No phone service

I can not get any radio to work to make or receive calls! I flashed everyone out there and still can not make or receive calls. What method can I use do to get it to work? I flashed radio from TWRP with Factory reset, delvik and cache and then flash with no wipe and I just cant get that or any radio to work. I just get AT&T when I do a scan, which I use T-Mobile. When I choose search in settings in mobile networks, still nothing. When I try to use phone, it always says no network avail. and yes I have data box checked off. It just seams lately any Rom I flash after the newest stock, (JB) I have radio issues, can not make or receive calls. I even erased, wiped everything and started from scratch with stock. Phones works fine, but when I try any ROM, no calls, no matter what radio I flash. I must be doing something wrong. I must say, that I flashed many a Roms before and all worked well until now! I even download same radios in case I got a bad download. I can use kernels, such as Tiberius with Stock JB. I Flash a Rom and no radio, no matter what Rom. My version in stock is UVMC6, SGH T-989 phone. (T-Mobile). I know all phones are different and thought maybe something in stock files I might be able to use, but don't know which files. I am not a dev by any means and thought if I could use the stock I have now can work with the any Rom here. I never dirty flash anything, all Roms work that I flash from sd card, just not able to use phone in any Rom at all! I thought maybe I can manually put in APN, but I have no idea were to get address to enter. I am from Delaware if that matters as far as APN. Can anyone give any suggestions of what they did to get radio to work?

Verify your APN settings are correct. If there isn't a t mobile APN set up than try creating one. Also go to Settings > About Phone > Status and make sure your phone has a valid IMEI number (anything other than 0)

Thanks, yeah after all reading and troubleshooting it seems APN is where I have to create and/or edit! I found APN settings on Google and wrote down the settings that is on stock Rom where phone is working and will try it. Thanks for heading me in the right direction.

[Q] D2ATT and CM 10.2 Loses mobile data

So I flashed CM 10.2 to my D2ATT last friday and was completely happy with it. The snow storms cancelled my weekend plans so I was home with my wifi all weekend. Upon leaving for work this morning, however, I noticed that I was unable to pick up mobile data. I found out through googling that this is a common error with 10.2 so I tried upgrading to a CM11 nightly. For whatever reason my phone doesn't like them and CWM gives an error when trying to install them even if I perform a system wipe.
I tried switching to AOKP and got absolutely 0 service from AT&T as far as cell reception, calls, texts, and mobile data.
I'm back to CM 10.2 right now, and word on the net is that I need a modem file, but I can't seem to find one for my phone. Can anyone get me a link or a fix?
Thanks!

In the SGS III development section there is all the modem files it has it's own thread

I appreciate the response, but I quite frankly have no idea what I'm looking at in any of the three dev forums and can't find the modem file thread. Could you please be a bit more specific?

before trusting on anything
go to your setting-->about and look if your IMEI is still intact

I do have a 15 digit IMEI as well as a two digit IMEI SV. I did however notice that it said "mobile network status: disconnected" so I had it search for networks (it found two labeled AT&T and one was a 5 digit number) and auto select the best one. During that process I received and sent a few texts. After that process it said "selected network" but nothing had changed, and it still said I was disconnected.

I had the same problem when I flashed to stock 4.3, I lost T-Mobile service and only could call and text no data! I flashed the modem from here http://forum.xda-developers.com/showpost.php?p=47817339&postcount=23 only download the modem_ and after I flashed and reboot viola! Data working perfectly Hope this helped!!!

CM11 No Mobile Network, Mobile Network State Disconnected

Whenever I flash cm 10.2 cm 11 any rom at all I face the problem of no internet. So I go back to stock. I have my baseband, build # important stuff like that. I always have to take out my assert lines. So when I flash any rom the fine line will say;
;Mount
or something like that I delete all the assert lines and I was told to keep assert lines but just change them to my baseband and stuff. Any help would be appreciated. & btw the problem is it says Mobile State: Disconnected. But I'm in service too.

