[Q] Can't read SIM-cards | Galaxy Nexus

Hi, I'v just got a Galaxy nexus and after a week with it sittin withiut a sim in the shelf (rewieving Xpera S) I put the SIM-card back in today. But it can't seem to read the simcard, I'v tried resetting, cleaning the simcard and have taken it out and tried again some times now.
The phone is running stock, and is not rooted, and it's a Unlocked GSM device.
Anyone who knows what I should do? Is there anything I could do?

Since you've tried a lot of methods of working with the current SIM, the only other idea which comes to mind would be to perform a factory reset on the galaxy nexus. Perhaps a setting became corrupt along the way. Wiping /data and /cache would be very similar to a factory reset and shouldn't take too long to test if that resolves the issue.
Otherwise, perhaps trying another SIM card in the device before resetting might help confirm if there is an issue with that specific SIM card and the Galaxy Nexus, or if there is an issue with all SIM cards.
Hope that helps add a few more ideas to test!

Galaxy Nexus can't read SIM card
I'm facing a similiar problem but I can't find a solution. Anyone may help me, please?
I bought my GN in France (GSM version) and it was unlocked to SFR, Orange and Bouygues but my carrier is Free Mobile. Trying unlock to the carrier I tried to unlock, root and download a ROM using Galaxy Nexus Root Toolkit 1.3 and I probably did some mistake... Every time that I start my mobile it is asked the PIN code (not the carrier code!) but when I type the correct code it always shows the message "incorrect pin code". I've put this SIM card in another Mobile and it works, so the SIM card is not blocked...
I downloaded an oficial version from google and I used Galaxy Nexus Root Toolkit 1.3 to download boot.img, recovery.img, system.img and userdata.img in order to try to "restore" the original version. The download apparently was ok, but the problem continues...
The process using the option "flash stock + Unroot" and after "OEM Lock" (in GN Root Toolkit 1.3) works but the message "incorrect pin code" continues.
Any clue to solve this? Thanks a lot for helping!

upgraded to ICS now have sim card problem

Hi All:
I've upgrade to ICS using the Samsung KIES software. Now my phone is saying my sim is not registered on my network. and I keep getting an unlock screen whenever I reboot the phone. Also in my notice bar at the top it says : "Invalid sim card. Network locked sim card inserted." This sim card worked find with gingerbread before the upgrade but now is not working,
Any ideas what I can do?
thanks,
Amsu

it relock, sometimes happen when upgrade

Try the "galaxy sim unlock" app from google market to unlock. One of the members have confirmed it working http://forum.xda-developers.com/showpost.php?p=36613342&postcount=4 . At 2 euro's i think it's the cheapest unlock available.
Not sure though the method used by the apk to unlock. If want to be safe then buy the unlock code from ebay.
BTW this post belongs to general section and not development.

Thanks for the info. I ended up buying an unlock code. Now it works. Sorry about the post in the wrong section of the forum.

How come there's no 'keygen' yet to unlock for free..?

Moved to General and out of Development

[Q] permanent unlock trouble shoot i am getting weird errors

Okay so me, my friend, and brother all have bell note 2 and unlocked no problem with the hidden menu.
My friend recently got a note 2 off craigslist but it was 4.1.2 so i downgraded it to 4.1.1 since some menu option where missing. all the menu options were there and i assumed it unlocked. So i went and flashed clean rom, and inserted his sim card and its not unlocked and saying only emergency phone calls. i reflashed it to stock 4.1.1 and attempted again and again. and searched forums for a similar problem but i havent been able to come across any. So far it seems like it works but then i put a foreign sim card in and now it says unregistered sim. but in my note 2 its fine.
I put the sim card from the company the note 2 is from (bell) and it works.
Please help it would be so great ive been trying different methods and theories of my own for almost a day hours LOL. anyhelp would be appriciated thanks in advance.

How to unlock LG-VS870 4G LTE by Verizon

Hello XDA community,
I have Verizon's LG-VS870 4G LTE smartphone [http://www.lg.com/us/cell-phones/lg-VS870-lucid2]. Now I'm in Canada and would like to use this phone instead of buying a new one, therefore I was told to unlock it. Apparently it's legal to unlock your phone now: http://lifehacker.com/you-can-now-legally-unlock-your-cellphone-heres-what-i-1614787933
So I searched online for how to unlock my LG phone. Found many results that tell me the first half of the steps. Found a couple of threads here too about it, but no concrete solution. Some people said this phone isn't going to work on GSM after you unlock it, but I found this patch thread here that says otherwise: http://forum.xda-developers.com/showthread.php?t=2394689
I have the original Verizon SIM card with me too.
Won't ya kindly help a bloke out and tell him how to get the unlock code for his LG-VS870?

