I have the same issue, calls drop during calls, cellular signal is not stable. Sometimes it says "not registered in network" as yours do. Have you found any solution yet?

[Q] Emergency Call Only Brazil

Hi all,
I bought a Unlock Milestone 2 in Brazil and have a big problem.
It only works with a Oi mobile operator network, the others Claro, TIM and VIVO signal does not appear, but the internet works.
My M2 has the custom retail firmware from Brazil and I've done hard reset, reinstall the firmware and it still in emergency call.
I read something about what may be the baseband, but how can I get and install?
My phone is rooted with z4root.
Best regards.

im not sure if changing the baseband might help, but do check out this thread. perhaps somebody has an answer to ur question here.

I dont have this problem
Try APN Brasil app, you can find it on Android Market. You just need to open and tap "Configurar APNs" (Configure APNs).
I bought my Milestone2 from TIM and used on Oi for some time, now im using in TIM without any problems using APN Brasil.
I only used APN BRASIL.
Have you tried to reflash your device with Brazilian Stock ROM?Try to change to WCDMA preferred or WCDMA only. To do this, open dialpad and press:
*#*#4636#*#*
If you reflash, dont forgot to reinstall APN Brasil.
Hope it works, buddy!
Remains the same.
The cellphone get signal after minutes, stay 10 minutes with signal, i used.. but suddenly appears the "emergency call only" message

I tried to reflash too, and then used APN Brasil but nothing happens

Do you change the baseband to 2G ?
Similar Problem
I have an lg vs980 and I was using it with H2O wireless and later I changed to Simple Mobile. I'm living in Puerto Rico. The phone was working all right and, suddenly, one day it was always displaying 'emergency calls only'.
I did factory reset, then I reflashed stock lollipop and it was like nothing happened, keeps displaying 'emergency calls only'.
Then I found this post http://forum.xda-developers.com/show....php?t=2394689 and applied the patch but didn't seem to resolve the problem.
As a last resort I tried flashing cm 12.1 and before first boot applied the patch from the cited thread but no result, keeps displaying 'emergency calls only'.
Has anyone found a solution to this problem?

[Q] Phone crashes - not network detected

Dear Colleagues,
First of all, my apologies if this issue was included in some other post, but I was not able to find it.
I have used the following tip to root my Atrix:
http://forum.xda-developers.com/showthread.php?t=1255548
Everything went ok until yesterday. I left my phone charging during the night and when I woke up, the phone displayed a message saying that "SIM Card is invalid". I've rebooted the phone and everything went back to normal. 20 mins later, the same error showed up. Rebooted again, and it worked again. A few minutes later, I've tried doing some calls and the dialer looked like calling but it was not able to connect. I have restarted again, and the same happened, only that this time no data was being transferred. I checked the APN and there was none. So it seems that it was deleted by the phone. I re-entered the APN info, everything worked again, but this morning the same happened after charging. Now my phone displays randomly the following error message: "The process com.android.phone has stopped unexpectedly. Please try again.", the APN is gone and it restarts randomly. Any clue?
Should I do a factory reset?
System Info:
Android: 2.3.4
Build Number: 4.5.91
Carrier: Movistar Argentina
Any help is greatly appreciated.
Thank you in advance.
Regards,
Fernando

thanks
edit:
i bought the phone "new" from ebay. everything seemed and appeared new and clean on phone so i am inclined to believe that it is in fact new. i have unlocked the bootloader, rooted the phone, and entered a code to carrier unlock it. the code appears to work as i have recieved the "phone is now carrier unlocked" message. however, where my bars should be i have an X. then, when i search for a network i recieve 3 networks: 2 att's and one tmobile. I am using a Claro (dominican republic) sim card. i try all three of the searched netowrks and recieve the same error for all of them: "network with limited service found." now i have an exclamation mark in my notification area which reads: selected network (att) is unavailable.
please help!!! i leave for the DR on sunday and need this phone to work!! thanks for your help in advance!

[Q][HELP]Network or Sim card error/Samsung Kies unable to connect

Hey guys i need some help. I'm having a problem with my SGY. I cannot receive calls and text messages but I can send. When I go to Call settings>Call forwarding, it says "NETWORK OR SIM CARD ERROR". But when I restart my phone, I received the messages I wasn't able to receive. This always work when I restart my Phone. But, I cannot restart my phone 5 times a day so I searched google and then I found an answer which is upgrading the firmware/software using Samsung Kies. But the problem is Samsung Kies can't detect my SGY. It just says "Connecting.." but it won't connect even after 30 mins! How can I fix my SGY so I won't get the "Network or Sim Card Error" and receive calls and messages like before?

