Alright, here's my issue. I got the phone unlocked about three months ago, worked perfectly. I get great signal with AT&T, always have. I don't have a data plan or anything, phone gets wifi fine.
One day I stopped getting cell service. It appeared on the phone as the circle with the line through it. I thought it was odd since I always get good signal. Still got wifi fine. Took the SIM out and put it in my nokia, full bars. Tried playing around with the APN settings, nothing. Reformatted the phone, nothing.
Went and talked with an AT&T guy and he gave me a new SIM card. He put it in my phone, unactivated, and it worked great, showed up with full service. Once he activated the SIM, it went back to saying no service. It doesn't say no SIM, just that I don't have any signal at all.
When I take the SIM out and power on the phone, I get the no SIM error and it shows that I have full signal. Once I put it in, nothing.
Right now I am just using it as a wifi device. I am not really sure what I should do, and I can't return the phone.
Any help would be greatly appreciated.
my wife's Glide is getting the same problem behavior as outlined in this thread. With a new phone, new SIM and new battery we see the no network icon and Service State=unknown in phone status. No sim card error anymore, just no network. I'm going to take the phone in to the warranty center for another new battery and SIM card. I'm not optimistic. Add to that ever since we got the Glide, the phone would not ring or show missed calls sometimes when people really did call.
The AT&T warranty center offered my wife a different phone (new) as a replacement, but the Glide is the only decent Android phone with a keyboard and she has to have a keyboard.
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....

I did not do any kind of flashing or radio changes prior to Tuesday, when I lost signal.

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 bought my note 4 on launch day. Ever since then I've had an "unable to detect sim card please restart phone" error. At first it only showed up once every few days, but now it is getting more and more frequent and is happening multiple times a day. After reading starting the phone works fine for a while. I've done everything I can think of (pulling the battery, pulling and re inserting the sim, cleaning the sim), but nothing helps. Anyone else having this issue, or know of a solution? Thank you.

I am having the same issue. Not sure of a fix yet but it is getting more and more frequent which worries me.
Same here. :sadface:
Same here! Anybody contact Samsung or Sprint about it?
Same here!!!
Just got my note 4 from Amazon.com. I had been reading about the lte to 3g call drop issue, and someone posted using there sim the card from the phone they were replacing fix this issue. So I put mine in from my s4 before i even turn it on for the first time. The phone worked, but was unable to connet to the 4g (lte / spark ) network. 3g worked fine. I got the message you all are getting (no sim, restart device....). It would happen like every 10 minutes. Once I put the sim that came with the phone in , all my problems went away. Long story short, you need another sim card.
I just called sprint and they are sending me another SIM card. It happens from time to time, but they did tell me if it continues, I can get it replaced for no charge.

This happened after my sim card swap. It would say "network did not respond in time" then "could not detect sim" then phone would reboot. It did it three different times. Then connection became stable and has not done it again. Not sure if these issues are the same as whats happening here. Just posting my experiences.
I actually bought 2 N910P. I planned on making a little extra money by selling 1 of them, but didn't count on the N910P being so easy to get, so I've held onto the other one for a back up until I found a ROM that I wanted to run on it. Well, I found a awesome ROM & booted up my 2nd N910P & got the message you have all mentioned. I thought it was strange, so I rebooted & got the same message again. After doing this a few times, I thought why not take my SIM card from the 1st N910P & put it in the 2nd N910P. I still got the same message after doing this, so I swapped them back before it messed up my primary SIM card. @Yoshi1221, please keep me/us updated if the new SIM card works for you. Has anybody else got a new SIM card? Also, after installing the 2nd ROM that I was trying out, the fingerprint scanner stopped working. I went back to stock & it still doesn't work, so I made sure that I did a full NANDROID backup on my 2nd N910P in hopes that once I get it working & the fingerprint scanner stops working, I can go back. Anyone else had this trouble?
Edit: I tried to activate my new GN4, but the DEC & HEX numbers were not recoginzed by Sprint.com. So I went into chat & they informed me that it had been turned over to technical support & to contact them again after 24 hours, so we'll see where it goes from there.
Update: Chatted with Sprint & the lady activated the SIM card after giving her the number. Hope this will help out. Just go to Sprint.com & click on the chat button.
Looks like new SIM card is working, but just got it today, seriously had to give up an arm and leg in order for sprint to send me one, but so far it looks like it is working, but just got it today, lol

Cool, glad it work out for you.
Also found out from a supervisor in the U.S that sprint is now selling GSM phones now. If you take out the SIM card and only receive 3G, you have a GSM phone, if you take out the SIM card and have spark/LTE, you have a CDMA phone

I had this problem. Sprint sent me a new sim. Fixed the problem for a few weeks but it has returned. Anyone ever get this figured out?
Sim card not found
I had forgetten about this error. Saw that someone suggested a piece of paper between the sim and case cover. I had this happen with a phone I got off a forum. Sent it back and got a replacement. The paper, no matter how thin or thick may or maynot work, and only for a short time. Changing the sim might not work either. You may just need a new phone. I went through all with a s4. Now my note 4 is doing it. I thought it was my recently deceased (July 4) mother was messing with me. One more errand to add to my list for today.
same here?
help plz
Hey all - long story short, my upload speeds today topped out at .13MB/s, so in desperation I called Verizon, who did some resetting on their end and talked me into resetting my wifi/mobile/bluetooth, which is in settings/system/reset options.
Since then, I've had no 4G and nothing has brought it back. Just did a factory reset and STILL nothing!!
Interestingly, when I open up my APNs, there's only the Verizon one, but it's never selected - even if I select it, still no LTE, and after a reboot it's unselected again. Also with this phone seems I can't edit or add APNs.
I am *absolutely* out of options - really figured the factory reset would take care of it!! I would be most grateful for any help you can give! Thanks in advance - can't tell you how much I appreciate it.
So fun story - on a whim I put the SIM of another 4G phone in, and works like a CHARM. So somehow resetting the wifi/mobile/bluetooth fried the SIM! I think I got one for free at the Verizon store last time this happened, so I'll head there first thing tomorrow!

So you put the SIM in another phone and it worked fine? I am pretty sure you just proved the SIM is fine and the problem is in the device, or it's configuration...
I have been through a dozen phone on one SIM, never had a SIM fail and I have only replaced it when changing carriers. Odd that this happened to you, and happened at least once before...
Nope, I put another phone's SIM into my phone

But you put your original SIM into another phone and it worked fine in another device? Or am I misunderstanding?
I am not trying to argue here, just understand...
No, I never did - I didn't try my SIM in another phones, but I did take the SIM out of my girlfriend's phone and put it into mine, which then immediately got a 4G signal, so I knew the SIM was the issue. Ran to the Verizon store for a new one, and the guy there said "whoa, that's a really old SIM" and I had to remind him what a SIM cutter was - I've had it a while
