I have a rooted vibrant running stock Tom with the j16 update and my 3g works intermittently at best. Is there any fix I can do myself?? Its understandable if I were in a cave but I'm getting full bars and my signal strength is -89 dbm 12 Asus. Please please anyone. I'm almost to the point where I'm about to call T-Mobile and see if they can switch me out a different phone. I hate the idea of paying for the web and nit being able to use it. BTW, if I pull my battery off and restart the data connection will work for about 10 mibs

I'm interested to see the answer/suggestions as well, I've been having the same issue.
It will work then not, a restart or going into flight mode and back will get it working for awhile. It does it over Wi-Fi too..(Sound familiar?)........... It's done it stock, rooted with OCLF, with ji6 and now even with Bionix 1.9
Yeah I mean my wifi works all the time but now even when I do the airplane mode it doesn't bring back my 3g data connection. Its driving me bat **** tho. How about u?

How good it the 3G coverage in your area?
Try a market app called Map Viewer. At home I'm out of 3G coverage.
OK I will try to download it and let you know

Do a factory data reset.
Sent from my SGH-T959 using XDA App
well I found out from the map that my 3g coverage system work is supposedly non existence. Go figure. So I'm basically getting snippets of it. If I do a factory reset I will lose all my info right? And when you say reset do u mean using Odin and flashing stock 2.1?

Do it from the phone settings, privacy. Yes, u will loose all yr apps, but save them using appsaver from android market first. Your new rom update will still be there. Hope this helps. Thats what I did to correct my 3g issue, just like what you described.

just throwing this idea out there. tmobile could be doing tower work in your area. i experienced this for awhile where data was just iffy and wasnt very reliable. this may happen on and off for a few days.
Hey guys, (Did extensive search before posting this)
Whenever I get a MMS the messages show a download button but will not download. I have tried turning wifi on and off, turning mobile data on and off, rebooting, using stock app and Go SMS and nothing is working. I looked in APN settings but do not know if they are right or not.
The issue just started recently, I have had the phone about a week and they seemed to work at first.
Please help,
This is driving me crazy and is frankly unacceptable in 2012. I saw some threads about old Galaxys having this issue.
You have to be on mobile data without wifi for them to download.

Thanks for the reply, but I have tried turning wi fi off, which in turn reverts to mobile data and still no success. Could it be that I also use a micro cell? My carrier service is literally the worst possible at my house without the micro cell. This is quite unfortunate if so.
I think wifi has to be off when it is initially coming through and yes, a micro cell will do it. Is it a voice micro cell or data?
Sent from my GT-I9300 using Tapatalk 2
Its a voice micro cell, but it also transmits a 3G signal. Not sure of the speed since I always use wi fi.
This is boggling my mind. Are you telling me that it is not possible to recieve a freaking MMS message created in 1982 (sarcastic) on a 2012 LTE device if I am in a wifi network. WTH. That is crazy to me.
So are these images gone or do I need to turn off wifi and turn off the micro cell to download?
Thanks for your help btw.
So I disconnected wifi and disconnected my microcell and clicked download on Go SMS and nothing, error message. Pulled up the stock SMS app and clicked download and after a half minute or so the picture appears. The picture then also shows in Go SMS.
I guess the solution is no MMS while at home which is a bit frustrating coming from another device/platform where this problem would not occur.
Thanks again.
I have the international GS3 on AT&T. My phone automatically downloads MMS if only mobile data is on or both wifi & mobile data are on. I believe it is your microcell causing your disruption OP.
Sorry, my international S3 also only downloads MMS if only mobile data is on.. I have yet to see it auto download when Wi-Fi was on. I would say it could be the microcell in this case though.

Not true. I am on WiFi 90% of the time and I still get MMS
Sent from my SAMSUNG-SGH-I747 using xda premium
When mms comes in the WiFi should temporarily shut off and the radio picks up 3 or 4g in order to download it. U honestly won't notice any seperation. If u honestly can't receive them, check your apn settings
Sent from my vivow using Tapatalk 2
You are getting mms when you are away from your home/microcell, correct?
hmm, i just noticed that mine has been doing this lately too. MMS won't download unless I turn off wi-fi. I'm on t-mobile
I've recently noticed a weird network bug on LFB. If the phone loses signal (on subway etc.) with data on, when signal is available it acts as though the SIM was refused by the network continuing to display Emergency calls only. If I turn data on and off it gets weirder (see screenshot).
The only way to fix it is too reset the radio, with flight mode, or *#*#4636#*#*
It's definitely not a hardware fault since, as you can see it still can connect to the network. It just acts as though the connection was refused (or alternatively does something weird that causes it to ACTUALLY be refused)
Anyone else experienced this??
The phone is an original BTU using unmodified LFB on China Unicom

Are you able to set/receive calls or send/receive SMS? What about USSD codes to your provider?
I've already read about other users complaining about this issue, I guess it's a software-bug in the display.
No. I'm not sure if HSDPA will work in the example pictured. I was in a hurry to make a phone call so just quickly snapped the screenshot then reset the modem.
Messages will get service unavailable. Incoming ones don't get received until I reset

LFB is a poor modem firmware .

