid of this issue?

Does the sim work in another phone? Does any sim work in the s4? If the answers are yes and no, the sim reader may be damaged.

your efs partition might be damaged, try typing *#06# in phone app, if you get the right IMEI then your efs is right and it's a hardware issue as mentioned above, if you get zeros and ones or "null" or any unusual answer then your efs is corrupt.

I got the right IMEI, seems like its a hardware issue

Fortunately, replacing the SIM tray is easy to do. Just make sure to reuse the foam pad attached to the top of the original tray's connector. The back of the phone presses against that pad, ensuring the connector doesn't loosen during use.