If none of the above tips work.. then flash a sweetable package for your region via odin... u can find odin flashable bundles in the general section.... And then try to reconnect with kies.... Hope it will work....

[Q] stock 4.4.2. No service, data works fine

Dear all,
You are my last resort. I've been trying to find out how to fix the problem, but no success...
My Note3, 9005 (bought new, without contract), has never been rooted or modified in any way. Current version is 4.4.2. IMEI is fine. Well, I am a regular user, who keeps updating the phone, when there's an update from samsung OTA.
I've been using the phone for 1.5 year, everything was fine. I recently switched the operators (Belgium) maintaining the same phone number. And there the problems started.
Very often I get "no service" message, although data connection works fine. I tried automatic and manual selection of the network, but the problem remains. When I select automatic network, I get the message "registerred on network", but "no service" sign remains and get no call connection (data connection works fine). When I select the network manually, I get a brief message "registerred on network", but still no service and then "the network is unavailable"/
I contacted the operator, they claim that my account is fine, they see no problems on their systems. The interesting thing is, that other operators SIMs work fine with my Note. Apparently, it is only my current SIM which fails to work. I have two different phone numbers SIMs from this operator and they both have a frequent "no service" in my Note. I have also requested a new SIM, which again did not work... The same SIM works fine in Sony Xperia. I have also tried that same SIM in galaxy s3 (LTE). And there was again a problem with connection, i.e. no service, but data functions fine. I have also tried different modes (3G, 4G), the problems remain. It looks like it is the problem with samsung devices.
This is the time when I really need the phone for my work...I keep failing my clients because they cannot get hold of me. And changing the phone number and operator would be very inconvenient at this time.
Is there anything I could do to fix it?

try to flash stock firmware of your country via odin. i hope its work.
Nico, many thanks!
I understand my phone was brought from the UK. But currently I am in Belgium. Could you please tell me, what country firmware should I use, what specific firmware I have to flash? (I would appreciate if someone could refer me to a download link...I am not very good with these types of things, I am afraid to mess things even further...)
rooted, reinstalled stock 4.4.2. Now when making a call, the network dissapears and connection dissapears and becomes "no service", therefore the problem remains. data connection works fine.
guys, please advice, what can i do to fix it? should i go for other ROMs (not stock), would that help?
i've read about ariza patch, but did not understand whether it is available for note 3 4.4.2.

1. Install Kies 3 and conect your phone to the pc.
2. Take a look your CSC (pic attached)
3. Go to Sammobile.com and download the correct firmware (with correct CSC) for your device.
4. Flash this firmware through ODIN.
5. Enjoy :highfive:

Joku, thank you very much for your reply!
But I think I did exactly what you have recommended in the first attempt - flashed the stock version. Please see the pics of kies and suggested sammobile firmware attached. ...But "no service" problem remains. Althoug, I must say, it goes away from time to time (better than it was without reinstall). Maybe I should go for other country firmware (for example Belgium, where I am currently based and where the problems persist)???
After reinstall my firmware is:

All seems ok. Make a thing:
1. Backup your data and factory reset your phone (Pic attached)
2. Tell me if you have service then.
This is obviously a carrier issue as you stated yourself other carriers work fine. You can waste your time throwing things at the problem, but I'm highly confident it's not going to be fixed by anything you do.

It does sound like a provider problem...
Try a factory reset first, just to be sure. Best do it through recovery, so you can wipe the cache as well.
Does the no service happen everywhere? Or just in specific places?

Thank you all for your replies.
The problem is that the same 'no service' SIM works fine in another phone (sony xperia), the provider will claim that it is note3 fault.
I did factory reset after I reinstalled the stock version.
It looks like ' no service' appears when the phone changes the cell/network towers when travelling from one location to another. .. But I can't say that it is always the case. I just don't find any logical reason to fully explain that.
The weirdest thing is that data connection works fine always.