I have the same problem. Been searching for a while and trying different fixes, but doesn't seem to be working. I'm on ATT galaxy S3, tho. If someone's got a working ATT S3 and let me know exactly what ROM, gapp, modem, etc they used, would much appreciate it.

More info is needed, such as carrier. I'm guessing either Virgin Mobile or Boost if you need to remove asserts on any of the pre-unified builds (this would hold true for any ROM that has switched to d2lte from d2spr). If that is the case, then you don't have the correct APN's configured. Also, it usually doesn't hurt to be running the most current modem (MK3 for Sprint, MK5 for VM/Boost). Again, the more info the better, then people don't have to play Twenty Questions in order to get to the heart of the matter.

This may work...
So, after trying countless options that i found on this site, and after dozens of flashing roms, modems, kernels, booloaders, restores, etc... turns out that i was doing everything right and there was nothing wrong with the install or the phone itself. After contacting my carrier (PTEL Mobile) for the third time, (first time they told me they had an outage, second time they told me to set the APN setting correctly - neither of which was incorrect on my end or the cause), they said they will try RESETting the DATA on their end. And guess what - that worked.
If you think you did everything correctly but still not getting data, i suggest you make your provider to do the same, or at least pry them as much as you can about your problem and what they can do about it. I wasted to much time and effort (my poor phone) on this and the solution was simple, and not my fault. Hope this helps others.

Hiya, I'm currently having the same problem as the OP. Mobile state disconnected but it says I am in service. Using latest version of Philz recovery and I flashed the most recent nightly of the Cyanogenmod 11 -4.4.2 KitKat (April 5th, 2014).Carrier is Virgin Mobile, using Samsung Galaxy SIII SPH-L710. PRL is most recent one 33030 and modem is MK5. I did however, flash the rom without deleting the assert lines, since I did not know I had to delete some assert lines. Any help with this? Thanks.

Deleting asserts is only for d2spr specific builds, that doesn't apply to d2lte builds (hence the reference to "pre-unified builds" in my first post). Your issue is most likely also related to APN's. However, there are also known data issues on a lot of the latest CM nightlies, and also on the ROM's that rely heavily on CM as a code source. I would strongly recommend reading the last several pages of the thread for any ROM that falls into this category in order to see what other users are reporting along these lines.

CM11 No Mobile Network
Hey guys,
Noob here. I'm running CM11-20140428-NIGHTLY-jflte on a Galaxy S4 GT-i9507(international, optus) but bootscreen now says 9505(not sure if that's important).
I've had Mobile Network State: Disconnected for the last three nightlies. On CM11 M3 it was working all good, but now no luck.
So I've tried a few things and I've come to the point where I'm going to try the factory reset then reflash CM11 and fingers crossed it will work.
Can anyone talk me through the proper procedure for this? I've made a full backup on my external SD using CWM 6.0.4.7 and transferred it to
computer just in case. So would anyone be awesome enough to take me through it step by step.
Cheers,

hhmmm

Stock no APN settings at all
I have looked everywhere and found nothing for the last 3 weeks. I have a stock, sprint S3 on straight talk (my son's phone) it will not get 4g lte data what so ever. My phone is the exact same phone, and it does get 4g lte data. I tried all the basics ##72786# data on off check airplane mode...nothing. Mobile network state is "disconnected". So I opened data ##3282# to compare apn settings with my phone. I made sure everything matched, and when I get to "LTE APN Settings" I open it up, and nothing is there except APNs nothing, blank. Also missing is "Dial Up Networking" that option does not exist on my son's phone. He updated to kitkat (uggh) but the problem was present before that. Checked the phone, and it is not rooted. Funny thing is the phone updates with 4g lte running after dialing ##72786#, but that goes away after it completes. Texting works, but no mms (pictures etc.) and if I set it to cdma only it gets 3g, otherwise no data at all. Anybody?

