Okay, so I got my Galaxy Nexus today... went to put my SIM card in, and it refuses to acknowledge it. I thought maybe it was due to a very old SIM card, so I went in to T-Mobile, explained my situation, and they replaced it with a new SIM card free of charge. Problem is... the Nexus still REFUSES to read it. It keeps saying 'No SIM/Emergency Calls Only'. Help please?
Is the phone new or used? And do you have warranty? It could be because of the phone
It's used. It came pre-rooted with AOKP on it... I was thinking this might be the problem? So, I'm in the middle DLing the GNexRootToolkit to return it to complete stock, and see if that helps. Any other thoughts?
are all the pins there? If any of the pins in the SIM slot are bent or broken, it won't read the SIM.
I also find it hilarious that people buy used phones without knowing for sure the SIM slot works (one reason to only buy locally for used devices). I personally will never buy a used phone that is also rooted/unlocked/ROM'd. I don't wanna get some hand-down phone that's been messed with. If they can't be bothered to return it to stock, I won't buy it.
Okay, that seemed to fix it. Thank you for the quick replies!
Can't believe you bought a phone without checking if it worked. Smh. Well, glad it worked out for you.

what was your fix? i'm having a similar issue here: http://forum.xda-developers.com/showthread.php?t=1707311
Hello,
A bit about my Nexus: Bought it online, it's the Domoco version, unlocked, rooted and been using just fine with many custom ROMs.
So yesterday morning, I was talking on the phone with a friend without any problem. After hanging up for a few hours, when I was about to call someone else, I realized my phone didn't have any signal at all. And it has been like that until now, about 48 hours.
It happened so suddenly without any warning. The phone has never been dropped and everything else working just fine.
So here's what I have tried:
- Restart the phone (multiple times)
- Batter pull (multiple times)
- Factory reset the phone (multiple times)
- Wipe cache and dalvik cache in CWM (multiple times)
- Downloaded SetCPU and set the minimum to 700Mhz (instead of 350Mhz)
- Reflash the ROM and tried with other Custom ROMs (I tried Xenon, Xylon, PA, and Carbon ROMs)
- Reflash the Radio and tried with other Radios too (I tried UILH1, XXLH1, SC04DOMLE3 and some others ...)
- I also went to Tmobile and request a new sim card - same problem.
- I borrowed a sim card from another Tmobile customer to try it on my phone - no signal - but the sim card works just fine on his phone.
I ran out of thing to try and I dont understand what happened ... anyone has an idea or something else for me to try ?
Anyone experience this before ?
Welcome too my hell. I have a playstore one now but my first Gnex was an international one and it has this same issue. Its a PCB problem a warranty would fix. I'm near Chicago and a few people have told me there is an electrical engineer downtown that fixes stuff like this. I don't have a price but I think something like this is your only option. Mine sadly is still a battery charger:thumbdown:

I know it sounds stupid, but have you tried toggling airplane mode? I run into the occasional loss of signal when im at work [fair to weak signal in the big metal box], and a reboot is the only thing that fixes it for me. Mines a play store model.

Ah yes, I actually did try that too but forgot to mention. I tried toggle airplane mode on and off, also the 2G only mode on and off. But it didn't help with anything.
Thanks for the suggestion.

So I guess I have to look for an electrician then, cause I have this phone just a little bit over a year so warranty is a no go for me.
Thanks for the idea.
PS: anyone else has more option for me ? I just wondered if I have bricked my phone ... cause I flashed lots of diff. ROMs to try out but never gotten a bricked phone before, could this be a bricked phone ?
Bricked refers to a phone that does what a brick does: nothing. It doesn't boot, it does not light or attempt to boot, it does nothing. This is a signal issue..I have no prior experience with docomo, but this thread came up on search: http://forum.xda-developers.com/showthread.php?t=1574018, maybe it'd be helpful. Have you converted it to yakju or takju and tried a google factory image?
And this: http://forum.xda-developers.com/showthread.php?t=1554150. If it is a circuit board, it kinda looks like s.o.l., and im sad to say that to you.
I wanted to let you know that I experienced the same issue. I bought the unlocked Docomo Galaxy Nexus, and had it working fine on T-Mobile for half a year, and then suddenly had no signal on Tuesday. Nothing I did - factory reset, battery in and out, sim card in and out - could fix it. Have you tried using different sim cards in your phone to see what works and what doesn't?
I figured out that my phone will accept AT&T, and actually does connect to T-Mobile while roaming (I used an international sim card). But, my phone will say "Cannot find mobile network" when any T-Mobile sim card is inserted.