Yes, I've experienced the same thing a couple of times since LFB on carrier Telia in Sweden.
It reminds me of the phone/modem problems with the SGN which they never fixed before I sold it.

Washington D.C. has no GSM coverage inside the tunnels. Only some stations have coverage. Only Verizon and Sprint with CDMA devices have service on moving trains.

You can flash DXLF3.. It works so much better than the LFB radio.

Beijing.
Well 2G is okay. But it sometimes will lose it briefly in the transition from 2g to 3g.
Only Beijing subway line 4 has China unicom WCDMA coverage. the others are limited to 2g at best (except the overground lines, but even they are patchy)

Having updated to the stock LFB ROM and modem (UK, unlocked, unrooted), I'm really perplexed about the behavior of the phone data reception:
(a) 2 weeks ago, I tried using data connection in a friend's flat in Balham (London), could not get ANY data connection all weekend.
(b) Last weekend, data was consistently perfect and fast anywhere in the same flat, all "H+" 8Mbit and lovely.
(c) This weekend, same place but NO reception again, not a saussage. Voice phone worked fine, just no data at all.
And, yes, I've seen "emergency calls only" sometimes even when there is apparently a strong signal.
Back home again (Portsmouth), phone works fine.
On the plus side, battery consumption is wonderfully low!
Can anyone explain what's going on? It feels like the data connection is sometimes reluctant to "log in" or whatever is does! It seems to have a mind of it's own.
Thanks!
You may want to try another modem like DXLF3. It has better data network stability especially in cities or areas with faint signal.
I am planning to upgrade to the LFB, but i am not rooted. Want to be sure if i have problems with the modem signal, do i have to be rooted to install the new modem driver??
Thanks in advance...
Hi
Really weird problem my s3 has Been working fine until I woke up this morning and it is showing no mobile network but allows data connection still but not able to make any calls.

Right I turned it off took the SIM out booted back up without SIM the rebooted again with SIM but the signal still keeps dropping off I only get signal for a few seconds. I normal get really good signal where I am. Also battery is dropping quicker then normal I guess that's down to searching for signal though

orange/t mobile are doing quite a bit of network repairs and upgrades at the moment ahead of 4g, so that may account for it, try going networks and selecting t mobile, always get better signal like that here

I've noticed lately I'll be able to connect to data one minute and the next I don't.. even though I have full bars and the 4G icon is spewing its orange lines... only thing that fixes this is a reboot, then magically I have connection again.
I'm running stock 11c... anyone else have this issue?
My wife had the same problem a couple days ago. Our rom is stock 10o. At least this phone boots a lot faster than my old atrix.

I've experienced that as well. I'm currently using the ported stock Jelly Bean Rom and I have the 4GLTE symbol with the orange bars but when I try to load a YouTube video, it'll keep loading without showing the video. But when I reboot, it'll start it, but then when I want to watch another, it will just keep loading. I can still load up the Internet and the xda app but I can't watch videos.
Edit: So it's not that it won't load videos, it just takes a long time. I believe it's just not receiving LTE like is has before.

You may have tried this, since you mentioned the only thing that fixes the data connection is a reboot, but have you tried putting the phone in airplane mode and back again? That works for me when mine is stubbornly showing there's a data connection where nothing is happening.

I have done the airplane trick and that temporarily fixed my issues when I was on the stock rom. I also went in and got a new sim which seemed to help. I haven't noticed it as much since the new sim.

I've tried turning data on and off but that doesn't seem to work... haven't tried airplane mode yet.
I'm on 10o and I'm having the same issue with data. It is the radio because I've had this issue with other phones in the past and with them I had to flash different radios for a fix. Hopefully it will be fixed when they release the official JB for us Att users.

I've got the same problem as well. Often times when I am in an area with full bars and I get the 4G LTE symbol, I get no data at all.
I'll chime in and say I have the same problem as well. It affects me both on WiFi and on HSPSA. I can only describe it as incredibly annoying.
