My GS2 was working fine up until this morning. I tried making a call and i get a message saying "Mobile network not available" The network bars are also grey and not turning blue.
Strangely my 3G connection is working fine. I can browse internet pages and use apps that require an internet connection.
Here are some things I tried
I manually tried to connect to the network and i get this "Unable to connect to this network at this time. Please try again later"
I tried my sim in another phone and its working fine. I tried a different sim and i get the same error message
I did a Google search the error I came up with a several people with the same problem. It seemed there IMEI number was changed to a fake one, but i don't have this problem. My IMEI is the same as the original.
any help would be appreciated

Mate, you can try to change modem. Should solve you problem
The are a few modems on here. I tried a few and managed to install only one the rest failed with an error. The one that flashed didn't fix the problem.
Any recommendations on which modem to use?
Also you can try cleaning your Dalvik Cache if you are not still successful doing that, try to factory reset but dont forget to back up your contacts..

I just tried the K14 Modem. I still have the same problem.
I tried a different rom but no joy.
I can see my network name in the settings menu but under service state its saying "Out of service"
The strange thing is my data connection is still working so Im sure my network hasn't barred the phone.
Delete you current network settings and remake them .
After that its a service centre .

i've got the same operator 2 times in my status bar so when i send sms it charges me like i've send 2, and also 2 are send :S i got latest miui rom
A reboot fixes it for some and needs a full wipe for some..

it founds my operator 2 times i tried connecting to each one... when i connect to the first i have the same problem, but when i connect to the second one it says emergency calls only
I have tried with different roms and different modems and my phone always does the same thing: When it should connect to mobile data network, it just doesn't.... i have to reboot the phone for it to get data connectivity....
The APN configuration seems to be ok, they are the default ones of my carrier....
This has been happening when i was using MIUI and still happens with CM9..... its weird because no matter which modem i install, i have the same issue and the same way to solve it..... any ideas?

Maybe you have already checked it:
There is an option in settings menu for mobile data connections, which you have to enable.
If that is enabled, but still not connecting, try to wipe cache and Dalvik cache in recovery.
Good luck !

Maybe you need to contact you service provider and reinstall APN settings on you phone?
I thought the default ones were the good ones..... i will try phoning them and see if its an APN configuration issue... thanks!
This can't be.... its still not working after i entered the APN info by hand.....
I don't know what else to try...

Hi,
I'm facing this major problem with my handset.
When I insert a SIM card to my mobile, it registers with the network (VODAFONE IN) with signal strength of 12asu and then gradually decreases to 5asu and then 1asu when my phone shows no signal afterwards. The carrier is shown as Unknown and service as out of service.
If I put the same SIM in another phone, it works. So no problem with the SIM or Network.
I have tried the following:
1) Flashed various modems
2) Flashed various ROMS (CM9, CM10, Official Stock)
3) Did complete WIPE. Factory Reset, Clear cache, Clear Dalvik cache, Format /system
4) I also restored by efs to a backup I had of my efs(taken when I first got the phone in 2011).
5) Also used Repair Galaxy S2 app which basically fixes RW permissions of the EFS folder.
6) Also used EFS Pro to repair my .nav files
7) Also used GetRIL tool to check if the drivers are matching.
Even after doing everything, the problem is same. When I first insert the sim card, it gets signal for around 5 minutes and then suddenly it goes to 1asu with no signal forever. I also kept my phone as it is for one whole day, but nothing: my phone is unreachable and there's no signal.
I had never dropped my phone and possibility of any physical damage to the receiver is very low.
The only reason I can see is this:
I was on DilDroid ICS and everything was fine until one day, I went to Recovery and fixed permissions. (Btw, DilDroid ICS used Siyah kernal)
And I think that was the last thing I did after which my phone couldn't receive signals.
I think some files have been corrupted and even after factory reset etc. it remains and the next time I flash another ROM, the files are still there.
Can someone tell me a way to completely clean my galaxy s2 and then start off by flashing a new ROM.
Or any other solution. Kindly help.

do a full wipe and install another rom and see
1) Wipe data/Factory reset
2) go to 'mounts and storage' and wipe data and system there.
3)wipe Cache partition as well as Dalvik in advance.
then install the rom zip file
and again do all wipes except system and then check for issue's
ps- before that try with a different netwrk sim on the phone and see if the issue persists or not

Hi Sun90,
I've tried flashing different ROM after complete wipe. I also wiped system. But never wiped data. Doing it now.

update:
I tried your approach, but still facing the same problem. Please help.
Hello everyone.
I got exactly the same problem. I had my I9100 for over a year. I flashed lots of roms. Now i got this problem. I cannot connect to the service of my carrier. I got realy bad connection or no connection at all. The sim works on different Galaxys and its not a problem with the apn and or my IMEI. Evereything is ok there.
what have I done so far:
flashed several roms
flashed several modems
went back to original rom
several whipes
Now I have a nice MP3 player with some WIFI at home
What im thinkin about could be the problem but I dont know how to fix it:
I think i got a wrong CSC and there is something rotten with my partitions...

yes i tried another networks's sim as well. sim was recognised. sim-pin ok. but no service/connection. on manual carrier choice the galaxy said something like connected to service. but there is no internet and if i try to make a call there is the "no service" popup again.
i dont think its a problem with the HW because sometimes i see the different carriers. i just cannot connect to them!
as I said before: I think its a SW problem around CSC and/or somethin is ****ed up with my phones partitions...