I also have the same problem with the docomo phone. ATT Sim card works. Tried other's T-mobile sim cards and it doesn't work. I wonder if somehow the IMEI has been blocked by T-mobile.

I know others who bought their GNEX through the Play Store and those work just fine with T-mobile. I tried their sim cards in my phone and it doesn't work. I don't think T-mobile is intentionally blocking the docomo phones, because I'm getting T-mobile through roaming, when I use an international sim. My guess is they're doing something to the cell network that just somehow leaves our configuration out. Hopefully it's temporary, but who knows.
Worse case, I'll just purchase a Nexus 4, because I love 4G data for just $30/month with T-mobile. Anyone else got suggestions?

Alright, update on this and there' good news. I called Tmobile and they said my IMEI is actually Blocked. The reason, according to him, is that Tmobile usually sweep the network to clean up all "un-supported" devices, so my device is apparently one of them and therefore got blocked about 2 days ago.
So he said for this, he needs to escalate it to business support and they surely can unblock it for me, but I have to wait until Monday since they don't work on weekend. But well, that's surely a good news. phewwwwwwwwwwwwww !!!
So to all of you guys who are in the same situation, make sure you call Tmobile first before flashing crazy like I did LOL.
Thanks for all the help.
I'd love to know if you are able to get this unblocked and working as I have the same problem as of Tuesday. I was traveling and went into a TMO store, and they told me it was NOT IMEI blocked. In fact they looked at the IMEI and read the page and said 'it was not eligible for blocking'.
I called TMO to see if my phone is IMEI blocked, and through three levels of support the universal answer was no. I'm now fully confused because if it's a hardware issue, why did several people all have the same problem all on Tuesday. For those others who are having issues, can you see the TMO network but not connect to it? That's what I have, I can see TMO and AT&T but haven't been able to connect to either one since Tuesday.

I'll call up T-Mobile tomorrow and ask if they IMEI blocked my device. I had them reset my signal and give me a new SIM card, but didn't realize it could have been IMEI blocked. I'll give them a call on Monday and let you know what the result is. Maybe it won't be too late to cancel my order on that Nexus 4...
I'm quite confused. I've been told last Thursday in a TMO store and with tech support that I didn't have an IMEI block, and the same with three reps tonight. I know the Sim Card is good, and so I'm being told its a hardware issue. However, several of the same phones had the same issue on the same day, so I can't buy it's a hardware issue. Has anyone with this issue flashed a new or different radio into the phone, either before or after the service loss? I have not, running it as it came out of the box.
I just got off the phone with T-Mobile Support, and they told me the device is not blocked. The reason is that T-Mobile cannot block or unblock devices that are not registered to T-Mobile. So I'm back to square one on this.
chowabbajack - When did you first have a problem, last Tuesday? Did you prior to that do any flashing or radio changes to the phone?
We're in the same spot....

