Yes i check the APN and all is OK!when i have turned on 3g i have signal only when i turn off 3g i lost signal
Could be that your area signal isnt that great on 2G network when 3G is off.. try another modem
hello i had issues last week i lost data connection i flashed all different roms trying to fix it ,i think its sorted now i flashed XXJVU stock rom then darky 10.2 re then i flashed cm9 then darky v11 then cm10 then thinkbridge 4.2.2 working well so far if its just your signal try 10. 2 re first
the best reason why it happen because the ROM or FIRMWARE that you installed in your samsung galaxy s is not compatible some firmware and roms are only allowed in a specific country because it contains MODEM that makes your cellphone to have a signal on what country you are in OR the Samsung Galaxy S that you have is only for certain country only like my Samsung Galaxy S SC-02B which is NTTDocomo which has 2.2 froyo firmware when i upgrade it to higher firmware such like jellybean or icecream it successfully upgraded but you cant use the cellphone 100% since the signal will lost because your IMEI is fake or your IMEI is none. check your back of your samsung to check the right IMEI.
SOLUTION:
downgrade your phone back to its original firmware and rom make sure it is the original!
and you will see it will back to its default settings your signal is back so as your IMEI
I am using Hong Kong Modem and I am in the UK with Full Signal and better performance
All Modems will give a signal ..but depends on area that you are in
Flash 2.3.6. Then Root it ...this will put all files back to the way they where..
In your APN settings scroll down to the Authentication Type and make it PAP if its Default for both ..reboot phone if that helps

Ok I took the plunge and installed :
Update Samsung Galaxy S GT I9000 to Stable Gingerbread XXJVK 2.3.3
and also re-rooted my phone.
No I only have a G symbol as to before I was on 2.2 Froyo with no issues.
Im currently on Orange (Contract) in the UK with the same APN settings as before.
Any help on this please let me know.
Thanks

Use Packet Data and Data Roaming are both ticked, does this make a difference?
Also Network mode is on : GSM/WCDMA (Auto Mode)
did your modem change when you changed ROM ?
Just find out what modem you should have and re-flash that... also check your APN settings... also do a search in the forums for this exact problem... it is posted like twice a day.. good luck
After updating my phone to the latest OS (Jelly Bean 4.2.2), everything was fine, but then all of a sudden I couldn't access the internet. I have tried several different APN settings and even flashed several other roms. I contacted my service provider (giffgaff) but they said there may be something wrong with my phone. I can send and receive calls and texts but just can't access the internet. I downloaded an app of Google Play which showed that my 'Data Activity' was either 'no activity or 'upload activity', however it still said that I was connected to my data. Can anyone offer any help or advice?
same happened to me i flashed darkyrom 10.2 re it seemed to work until i tried to connect to google play and i lost data and network changed from 3 to orange its doin my head in gona try a stock rom see if that helps if not it may be the sim card wife wouldnt let me try hers incase i wrecked hers also hahaha will let you know
I think that if u reflash it by 2.3.6 JVU firmweare will solve ur probléme and then u can update to 4.2.2. Good luck

You just need to put in the APN information for your network manually in settings.

Try to switch airplane mode on and off, then check the APN's and maybe you need to add your APN but that depends on your provider. This always works for me.

hi,
i upgraded my phone to 4.2 jelly bean slim rom . calling and other things were fine . but from tommorrow i am facing this problem.
in settings=>about phone=>status it's showing my network name and signal strength-64dBm 25 asu . my network is not 3g or 4g .
but my signals are white ( no signals but sim present and detectable) cant call . whenever i try it says "mobile network not available".
after this i checked my sim in other phone . it is working fine.
i put sim from some other network in my sgs but same problem
i flashed the same rom to fix it but no good
i flashed back my ics rom , no good
i did factory reset , but problem is still
i am using this phone for past 2 years and this problem never occoured.
PLEASE HELP ME .
there is some problem with the 4.2 rom or whatever, but you easily fix the calling part by installing another modem.
in my case I can't get the sms to get working, tried 3 modems already.. everything else is super fine.
I had a similar problem where I had no reception! Easy fix though
1. Find online your specific carrier ROM for the phone, (eg. AT&T SGS1 ROM) and flash it, firmware can be what ever (gingerbread, eclair, ICS)
2. Flash your carrier ROM, you may not pass boot screen but that's alright because the carrier ROM still embeds all carrier info.
3 Now re flash your jb ROM and enjoy
Hopefully this helped you out

