Okay so here's what's happened.
My phone is the LG-925g from Rogers, and it's unlocked to work with Koodo. It WAS working just fine.
Sometime around my update to V20c (I don't know exactly when, so I can't say forsure it's the update) data stopped working properly on HSPA. It didn't entirely stop working, just sustained connections.
Let me explain.
On WIFI EVERYTHING works.
On 3G I can browse, check e-mails etc... but I can't download anything. Market I can browse, but not download. Youtube works in the browser, but not the youtube app. Shazam doesn't work. Facebook updates work in the browser, but not the Social+ widget. Weather updates fail.
I can browse and check e-mail and that's about it.
so data IS working, just not properly.
Here's what I've tried....
-Formatting NV partition
-Formatting Cache Partition
-Formatting internal SD Card
-Complete Phone Reset
-Took my phone to a Rogers store, hooked it up to the rogers cell network on a store-sim and it worked great
-Took my sim card to a koodo store, stuck it in a demo android phone, worked great.
- Factory Reset of phone
- (phone was not rooted at time of problem) rooted to install and use networking tools
-went into hidden menu 3845#*925#
-went into Other Hidden Menu: *#*#4636#*#*
-ran every test in hidden menu and looked for settings that may affect this
-Installed APN Remover to remove all APN's except Koodo
-Verified (with a koodo rep) every APN setting and even tried removing some or messing around with them
I'm about to downgrade and re-upgrade my phone to see if that works. Any chance that may fix it? any other possible solutions? I'll even take crazy solutions at this point because netstats pings, etc etc are not showing me anything, I just get a lot of Syn_sent connections without ACK's.
HELP! (And sorry for the wall of text)
have you tried setting up your APNs?
APN's
Yeah, I tried setting and resetting them a few times, even with a rep from the cell company.
I'm losing my mind!
Thanks anyways though!
Im using 21d. Seems to have somewhat similar problem. Getting unstable connections.
My problem:
phone kept switching from H to 3G to G and H again. Speedtest app revealed very low and inconsistent speeds..Reception bar also kept changing.
Phone was previously froyo. Im not sure if it's because of gingerbread baseband. I have some suspicions on that.

I agree. I think it's a GB thing. I'm on v21a, and I have the issue where upload arrow keep blinking, and I get the H -> 3G-> H.
EDIT:
I'm having this on v10d too
Hello,
I installed android 2.3.5, "[12 MAR][CMR][TMOUS/EU][Mgldr/Clk]Sensation XL Stk S3.5[2.3.5]v1.9[marc 0.1.9]kernel " http://forum.xda-developers.com/showthread.php?t=1348922.
everything work, only 3g, data connection not, which is very important to me..
I installed MAGLDR_CWR_5.0.2.6_flash_5_200_5, and UrDroid_Better_Data_Connection_Files, and nothing..
I have signal, phone, sms work but data connection not..
So, if anyone have idea how to fix this, please write..
Thanks
were the proper APN's for your carrier properly inputted?
I am new in all this story, a didnt do that..
So, how to do that? i hope that is a problem..
I fix connection, it was problem with my operator ,
but, i can use it only on browser phone aps, try to connect and quit..
I can use mail, android market, weather..
And, btw, no apn i select, if do that, i have no connection at all..
I just updated my Atrix 2 to the official OTA ICS 4.0.4 and after it took all day for my system to catch up with the new OS, My data is not working. No internet connective, UNless I'm on wifi. I have never had a problem before until I updated. I use Easy Batter Saver (app) and I reset the mobile network. That didn't work. I tried enabling data through the settings. That DID NOT WORK. I went to the settings --> about phone --> status and the only irregularities I noticed were
Mobile Network State- Disconnected
Sim ID- Not Available
- idk how to take the screenshot.
Any Ideas?
--- Found the answer!
It took a while to figure it out but this was the answer if anyone else is having the problem, It seems that the APN were deleted and the one that remained on mine after the update did not work for data connectivity. This is it. http://forum.xda-developers.com/showthread.php?t=1576199
I used the ATT phone and it worked fine and if you cannot receive MMS make sure to use both of them.
ALSO heres another link for more APNs

