[HELP] No Mobile Data - Galaxy S III Q&A, Help & Troubleshooting

Background: One month ago I rooted and flashed a custom ROM for the first time, I had no problem.
After flashing a few different ROMs, I noticed that my mobile data was acting weird. I could browse the internet and access most internet required apps, but I couldn't download from the play store, watch youtube videos, or get messages from whatsapp messenger.
Problem Today: I just flashed a ROM that I like but now I have NO mobile data at all. I have full bars and my notification bar shows H+ or 3G but data just doesn't work. In the Browser I get this error: "authentication via the proxy server was unsuccessful".
I restored a nandroid backup of stock Touchwiz and data was working again. So I just did a re-flash of the custom ROM and data still doesn't work!
Notes:
- Notification shows data is connected but I can't access the internet.
- Did a restore to stock and data works, re-flashed a custom ROM and data doesn't work.
- Airplane mode isn't on.
- There is no mobile data limit.
- There is nothing in APN settings, there also wasn't anything in stock Touchwiz (but data worked).
- I flashed different modems and they don't work.
- I have tried some APN apps in the play store but they don't work.
- I am on UltimaROM v7.1 // Siyah kernel 1.8.5 // Android 4.1.2
- Wi-fi works.
Please help.

I ended up fixing the problem. So for those of you who might have a similar issue: the problem was with my APN settings. I just had to properly configure it and disable the proxy.

Check your ROM's forum or your kernel's.Maybe it is a common bug and you only have to wait until they fix it.

Auto-download MMS on CM9

I'm running the latest CM9 beta along with the APN Fix.
I'm able to send mms messages fine, but whenever I receive one (like an image text), it prompts me to download the image instead of doing it automatically. Furthermore, when I try to download the image in the stock messaging app, it doesn't work. I then installed GO SMS, which does allow me to download the image (most of the time), but I'm still prompted to download it instead of it downloading automatically. This happens on both wifi and 3G.
What I've tried (with reboots after changing settings):
I've double and triple checked the APN settings and have even restored my APNs to default and then re-entered them.
I've also tried playing with different APN settings than whats in the fix.
I've toggled the auto-retrieve setting in the stock messaging app on and off.
I tried installing the black-themed mms app.
I've cleared app data on the stock messaging app and GO SMS
I've attempted to fix permissions, wipe dalvik, and wipe cache
I checked the mms size limits inside GO SMS settings
All of the above was unsuccessful. Each mms I receive still prompts me to download the image. When I click download it doesn't always work in GO SMS and doesn't work at all in the stock messaging app.
At this point, I think I'm going to wait until Joker releases a new build and see if that magically fixes it. If not, I'll probably have to wipe and do a clean install. I did a wipe between the last alpha and first beta build but have just been wiping dalvik/cache between beta builds.
Anyone have any other ideas / suggestions?
Thanks!
Try just using the first APN and deleting the other 2. That's all I've done and I can send and receive mms just fine using the stock app.

Thanks for the response... Just tried deleting the 'Production' and 'Internet' APNs and only leaving the CDMA one (the first one) and then rebooting. I'm still able to send mms but again when I receive one, it prompts me to download instead of just displaying the image automatically in the messaging app.
I feel like it has to be either a problem connecting / downloading from the mms service or there's just some setting somewhere that's causing it to prompt me to download before retrieving.
I also tried setting the APN Type to 'MMS' instead of 'mms', which allows me to click a little blue dot next to the APN... tho I'm not sure what that does (makes it the default?). However, when I did that, I lost the ability to send MMS, so I set it back to 'mms'.
I wasn't able to fix this issue without doing a clean install (wipe / etc). I ended up flashing the latest CM9 build (3.1) on top of the 0.2 build and the issue persisted. I then did a clean install of 3.1 and the issue is resolved. Images received via mms now automatically appear in my messaging app without prompting me to download manually.

Hi, would like to know if anyone else is having any trouble downloading apps from play store?
Mainly from Australia. I have stock XWLP8 XSA 4.0.3 that's in virgin mobile. It worked one day, the next, just stopped. It's not virgin mobile as another phone on virgin downloads fine on 3g. I also wiped everything, factory reset, wiped phone, re flashed phone, and nothing.
Any help would be great. Also, all other internet works, browser, tapatalk, you can even browse for apps inn google play, just cannot download anything

What's the error that you get when you attempt to download an app? Or does it just not download, no error whatsoever?

Are you using the same rom file to reflash or have you tried to redownload the rom? If you haven't redownloaded it, give that a try and reflash, your original file may be corrupt thus not allowing you to access google. If you re-DL and still have the same issue, try an older version of the rom or a different one to troubleshoot your problem. If you have the same issue with an older version or a different rom you know its not an issue with the rom but rather your phone.
I did not install this rom it's an update by samsung it's the official JB update

:good::good::good: I have solution for our problem Just : If you have freedom, you don't need to delete it to fix your phone,you should have a rooted phone obviously, simply download or go into file manager and go to etc/ there should be a file in there called Hosts. Delete that.
Google is now work fine , wifi icon is BLUE :angel::good::good::good:
Hi guys, I have discovered a solution
but you must have root
download root explorer
1.go to system folder
2.go to etc folder
search for hosts file, open it and delete all things related to google.
:laugh:
ok its and old thread, but maybe someone find this useful:
Enable automatic time in settings, thats all.
Any news?
I traded my HTC One to a guy and he is having this same problem. Can get cellular and data, but can't connect to google. Does this Hosts file thing work?
awesome!

Have you tried checking the APN settings?
I have an issue where i flash my phone with SlimROM and then Chrome and Whatsapp is not working on data. Then I realize that the ROM auto select the wrong APN settings. I entered the right APN settings and I have no issue with getting data.
Also check if all the apps are receiving data via wifi first.

Wifi works. I'm wrighting from my phone now. The settings where wrong but changing them is the first thing i tried but i didn't work.
I never had thisproblem before even when i flashed custom roms. It feels like it doesn't activate the net even if it says it does.
Got it. I had the settings for gprs and i needed the ones for broadband.
Hi everyone,
Thanks for your comment. It turns out the ROM was selecting the wrong APN by default. I switch the APN and updated the settings. Now it works like a charm

WhatsApp not working on 3G but working on Wi-Fi

I'm unable to use WhatsApp on 3G, but it works fine on Wi-Fi.
So far, I've tried:
1) Restore to factory default, flashing a new ROM, resetting APN, re-installing WhatsApp, rebooting, re-insert SIM Card
2) Using my SIM Card on my other phone (Note 2) and it works fine, but not on my S3.
3) Calling my service provider -- they said the fault's not with them.
I'm on CM 10.2 stable. Any help would be appreciated, thanks!

I found this thread which suggests using another APN (may have to check with the service provider).
The apps you mentioned are all messaging/IM apps. Maybe your network is blocking them on data? This is more common than you might think.
