Hi, I have a big problem with my device. WIthout any reason the network signal is acting really strange. I often don't have connection or i only can make emergency calls, i can still use Internet and all the apps that require a connection but i can't make or receive calls. I have to turn on and off airplane mode to let the connection normal but as soon as i end a call, the problems comes back. The strange thing is that when it says no network connection there are 3-4 bars in the signal strenght. Any idea? Sorry for the bad english

Still the same problem... 4g connection but no network connection and i can't call. I think i did everything related to the software, i change 3-4 roms, 3-4 modems and tried to change band with service mode but nothing works. It can be an hardware problem? Maybe one of the two antenna wires is detached?
UPDATE EDIT. Just now i asked for an IMEI control and it's all ok... i really don't know what it can be...
I have same problem...
I have same issue and some guy fix it via team viewer and usb redirector.
It's not hardware issue, it's about imei cert files.
Go to *#0011# and check ' Imei Status : NG' ?
If it's NG, then it have solution.

K so i got a vibrant. Its got the right product code, wrong imei(some fake 0049 thing) and when i unlocked it, it said network unlock successful. So everything shouldve been fine.
But everytime i turn it on, i just get 'no service'. It auto updates time and date and everything. and data works. But it just says no service so i cant make calls or texts.
Anyone got any ideas? I restored to factory multiple times. Odined back to stock firmware. Tried everything but no luck
This is the first thing I would try . Go to settings , wireless and network , mobile network settings then click network operators it'll search for a network and try to register to the network .

Did that a bunch of times. It just keeps saying your sim card doesnt allow a connection to this network. I tried a legit att sim card as well as a t-mobile one
Make sure you are in an area with good reception . When I lost data this is what did the fix for me . It didnt work first try either so keep searching it will eventually register the network .

I did but unfortunately no success. I have another vibrant and did the same exact thing and that works perfect everywhere. When i move over the sim card to this one, data works but just says no service.
I am having the same problem, It shows full network on the bar... but says NO SERVICE! When i try to make calls it says Not Registered on the Network... I don't get Data either... Any help would be greatly appreciated!

Yea man ive been trying everything possible. Flashed like 10 different roms. Used different techniques to mess around with the nv_data.bin files. No luck
I don't think the fake IMEI would be the issue. I had the same fake number after I flashed a new ROM from stock - I could still make calls, etc.
But if you want to restore your nv_data.bin, you can pull it from a saved stock backup, make it the only thing in efs and reboot. If you don't think you have a backup stock, try looking for a file on the sdcard called ProductCodeCheck. It may also be under SGS Tools.

You have your Data Connection enabled, right? Another think you could try is switching to EDGE to see if it works with that.
Connection on, tried 2g also...
Maybe carrier has control over tether ability?

Does your carrier allow tethering? Have you tried another SIM?
my girlfriend has a 710 and tethering works on her device, took her sim and got the same error...(i'm a qa engineer and already thought of these options so i guess is a hardware problem)

You can also try a hardreset. There were some changes in the firmwares that are only active after a hard reset.
i find it really stupid that i have to hard reset it...that;s not why i bought the phone..
what are these changes?

Well, I got some new options that allow me to configure call forwarding and the SMS charset... I doubt that it is a hardware problem. Your data connection works properly on the phone?
Yup, always has been working fine...
Is the phone sim unlocked & are you using it on a different service provider? Can you send MMS messages? I suspect WP is looking at some hard coded APN settings when activating internet sharing, & not the one entered under the cellular apn option.
Yes i can MMS messages, but i do have another problem with it that makes me think the celullar modem is faulty....i use it on 2g and sometimes when i receive a call the sound is all distorted when i answer for about 5-6 seconds and then i ca hear the person on the other end...this happens form the day i started using it...
Hi,
I get a GS3 with LFB stock, kernel stock etc.. Nothing flashed or changed on.
It's not really often, but it's like one time by week, i'm suddently on "Emergency Calls only" although i see the signal bars. I have to switch on and off the "Airplaine" mode for get back the name of my Carrier instead of "Emergency Calls Only".
Somebody can help me to find an origin ?
Thanks