ICS data Lost
i lost the data connecion suddendly one day ago, this was working good. i restarted in recovery mode and did a wipe data/cache then add the apn's and now is workng again.
same here,i can not connect to 3G mobile data unless i change to airplane mode (after enabling mobile data and change to 3G network) and then to air plane mode to off.
or to restarting mobile after enabling mobile data and change to 3G network.
i tried 4 ICS radio images,but the same issue !!
i tried stock GB rom, same issue,but i tried another provider SIM with no issues, so , this was related to my provider network.
Hey guys, quick background. I bricked my SGS3 and had to have it replaced. I think I got a refurb phone because from day one I keep having the same issue. First day I got the replacement phone I rooted it and flashed CleanROM 5.0. Everything was peachy until I noticed that I have no 4G or 3G service. In fact, I had no data connectivity at all. My phone can make calls, receive texts no problem, won't connect to internet. If I restart the phone, I have 4G right away. After a few minutes, the 4G icon is on, but the phone won't has no data connection (when I say data connection I mean it will not go online, no internet, no android market, still have voice and txts). If I attempt to go on internet, I get a message saying "No Signal Found For Mobile Networks". I have installed Network Signal Info and right after a restart it says 4G LTE, data connected, upload+download activity. After a few minutes, it says 4G LTE, data connected, after a little while, it will switch to EHRPD, with data "connecting". Also, in the System tab, it will tell me my IEMI and version of JB running, next to "Radio", it says "unknow". WiFi works perfectly btw. My IEMI is perfectly fine,
I had it backed up. My phone number is still there.
Here is what I had tried so far: Switching into and out of Airplane mode, different programs that reset mobile connection, flashed different custom ROMs, flashed the stock kernel, flashed 3 or 4 verizon Modems, Data wipe, cache, Dalvik wipe, Odin'ed back to stock 4.0.1 ICS and had upgraded it to 4.1.1 via verizon software update, changed the SIM card, and reprovisioned the phone with that *3767*whatever the hell code. I'm out ideas.
If anyone has any other idea that I can try before I take it back to Verizon, please, let me know.

Did you go into your mobile data settings to make sure you're on CDMA/LTE? If not I would select and reboot the phone and see if the problem persists. I don't know if you have tried this but it's worth a shot.
I'm having literally the same exact problem with my mom's S3 except for it's not rooted, complete with 'download + upload activity' and 'unknown' radio. I've yet to find anything in my search, but if I do I'll post it here.