That's true. If I sometime connect to my network, I can quickly make a call & for the duration of the call, it remains okay. Pretty strange. I can goto flight mode and then back and sometimes I get the signals back for around 2-3 minutes before again going to no signal.
@Aton88, Were you by any chance on Siyah kernal or DilDroid ROM or went outside India? Just asking. Trying to find a pattern here.

yeh sure, give it a try
and by the way creating more threads for the same issue doesn't bring about any goodthing to u for sure, hence stick to the rules of XDA, rather than doing this and getting Infracted by the mods for the same

Thanks for the advice. I shall make sure I don't create duplicate threads. Btw, I even checked if my phone is locked but it's not. Everything is OFF.
I even checked the validity of my IMEI and it seems to be valid.
I'm really running out of ideas to check what's wrong.
I tried a different provider's SIM and even that doesn't work.
Can someone tell me how to do a complete clean install.
Are these steps complete or any steps are missing:
1. Factory Reset
2. Clear cache
3. Clear Dalvik Cache
4. Clear Battery stats
5. Wipe /system
6. Wipe /data
Then Goto Odin: Flash the official Stock Firmware for India.
Am i missing anything? I want a complete WIPE, so that no previous corrupted files are present. Please help.

u can give it a try with those steps but no4 is not necessary
i have a similar problem.....in the about section my network is displayed correctly but under "service state" it says out of service... BUT the internet works fine....when i try to make a call it says "not registered on network" ...the sim works fine in other phones.....the IMEI is also fine.
heres what i have tried :
1) change sim card
2) change roms
3) go back to stock GB that phone came with
4)wipes (all)
now i think i messed up something with the ril cause i changed it and i think thats where the problem started.
i got backups of the efs but i dont wana go there unless absolutely sure that the problem is there.
(is there a way to i dont know like check the integrity of tue efs or something)
I'm having a similar problem with my s2
Sent from my X10i using xda premium
if someon could plz check this for me.
i went into the service mode menu *#197328640#..then option 2 which is version info ...then option 1 which is SW version....then option 1 which is READ IMEI ...now when i selected that it said IMEI :NOT SUPPORTED
i dont know if thats normal...so if someone could please try this and let me know..i would be extremely thankful
ok so i did a lil experiment :
i purposely messed up my IMEI to that generic one with lots of zeros ...and suprisingly the calling function is back and i can use the phone normally except ofcourse the fact that the IMEI is messed....
Then i restored to get my own IMEI ...and together with my IMEI ..the problem came back too....
(oh and once again if someone could plz confirm the thing i asked about in previous post thanks)
My imei says not supported "/

Network signal issues
Have you tried checking network operators and manually searching and selecting the Network provider?
also have you tried flashing a different radio ?

Hay everyone .
I recently flashed salmanrom v 4.2 and everything went fine until I was unable to use network data my carrier gives me. However, I could still connect to wifi.
I can still send messages and calls but I can't connect to the internet because I'm unable to to use my network data. I tested the the sim on another phone and everything worked perfectly even the network data.
I'm really frustrated someone help me please
Known issue with that ROM?
If not, flash a new modem.
If you are getting your network you should be able to use data tho.

Check and make sure your APNs are set properly for your carrier on the phone you do not get mobile data on.

That is excessive if fixing APNs might solve his problem. Plus, re-flashing the same ROM may not auto populate his APNs anyways.
Good day guys.
I have a problem that I think is very common, however I haven't found a solution yet. I recently update my S6 edge (925I - latam) via odin to Nougat, everything was cool but I can't do or receive both calls or sms. I have cellular signal, however there is not registered with the network carrier.
I already flash modem.bin from older firmwares and do not work. Sometimes I loose cellular connection or stay the same, with signal but not registered. I tried other possible solutions like airplane mode and reboot, flashing roms, connect only via 2G or 3G, nothing have worked. My sim is not corrupted and the imei is just fine, without report or related.
I hope you can help me. Thank you very much.

Same issue for me.
Tried:
OTA update
Odin update - installing new stock firmware (with different software version)
Factory reset
Installing TWRP + LinageOS beta
Replacing the sim slot in a service
Nothing worked. Anybody?
Look in settings > status
Do you guys have an IMEI?
This happend to me 2-3 times last 30 days... sometimes I have signal but not registred on network, sometimes there's even no signal, etc...
I also tried several things to resolve the problem...flashing modem, reset dialer, changing network mode, enabling airpalne mode, another SIM card, etc... For the 1st time, flashing modem helped... but 2 days ago when this happened again flashing modem did not help...then I tried changing network mode and I got signal again... last night it also lost signal and today I changed network mode to 4g/3g/2g auto and it got signal again, then switched back to 2g and it's fine till now...
Hope this will not repeat....if does, coulb be very annoying thing...

Bro, download some older firmware from the one you have from sammobile and exctract it...there you'll find modem.bin
At last, I couldn't fix my s6...so I sold it...then the guy who bought it needed to write some chip to motherboard and he got it working again...
