hi
there is a app that could help you
OpenSignal (free) in Google Play
https://play.google.com/store/apps/details?id=com.staircase3.opensignal
Another app
Network Signal Info - free too (the paid app It's to support the dev, no ads and more widgets)
https://play.google.com/store/apps/details?id=de.android.telnet
I did used when I had signal problems in my neighborhood ... the telecom companies always said ... It's your problem ... your device ... your software ...
just test It ...
PS. to eliminate doubts ... hardware or software ... flash a stock fw (from UK O2 > sammobile) ... (necessary login)

Have you used the correct CSC for your network .
jje

Ive tried many but im not to sure which one is right as the phone came a btu because it comd from phones4u. I can always try it if you know which one correct. One the plus side so far so good with the new sim even got a slightll signal boost but not on 3g but the area im in this weekend is supposed to be c**p for signal 3g wise 2g works flawless. True test will be when i go work which is when it tends to happen the most. If it happens again after a csc change I will just claim on my insurance as the antenna is a broken heap of **** I got a new s3 there and then for 50 excess. But rather not pay again lol hopefully cheaper to fix my self unless its hardware.

(I should have flashed JPKJ2 gb 2.3.5 firmware, but because its outdated, flashed the kl1 2.3.6 instead)
My problem is that i cannot access the 2g or 3g internet. I have the jKay mod which turns the signal icons to green. but they dont. they just come on (grey) but dont connect.
I called the operator many times to install the settings. but still no help.
If anyone in uae, can u confirm theres a gb 2.3.6 for uae?
any advice?
I recently bought a samsung Galaxy Y, and this had 2.3.6 xxkk(?) firmware with arabic support. Can any UAE user confirm that there is a 2.3.6 official update for galaxy s2?

Check your APNs to see if they changed or got wiped out?

Yep, they are still there.
I installed new one by calling the helpline. they told me to restart my phone afterwards. i did, but still cannot connect.
Is it possible that marketenabler app is causing the problem? i know that when you switch sim ids (from local to US etc) u cannot connect 3g.
but even if i try to connect with local sim id it does not connect
Man, just Google for your provider apn details for android. As far as I know 3g etc should work the same on all firmwares unless your phone is not the international version.
I have the i9100t which has a different modem. When I flash any rom I reflash just the modem and all is good again. But first make sure your apn is correct and you have selected it (should have the green dot beside it).

Hi all,
First time poster, long time follower!!
I'm hoping someone can help me here because i have a real headache with my galaxy s2. I live in Rep. of Ireland.
When i got it at Christmas everything was perfect. But two weeks later i suddenly lost my 3g. Phone works fine on 2g (except for the slow speed), but i contacted my carrier 3Ireland and they said everything is fine on their end. My APN is perfect, i've tried toggling airplane mode, entering codes, data package checks. You name it and i've tried it.
When i force my phone to select 3g it looses all signal and i have to restart my phone and quickly go back into settings to choose 2g or i will loose signal again.
This is the following on my phone.
Android version 2.3.5
Baseband version I9100XXKI4
Kernel Version [email protected] #2
Build number GINGERBREAD.XWKI8
I've being reading about modem/radios lately, is that just the baseband? Could that be my problem. I'm a noob at this kinda thing.I just want my 3g to come back.
All help is greatly appreciated. Look forward to hearing from you all.
Thanks.

sxi200 makes an excellent point. Make sure what your model is - GT-I9100, GT-I9100G, GT-I9100T - it WILL make a difference.

Because I've flashed an international firmware, when the phone boots up it shows i9100 and in settings / about phone it also shows i9100.
The only place it shows as an i9100T is on the sticker under the battery. So remove the battery and check just in case.
EDIT: you say you flashed an Indian firmware. Aren't Indian models the i9100G. Maybe you need to flash the international firmware if you indeed have an international model.