It is probably related to the way your provider does the 2G/3G/4G band allocation and switching - what provider is that?
You can also try to set the data to "3G only" vs "LTE/3G/auto" and see if is any difference.
The provider is Base (via virtual network provider).
I've tried everything, including changing to 4g, 3g, etc. Nothing helped : (
Should I try flashing different modems? The question is, which versions should I go for. ..?
updated to lollipop. no changes
I still haven't solved this issue. I just updated to lollipop (via CrashRom), the problem with "no service" remains.
Is there anyone with similar problems, who was able to find an answer? What else could I try? Should I try flashing different modems? Could anyone help me choosing which modems should I try?
pleeeease.... : )
anyone please?
can I try flashing different (older) modems? would that mess up my curent rom?

Check this post for downgrading from Lollipop to KitKat.
Regarding to "No service" problem, go to the ServiceMode MAIN MENU and try NV REBUILD.
To open the ServiceMode MAIN MENU:
- If you have root, install Phone INFO ★Samsung★ app > Menu > 'Secret Codes' > *#27663368378# > 'Launch 0'.
- If you don't have root, open the dialer > *#0011# > Menu - Back > Menu - Key Input > Q0 > wait... until it appears
iritoi said:
firstly, many thanks for your advice to rebuild nv.
i did as you explained, but... it did not help.
i went through all of the options available, flashed stock firmware, flashed various roms. nothing helps. what's interesting that i have call availability (service) for some time, but when i move to different area, the service dissapears and i have to turn on/off airplane mode. and this happens with specifically one provider (mobile vikings/base - belgium). if i insert the other provider sim, note 3 works fine.
my imei is ok.
pleeease help me to fix this problem. what else can i do? is theo nly option left to change provider?

Your best bet is flashing back to original stock firmware.
And try to check your SIM card in your Note 3 by follow these steps:
In the ServiceMode MAIN MENU, select DEBUG SCREEN > SIM INFORMATION, you will see 3 options. Select every option, capture screenshots and post it here more more checking.

In the band frequency it says "unexpected value". Maybe that has something to do with the problem... Or am I being listened by secret services : )

Mine are the same.
Except for the 1st screen: SIM Phase = 2; SIM voltage class = 3V.
The 2nd and 3rd screens are the sme.
is there a way to see the reason why the network is being disconnected via service menu?
...because when i turn airplane on/off, the network comes back. but when i dial the number it disappears right away with the message "network not available".

Yes there is. Here is how:
- If you have root, install Phone INFO ★Samsung★ app > Menu > 'Secret Codes' > *#197328640# > 'Launch 0' > BASIC INFORMATION (capture screenshot #1) > Menu - Back > NAS INFORMATION > MM INFORMATION (capture screenshot #2) > Menu - Back > MM REJECT CAUSE (capture screenshot #3).

[Q] [I9500] Not registered on network after changing rom - Please help me

Hi xda team,
Sorry for my bad english. I have a serious problem on my SGS4 I9500 and I checked on this forum and web searching for solution but nothing :crying: .
I bought a SGS4 (I9500) 2 week ago. The phone was working without problem on KitKat 4.4.2 (sorry but I don't remember which version of KikKat) until i decide to change rom and to update to lollipop 5.0.1 (I9500XXUHOA7). After flashing my rom I can't make calls/sms and can't access to internet through 3G because my phone doesn't recognize my sim card. There is a message saying "Not registered on network" and IMEI was generic (starting by OOXXXX...).
So I checked on XDA and internet to find out the way to resolve this issue and I tried many things:
Change modem : I tried to change my modem to MODEM_XXUGNL1. IMEI back to normal (starting by 35xxxxxx...) but I still can't make calls/sms and connect 3G
Downgrade FW : I downgrade FW to KitKat I9500XXUFNB3 but IMEI was null/null. I change modem with Modem GNJ6 (Modem.bin). IMEI back to normal but I still can't make calls/sms and connect 3G because when I tried to call/sms I receive the same notification saying that "Not registered on network"
Register network manually : I tried to register network manually. My I9500 tell me that sim card is registered but when I try to call I see "Not registered on network"
Wipe data/cache : I wiped data/cache using Samsung recovery and philz_touch_6.12.8-i9500 but nothing :crying:
Note that my sim card is working fine on other smartphone and other sim cards not working on mine. Always the same message "Not registered on network" :crying: . And when I tried to call a sim card in my I9500, I hear ringing tone during call attempt but there is nothing on SGS4.
I'm disapointed and don't know What I have to do to repair this issue. I know that you are wonderful :good: and I hope that you will help me to find a solution for my S4.
