Sim card isn't working :( - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

Hi,
Not long ago, I installed Android 4.1.2 (Germany) on my Galaxy Note I (N7000XXLSA_N7000OXALSA_DBT).
The sim card worked something like 2-3 months and then it didn't work.
I changed few ROMs and it didn't help.
Do you have an idea what happened?
What can I do?
PS: The sim card works on other devices.
Thanks,
Shahar :victory:

a) Check your IMEI. Is it still the original number or does ist start with 004999....?
b) Try to change your SIM Pin and test if starts working after.

AW: Sim card isn't working
Now you don't have your own IMEI anymore. You have a developer IMEI.
On ICS and JB official releases you have to change the Sim pin after each restart.
Alternative: use my Pristine Rom. This has a workaround and your Sim will work.

his rom should do the trick.
pin is number when you start your phone and you have to enter a four digit number. Then your phone registers on the network.
If you are missing the screen where you enter your pin you can get it back. http://forum.xda-developers.com/showthread.php?p=25953317

Phone will not recognize sim/ imei "Unknown"/ baseband "Unknown"? *Updated*

Phone will not recognize sim/ imei "Unknown"/ baseband "Unknown"? *Updated*
Updated title because problem has now changed.
current problem--
Phone is stock, randomly stopped getting signal factory reset phone using keypad, now phone will not recognize sim card, the imei is blank and the baseband is unknown. Tried reseating the sim, and powering on off.
initial problem--
After having a problem free note for some time now it randomly stopped working. I cannot make a call/ text or use data but the wifi works and the phone functions outside of those uses. When making a call I get various errors in the form of Mobile network not available/ Not registered on network and when i go into mobile networking settings> network operators it takes a while when searching and tells me to either try again later or gives me a message "error while searching for networks." When i take the sim out all together I get bars of service but when the sim is in it either gives me a circle with a line through it or a empty signal bar triangle.
I called straight talk customer support as i thought it was a problem with the service and they told me I had a bad sim card. I have since checked the sim in another phone and it works fine. I have tried multiple working sims in other phones and no luck in mine. The phone appears to be recognizing the sim as the apn settings are adjusting based on what sim i put in. I have tried to take out the battery, take out the sim, factory restore but nothing seems to work. I have also checked the imei number online to see if it was blocked or something and it said it was not. I took it to a local phone repair shop but after toying around with it for a hour they didn't know what was wrong, so here i am, hopefully someone can point me in the right direction. thanks.
May be the phone is network locked. is it asking for some kind of key or pin anytime or when restarting the phone?
where did this begin to happen?

After doing a factory reset using the keypad, *2767*3855#, it now says it doesn't recognize my pin and when i type *#06# IMEI comes up with nothing after it. Also, my baseband is now unknown. Is my imei corrupted or something?
Are you on a custom ROM...do you have imei backup... did you try to reseat the sim card

I know the sim isn't the problem as it works in another phone.
You may want to try flashing stock GB with PC Odin...then with stock GB recovery do a factory reset.
Don't do anymore factory resets if your on ICS and completely stock - you will kill your device...see the brick bug sticky

I'm assuming i have to root my phone in order to look at this folder? I'm looking into this now.
yes.
when restarting phone do you get the password prompt for the sim pincode, could be sim is not registered?
Anyways a stock phone should not do this. Its a case for customer service to fix efs. That appears to have instantaniously corrupted(!) first case I have ever seen of this.
Almost cannot believe it.
Without sim, is the imei there? I am suspecting your emei was gone before which you never noticed then. Is it even a new phone?
note rooting might void warrantee, so be careful

Well, I'm not sure about the problem; if you are on a custom rom, it might be because of that, or incorrect flashing. Try using another ROM, and if problems persists try Stock ROM meant for your region. (it might be possible that you flashed a ROM for a different region and because of that you might have a problem..)
AND NEVER POST YOUR IMEI NUMBER ONLINE.

I'll try with stock rom.
I flashed original stock rom on the device, but the problem remains. Does anyone know the solution, I am going crazy

pop your sim card out for 15 min. then put it
back in your phone.
In the second pic it is clearly showing 1 bar of signal
So how can you say sim is not being detected
No way out here

Did you notice the the SIM symbol with question mark inside it?
The phone acts like there is no SIM card inserted when it is inside all the time.