I did try that. Nothing seems to be working.
Hi guys,
I'm using moto g for about 2 weeks and everything was fine until yesterday. I will try to explain what I've chronologically. My phone isn't rooted. Android 4.4.2, 174.44.9.falcon_umta.Retail.en.GB, KLB20.9-1.10-1.9
For last few days I was testing some battery stretching apps, such as Juice Defender, 2x Battery, GreenPower and maybe one more, but I don't remember the name.Finally I've bought Juice Defender Plus as that app was something that I needed (control mobile and wifi in an intelligent way, but that's not the point). Before JD I've uninstalled other battery aps (but without reverting their settings to defaults). Then I've installed JD, configured it and started to learn JD with my wifi network, whatever.
Next day I went to work and I'm not sure if mobile network was working or not, but wifi network was ok. Updates, synch, etc. was working well. I've installed 2-3 new apps (don't remember, but it was camera360, total commander with few plugins, and maybe something more). Then I've left wifi network, entered car and connected with mobile network. From this point everything stopped to work. There was no connection to any site, no synch from google, weather, and so on. Icon on top of the screen informed me that connection is online (with H or H+, sometimes worse, but probably it doesn't matter). I've tried to connect with many apps to Internet, but none of them succeeded... I thought that maybe there is something wrong with mobile and after that, when I get back to wifi coverage, everything will rise and shine.
Unfortunately when I get back to wifi zone, phone found new network and connected to it. It doesn't matter what network it is, because few days ago I was working with that wifi net and more on that, laptop connected to that network works like a charm. As I said, connected, data transfer in 3g watchdog shows very little net usage (about 200-300B/s). Can't load web pages, can't sync. The same behavior as in mobile, there is connection, very little data usage, but nothing more, no web pages, no sync, etc..
I've restarted phone many times, entered in airplane mode, removed, cleaned and inserted back the sim card - none helped. I've checked ip, gateway and dns which came from dhcp router in wifi network. Everything was fine, addresses were the "same" as my laptop (beside ip address, which was different). I've checked what's up with JD, then I've disabled it, uninstalled..., checked transfer limit for mobile, turned on and off mobile, wifi in many ways. Checked proxy in browser (chrome).
The result was always the SAME.
in chrome: entered address, page starts to load, nothing shows and stalls, after a little while (tens of seconds) there was a message telling me something like: page is unavailable (I can't remember the right message).
in gmail: sync lasts forever, when I send email (to myself) it popups message about sending, but it disappears in a while, a no new email...
other apps, for example, weather on main screen, sync could last to eternity, and no new data.
Today, after whole day without wifi coverage I went back to wifi zone and tried to connect to it... and all emails, sync, whatsup and so on, updated. I think that, I didn't change nothing, but why wifi started to work? I don't know.
I've checked if mobile Internet works as it should, but without any positive results. In mobile there is the same problem as for a last 2 days...
Does someone know any solution to my problem?
PS: I've even tried to enter ip address of wp.pl host, and then phone redirected me to address: 194.9.223.70/ns/cs/deny.html?trx=...something&tpd=3&ts=somenumber&sid=HTTP_DRSTD&url=...mobile[dot]orange[dot]pl
Are you able to send & receive calls? Have you checked your APN as well? Wondering if one of the apps you've tried has changed a setting or set itself as some kind of proxy that your phone's still trying to use even though you've uninstalled it.....not sure......had a similar experience when I tried out a firewall app & removed it without disabling the settings it applied. Can't think of anything else, sorry mate

Yes, sms and calls works fine. APN is okey, moment ago I've sent configuration sms for internet apn from my operator. I know that it could be one of my apps, which I've uninstalled, but I don' know which one it was .
Might be worth checking device administrators in settings as well just in case the culprits there? Good luck

Checked that, there is only Android device manager (sorry, maybe there is another translation, I'm not using EN lang in my phone) enabled. The rest dev admins are disabled.
Factory reset. That way you start from scratch and if still a problem you can rule out any apps or incorrect config etc. Its the easiest way to narrow down the issue.

maybe it's the easiest way, but I think it's not an option if I want to know what was wrong...
Sounds like one of the apps is the problem, as you already suspect. You may have to concede and do a factory reset:
Settings > Backup & reset > Factory data reset​
Please make some effort... factory reset is not the first thing to do when sth is wrong.

I suggested a factory reset as this then rules out all apps and config you have setup. If the problem still happens after a factory reset then you have narrowed down the problem a lot. Possibly it will just fix it though.
However if you want to find the cause of the issue then factory resetting is not the best thing to do as you say. But you seem to have installed a whole bunch of apps in a short space of time so even if you find the problem I doubt you will be able to find out why it happened, ie which app caused it.
You will maybe fix it but never know what caused it or how to prevent it again.
If you factory reset and it fixes it you can take things more slowly this time, is install apps and configure more slowly until you hit the problem, then its easier to see what caused it.
As there was no chance to get other suggestions than "do factory reset" , I've made factory default. Unfortunately, without any change in my problem. Right now wifi works fine, but 3g/data is dead. I've checked my sim card in another phone and 3g/data didn't work too. So I've called to my telco and heard that everything is ok, but probably my sim card is damaged and that's why my data connection is dead. I will try to get new sim card tomorrow.

So those of us suggesting a factory reset were correct then. Had you not reset you would have spent wasted time trying to fix what now appears to be a sim card error. Possibly best not to tell people to 'make an effort' when they are trying to help.