Well, i did go back and flash the jpkj2 2.3.5. and still no connection.
will try from an open place again later.
i have an issue with my internet connection too. i got an I9100(international version) and things were perfect till i switched to 4.0.3 and since then, my internet just refuses to connect although i have full signal strength and 3G or H displayed. but there is nothing going through.
it works again after i switch to airplane mode and back. i have no issues with wifi.
i have tried many modems and roms. i am currently using the KI4 rom and it still gives me issues.
please help.
update on situation
Hi guys,
just an update on my situation. Had the phone sent to Samsung twice for a check and bothe times it came back perfect with test sheets showing all was perfect. I decided to have another check done on the phone and it now says that the phone is blocked!! What the hell!. When i checked first weeks ago all was good and now it says it's blocked, but i'm getting 2g signal, surely i should be getting nothing if it's barred.
I have no idea who the origional service provider was of the phone, is there any way of finding out who the origional provider was or is there any way of removing this barring?
Thanks

[Q] Stock ROM forSGS III of Bouygues Telecom France

Need Stock ROM forSGS III of Bouygues Telecom France
Few months ago I bought an SGS III GT-i9300 with CSC of CHU running stock ICS 4.0.4 ROM (bouygues telecom). The phone was originally bought in France, and later on when I came back to my home country ie Pakistan, I got it unlocked so it could work on local carriers. The long of the short of the story is, last sunday I decided to update my SGS III to the leaked polish JB ROM I9300XXDLIB_I9300OXFDLI1_I9300XXDLIB_XEO. This resulted in loss of connectivity with my GSM network. Sadly, I made the cardinal mistake of not backing up the original ROM, in case I needed to go back. So now I am kind of stuck with a phone which at best is just like a small tablet ....
Can anyone please help me locate Stock ICS 4.0.4 ROM for the above CSC region? As so far I haven't been able to do that despite hours and hours of trying.
Also, can I install Stock ICS ROM for CSC PAK/WDC on it? If so, how can it be unlocked & made to work with it?
I hope that someone can help me in resolving this issue. Thank you.

Thanks alot JJE. Didn't knew about this checkfus tool, but it sure is one very handy util. I will let you know of the progress asap.
Regards.
Okay, I used CheckFus to locate the ROM, downloaded it, wiped/reset S3 before going ahead and installing the ROM. But unfortunately it didn't help. By the way CheckFus in Product Code field says 'Not Active'.
I was wondering whether I should get unlock code, will it help solve the issue?
In continuation of my previous post, here is an image from Galaxy S3 Sim Unlock.

That "Not Active" against the product code is probably the cause. Any help will be hugely appreciated. regards

[Q] No Network in Galaxy GT I9300 After Odin flash

Hi Everyone,
I know there are a few thread around with the same purpose, but nothing helped me. I even did ping few members who claimed to have known the problem, to my bad, they are busy to reply me. So i thought i would start a new thread explaining my problem.
I got a new Galaxy GT I9300 Before 3months in Singapore, The shop is famous for selling smuggled phones, so i am not sure to which country mine belongs to. There was no network initially, so the shopkeeper offered his help, He gave the mobile to a nearby service centre and got it ready,
I am not sure what he did, but d phone had CWM and Super User. I already own a Galaxy S2 and i have done a lot of flashing Custom MOD's, So i wanted my Galaxy S3 to be original for a while. So i tried to restore by flashing a official firmware, To my surprise the phone didnt have any network in it after the ODIN flash. I tried an INDIAN firmware, then Singapore.
I tried CWM (which i am not a pro) but couldn get back the network. I went back to the service centre and he told some files are corrupted since i flashed the phone with official firmware.
He again flashed it, now the network works, voila ! I couldn figure out and he wouldn tel me. ****ing $40 !!! The phone had CWM and SuperUser installed in it again.
The phone had the following information after wat ever he did.
IMEI - 3531*********99 it is same in d board and in the phone information.
MODEL NUMBER - GTI9300
ANDROID VERSION - 4.0.4
BASEBAND VERSION - I9300DXLE9
KERNEL VERSION - 3.0.15-611327-USER SE [email protected] -71 #1SMP PREEMPT TUE MAY 22 21:54:17KST 2012
BUILD NUMBER - IMM76D.I9300XXALEF
NETWORK - SINGTEL
SERVICE STATE - IN SERVICE
MOBILE NETWORK STATE - DISCONNECTED
MY PHONE NUMBER - UNKNOWN
ERI VERSION - N/A
IMEI SV - 01
SERIAL NUMBER - 000000000000
DEVICE STATUS - MODIFIED
Can anyone please infer on what the service guy had done. so that i can update my phone to JB. I am sick and bored of the same firmware for over 4 months and i wanna change it. But i dont want to get struck in the same issue. Please help and advance thanks !
I am afraid you had bad luck
1. You should NEVER pay for stuff that does not work (and is not with original firmware).
2. You should also read this - it is almost certainly the same story (in your case SN 00000000 should also give a strong clue things are not what they should):
http://forum.xda-developers.com/showpost.php?p=34226179
3. Since whoever f***ed those things the first time on your phone did not make an efs image-backup you can never return to factory state!
4. You are basically stuck with a phone where you will have to apply a patched modem after each ROM upgrade.
when you say patched modem what do you mean.?
Patched modem ???
When u say patched modem, can u explain tat ? Is it possible to create one by ourself ?

