Hi everyone,
In my xperia neo a network the problem started 3 days before
first it was showing the sim and network and i was not able to make any call and then i changed the sim to airtel and it worked for two days. after that it also stopped, when i switch on the phone it initially shows network and after 5 mins it changes to "emergency calls only" but when i search network manually it detecting all networks but i'm not able to register on the home network. it shows network unavailable.. and sometimes network automatically comes and sometimes it automatically goes.....
please help me on this ?????
is it a software or hardware issue??
as i bought the phone from middle east the sony guys are not taking it for service here in kerala
thanks in advance
My J (bought new, no smilock or net lock) suddenly lost signal and can't register to network anymore. The same sim can register to the network on other phones, and other sim cannot register to network on my J.
I tried to reset the device changing also firmware but it didn't help, after some time I insert the simpin (could be few seconds or few minutes) the signal is lost and the phone can't register to any network. With a network scan it finds all the available networks but it cannot register.
Is it a known issue? What could it be?

Have you tries another sim card?
Yes it doesn't work. But finally I figured out what was the problem. My provider blocked the imei, apparently without any reason.
Hi there I have the same problem what you have mentioned here.My other sim cards too donot work on my LAVA XOLO A500. I guess my provider too has blocked my imei for no reason.:crying::silly:
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.
as the title says , am getting a network signal in the status bar with no sim card installed in the device , where it used to show a stop or block sign before when there is no sim installed , don't know when it started but i have noticed it a week ago , and am on the 5.1.1 update ,
what i have tried so far :
1 - reset the device from the setting .
2 - reset the device with samsung smart switch for windows ( which download the latest firmware for the device & install it ) .
3 - installed the factory firmware with odin , and got the device to axiom telecom which is my warranty service provider , and the told me the have changed the whole motherboard , & after telling them the issue is still there , they showed me another s6 with no sim and there is signal and told me that this behavior is normal ( which i don't think so ) .
4 - contacted samsung directly by phone & email , and they told me to reset the device or send it to service ( which i already did ) .
so , is this behavior really normal ? are any of you guys getting this ?
my device : SM-G920F
country : Saudi Arabia
no its not normal
if you type *#06# you gonna find IMEI become 3500000000006/01
if it is then you cant make calls or send sms ( not registered on network )
its the same problem like me i don't know where this come from but we need some one to give us backup the EFS folder. to restore it back to the phone SM-G920F
please if some one can help us thank you

no , it seem we are having different problems ,
*#06# reveals normal IMEI ,
and i can make & receive phone calls & sms if i install a sim card ,
try resetting yours to stock ,
other than showing a signal with no sim card installed the phone is fine & doesn't have any problems .
Speculation- you'd need emergency service call? I would assume that it's allowed to connect to network for that and not have phone disabled?
More speculation- your being spied on...
-Spy
It's only a display icon. You aren't able to still make a regular call without the sim? If it ain't broke don't fix it.
But to ease your mind just check the network status in your settings. Should say what connected to.
Surely it does have to do with the update itself if your phone still functions as normal.
I'm sure there is a network status with the super secret spy codes that you enter on your dial pad. You know the #secretrandomnumber#* codes...

it could be there for emergency calls ,
in terms of being spied on , ha ha ,i don't think so , the service center changed the entire motherboard which include the eMMC with it's whole partitions .
the sim card status in the settings says Not Available for everything , and yes i can't make calls nor sms without the sim ,
but you still didn't answer my question : do you get this when you remove your sim ?
no one with a similar problem ??
I've seen it on lots of Samsung phones. It's simply a signal for emergency calls. You have to be able to make emergency calls with or without a Sim and that's telling you how much signal you have.
Seriously people this is pretty simple and no conspiracy.
You only get a circle with a line through if you have a sim card installed that is blocked from the network or the phone is stolen / blocked etc.

good to hear ,
what made me think it isn't ordinary thing is that the service center didn't know about it & thought it was a problem ,
thanks a lot .
This was done on last update Samsung gods thought we needed to know how much of a signal we had for emergency calls
Having the same problem with my samsung galaxy s6 SM-920F. showing bars on the signals even without sim. not connecting to network operator as well. showing Disconnected status in SIM status from About.
Tried updating the software even downgrading, factory reset and wiping cache but nothing worked.
Found this thread when looking for an answer to this question. In my case, it is a tablet that hasn't even got a sim option but still has the mobile network signal showing, even when airplane mode is switched on. Just worry it is eating some of my battery life. Any ideas?
I am also getting same problem.
There is no sim card inserted in my phone but still it shows the network bars.. Your And my problem is same.
There, an actual answer. Guess I should add it here since I wondered the same thing
a sim card has nothing to do with the transceiver system of the phone. its literally a "passkey" it is your authentication to USE that network. ie you can always SEE the network you just not allowed to "use it" without permission hence the simcard.

Hello guys, i have an xperia z3, when i insert the sim card its says "no service available" but when i insert the sims the cellphone recognize it! it reboot everytime i insert or remove the sim card, its really weird, i tried to do it by APN, but nothing, then i decided to download 2 apps that gives u sim card info. I dont know how to upload images here, but it shows the name of the operator, the sim serial number and says network state "In service" but Network type "unknown" and in the other app says service state "service powered off" , i would like to upload images but the page says i cant upload external links...could u please help with this? ty.
reset network settings worked for me
I know this thread is very old, but I've recently run into the same issue and found a solution. In the settings, there is an option for "Reset Network Settings". This will remove all your wifi networks and any downloaded access point settings, but fixed the issue for me. Hope this helps any future solution seekers!
