I own an GALAXY S7 EDGE AT & T ( G935A )
Yesterday on morning i was talking on phone and after 1 minutes 17 sec phone loses carrier signal and after 2 sec of losing signal the phone reboot automatically then was very slow. I rebooted the phone, and it showed that havent SIGNAL there and instead CARRIER SIGNAL i see the circle with diagonal line there.
I wait some minutes for the signal but again the same, i make some restarts but again the signal doesnt work, just displayed circle with diagonal line. Then i make RESET FACTORY and after configuration was the same again, i update to nougat 7.0 but again was the same error, i downgrade to ANDROID 6.0 but again doesnt work.
The wi-fi works perfectly with no problem, but I can't make a call, send sms, or mms, or use mobile data like 2g 3g 4g lte or gsm.
Any ideas how I can turn the radio on? I've rebooted several times and toggled the Mobile Data button, but that isn't doing anything.
Other details are:
In SIM CARD status:
NETWORK: Unknown
SIGNAL STRENGTH: -113 dBm 0 asu
Mobile Network Type: Unknown
Service State: RADIO OFF
Roaming: Not roaming
Mobile network state: Disconnected
MY PHONE NUMBER : Unknown

Have you looked in system settings to verify that your network/SIM settings are correct?
Here are some dialer menus for S7 and S7 Edge. You're looking for the menu that let's you check the status of your radio and allows you to turn the radio on/off. See if it will let you turn the radio back on.

Also, try a different or new SIM.
Are you sure your service wasn't disconnected by your carrier? Have you called support?

If you read their first post, they still have their IMEI number, it is still listed where it is supposed to be in settings.
Checking IMEI would have been my first suggestion also but they have IMEI so I didn't bother mentioning it.

Did this just happen on its own, did it happen after you updated the device?
If you bought the device used and you ran into this issue when you tried to activate it, it might be a device that someone didn't pay the phone bill and the devices blacklisted. If this is the case, there's nothing you can do until/unless the previous owner's existing bill is paid, then the block will be removed.

Hi, I don't know what the hell has happened to this phone but after looking at it I can see there is no IMEI, no APN settings and no signal.
The phone has recently been unlocked from Orange to allow the use of an O2 Sim card. Using one of those internet unlock sites. It has been working fine for the past 2 weeks since unlock.
I don't really know what information to give;
Signal: red circle bar
APN: empty, I tried to add an APN to the list but it would not save. It just goes back to an empty screen.
Network: unknown
signal strength: 0dBm 0asu
mobile netowrk type: unknown
service state: out of service
mobile network state: disconnected
IMEI: Unknown
IMEI SV: Unknown
Any help would be awesome

im having the same problems but i managed mine to detect and display my network name but still no signal
i am seeing my imei and imeisv (20)
dial this on the dialer *#*#4636#*#* and in that settings go to phone info scroll all the way down make sure radio is on
and select gsm only but thats as much as i can come up with im stuck still with signal strength 0 dbm 0 asu
ok i was doing some reading. and i found it to be possible that the phone doesnt have the apn settings for all networks in built, so putting in your current carriers apn settings manually should work, im going to try this to see if it works, i just saw the part where you said you tried this but it wouldnt save, still going to give it a shot, mine was also unlocked from orange to use on digicel jamaica networks and it worked for about 2 weeks, then BAM! red anti circle for signal or circle with slash through it or cancel icon. and nooooo signal none whatsoever. but with the *#*#4636#*#* settings i managed to get it to display my carriers name when i drag the notifications menu down. i dont know if flashing the radio will fix this but i was told this moto cliq has the latest radio already. still searching for solutions
this problem is all over with 0 solutions lol

I managed to solve the problem a couple of weeks after making the thread by simply rooting it and installing a custom ROM, I think it came with a radio flash as well but can't remember. It's my sisters phone and it seems as though she hasn't had any problems with it since then so all is good.

I am new to rooting. After over 2 days of unsuccessfully trying to install android 4.4.4, I finally did using clockwork and nightly's 11 cyanogen kitkat mod with gapps. I have a Huawei Ascend Y300. My mobile network, before rooting (?) was Bell [Canada]. Now, it doesn't seem like I can connect to mobile networks like before. I cannot send nor receive texts and calls, making things very difficult. I'm definitely new to rooting, so I have no idea what the language of this business is. I really do not want to have to go back to factory resetting because getting 4.4.4 to work was the biggest pain I've had to deal with yet with my phone, as it soft bricked and everything.
I'm not on a data plan, so it's not like I use my phone for its own wifi, but just the regular connection for texting/calling doesn't work. I think this feature was unavailable to me sometime after I rooted my phone. The mobile network became unavailable (I think) sometime between it being rooted, but definitely before it was upgraded to 4.4.4.
How can I fix this problem?
Below is my phone's status. Note that the Imei is available, but the parts that include mobile networks are unavailable.
Battery Status: Not charging
Battery Level: 21%
Network: Unknown
Signal Strength: 214783647 dBm 255 asu
Mobile network type: Unknown
Service Status: Out of service
Roaming: Not roaming
Mobile Network State: Disconnected
My phone number: **********
IMEI: ****************
IMEI SV: **
IP address* **********************************
Wi-Fi MAC address: **************
Bluetooth address: unavailable
Serial number: ************
Hi
Thanks for writing to us at XDA Assist. Exactly which ROM did you flash? Where did you find it? Please provide a link.
No response in two days, thread closed.
Hello guys,
My n8000 seemed couldn't connect to a network.
It has happened since 6 months ago.
The signal shown a full bar, and the SIM toolkit application of the sim card that i inserted is appeared, and also in network setting it show the APN of my network
When i search the network, various network poped up, and i can select the network just fine.
But when i tried to call or do something network related, it always shown "Network Not Available"
I have switched SIM card to various provider but it doesnt change anything
I use
Gnabo v7 ROM,
Android ver. 4.4.2.
And boeflla kernel
My tab has history of "hard modding" in which i used to mess with the efs, broadband and imei number.. but it had been restored
Now my IMEI number is 00499xxxxxx
I think the problem is from software/system related, not the hardware problem.
Is there anyway i can check which component is messed up?
And is there anyway i can fix my problem?
Sorry for my bad english
thanks

First I would check if the IMEI is possibly black listed, maybe here: http://www.imeidetective.com/englishaparativbazi.php
If not I would go back to stock and check if network works.

Sounds like a corrupted EFS partition. Do you know if its ever been rooted or anything like that?
Check in Download Mode to see which model S7 it is, the demo phone S7 model is G930X
No I don't know about this.Please can youhelp me
Turn the phone off, then press and hold vol down + power + home, this boots it into download mode. In the top right is a bunch of phone info, including model. That model will tell you if its demo or not.
