GSM not working anymore, stuck in emergency mode

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.

Data and reception problem

Hello dear friends,
My Samsung captivate glide stopped receiving 3g data (mobile network not available).
Two weeks ago I had flashed Osimood ROM, all worked correctly until now.
Now I have only the wifi connection working but the Mobile network is not available at all (I cannot even call the emeregncy numbers - it gives me the "the process com.android.phone has stopped..." ).
I tried access the Settings-wireless and network-Mobile networks and it shows me "Insert SIM card".
Then I tried *#SIMLOCK# to check if my fphone is locked, it shows me "the process com.android.phone has stopped unexpectedly".
I tried to restore the phone from other backups from other Roms , but the problem is still the same.
Please help me to solve the problem and fix my phone.

#1 Thing can you make Phone calls?
#2 Verify your APN settings for Data? Is that Fine?

Try turning off your phone and re-seating the Sim card (only do this when phone is off) Then try turning on phone and seeing if you can make calls again if it still does not work try your Sim on another phone or another Sim on your phone. If unlocked any providers should work if not try from same provider.
I once had this happen to me for some reason my Sim was not properly seated. hopefully that is all that is wrong here as well. If your Sim is not being recognized, it may be hardware. Unfortunately and some people have stated issues where there Sim was not being recognized as they removed and inserted it in the past with the phone on, which could have caused some short.

Thank you dudejb for the quick answer.
I tried to re-seating the Sim card (while phone is off),
Tried to insert another Sim of other providers,
These methods didn't resolve the issue.
I never touched the Sim card before, so I think it cannot be the hardware issue.
Any another suggestions???

You could try clearing data for Phone and Phone Data (via Settings -> Apps), but I suspect that may not be good enough. If that doesn't work, use your installed recovery to wipe data. (Note, this will delete all user data on the device and reset your ROM to first-boot state!)
If it STILL doesn't work, use Kies to restore the device back to stock (Tools -> Firmware Upgrade and Initialization). If your radio works now, there was something wrong with the ROM you had, or your baseband got corrupted somehow. You can try your ROM again if you want; if the problem coems back, try a newer version or a different ROM.
If it STILL doesn't work, you're gonna have to call Samsung support. With the device in stock state they should be willing to help.

Thank you dudejb and roothorick for time and answers.
I resolve the issue by pulling out the battery and Sim card, after blow it by compressed air (dust cleaner).
My phone is back and it works like a charm

Makes sense and thank goodness (is that even a word?) Dust blocking connection to the Sim, interesting that it can do that. Glad to see it is working again.

Also if your service suddenly dissapears try to tape the sim card in place I had to do that

[Q] no sim / emergency calls only

I've spent the last several hours trying to fix my new "No Sim" and "Emergency Calls Only" problem on my GT-N7100.
The phone worked with my SIM card last week. In the middle of a call, it stopped working. I have replaced the sim holder, rooted the phone, deleted the cache files with Titanium, and still nothing. I can remove the sim card and put it back into my HTC OneX and it works fine. I have tried my wife's sim card from her iPhone 5. It doesn't work either.
I also looked around in the network menus (8#913...). The sim shows to be unknown.
Should I look at replacing the modem software? If so, where do I get it and how do I do it?
I am an AT&T subscriber in North America.
Thanks in advance!

You just need to change your modem or reflash stock rom

Thanks for the reply. How do I ensure that I have the right modem for my location?
I just flashed it with the BTU N7100XXDMC3 N7100OXXDMC2. Still not working. Add to it, the new screen that I just installed in it last night died this morning. Now I've got to wait for the ebay store to replace it. This phone is becoming a money pit, and I can't even get it to make a call. I placed three calls on it with MY sim card before I bought it, so I know it worked.

[Q] no sim and whatsapp

Hi guys, last week, my HOX out of warranty, suddendly decided to stop reading any sim card. I've tried different methods that I've found on XDA but none of them worked (disassembly, reset, other roms, other sim). Actually it worked in 2g for a couple of hours and then it stopped every sim related connection. Now I sadly use my HOX as an ipod touch and a nokia c5 which hasn't got wifi as normal phone. It would be very useful for me if I could use whatsapp on both devices at the same time with only my phone number (c5 with sim card and HOX under WIFI). I've googled the problem and the only solution I've found wants mac adress of the phone with whatsapp and sim but my c5 hasn't got it as it has no wlan card. Any ideas about my problem? Solving the sim problem would be accepted too .

To use whatsapp you need sim in your HOX Go to some private service..^^

Update: now, if I put a sim in, everything works for about 2 minutes and then no signal again. I've reflashed radio with ril but no luck.
Need for an advice

Lenovo Vibe Shot Cellular Problem

My phone 2 days ago started to stop receiving any cellular connection from my carrier at first i thought the sim card was faulty. After getting the sim card out and put it onto another device it works perfectly fine. Some how the lock says its in airplane mode but in reality it isn't at all. Noted that i resetted the device to factory settings a few times and at first it worked but then after like 4/5 hours it went back to the problem it causing me to reset then i tried again if it would work but 2nd time isnt the charm as always.
Is there a way to fix this?I would love to use this phone more if i could resolve this issue since this isnt the time where i can spend on phone the moment.
