[Q] emergency calls only, not registered on network

hi there, i have a problem after i flashed custom ROM, the phone gets singal, but said emergency calls only, it's able to search network and i can choose network, but when i try to make call, it said not registered on network, i tried to flash different modem but still not working, any clues about it?? (it shows valid IMEI and serial number, and baseband ver: n7100dxdmf1 network: telkomsel(my current provider) service state: out of service))
I am with the same problem. I bought a Galaxy s4 i9505 from Amazon and the phone has full signal on GSM network, but when I try to make a call appears the same message always... Not registered on network.
I flashed another ROM but the problem can not be fixed. I have read everything about this problem on Google and in this Forum, but no one fixed this problem. I am in Brazil now. Sometimes the phone works. Sometimes not. I am afraid if this could not be a hardware problem. If someone can help some people are with the same problem.
What I already did:
- checked the sim card in other phone and it works ok;
- flashed the original ROM for a brazilian ROM.
I do not know what to do anymore.

Locked phone that your problem,you must hack rom or search code and unlock your phone.
But the phone works sometimes. I do not understand a lot about it, but I thing that if the phone is locked it should not work anytime, or not?
Today I am with full signal on GSM network (and I can register in the network. In others days it was not possible) and it is working in my home. But when I go to other place outside and walk with the phone in the car it not works properly. In this case I just have none or one point of signal and the message of emergency calls appears again. :/ On WCDMA it works SOMETIMES too, but with one or two points of SIGNAL only. Do you think that it is because the phone is locked? By the way, it's the i9505 model. It should be unlocked. I bought it as an unlocked phone to work in Brazil. It is the international version.

One more information: the phone now is working ok with GSM network, but when I change for WCDMA I only got one or none point of signal. What it can be? :/

Hey.. there may be a problem with your network provider.. happened to me too...
I was using vodafone india and i had activated 3g on my n7100.. then i couldn't change to gsm mode. Then i chose another operator (airtel india) and now i can switch to gsm/wcdma irrespective of ny current data pack (2g or 3g)

Xperia M Dual keeps restarting on 3G connection

I hope somebody can help me or can share if he / she is experiencing the same issues.
After searching the web, posting to sony forums, calling support .. w/o any result, maybe someone here has an idea what is going on.
Issue :
At home I have 2 Sonys C2005. One on Official release 4.2.2 and one currently on Cyanogenmod 11 (flashed with the latest firmware available on 7th. September) The first SIM is from Hutchinsons (3 or Drei) in Austria and the Second SIM is from O2 Slovakia. When I switch on the 3G Data trafick on Hutchinsons the phone starts restarting randomly (every 3 to 5 minutes) When I change to GPRS (Edge) , or when I deactivate the Second SIM (O2) then the Phone is working fine. I did NOT had this issues with other Providers. I was before at Vectone Mobile (the second SIM was always O2)
As I wrote before I had tried this 2 SIMs in the second phone with Android 4.2.2 and there is the same issue, the phone starts rebooting. I have called Hutchinson support, they replaced the SIM, checked the SIM profile all is OK. Sony support blames Hutchinsons.. so no FIX on this side either. I hoped custom Android distro could help, but It did not -> CM11 with 4.3 Baseband
I think it is a bug in baseband. (If I understood it correctly CM11 is build on 4.3 Base)
Thx
exact same issue
Servus,
Just bought the phone in austria have a drei and a hungarian sim, same issue with 3g. The phone just works fine when in hungary with 3g enabled on the hungarian sim. Have u maybe any followups on the issue?

LG G3 D855 - only EDGE/GPRS, no WSDMA (3G) or LTE

Hi. Have a problem with my LG G3 D855. It won't work with 3g or 4g - only EDGE/GPRS (2g). I checked on another phone - 3g works perfectly fine there. My Lg has all network bands to work in WCDMA. :crying:
So when i, for example, choose WCDMA only mode, it just loses network connection and starts to look for one. If i choose GPRS/WCDMA or GPRS/WCDMA/LTE - it works only in EDGE (2g). Again, same sim-card - different phone - no problem with 3g.
I thought maybe there is a problem with modem rom. So i upgraded my LG G3 to marshmallow via LgFlashTool. No luck - same problem. I read couple threads, where people have the same problem - seems like no solution or idea, why is this happening, whatsoever. :crying:
Will appreciate any thoughts on the subject. Thanks. :angel:

Network problems

Hi everyone, first sorry for my bad English, I'm from Algeria (north Africa) and I bought a used Tmobile S6 edge plus (sm-g928T), the phone worked fine but it had some overheating issues and was stucked on android 6 with no available updates so I decided to flash it to the stock firmware and I did it successfully using samfirm and Odin, now overheating issues have gone and the phone is up to date but I'm having serious problems using my local sim card, calls work only with the phone set up on "2g only", when it is set up on "automatic" and I make a call I can hear the person but he can't hear me and there's "almost" no internet connection as it's very slow and unstable although the phone has all 3g/4g bands used in my country. Please help
