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.

[Q] switching the phone to "emergency calls only" state

Hi everyone, just found this forum when i was looking for help on this model of Huawei phone.
Huawei ascent mate 7, it is a great phone so far and i am very happy with its battery life. There is an issue which is very annoying but i just simply cannot reproduce this problem when i want to. so yes it is a random thing but it does happen at least once a day.
it happens when i need to make a voice call, or when i am being called. the phone turns itself into "emergency calls only" mode after the first 5 seconds of conversation. and it will not switch back online until i turn on and off the flight mode.
EMUI 3.0 - MT7-L09V100R001C00B120SP04
I had my phone replaced once, also changed the SIM card from my operator. but it still happens.
i dont think it is a network thing as i have been using this mobile network for a while and when the thing happens i am usually either at work/home, the places that i normally go daily.
anyone has experienced the similar issue with this phone?

An update on this issue that it only happens when LTE is allowed on the phone. When it is required to start a voice call the phone changes its state to 3G (which is what it should do), apparently that there is a handshake problem and it loses its network occasionally. I changed the phone to 3G+GSM only and i have not experienced the same issue yet, so far (for half day). I am not sure if it is a network thing or the phone's. I wish that there a new firmware to fix this issue as it is too annoying...

Random reboots and echo in call volume.

Hello Guys,
I am facing this issue on my E6683 since last update on Nougat update (32.3.A.2.33).
1: Random Reboots:
I had repair my device using the xperia care app and I had a fresh new phone. But after using for few days installing some apps the phone suddenly start rebooting automatically. Also there are many application which are dying every time, the phone is not running stable. Every time it reboots it takes around 10 minutes to boot the phone. While rebooting the red LED light blinks 3 times and again reboots, this will happen at least 3 to 4 times then the phone will reboot.
2: In call voice echo:
All callers calling on my phone are complaining that they get a echo of their own voice when ever they call me. I am bit frustrated about this and not able to find the solution.
Using a Sony flagship phone and experiencing such things are not expected. could any one help me to get rid of the issue.
Try to find some solutions i had unlocked the bootloader and tried flashing the stock firmware still the same problem.

Could be that you got a "lemon" phone with hardware issues (faulty RAM or storage),
1) how hot is your device getting under usage ?
This instability gradually also appears if you only install few apps ? (try to install as few crucial apps as necessary, the bare minimum)
Is there some connection with the battery charge and state (e.g. each time around 30% or 15 % it happens) ?
Do you have battery optimisation enabled ?
2) How are you calling ? via headphone, noise-cancelling headphones ? via speaker & mic (traditionally) ?
what sort of network ? (3G, 2G, LTE) - how is network coverage ?
single SIM, dual SIM device operation ? (how many SIMs are used ?, what SIM card is having that trouble ? if only one - you tried switching the SIMs in the slots ?)

--> Normally this device is stable, only playing some heavy apps/games causes the heat.
This instability gradually also appears if you only install few apps ? (try to install as few crucial apps as necessary, the bare minimum)
--> Yes I found this in the Facebook Chat App and Google Play Services App, when ever i install this 2 apps the phone starts rebooting randomly. right now i have removed those apps and the phone is working fine...
Is there some connection with the battery charge and state (e.g. each time around 30% or 15 % it happens) ?
--> NO
Do you have battery optimisation enabled ?
--> Yes
2) How are you calling ? via headphone, noise-cancelling headphones ? via speaker & mic (traditionally) ?
--> Traditionally via phone mic n speaker.
what sort of network ? (3G, 2G, LTE) - how is network coverage ?
--> LTE network, the network coverage is always good.
single SIM, dual SIM device operation ? (how many SIMs are used ?, what SIM card is having that trouble ? if only one - you tried switching the SIMs in the slots ?)
--> Dual sim operation, with 2 SIM I tried in both slots same problem.

*) Okay, so for Facebook:
you can choose a browser that fits your use and use that (it's not optimal but that's what others in that situation do),
*) Google Play Services: you can try and update it to a newer version and see if that works better
http://www.apkmirror.com/apk/google-inc/google-play-services/
#) regarding the echo issue - could be that there's an issue with your phone, modem, etc.
You could try flashing a Nougat firmware from a different region if that changes things (via XperiFirm)

RMA ?
seems there's a hardware problem - if even fastboot or flashmode doesn't work

Finally got mobile hotspot working. 7.0

After suffering with no Hotspot for months, I finally figured out the SIM pop out method it reply does work, but during that process I also downloaded a Wi-Fi Hotspot widget (no ads) and it basically turns on the hotspot with one push if the widget. Please confirm that it works on your LG G5's. Good luck with it.

Ok, just restarted the phone and the widget won't work until I do the SIM pop out trick, then the widget will work until the phone is shut off again. Maybe somebody can exploit that so we won't have to pop out the SIM every time.

Hi.
after update to V500N20w I can no longer make calls or connect to the internet! explanations :
the first 10 minutes after switching on the smartphone I can make calls and connect to the Internet too, but it heats up a lot near the ignition button, after 10 min I cannot make calls or connect to the internet.
the solutions I tried:

- I changed my sim card always same problem
- I chose GSM only mode and now I can make calls without problem and without overheating !!
- with 3g or lte mode I have the same problem at the beginning
