[Q] network issue - Galaxy S III Q&A, Help & Troubleshooting

First, Hi. I have a Galaxy S3 International Model, I live in Turkey and I installed the ROM Cyanogenmod 11. Is very smooth and fast and simple which I like but my network conection comes and go. Is like it comes but immediately it goes. So i don't have Data nor signal to make calls/SMS.
And the most strange thing is that I have the IMEI in the phone, just that my network connection leave and come. But comes for only 5 sec, so it is always with no network status. I made an EFS backup and restore it but no results.
I would be really greatful if someone can give me an answer.
Cheers,

Flash another modem

Check your apn settings match the ones for your carrier, sometimes these get deleted or not carried over when you first flash the rom.
I would hold off flashing another modem especially since cm doesn't touch the modem and it will still be the same one from your stock rom, assuming you came from stock of course.

If you want help you must provide relevant info - and also be able to think a little for yourself!
Have you done anything special to the phone before that? Like programming a ROM in Odin?
Is the IMEI in place?
im new to the s3 and dont have a clue about what anything is. ive never done anything to it.....

Hi I think this may be an issue in some parts of the world, but not all. I have regular signal cuts like this in South Africa, but generally only when I'm in an area with weak cell signal. My wife also has a S3 LTE and gets the same signal cuts. When it happens I reboot my phone and it's fine again. I even went back to stock to test and it still happens on stock, just as it did when I first got the phone in November 2012.
I've been on AOSP roms the last few months and then it was fine, no signal cuts. Same with my wife's phone. Now I'm back on stock and the signal cuts are back, albeit not so often anymore, maybe one or two a week. I'm going to run stock for a few weeks and see if the issue persists.
What modem are you using? Have you changed it or is it the same modem that came with your phone?

a MODEM IS A MODULATOR DEMODULATOR . basically the bit that connects to the network .
Modem = Baseband .
\Suggest one factory reset two if that fails service centre and three read the basic faqs and guides .

specially if i tether my phone via wireless
i have changed its software (rom and modem) and I am still experiencing this loss of network
in order to get network again I must reboot the phone, it is the only way of getting it back working
I travel a lot to Portugal and take the phone but I do not seem to have experienced this there
tough i dont tether there nor i use the connection for data
currently i am using a slim rom 4.2.2 build 8 official
the baseband is i9100xxLs9

Modem is what the culprit.

Hi! Thanks for the reply!
I already tried that. I reflashed and put a new modem aswell.
It improved the simptoms but they still persist
Any specific modem that you think i should try?
Some times my phone freaks out and just gets corrupt and i have to reflash
Do you think it might be going to die? Maybe replace it?
Best regards

Put it on gsm mode which is also called 2g mode.
Monitor it if you still loose signal.
If so, then i would recommend you do a clean wipe, use any rom wipe script available and then install your rom back

Slimkat Network Connection problem

First, Hi. I have a Galaxy S3 International Model, I live in Central America (Panama to be precise) and I installed the ROM Slimkat. Is very smooth and fast and simple which I like but my network conection comes and go. Is like it comes but immediately it goes. So i don't have Data nor signal to make calls/SMS.
And the most strange thing is that I have the IMEI in the phone, just that my network connection leave and come. But comes for only 5 sec, so it is always with no network status. I made an EFS backup and restore it but no results.

[Q] People ringing me but the phone doesn't ring while saying "Emergency Calls Only"

[Q] People ringing me but the phone doesn't ring while saying "Emergency Calls Only"
Cheers guys! Hopefully i won't be boring you much!
I have this Blue S3 GT-I9300 16GB unlocked. Last week i flashed efeXtreme ROM on it but due to overheating, battery draining and lag, i decided to revert back to a stock ROM. And that's exactly what i did. Can't remember exactly which but it was a 4.3. Anyway, while using the phone with that ROM, i could actually see the phone's signal going down and in a few seconds the phone would say "No Service". At first i thought it was the network / carrier. Tried a Meteor, a Vodafone, an O2 and my 48 SIM card. No difference. So the problem was clearly the phone. And since then the same problem. The funny thing tho, i live 10km outside the closest town, where ironically when i go to, my signal is full, H+ full signal. And when i return, the further i am from town the worst my coverage is, so basically, halfway home and my phone's stuck on No service. With any other phone that i have in my house, S5, Nokia 5230 and an N90, there's no problems.
And here i am now, tried flashing a 4.1.2 stock ROM, nothing but problems. Flashed a few radios, modem_RIL_CWM_I9300XXEMC2, modem_RIL_CWM_I9300XXEMG4, modem_RIL_CWM_I9300XXEMG5, none of them helped. Flashed the Siyah Kernel. No difference. Even lost my IMEI and S/N twice, which weren't a problem for my Z3X. And now, my Mrs. is ringing me telling me the call rings out with no answer while my phone never actually rings and the status bar keeps saying Emergency Calls Only. And BTW, Emergency Calls is permanent now, home, in town, everywhere. Any ideas? Maybe a Custom ROM could help me? Please help me out here lads. Thank you!

Emergency calls is permanent now because constantly flashing from 4.1 to 4.3 as corrupted your imei without a efs backup your only hope is a patched modem and kernel. If that does not work then it is service repair.

Thanks for your quick reply. You see, the EFS is not a problem for me as i can flash, wipe, rewrite it with my Z3X box. With it i can fix Wi-Fi MAC address, Bluetooth MAC address, S/N, IMEI. When my IMEI number first switched to 0049xxx i just changed it back manually with the box and the phone worked fine in town. But i was still hoping i'd make it work at home too!
About the patched modem and kernel. Can you please elaborate on that? I could really use all the help i can get!

When Samsung introduced 4.3 it changed the efs from efsv1 to efsv2 basically to cut along story short this meant in some cases the efs could not read 4.1 modems and in some cases where the efs got corrupt it could not read efs v2 modems as well. So there are some patched modems and kernels in the forum that allow the efs to be able to read the new modems. Look here >> https://drive.google.com/folderview...sharing&tid=0B6MIUd7HJudAbU5YaGkzOUowMG8#list << you need to flash the kernel and modem for it to work (although it doesn't work in all cases)

That's brilliant! Flash a 4.3 stock, and applied the patched radio and kernel. The phone is back to square one now. Which means, i get coverage in town but nothing at home. And 2 weeks ago the coverage at home was decent. Any suggestions for that?

Try a different patched modem from the link I gave you their are a few to try. Obviously the patched modems are working because you can get coverage in town if they had failed you would not get coverage wherever you are. Sounds more like a network problem then the actual phone but like I said there are different modems in the link so one might work better than the others depending on your country etc.

Network Signal issue

Hello, Im having some problems related to my Network signal (GSM not wifi).
The thing is, once i come here to my frat, i barely get any signal, even thought i had installed an app and it said the nearest antenna is like 150m from here. I had tried to connect manually but it didnt worked. What usually works, is to restart my phone (turning airplane mode on/off doesnt).
I dont know if this is the right place for it, but i want to know if someone here at the forum might know a kernel or a script that might help me solve this.
thanks
I have a similiar issue.
Where i should get more signal (city center) i get very low signal instead.
Meanwhile at home,where i live a bit far from the city i get all the signal.
Maybe we need to flash some sort of radio firmware?

Flash again the modem files
idk man... i was think about an auto reset script... something like "connect to this network or reset modem services/try again" cause most of the times, the signal works when i restart the phone.
Either way, idk if thats possible. Im no newbie at phones, i mess around a lot but i only apply scripts, roms, custom recovery, etc and not develop them.
Which ROM you are on?
