Hello everyone,
I've been searching the web high and low about an issue I'm having. This past Saturday I lost signal and I cannot understand why. It was working fine that morning as I had received a call at 10:30. About an hour later, I checked to see if I had any msg's, etc, and I noticed I had no signal. I checked my IMEI and it's /00 and that is it. 1. I'm wondering how can a phone simply just lose its IMEI in such a way. It wasn't dropped or anything. Actially it was laying on my bed when this occured. I've had marshmellow on it for close to a month with zero issues. 2. Is it possible to resolve this?? Every method I have found I have tried and yet, the IMEI, or lack there of is still stating /00. I've reverted it back to stock to no avail, and just this morning RErooted it and still nothing. It does show bars and if I move from place to place, it will go to like 3 bars, or 2 bars or back to all bars as though the phone knows the sim card is there, but no data connection nor can I make calls. I also got a new sim card thinking my old card went bad, but I'm getting the same issue. Any and all suggestions would be greatly appreciated. Thanks all!
I apologize ahead of time in case there is a thread already that relates to this issue, and if there is I haven't found it yet.

Hello all,
my Defy is stuck in emergency mode and can't find my carrier anymore (o2). Details:
- only emergency calls possible, no network found
- another mobile in my house gets outstanding connection (o2 aswell), when switching SIMs, it's still my Defy not getting a connection
- wiping the Defy has not changed anything, even with stock settings all I see is the red cross (put my settings back with clockwork recovery)
- an hour or two before this happened I was listening to music with my headphones, but between taking the headphones out and GSM failing I was sending texts
- When doing a search for other carriers I can see some (though not reliably), but not mine
- I bought my Defy via Amazon, so no SIMlock, obviously.
- WiFi, Bluetooth and GPS are all working fine, so they probably have different antennae
- I rooted my Defy, but this was over a month ago, and it was working fine. I also did not install apps or update some existing ones before this happened. I also did not reboot. It just happened. Put it in my pocket and next time I got it out there was the red cross.
In Phone Info -> Status it says under signal strength "-111 dBm 1APU". It all looks like the antenna is broken, but I didn't hit it, drop it, put it into water or hurt it in any way before this happened or the 3-4 days before. So I'm really lost here.
Anyone? Thanks in advance.
Hi. Have the defy for about a month now. Same issue since first day. Dont know whats wrong. Found out that after 4-5 reboots its ok and lasts till next reboot/switch off. So try turn it on/off 4-5 time or just download a quick reboot app and do the same to see what happens. If aneyone has any idea on how to fix this?
i get this all the time when i flash my defy thru any other rom......and thus roll back every time to stock (indian) rom.....
try flashing your phone with any compatible rom....new radios might get ure phone working
Same problem here. First time today, spontaneous, after a month of use my Defy, non rooted, never unlocked, standard noMOTOBLUR, just like as it was bought from store. Moto_Versiuo.2.34.1.MB525.Retail.en.SEA
None of these worked to restablish the radio connection: succesive reboot, manual/automatic network search and choose, succesive airplane on/off. I didn't check the signal parameters.
I thought that the SIM just burned, removed and try it on another phone and everything was OK. When put it back in Defy, the network connection was established.
The experience was very strange and my final verdict was that the SIM just moved a little from its initial position.
BUT now I realize the problem is more complex and I don't know what caused it !
I have also noticed that the sim card slot gives a little more space for the simcard to move (at least on my defy). Might be a prob with the sim card being old or something (mine is from 2005). For now i'll just try to keep my phone on (seems i finally found stable settings for setvsel, so no more unexpected reboots).
An answer from motorola's official support forum is just remove the simcard and clean it with some cloth...
This is definitely a sim slot/card problem. If bought from amazon they will oblige to change it without any money. I did the same but not for this problem.
If you think there is some problem with software, which is unlikely then flash an sbf and see if things are fine.
To begin with flash chinese froyo sbf. It is downgradable to any previous firmware you were using and very flexible.
Hope this can solve your problem. Get back on what the result is.
Same here...
My defy got network yesterday at 07pm til mid-night.
before, since 16 (11pm) til 19 (7pm) before it function again.
and now, its bloked.
i rooted my cell one month ago, then, probably thats not the fault of z4root.
Sorry about my badass english, i still in upgrade mode.
any idea about it guys ?
thnx