Can't make calls out (Random only on network mode WCDMA/GSM (Auto Connect)

Hi.
I have a Samsung Galaxy S3 T999 model on carrier T-mobile. Lately the phone has gone nuts and will get stuck on dialing out and will never make the call. Everything else works fine. Sometimes I have to soft reset, pull the battery and that will fix it for a call or two, then it will get stuck again. I have contacted T-mobile about this over 5 times and none of them can help. We tried to change the sim, reset the account. Etc and nothing. I have reset the cache, factory reset and even put in a good working sim card from another phone and the same problem comes up. During my latest troubleshooting I have narrowed it down to where I switch "network mode" to GSM only and that can make calls out all the time, but the data stays on E (which then I can't use the internet because it's so slow) When I switch back to auto I am sometimes able to place calls again, but only a few. After I test a few calls and leave the phone for a few minutes the phone will get stuck back on not making calls out and just saying "dialing".
Has anyone had the same problems or know of a fix? Currently I have been trying to flash the modem to different versions to see if that fixes the problem. The first two modems I have flashed did not work and came up with "unknown baseband".
If anyone can help I greatly appreciate it.

This is a known issue with 4.3.. What firmware are you on? Assuming you flashed the correct baseband for your device, the 'unknown baseband' message sounds like you are in 4.3 but what build? You can't flash any modems successfully less than 4.3

I was previously on 4.1.2 when the problem first started. I updated it to 4.3 and still the same problem.
jss15j.t999uvuenc2 build. (I put this one back on last night so at least I can use the phone today when I am at work)
I was just hoping that the device didn't go bad when it was on 4.1.2 because it was working just fine before the problem started.

Was it official update to NC2 by OTA/Odin or you just flashed a ROM?

NC2 was OTA. After doing some searches it said that OTA could of been corrupt, so I went and downloaded KIES and did a reinstall that way.
When I upgraded to 4.3 I tried that default baseband out and had the same problems. That is when I was searching on google and came across this forum and also the thread about flashing modems.

What APN (Access Point Name) are you on ? Also what is your Preferred Network Type set to ? Its located in Settings > More I think.(I don't use Stock Firmware)

APN is epc.tmobile.com
Network Mode current set to GSM (the only way I can make calls out without the problem occuring)
WCDMA/GSM (Auto Connect) is what it should be on so my data is at 4G, but the calls is the problem here

I am not sure but can you check the settings of the Dialer to see if there is ways to choose Lookup providers ?

Nope don't see anything in the dialer about selecting a provider..

Its supposed to be something about Choose Lookup Providers. At least that's the way it is on AOSP.

I suggest Odin flashing the stock NC2 firmware and then factory resetting from stock recovery. (Backup first of course!) If it is still an issue, it will most likely be a hardware problem. From what you have said so far, I believe that you will find this to be the case. Could've been due to damage from a drop, or even overheating at some point. Or it could just be that its simply due to hardware degradation over time.

Unknown Baseband after flashing rom

Okay so i have the T-Mobile Galaxy s3. It has been rooted for a while with zero problems. I got tired of the older android on it and decided to install a rom. I installed Cyanogenmod 13.0-20151208-unofficial-d2tmo running android 6.0.1. When i first got it all booted and loaded with gapps, i noticed that it recognized my sim and that i had a signal but i couldn't use any LTE or just all around data. basically i couldn't go online (in case i just didn't explain that well enough. Phone service is a mystery to me). I did some searching online and found a lot of people saying that i needed to update my baseband. i found a baseband for my model (T999) and tried to flash it in TWRM. Once i rebooted, it said "No SIM card - No service." in the upper left-hand side. i have tried flashing multiple different basebands the same way with no luck. i tried backing up my EFS folder and the restoring it because someone said to do that and that just... just no... it didn't do anything. even Odin 3 said it was a "FAIL!". So here i am with this android equivalent to an Ipod and i hate this. Everything else in this ROM works perfectly aside from this but this is a super big problem. PLEASE HELP!!!! A phone isn't a phone if you cant even send a text.

Did you update the phone's bootloader and modem to the latest version before flashing CM?
