Mobile Network Not Available

Hi guys randomly yesterday I got a problem where Mobile Network is not available.
I have 4g signal and can use internet but can text or phone call. I have odined the stock666 file and did some dial code but still didn't fix it. I also flashed back to stock and tried removing and inserting sim but still same problem.
any ideas?
I can receive texts but cannot send any. it seems like a weird network setting on my phone.

I tried doing a factory reset and tried even swapping sim cards... no go

Hey, I'm on T mobile and also having the same problem no mobile network. I'm using S3 international , tried to switch SIM to my note 2 international but still no mobile network.:silly:

i have spent hours trying to fix. let me know if you find a fix. phone is unusable

Try this, go to open1your1eyes0 thread for Stock Jelly Bean Factory Images http://forum.xda-developers.com/showthread.php?t=1974114
Go down to VRBLK3 Image Downloads (Official 4.1.1 OTA - Built on 11/30) and click on show content. It should have the Stock odin for VRBLK3. Odin that image and see if your mobile Network works then. (watch out, it wipes everything, relocks bootloader etc) Also try to get a screen shot of your status screen in about device so we all can help you better. It could be a IMEI issue, but hard to tell. Were you using a custom rom at the time? Which rom? Is Mobile data enabled? Preferred network mode to LTE/CDMA?

I have seen several instances where the newer versions of CM have had network issues. I'd recommend backing up your files, wiping everything, and trying another ROM. If that doesn't work, it sounds to me like it could be a hardware issue. Best of luck.

Check and see if your IMIE and or ERI numbers have been reset. If you are with Verizon I believe that your ERI number should be 5. I had this issue happen as well. If you have a nv backup just use terminal and restore it, if not look here. This is how I got mine back. http://forum.xda-developers.com/showthread.php?t=1867442 My issue was identical I was on 4.2.2 CM10.1 and could get on the web and receive text but couldn't send any or send or receive calls.

first 4G phone
I just got the phone today and i can't call or text anyone because there is no mobile network available and I need to put a sim card in. This is my first 4G phone and I don't have a sim card. They didn't give me one either.

If you're on Verizon (I'll assume that) and received a phone thru them, the SIM card should have been in the box with the phone. If not you'll need to go to a Verizon store and they'll provision one for you. You'll not have service until you have installed the proper SIM card.

We need a little more background, Lucas. What have you done to get there? Are you rooted? What ROM?
I've had network issues a few times, usually I resolve them using the "Phone Info" app, but it's a little complicated, so I'd rather hear back from you as to how this all started before I get too specific.

For the people with service issues, it's been asked but no on really answered unless I missed it. Does your IMEI say 0 instead of the number that's under your battery? Does your ERI say None instead of 5? Under mobile network does it say Verizon? Also, sign into your Verizon account and under your phone instead of S3 does it say non-vzw device? If so you you've lost your IMEI and ERI. There are a couple of different ways to get it back if you didn't make a backup. I haven't done it but alot of XDAers stated using odin to get back to stock and I hear reprovisioning your phone with a numerical keypad entry on the dialer worked. Here's what I did.
1) Flashed a stock rooted TW rom.
2) Used this thread and software to get my imei back : http://droidmodderx.com/galaxys3/?page_id=79
3) I had my IMEI back and on my account my phone read S3 but I still had no ERI.
4) Follow these steps here, the previous posters thread won't open because XDA can get in alot of trouble from having the Samsung Repair Tool on it, or so I hear : http://forum.xda-developers.com/showpost.php?p=44871571&postcount=3
5) You can find what you need there. The tool won't work without a downgraded modem, well at least for me it didn't until I did.
6) I forgot a step in that, once you're back you've backed your IMEI you can then upgrade your modem back to what you want.
Hope this helps

Actually I did some research and figured out that my problem is that my IMEI was lost after the ROM flashing. That is the reason I can't make calls nor send texts...
Now I am trying to find some way to fix it. I did not have an /efs backup so my task is complicated. x(
Anyway, thanks for your help! =)

Tell us what ROM! if it was CM10.2 Go flash a different ROM and you'll be fine your IMEI isn't really lost.

Anyone figure this problem out? I'm having the issue with my GS4 after flashing CM 10.2 nightlies. I've gone back to stock everything, and still no service. I can't send texts or calls. It now just tells me I'm roaming all the time. I'm going back into verizon today to get a new SIM card. Hopefully that will help.

The link u posted is no longer available. Or explain what steps to due to fix this on my s4 Verizon l545. I'm having the no network available w calls and texts but I am able to text just no calling. Thanks
Update: Oct. 1 2013. I was able to fix my issue by doing a factory data reset from settings. I was running Hyperdrive rom, w TWRP 2.5.0.2. I did do a nandroid backup before doing this but then an update in Hyperdrive was available so I just did the clean install after that and was good to go. My problem started when attempting to do the hidden menu sim unlock free method. So if this happens to u, u should be able to try this method and get calls back, but Im not sure about unlock status.

Can't call my girlfriend!!