First check your apn settings with your carrier, and if they are ok,, try flashing a different modern

APN settings are for the internet connectivity. They have nothing to do with making calls. Deleter all your apns. You will still be able to make calls.
hi. I came here and was about to post the same question. I am having the exact same problem as the op. every now and then the phone loses cell network connection and says emergency calls only. I simply activate flight mode then deactivate it and voila.....it's back to normal.
can be annoying when you are expecting an important call and realize your phone is not even connected to the network.
I am on a stock Rom and only rooted.

I reset miss's phone last night (ALL back to factory settings) but i booted into the phone 1st and it was great on 02 no problem, then restored it from her backup, when i rebooted and put in all the info the phone asks for i noticed it says 'emergency calls only' i been messing with the APN settings but nothing, so i decided to my sim into it (THREE Network) and it comes up fine? What could be the problem? Could it be the modem setting? would putting a diff firmware onto this help? any ibfo will be great so i can carry on with this tonight.

Read post above yours and check correct Mobile Network settings .
If wrong IMEI check with network its not blocked and restore your backed up EFS folder .
Modem has no user settings .
Possible faulty sim also .

i don't know where is the problem exactly and what can i do ???
You post a lot of information, not much of it any help.
Did the 3g ever work? Did you change something before it broke? Is the stock rom the right one for your country? Do calls and texts work? Are your APN settings right? Does the SIM work okay in another phone? Does your IMEI number in settings match the one under the battery?
Answering a few of the above many help you, also go read the stickies in general.

yea it's work every time, no i didn't change anything, yea stock rom is for my country, yea calls and texts work, my apn settings right, yea it works on other phone, yea imei match
i didn't found anything about my problem in general section !!
Do you have 3g in your location/ network ??
Suggest if you have tried correct modem and CSC for your network only other solution is a return to a service centre .
Hi all,
So my friend has a galaxy s 3 and he's not getting service so I said i'll take a look at it.
So i rooted it and changed roms and stuff and I put my sim in and add the apn settings of Giffgaff and
I got data connection H+ but then I tried to make a call and it says No mobile network phone.
I checked the imei and doesn't appear to be corrupt and I checked *#0011# and it said IMEI CERT = Pass.
So don't know what the problem is and the phone is sim unlocked .
I checked online to make sure that the phone he gave me wasn't blacklisted or anything just in case lol
Thanks!

Must be hardware failure then..If phone is not stolen/blocked different stock software doesn't work imei is intact apn settings are ok and patched modems kernels not working than all options are pointing to some sort of hardware failure.

Getting a H+ signal is different from actually getting a working data. Try to check if data is really working (browsing etc).
If there's no data even with the right APN, means the phone is probably black-listed from the carrier or you need a new (patched) modem. The right modem will solve this issue if it's not black-listed
If the data works but no phone calls, means you can try to flash stock rom and see if the problem persists.
If you were on 4.3, don't flash to 4.1.2 btw
PS: There have been a lot of refurbished/refreshed Sammy phones on the market. Their hardware issues are well known like bluetooth stops working etc etc. So if he/she got a refurb, then probably hardware issue as well.

Thanks, I can browse the internet using the mobile data connection so i can go to google and stuff but can't make calls.
I try to call the phone using my phone i get We are unable to connect to this number.
However, if it was blacklisted would I still be able to use the internet

Yes you would still be able to use the internet if it was blacklisted,I thought you had already checked to see if it was blacklisted .?

Data sometimes works even if the phone is black-listed depending on the carrier and their implementation policies. Wifi always works though.
You mentioned changing roms.
So which rom are you currently using?
More questions:
Can you try stock 4.3 for your device/carrier?
Are you using the same telcom operator (carrier)?
Is your phone carrier-locked?
