[Q] Galaxy S GT-I9000 unable to connect to network

Hi everyone,
I am experiencing a quite strange problem with my samsung galaxy S GT-I9000, Gingerbread 2.3.6 JVU.
All of a sudden, it became unable to connect to network with my Three simcard.
It says emergency calls only, is able to research for networks but cannot register on them
The strange part is that the simcard is fully functionnal on other devices.
The really strange part is that my phone is able to connect to network with other simcards.
I found posts with people experiencing some similar problems and tried to use their solution but without success :
- flashed the ROM (3 or 4 times with different firmwares).
- Factory reset
- Backup / Repair the efs file using efs pro
- tested that my IMEI is fully readable
- Conversion to Buddhism
- verified the APN data
I was thinking that my IMEI might have been ban by error, but my phone should have not been abled to register on network with different sim cards ?
I think maybe there's something interesting, in the service mode, in the debug screen; in sim information I have :
SIM type : USIM
SIM State : Pb Init
SIM Reset : StartUp
Does anyone has ever encountered the same problem or have any suggestions ?
Thank you,

[Q] LG Nexus 5 fails to recognize celullar network

Hello,
I have a Nexus 5 phone that came with Kitkat a few months back. The phone worked without issues until I decided to update to Lollipop 5.0 (OTA update) at the end of November. Initially the phone started to have troubles to detect the network at certain times - typically "playing" with the settings "Preferred network type" by changing from 4G to 2G, restarting, letting the phone detect the network on 2G mode and change back to 3G or 4G would fix the problem. The issue became more and more frequent until a point where i can not change the "Preferred network type" from 4G to any other type (as if it is "glued" on that setting). At this point my phone does not recognize at all the cellular network but It does seem to recognize the SIM card since i need to enter the 4 digit code to unlock SIM and it displays the network name, just no service.
I've researched the internet and I've tried several things but nothing seems to fix it such as restart mobile, change to airplane mode and back, take out and re-insert SIM card, request new SIM card from operator. The APN settings seem to be OK.
I've noticed that a new 5.1 version just came out and although I was not fully familiar with the process i decided to give it a try (after reading several instructions) and update manually (using factory images posted) and see if that would fix it. The phone is now with version 5.1 and still can't recognize the cellular network - no service. Everything else works fine, including Wi-Fi.
Has anyone experienced such issue after OTA update? The only odd thing I can think of is that I did the initial OTA update to 5.0 in US while i was on travel from Europe, but I can't say if this would in some way contribute to the issue. The mobile is D821 model.
Since I was stuck and mobile is within warranty period, I have sent it to service repair. I would be interested to know ideas of what could be the issue cause.
Sorry for long message, any help would be very much appreciated.

getting signal with now sim card installed ?

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.

I've get Signal but Emergency calls Only

Hello, so recently I bought a second samsung galaxy s7 (G930FD made in indonesia) I'm livin indonesia too. So, I have some problems. When i got the phone it had android 6.0. Everything worked fine, the sim, ussd codes, 3G internet. But status Phone is Custom, i can't upgrade via OTA and i trying upgrade via Odin
After that, i`ve upgraded to android 7.0 via Odin. I downloaded an official android for verizon s7 number PDA G930FXXS2DRAB, Now, with android 7.0, I've signal and strength but emergency call only, i can`t call any USSD codes (for example *200# that is the code for checking my sim balance). It just shows that it calls the ussd code and then says that the number is incorrect. Also, i can`t connect to the internet. I tried to find the Acces Point Names, but they are nowhere (like this function was deleted).
Also, in my settings app, i have 2 unknown options. T roaming and Service provider Giga LTE, KT twophone service and whenether i enter them, my settings app just crashes and it wants to restart it.
Please help me!

Have you tried connecting using 2G only if you can get to a place that sets the network? I had similar on my S4 and if I used dialer codes to force 2G it would connect, allow calls and allow EDGE data. I never resolved the issue but the best I could find out was the EFS/modem was corrupted or incorrect so it can't communicate on 4g.
This also happened after a 6.0.1 to 7.1.2 upgrade though I'm not sure it's the same as I don't think the S4 supported Nougat officially. I gave up when I went to a local phone shop who were apparently an authorised Samsung service centre but didn't have the tools to repair/replace the EFS (or anything else so it seemed).

Hi!
The same thing happened to me, I couldn't send messages or call until I activated the automatic network mode, otherwise it wouldn't let me call.
I hope I have been helpful with this.

The same problem happened to me, i tried everything..
The only thing that fixed it is:
1. Insert a Sprint SIM card (in my case it came with the device when I baught it. I never had service from sprint and I lived overseas)
2. Select settings >> Network and Internet >> Network settings reset.
3. That is it!
Please note that this method only worked when I inserted Sprint Sim card, it did not work with my actual sim card..
After the settings were reset, I removed Sprint SIM, and inserted the other SIM, and it worked perfectly!

This worked once for me, then I had to remove my tray to insert an sd-card and didn't work anymore... network settings struggle to reset (will take 10-20s and then crash out) what could it be? I'm using a heicard and discussing the procedure in this thread: https://forum.xda-developers.com/t/unlocking-lg-g8-sprint-bad-esn.4092771/page-2
UPDATE: if you still get the "SIM not provisioned for voice" message, do a backup, then full restore of the phone, then repeat the above steps. You should now be able to make phone calls, but not connect to LTE. Download an app called "AddAPN" from the play store and manually save the Access Point Name for your carrier (yours will be different from mine, but I'll add it as reference, it's in italian, but you should get the gist, relevant steps are 10 through 14: https://www.helpforsmartphone.com/coopvoce/it/lg/g6/android-8-0/guides/22/Configurare-Internet-LG-G6)

with my sprint lg v50 and i can "Add APN" already.
i dont need an app

@en11gma Are you on android 9 or 10,and what is your security patch level?
Thanks.