I have this strange problem since 1 month ago more or less.
I'm not able to make call only to my gf, it's the only number I can't call. I can text her (sms and wa) but not call!
I tried to reset and change rom and kernel to my NexusS, and I also tried to reset her galaxy ace, and to delete my contact from her list.
nothing.:crying:
any idea?

If you REALLY did that, then it might be a network problem, a radio problem, or someone cursed you both.
But i think it's a network problem. Can you call other contacts normally?

Maybe try changing your radio! If that doesnt help call your provider or call somebody in the same network as her!
But maybe theres a reason you cant call her? (jk)

What happens when u call?
Nothing?
Voicemail? Or
Something else?
If voicemail then it could be her phone that has ur # set as "send call directly to voicemail"
If nothing then its ur phone... But if ur able to make other calls then try dialing her number with the 1 in front of area code then try without. It could have been changed somehow.
Lastly, do either u or ur gf use Google voice or any other service besides ur phone company? ... If so check those settings just to make sure.
Good luck

i cant tell you which to flash cause it depends on your area. i used to use the kb3 because i had faster internet and better connection with it... but i moved away and i didnt care about looking which works best.
but it does seem more likely that theres sth wrong with your girlfriends phone...
good luck!

well thank you all for the replies first of all!
I had a look at her phone yesterday and there's no "send to voicemail" option activated, it was the first thing I tried.
She has no apps for blacklisting contacts and, at first view, no option to do that.
we both can make call to everyone, and she can call me but i can't call her: when I try I hear for a moment the "tuu" sound (hope you understand what I mean) then the typical sound of call terminated.
I'm pretty sure it's a problem related to her phone. It has a GB 2.3.7 custom rom installed by me last year, I never updated it but it always work perfectly!
I will try a different radio just for trying to speed up my internet connection, I don't think it can be related to this problem too.

Or call your provider.

Maybe your Nexus is trying to tell you something.
Lol, anyway, check both phones, Google voice, and carriers for any sort of blocks. I know that on some phones, it's easy to accidentally put someone on a block list.

Phone instantly disconnects

Is anyone else experiencing calling issues? Often, I'll dial a number or tap an address book entry and it immediately hangs up. Both with headset in and out. I can reboot and that sometimes fixes it temporarily, but not always. Very frustrating! Anyone else experiencing this? Thanks.

I have the same issue. I noticed it happens when mobile data is on. What model are you using?

T-Mobile D6616. I spoke to TS, they suggested disabling VoLTE, and rebooting. I did, and made 1 call successfully, but obviously it will take more time to determine if this is a real fix....

I've experienced this. A quick reboot resolved it for me. I haven't had it occur often enough for it to be a real problem.

Callers unable to hear my voice, seems muted or broken

Hi Guys,
Have had my S7 SM - G930FD (dual sim) for a little less then a month but have run into a major issue.
The caller is unable to me during phone calls. Have tested with the head set and on speaker phone and these seem to be working, although with speaker does seem to have echo. Also during normal call, I can hear myself on the S7.
Phone was a grey import from EBAY, country of origin is UAE and I am based in Sydney, Australia. I haven't changed any of the stock software. Its running on 6.0.1.
Have already tried factory reset.
Anyone has run into this issue? Haven't found topic regarding this issue. Or any ideas for solutions or if it could be hardware or software issue? Have never dropped the phone and has only briefly been in contact with water.

I think if you try to flash stock rom it could fix the issue, if not id say it is a hardware issue rather then software so id recommend you to take it into Samsung to get it checked or even replaced as it could be faulty
If you are willing to reflash stock rom onto your S7 here is the website that you can get the correct file http://www.sammobile.com/firmwares/ just insure that you put in the correct model number when searching

Question Flip 3 Cover screen Call notifications

Hi, got mine on Saturday and noticed one thing: The cover screen doesn't show an incoming Whatsapp voice or video call. You can only answer telephone calls from the cover directly via loudspeaker. Same for duo. I can't access a call from the cover screen. Can anybody confirm this behavior? Not even showing the Whatsapp ones is really annoying... I am lucky that my Garmin is connected and at least will show it on the watch

What carrier do you have? what Software version : Settings> About phone >Software information (last 4 digist of Built number) ? Do you have the latest version of Whatsapp and Duo?

I am a user in Germany. Using "Deutsche Telekom". Haven't received an software update yet, still on XXU1AUG7. Apps are always up to date.

I have to disagree. This is my CSC...
But I will also attach the SPSV.

@Cris7ianO CSC as in region of your phone, usually it's DBT for Germany. What you show me is firmware csc, but OK. Whatever you say.

No problem. Then we were just talking about different things . Got the device as a preorder from Samsung's German website. Unfortunately no DBT to be found. But how does this have anything to do with the issue?
Don't you experience the issues mentioned above and the cover screen shows the incoming call notifications for Whatsapp and Duo?

I wanted to compare csc with mine, because it's seems not OK. That's why I said please. You can find region CSC if you look at my screenshot. About your problem, no, it doesn't show calls from the apps you mention on my phone either.