So, I tried to root it and was successful with Framaroot. Then Installed Clockwork. Then attempted to install the above mentioned patch using Clockworks recovery mode, but it didn't appear to fix the GSM lock. Whenever I insert my SIM card I get an icon that looks like a SIM card with a question mark inside a red circle at the top right. And when I try to dial a number, any number, I get some chineese lady saying something.
Any idea what does that mean?
I just unbricked/unrooted my phone back to 711A firmware and 4.1.2 Android as it was all the way from the beginning.

Here's the vocaroo recording of the chinese lady(WARNING! TURN DOWN YOUR VOLUME FIRST!): vocaroo.com/i/s0C5ObqOLK6Y

[SOLVED][Q] IMEI and Baseband unknown. I don't have a backup.

[SOLVED] I put my phone in airplane mode and my IMEI/Baseband came back, cheking the service menu I went to *#2263# and saw that "LTE Preference" was enabled. I clicked on Automatic and problem fixed. Probably a ROM bug? Who knows.
Hello there. I've been a reader of the XDA forums for some time but I never had any reason to create an account to post on the forums.
A few weeks ago I got a SGH-M919 as a gift, the phone only had a few months of use and I took it with me, everything worked fine except for the fact that I couldn't get 3G/4G (Not even EDGE), I was only able to connect to the GPRS network and I couldn't change the carrier (It always gave errors like "Unable to connect. Try later" and such). Although the phone is (apparently) quadband (I don't live in the US), it just didn't work but I lived with it.
Yesterday my phone was low on battery and I turned it off, a few hours later I turned it back on and it couldn't connect to the network, I went to the network options and once I pressed the screen to enter the Mobile Network options, I got an alert saying that I must have a SIM to access those option. At first I thought that the SIM got damaged somehow (This isn't the case since it works perfectly fine in another phone) but after a few minutes looking around, I checked the IMEI and instead of the usual number, I got a null/null message. My first reaction was to google what exactly happened and the answer I received was that the Baseband (Which is also Unknown) and IMEI are stored in a folder called EFS and that it got corrupted. Sweet. I looked for solutions but the main two I got (EFS Pro and ADB nvrestore) require a backup of the EFS (Which I don't have).
The other solution I got was to restore to the stock ROM (M919UVUFNH7) which I'm currently downloading from SamMobile (Sorry if this is considered spam). The phone is not rooted and has the stock ROM, it came with a CWM folder inside the internal memory with an .img file but it doesn't have CWM intalled. I've never upgraded it (Not sure if it came with that firmware from the store if it matters).
I live pretty much in what can be considered a "3rd world country". So I cannot send it to Samsung nor I have access to dollars.
Another question is, the phone was gifted to me already unlocked, I don't know if it came unlocked from the original carrier or if it was unlocked via a code or whatever. If I restore to the stock will it lock my phone to T-Mobile again? Would I be able to use it without a SIM card if it gets locked? It's impossible for me to get a T-Mobile SIM on my hands should I ever need one. In the worst case scenario that my phone gets locked, can I get it unlocked by flashing a custom ROM?
I have so many newbie questions that are already answered in other threads, but since it's a lot of information I want to get it as specific as possible to avoid breaking my phone.
If someone can help me with this issue, I'd really appreciate it.

i having same issue in M919

Do you guys get a message in notification bar about sim car removed or something about a sim card? Also, it doesn't matter if the sim card works in another phone. This device has a little issue with being picky with sim cards. If it's a cut sim card, get an original micro sim card

Hi, thanks for answering. I don't get a message about a removed SIM card. I'm also using an original micro SIM.
I already downloaded the Stock ROM but I haven't flashed it yet.

This is a known bug of the s4. It is a hardware problem and I have yet to find a solution. If you google it you will find many threads on different forums addressing this issue. Again, no known solution

Any answer/idea about my issue? . Sometimes I can access Mobile Network Options, sometimes I can't. I can't configure the APNs (They delete themselves after I click on save). Phone Serial Number didn't get deleted (Which is stored inside the EFS folder as far as I know). I also can't select a Network Mode. I click on GSM/WCDMA/LTE but it changes automatically to nothing.

That's what I said? One solution is to change sim cards if using a cut sim card to use an original micro sim. It's worked for a friend if someone I know and also for others on XDA. It's not the solution, but works for some

I would get a new sim anyway if I could. Flashing stock firmware wouldn't hurt as well

Before trying to flash it, is there any risk of getting simlocked again? I wouldn't want to get my IMEI fixed just to realize that my phone is locked to TMB again
UPDATE 1: My IMEI and Baseband randomly got back (My IMEISV was still missing) but after I restarted, they got deleted again.
UPDATE 2: Rooted, went to EFS, didn't find nv_data.