That makes me think its something to do with the radio software, because I am the same the problem overall doesn't seem as large as the number of phones I perceive were bought on the Docomo deal.
Ive been using the docomo version of the nexus as well on tmobile for almost a year and it was since last tuesday when it no longer recieved any singal. with some digging around and too many phone calls, I found that the imei number on the phone is not the same as the one under the battery. i have the generic 004999010640000 imei right now and it not sure how i got it. as i bought it unlocked.
what i have tried:
reboot, battery plug, reinsert sim, factory reset, root and flash, got a new sim card, relocked, unlocked
sim card works on other phones.
also i have called tmobile and samsung endlessly and this is what i got:
tmobile cannot unblock the imei since it is not from them.
samsung is redirecting me to their japan branch.
docomo i cannot reach.
my phone before last tuesday:
unrooted stock 4.2.1
been testing different things to see if there is any way to restore the imei
also using root explorer, i cannot find my efs folder....
I've got the same problem since last Tuesday with my GNex and T-Mobile.
Mine is not from docomo though, but the French phone provider SFR, unlocked through FDocomo apk.
Rooted phone, running 4.2.1., no changes whatsoever in the past month and it worked fine until Tuesday, so I don't think I'm responsible for having no signal.
Honestly, I am relieved to see we are quite a few to have this problem, and also very pissed at T-Mobile for causing all this. What should be the next step then? Is there any chances they fix the issue quickly? If not, I might just go to the competition. I've tried AT&T sim cards and they work fine.

I have the exact same generic IMEI number as you, which does not match the number under the battery. I'm not liking the news that you did flash and still no go. I'm a novice at this stuff so please keep us posted.
I have root, thats it, i get NO SIM in the notifications and have no data. Every now and then I would be able to restart to fix it,but now it seems its working either. ICCID is unknown in About phone. Everything else seems alright.
This is almost a brand new phone, only rooted. Had no new ROM installed on it. I restored it to the very first backup i made after rooting, same issue. I have a pending 4.3 update,which I have not updated yet.
Any idea what's going on ?
No one?

My son was having issues with his HTC One's SIM card. Data was sporadic, no LTE, and he would get no SIM card errors. We took it in to the Sprint repair center in the area and they first tried blowing out the SIM card slot but ended up putting in a new SIM card which fixed the problem.
Hopefully the person who looks at your phone is competent as we had to make a few trips as we were told at one point that we didn't even need a SIM card since we were not going Global - this older guy was wrong. We ended up having this young woman take a look at it and she swapped it out ASAP and we were good. I'm going on a bit but I was somewhat floored that their repair tech gave info that was just wrong. I've had to go back a few other times (for other reasons) and I avoid that dude at all costs (straight to the young woman).
Unfortuantely, on note 2 the sim card is not even accesible. Its buried/sealed inside, unless sprint techs have a way to access it.I am surprised this is such a low occuring issue, that no one in this forum has this.
Same thing
Same thing happened to me 2 weeks ago, i had to order a new card

The "techs" there are a joke. The only people who can REALLY help are devs who they probably keep locked away in a safe house abroad. There hasn't been a single time when a phone carrier tech was remotely helpful for me.
And the SIM is on the same module as the SD card. IIRC they can swap out this entire module. How will they replicate the same iccid onto the new one? No clue. If they replaced it and your issue was fixed though they did it somehow. Or else your authentications would be all messed up (meid> mdn>min>HDR AN>profile 0 and 1>iccid...probably more I'm forgetting)

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.

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...
Hello guys, i have some issues with my LG G3. As the title says, the phone isn't reading the sim card, sometimes, it's working just fine, for a couple of minutes, then, a countdown begins, saying "No sim card detected", in 10 seconds my phone will reboot and that's it. "No sim card detected" again.
Every other aspect is working just fine.
Things i've already tried:
- Switching sim card and switching the sim carrier.
- Replacing sim card & microSD reader.
- Pressing down the sim card at the startup.
- Hard / Factory reset.
All of those for nothing.
I'm thinking is an software problem, is that possible?
Exactly the same problem!! Has been in and had a new sim tray, worked for 3 days then back to no sim, no service, emergency calls only. Taped down sim, changed sim, factory reset, nothing!! I am so frustrated! It's only just over a year old too so I'm not due an upgrade and it's out of warranty.
I have same problem

unfortunately, this has nothing to do with our problem, my g3 shows the correct IMEI. will try to heat the area of the motherboard located behind the sim card reader with my heatgun. some guy got it to work like this ( though he did not show any actual evidence supporting his claim, and neither did i ask for it)