Problem solved replacing sim card with a new.
ISSUE RESOLVED
Hi guys, I don't actually own this phone but I'm asking this on behalf of a friend. I've searched everywhere, including google, and have not found an answer.
Recently my friend's phone underwent a weird change. According to him, he was in class one day and had absolutely no service because it was in a basement. When he left the class though, his phone stopped displaying the Verizon name, in both the status bar and everywhere you would normally see it. Instead, it now seems to say that his service provider is Vodafone NL, which according to my research is a Netherlands based phone provider.
We live in NYC though so that's a bit of a problem. He is able to make phone calls sometimes, but he is apparently unable to send or receive texts, and cannot access any data.
He's waiting a day or two to see if it fixes itself, but he intends to take it to Verizon to have them check it out eventually if there's nothing. Anyone have any idea what the problem might be?
His phone is completely stock btw, no mods or root or anything.
UPDATE: Nevermind, I managed to resolve it for him by having him switch to CDMA and then having him scan networks for Verizon again. That seemed to fix it. Still no idea what caused it to switch to Vodafone though...
So I wanted to see if somebody would provide me with the settings they have for the SMSC. Starting this morning I was no longer able to send text messages and I know its not an issue with a ROM or anything because I Odin'd back to factory and I am still having the issue. This isn't the first time I have had an issue with a GNex not being able to text and I had to take my old one back to the store and get a replacement because they were unable to fix. I think I stumbled upon my problem/solution and was hoping that somebody from this great community would help me out. Could somebody do the below and paste what settings they have or give a screenshot. THANKS in advanced.
Open Dialer
Type the following sequence *#*#4636#*#*
Open Phone Information
Well for starters, My first Gnex had this issue a few days after receiving it, approximately one month ago. This morning I noticed I was once again unable to send or receive text messages. Up till now, I have been stock with root. I have been scouring pages and forums trying to find more info on this problem.
Unfortunately the farthest I have gotten is a wiki page on Cyanogenmod that goes through the process of updating your SMSC based on your Carrier's Gateway Number and putting it into PDU format. You can fidn the gage here.
To make it worse, as I thought I was going to be able to manually update it and get SMS back up, i still receive update error.
To make matters worse, for the past four days calls drop out every four to six minutes regardless of coverage. Not just on my line, but my wife's and my sister's lines as well. However they have not been able to reproduce any SMS problem like the one I have once again come across. I'm pretty close to dropping Sprint even if I've got a year left on contract.
Thanks for the reply. When I went to update or refresh the smsc I would get an error as well. This is my second GNex and really frustrated by it. I ended up odin'ing back to factory to and called sprint. they had me re-activate the phone *#*#72786#*#* then a few minutes later it started working again...
Well at least you were able to get yours working again. I've performed several resets via the 72786 menu to no avail. I went to a store today, to see them try it themselves, and eventually reactivate it. After seeing my problem was the same as the last, They decided to order a new/refurb phone. If this doesn't work out I plan on going back to my Evo 4G or just dropping my line on Sprint.
Well last night the modem died completely, this is some bull****. Can't connect to any sprint towers, makes me wish I still had my old phone. With 3 lines I just cant spend that much money to leave sprint.

I completely understand the cost of leaving sprint. I'm in the same boat with three lines as well. I have read up that in many cases an etf can be waived by returning the phone.
I am currently waiting for a new nexus to get shipped out here. If this third one doesn't hold up I'm going to have some bickering to do with account services. The other two lines are only experiencing dropped calls every few minutes and after talking with several reps, there is ongoing maintenance in my area.
What I want to know is why can't the smsc number be updated. And then why after wiping system and data and then flashing stock, that the smsc still cannot be updated. Something about the smsc cant be updated or there's a read error, corrupted sector, i dunno. I feel like I have exhausted everything I can think and tried everything I can. Not to mention this problem seems relatively isolated.

Device: European GSM model "YAKJU"
ROM: stock 4.2.1, freshly installed from Google provided image
I swiped my device a few weeks back, after a bad experiment. Reflashed the Google image and all was swell. Until a few days back, my phones radio seems to crash at arbitrary moments, yet very often.
Symptoms: good reception, able to use internet over EDGE/3G and all of a sudden no coverage whatsoever. Nothing then works: tried going into airplane mode and back, tried resetting the radio in the telephone info menu (*#*#4636#*#*), the only solution is to reboot the phone. Then we're back to square one: everything works for a short while (minutes at best) then zilch again. Very frustrating!
The funny thing is, the telephone info menu still gives me info about signal strength. Also, IMEI number is no problem, I still have one (seeing this seems to be a common issue).
I'm completely lost here. Why would my phone, all of a sudden, be doing this? Anyone? :-\ Is there a logfile somewhere I could look at (rooted phone), possibly telling me what's crashing exactly?
UPDATE: well, I thought swapping sims with a colleague would be a good idea to troubleshoot further (and make sure it wasn't a faulty sim card), but to my horror I now get no service whatsoever, even after a reboot! The phone doesn't even ask for a sim code... Yikes? Hardware failure or still possibly software? Would a factory reset do anything?
UPDATE2: Factory reset didn't help, at all. Same issue, no connection whatsoever.
UPDATE3: What the ****ing ****. I reflashed the stock Google image (again) and at first it seemed much worse: I no longer had a IMEI (*#06#). Hit the Google and saw nothing more than "ahh, sucks, send it for repair!". So I was preparing to do so, took out the battery to write down the serial, popped it back in, rebooted and... all is well now. IMEI is back and it seems to have and keep its connection now?! I don't have a single clue on as what and/or how though, but it sure as hell is no hardware issue. Google, get that **** together, this was your flagship phone! :\
UPDATE4: Spoke too soon. Scratch the previous update, I just lost all radio again. Back to square one!
Noone?
Something really weird is going on with my At&t galaxy s3. I'm new to this forum so I'll just explain what I'm experiencing and do my best to work through it will all of you. This phone got rooted by someone else and when I got it, the rooted program was in chinese and was acting all weird and wasn't getting good reception, although it was before it was rooted. I flashed it back to normal and it's acting very curious. It will receive an At&t simcard but the service bars will go from 1 bar to 4g to Edge to 1 bar all in a matter of 20 seconds or so and doesn't seem to work. It will occasionally work to send messages, make calls, but it seems like it can't ever receive calls. I checked and the IMEI number is still the same. Also, I had originally tried to unlock it to another carrier and when I put in different simcards (From other carriers such as verizon) the service bars don't show up, instead, all it shows is a cancel sign and doesn't ask for an activation code or anything. I'm honestly not sure what to do here, I thought I had broken the simcard reader and replaced that, but that made no difference. I'd greatly appreciate any help. Thanks!

Unlock is supposed to be permanent so it's odd that you lost it.
Now as for your problem, a lot of people are getting this issue lately, where unlocking damages their nv file. The solution can be found here: http://forum.xda-developers.com/showpost.php?p=43842387

Thanks for your quick response I have been looking for a long time and never saw this issue before. I'm not sure where I'll be able to find a replacement nv file...but i'll see if anyone I know has a galaxy s3 from at&t. Maybe once I do this the unlock issue won't be messed up anymore.
