[Q] Voice Calls - Mobile Network Not Available - Galaxy S II Q&A, Help & Troubleshooting

Hello All,
I'm facing a problem on my S2.
Since yesterday my phone stopped receiving and making calls.
No update or change has been made.
The internet was not also working, but i checked the APN configuration and was some wrong configuration and corrected, so internet is now working but no calls at all.
I really don't know what is the problem, the IMEI is correct. So i dont believe that EFS has been corrupted.
Need a help from you guys.
Android Version - 2.3.4 Stock Rom
Build number: GINGERBREAD.UHKG7

Where did you get the phone from? Make sure the imei is not blocked.

I got your point, but the internet is working, if the IMEI is blocked internet should not be working as well right?
I got another sim card from another operator and the same problem occurs.
IF the IMEI is blocked is just for one provider, right?

Dial *#06#
Does it show the correct IMEI # or is it unknown?

The imei can be blocked for country or few for example EU and for any provider no mater which sim but internet should not work as well

Guys please anyone has any clue on how to solve this?

Is there an indicator where your signal bars are, have you tried the sim in another phone

Full signal....3G is working..can access internet
Right now SIM is on another phone working properly.
already re-flashed....nothing
I thought that could be a blocked IMEI but internet is working so...IMEI isnt blocked.

Hey!
If its not locked, then I dont get why its not working. Its not matter what SIM(working one) you use, it must work.
Dose you sure, that it not locked?(I seen you answer, but strange why its not working then).
Maybe you need to do some contract with WIND?
CHEERS!
sometimes when i switch airplay mode on/off for a couple of times it recognizes the network, it has signal, I can make calls and recive but only for a couple of minutes or untill next reboot.with my sim from my country works perfectly.at firs i tought that i bought a stolen one and imei is blocked from italian carriers becouse none works.i tried all of them exept 3.
i was searching for /efs folder but i cant find it.maybe is becouse of this?i have a valid imei

hello,
did you try to flash a stock rom, because i had the same problem and after flashing a stock rom, the problem was fixed.

Not registered on network, again

This thread is outdated and not related to the new problem with EFS coruption. Solutions proposed here wont help you if you lost your network after downgrading a ROM from MF6 to earlier.
Ok it's not the first thread about this but no one seems to have an answer. I'm trying again.
I flashed a custom ROM on a friend's phone i9300. After the flash the phone keep saying "Not registered on network". I tried everything I know.
I changed modem
I changed ROM (3X) (with full wipe)
I returned to stock
I installed GetRil (changed the baseband)
I installed Galaxsim (phone already unlock)
when I try to set the APN I get a message "registered on network" but when I do a phone call I got "Not registered on network"
Is there anyone who knows any way to solve this problem?
New sim? What all works?

everything works fine on the phone except the call/ 3g. She came with her own Sim card but she left me the phone and I'm using my own Sim card and same result.
Now I see that the IMEI SV is 01, My phone Number is UNKNOWN( is it normal?)

Get a new sim from your carrier. Either your sim tray is broken or your sim card is. Sim card is cheap/free to replace so try that first.

sounds like (both of you) your EFS folder is corrupt - the only way i've read of repairing it is to have a back up. service center for repair is the only option AFAIK.
The IMEISV means nothing, don't even worry about it. Know what you're talking about before you blurt out crap.

Usual suspects .
Sim you tried another .
Sim carrier unusual to be damaged .
IMEI wrong .
No phone number details standard with many roms .
Network details not entered or incorrect or wrong CSC .
Wrong modem unlikely .
Best to restore phone to original firmware .

First I restored the phone with the nandroid backup I made just before flashing. (still not register on network)
Then I restored the phone to stock Samsung with Odin (still not register on network)
The IMEI is still there(most thread I read with this problem people lost their IMEI)
The phone can connect to the network because it can retreive the time from the network.
If I make a network operator search it finds China Unicom(This is my sim card) and when I choose it it says "register on the network" but as soon as I try to call, I get the "not register on network" again.
I thought the IMEI might be block as it might be a stolen phone but I made a search on two IMEI database and it says CLEAR.
I flashed 3 Asian modems( I used to have a S3 I know the XXELJ2 was working with my sim card) and same result.
Have you tried flashing a different modem to your device and reporting the problem to your provider.
May sound obvious but the provider's logs may clearly show what is wrong and they can report it back to you.