See how your IMEI is now something like 00499....? The phone's generated a fake IMEI (which allows you to use the telephony functions such as data, SMS etc) because its lost the real one.
1.) Go back to a stock 2.3.6 rom using Odin. Your IMEI should be back to what it was, but check it just to make sure. However if you're able to send texts/make calls/use data again, your IMEI's been restored.
2.) Root it again.
3.) Flash in CM9 first (do the standard wipe data/cache/Dalvik). Let CM9 boot. To upgrade to Jelly Bean from Gingerbread, you need to flash in ICS (CM9) first to preserve the IMEI. Once CM9 has booted (you don't need to stay on it for too long), if you see that you're getting signal, you're all goods. But check your IMEI just in case you want to be sure it worked.
4.) Back into recovery. Wipe combo (data/cache/Dalvik) again just in case. Install Slim Bean from there.
5.) Once it boots, you should be getting signal as usual. Once again though, if you really want to make sure, check your IMEI.

Long time lurker, first time poster.
Long story short, a friend gave me an I9305, however, I can't connect to a supported 3G network.
He had toyed around with the device (rooted, installed CM11), then reverted unrooted and reverted to stock firmware. When I got the device, I rooted it with Framaroot, flashed CWM 6.0.4.5, then flashed CM11 and Boeffla kernel. My SIM card was quite old and my carrier told that it doesn't support 3G, so I filed up for a new one. Ok, I got it, however..I'm yet again stuck on EDGE!!!
Tried reflashing CM11, CWM, flashed almost every radio baseband modem from here http://forum.xda-developers.com/showthread.php?t=2010116 to no avail. My IMEI is intact, as well as my Serial Number.
Yes, I read all threads, I tried going to Settings>Wireless&networks> More > Mobile Netwroks >Preffered Network type and checked all options. When I select 3G only, the icon goes to "H", but i can't access the web. After 10-20 seconds, the H icon dissappears and I'm forced to reboot the phone to regain my EDGE data.
At the moment, I'm running the latest Omni ROM nightly. My operator supports all 3G and LTE bands, and I got the correct APNs.
Should I flash a stock ROM and check if this does the job?
I'll greatly appreciate any help, because I'm stuck.
Wipe phone factory reset flash stock rom with modem and csc for your network.

I can't check my csc code - whenever i type a code in the dialer I get "connection timed out or invalid mmi code". The only ones that work are *#06# and *#*#4636#*#*...
Ok, so I'm running a stock 4.3 rom and STILL have no 3G....tried everything.
Anyone, help?
Maybe if you can try to downgrade to a firmware 4.1.2 via Mobile Odin and then try and access the service mode menu. From there you may be able to enable the 3G/LTE DRX (Radio) which seems to remain a permanent change in the phone once you upgrade again to 4.3.
Can somebody help me with this 4g problem?
This is what i did:
1.flashed custom ROM (worked like a charm,i did nandroid backup)
2.flashed other custom ROM (didnt like it so I restored the first one from nandroid)
3.everything went well except no imei and no baseband
4.reverted back to stock rom with odin
5.and here is the problem,no 4g signal at all. 3g/2g works fine.
If I post my build.prop can somebody tell me whats wrong?
I have tried to put my sim card in other phone and it works but not in my phone.
Did you enable 4G in Settings?
Sent from my GT-I9305 using XDA Free mobile app
Yes, I did...network mode is set to LTE
Is there a test that I can use to test is it a software or hardware issue?
Maybe an issue of Stock rom you flashed using odin.. Which one exactly have yoi flashed? What modem you have now? And finally, is your S3 i9305 or some i9305T variant?
Check this out:
Typ *#*#4636#*#* and goto Netinformation, then you will find a special-setup for the 2G 3G & 4G.
Sorry about my english. Cause i am german.

Thanks for your replies,I flashed stock german 4.4.4 from sammobile.It worked very good about 2 months.
I think that modem is xxufoa1 and version of phone is i9305 lte international.
If somebody could help me with this issue,I would appreciate that.But no hurries,I got new playmate S6 edge...
try doing a complete wipe of data and cache, then flash stock rom again to see if problem persists
I have tried many times but no help...
Hey, try flashing the parambin.zip file (look for it on google related to s3 lte, you'll find it easily). Another thing to try is just wait with the phone turned on with a valid SIM. I found out that sometimes it delayed a lot to get signal, specially when changing SIM carriers on another country. After a while waiting it finally succeeded (probably unrelated but I also saw on the catlog entries about upgrading the sahara file of the qualcomm chip -the modem-).