[Q] Invalid SIM card error/SIM network unlock PIN request on boot I9305

Okay, I posted this question in the I9300 Q&A section by accident (was a bit distraught, didn't read the section title properly), but for some reason a mod appears to have deleted the thread instead of moving it, so here it is again in the correct section.
So after using my I9305 for about 8-9 months now, I woke up this morning to find my phone nonoperational. The phone requests on boot a "SIM network unlock PIN". If this window is dismissed, the pulldown notifications drawer states "Invalid SIM card" with subtitle "Network locked SIM card inserted". Quick Googling reveals that these notifications and errors typically show that a phone is locked to a specific carrier. Now that's understandable, but this phone is unlocked, and I hadn't even taken the SIM card out until this error occurred. The SIM card works just fine in another phone.
I've tried rebooting the phone (first port of call), and using the code *#197328640# in the dialer to SIM unlock as per this post (but I didn't have "[4] NW LOCK NV Data INNITIALLIZ" as an option). I tried using "busybox chown 1001:1001 /efs/nv_data.bin" in terminal emulator as root, after seeing this post, but it came with an error of "chown: /efs/nv_data.bin: NO such file or directory". So... how bad do things look? And no... I don't have a backup of my efs. =[

Since then, I also tried *#06# in the dialer, and my IMEI is intact.

Are you totally stock rom or custom?
Stock standard 4.1.2, with CF-Auto-Root.

Maybe try flash a stock pre-rooted rom by lriquidperfection with odin and try the *# again?
Tried various different stock ROMs and factory resets, nothing.
You need to flash a 4.1.1 ROM, or at least a modem from such a ROM.

Not sure why doing anything with the battery would be in any way related with the SIM. I also forgot to mention that I had already tried cleaning the SIM card at the start with alcohol. In any case, the SIM card works fine in another phone, so it appears that there isn't problem with the SIM card. In any case, I managed to RMA the phone, now the long wait to get it back...

i not joke with you
i have same problem with you 5 month ago with copy battery
Got my phone back from the shop today. Kept an eye on the shipping tracking when I sent it out, and they sent it back out half a day after they took delivery, so I'm guessing they used a SIM unlock code since it's definitely my phone that I got back. Didn't have to pay anything, so I'm happy. Still not sure why/how the phone decided to lock itself though...

[Q] Phone not recognizing sim card or providing IMEI

Hi,
I have owned a factory unlocked Galaxy Note GT-N7000 for about 9 months now. I have since rooted it but kept it on Android 4.0.4 and recently put a Speakout Wireless sim card in it [it's a canadian carrier that re-sells Rogers Wireless] (I used to have a TIM (italian carrier) sim in it).
It worked fine for about 3 and a half weeks. Then, suddenly, it refused to recognize the sim card. I ordered a replacement SIM card, and it did not fix anything either.
It also displayed some alarming other signs that something really isn't working:
If I hold down the power button, instead of displaying the normal power menu that allows me to switch to airplane mode, reboot or shutdown, it now shuts down immediately
If I enter *#06# to get the IMEI number of the phone, the IMEI window appears, but it's empty
If I enter the settings menu and phone informations, the IMEI number is shown as "Unknown"
I am really at a loss as to how I should proceed now
easy hack it with haxor talk thought terminal to other dimension...
no efs backup = your screwed.
so dig in and find a 5 part rom with efs. img, use the freaking search and pcodin it onto you phone, drketan guide way.
that gives you generic imei enought for service, unless your country or provider blocked it lmao

One question tho: point #1 says to look for "/dev/block/mmcblk0p1 on /efs type ext4(rw,nosuid,nodev,noatime,commit=20,barrier=1, nodelalloc,data=ordered)". Not such line is present in the output of the command on my phone. Does that mean that I should proceed with point #2 or not?

I've done point #1 and #2, and the phone started working again (I was able to take calls, etc) but the IMEI was a temporary 0049 etc number.
When I did point #3, it stopped working, it reverted to the blank IMEI issue detailed above.
I have now redid point #1 and #2 and it works again with the weird IMEI. What am I to do now tho?

The only way to restore lost imei is either contact cvxcvx directly, or Samsung. Samsung will charge a lot more than cvxcvx.