A patched modem apparently is modem code that does not check all the stuff in the efs partition (for instance when SN is 00..00) - I am currently using the one posted by ariza somewhere around. Patching one might be quite complex and for the moment I did not have the time to research that. The only problem that I see is that certain providers are said to be using very unusual modem code (since they have unusual settings in their own network) - and in that case you need to use a patched version of that specific modem version - but so far I have not seen that happening in a very repeatable way in posts from european networks.
The other problem is that when you install any full ROM (for instance 4.1.2) that will overwrite your modem - so you will have to re-install the old patched modem (so far ariza_v04.zip seems to work OK with 4.1.2 on my operator's network).
Serial no 000000...
Thousands of Thanks man, I have been facing the same problem from last few days after flashing cwm6 and UltraRom. hi can you please suggest me an modem for Samsung Galaxy s3 I9300 Indian version.

Bad signal

I got the SIII i9300 and I upgraded it recently to 4.1.2. I don't know if it's from the upgrade or from my new carrier but I got some horrible signal (including indoors). It will show H and full bars, but when I try to call out the bars drop, it goes from H ro G and even a lost signal. So I don't know if its a ROM issue (it was a rooted stock BTW) or the radio needs a update.
Any thoughts? The provider is Play in PL.

Maybe incorrect RIL?
Sent from my GT-I9300 using xda app-developers app
OK. Found a link here with a 4.1.2 PL unbranded RIL.
XXELKC
Android:4.1.2

How do I install it?

baseband:I9300DXELK1

Use Odin
OK.
Ill give that a try. It seems my ROM is a SG version :d'oh:
If it doesn't work I'll reflash my ROM with the PL unbranded which has the correct RIL.

Theres an app called getril where you can auto-match modem & RIL or just check if they are compatible if you dont have root.
I don't know where you live but I can recommend you to try out the XXELLA baseband / modem - simply the most battery and signal reception friendly baseband for the Samsung Galaxy S3. Do not forget downloading and installing correct RIL thru getril-app from Google Play for stable signal reception..

SIM card wont register on phone.

Hey all..
I had a weird thing happen to me today, my s3 GT-i9300 wont register the sim at all it all started when I flashed 4.3 from 4.0 today I've tried everything possible to get the sim to register. In all honesty, I've become discouraged and would be happy to just get back to stock rom... at least the network was working. lol
Originally I bought this s3 in HONG KONG, the baseband version that I flashed 4.3 is from Kazakhstan.. So I went over to http://samsung-updates.com/device/?id=GT-I9300 and found that TGY (Hong Kong) has 3 firmwares: I9300ZSUBNB1- 4.3- 26.02.2014 and I9300ZSEMK3- 4.1.2- 06.11.2013 and I9300ZSEMC1- 4.1.2- 11.03.2013
Question: Which one do I use? and what would be the steps in fixing this problem?
Heres my info:
IMEIs match on BOTH in status of phone and on the back of the phone
Im currently on 4.3 Android Version
Current Baseband version: I9300xxugna8 [Kazakhstan]
Cell phone carrier: Mobilicity (Which is owned by Rogers)
Thanks for all the patience and help in advance.
Cheers.
Nevermind gents, found the solution. ANDDDDDDD the best part is.. I can stick with the 4.3... [sarcastic YAY]
Solution thanks to the folks at AndroidVeterans
Maybe the ROM you used is not Stable 100% that's why u faced that problem. So the solution is to back to your stock ROM with the official baseband that it was installed before you upgrade. in my opinion if you flashed a stock ROM with the wrong baseband can make your device unsupportable to the network (even you flashed many ROMs the problem will still exists)

Don't panic bro ,international S3 had this problem on updating manually , not for custom roms only for stock 4.3
The only solution is z3x box , it can be only done using that box :good:
You have to only repair network from it