anyway, tried this metod too now, and still the same ~
Hey guys, had a very similar problem to kremata (everything in EFS folder seemingly ok (IMEI and S/N were fine)), and for me it got fixed by applying Azira's Patch ( http://forum.xda-developers.com/showthread.php?t=1918601 ).
However this solution only works by rooting and if you try to return it to stock it will reverse to being a 500$ PDA sadly.
In any case, the phone is now fully functional (calling/SMS/mobile data).
hey
i can fix ur problem

Unable to Register On network

Hi this is starting to really bug me now Im unable to register on a network I get signal bars but only get emergency calls only tried dfferent sim cards and reverted back to latest official stock to no avail any suggestions please
As per multiple identical posts .
First is your IMEI correct
Are your mobile network settings correct
sim card correct and tested
correct modem and csc.
jje
Check your IMEI number. Sometimes, when we flash custom ROM, the phone looses its IMEI number. If it's true, you must use an EFS backup to restore it.
Second solution : your mobile phone was blacklisted (if it was considered as stollen).
Network
Hi thanks for the reply I have been searching I've checked my imei in status and it matches details under battery compartment i'm still paying for the phone (pay weekly) so no reason it would be blacklisted ok just tried another different sim card on Vodafone official s3 stock rom and it registered hmmm im on talktalk which uses voda I know this sim works but i'll get them to send me a new one thanks for your time guys

S6 edge g925I not registered on network

Hi all,
I have a s6 edge g925I model which I bought recently. One day my phone stopped receiving signals randomly and gave me not registered on network error. After several failed tries I eventually had to get it rooted in order to fix the network error. But rooting had other issues with it such as phone hanging, default apps not working etc. so I unrooted my phone using smart switch software recovery. But now after unrooting my phone again gives me 'not registered on network' error. The imei is working and I have tried many different ways to fix the error including flashing new firmware through Odin, removing sim and plugging again, viping cache etc. but nothing works. Please help!!
P.S everything else in working perfectly fine.
maybe....imei issue...
I have the same issue, but the imei is not the problem, the imei works fine.
I have the same issue,The imei code is the same printed on the cover,so i don't think it is not the problem
Did any one find a solution elmisaklk?

*Question
By any chance do you have a back up of a pervious firmware that you coukd get the EFS and modem data out of? If not check your sim card out and remove the possibility that it died or malfunctioned in some way. Also check your APN settings in network and try turning on roaming after youve checked its not your som causimg problems
Anyone have solution for Not Registered on Network.
My phone is G925i
Sent from my SM-G935F using XDA-Developers mobile app
Hi There,
I have the same problem but I did not root my Galaxy. It happened right after the official Samsung MM OTA (G925F).
Do you have any suggestions to fix this problem?
At last I will go in a Samsung center to make it work but if I can manage to fix it without loosing the warranty would be better.
Thanks I'm advance!
Same Issue
Hi,
I have the S6 Edge G925I with the same issue. Phone was brought from Bextec for use in Australia, phone seemed to be linked to Indonesia, they asked for phone to be returned, when sent back to me, they have rooted the phone. Worked for a while but have now got the same error again. Rather than send it back to them is there any help for this issue??
Think a few people are having this issue, i get it if I switch over to anything thats not a 2g network, if i set it to 2g only it works fine and no dreaded "emergency calls only" status, might help someone maybe if you are set to auto on your networks try manual mode and 2g only networks, I am still looking for a solution to mine with the 3/4g working briefly and then it just dropping to "emergency calls only" after a short while.

My S3 can't be registered on network?

Hello!
My phone doesn't has a Serial Number which is lost but i have IMEI so to prepair that i flashed the original frimware from Samsung from Kies by doing "Frimware upgrade and instalization" so Kies demanded the serial number and i put it that's how i resolved this issue and now i have the serial number and IMEI but the problem is that when making calls the phone says "Not Registered On Network" this problem occured to me when i wasn't having the SN but now how it could happen and i have the SN ? i tried to go to settings and selecting the network that should i connect to but nothing changed. I think that Cert File or the EFS partition touched? Please help me i'm really in a big problem :crying:
really?
there's no one can help us with this damn "Not Registered On Network" "No SIM" and this changed serial numbers?!
there are many sgs3 with these problem,
somebody help plz
we tried every modems, roms, stock roms, with odin and different recoveries,
best question is, how we can correct this changed serial number?
and yes, there is no samsung service in my area
Most likely the device is blacklisted. You don't just "lose" a serial number like a coin falls through a hole in a pocket..
Beamed in by telepathy.
The IMEI is the serial number.
Also, network registration errors can be one or more of being the SIM card, blacklisted IMEI and/or SIM card slot being bad itself.
Good luck!
