So I was having problems with my 3G connection the past few weeks, it just wouldn't turn on even though I had network reception. Calls, SMS etc. all working fine. I tried a few things as a fix work around but none of them worked.
Disable / Enable 3G - obviously
Turn off / on phone
Turn off, remove battery / on phone
Enable airplane mode, leave it on for a few mins then turn off
However, 3G just refused to activate. I was running Azure 1.0, not sure if that was the problem so I took the plunge and flashed Froyo (whitetigerdk's ROM) and to my delight 3G was working again.
But low and behold after a week or so I'm back to square one, exact same 3G issues. Is this a common problem? I presume that its software related but not 100% sure.
Does anyone have any suggestions on what I could try to resolve this issue once and for all?
Does anyone have any ideas?

I am only writing here after I tried everything I could possibly imagine with no result. Sorry the long text.
I'd like to hear ideas from you. Anyone with a similar problem.
I have a Blackstone, and never had even the smallest problem with GSM signal. But now I face the following:
- If I set the Band to "Auto", my phone connects to the HSPDA network with no problem, and I use internet and make calls normally.
- If I set the band to "GSM", sometimes it connect, sometimes not. When I manage to connect, if I try to use the internet, sometimes I lose the signal. When I am making a call, it frequently hangs up. The problem is random, sometimes I can use GSM with internet and calls for a long time, but suddenly it crashes again!
The solution would be always connect to HSPDA, but the problem is that on "Auto" the phone sometimes goes to GSM alone, and the signal breaks down.
I cannot be sure exactly when this problem began. But it was after I installed PDAVIET's Rom (WM 6.5 21053 and manila 2.5), and radio 1.17.25.09.
Among everything I have done:
- Flashed dozens of Roms always hard-reseting twice after. Tried stock Roms, cooked Roms with WM 6.1 / 6.5, manila 1.3 / 2.1 / 2.5.
- Flashed radios 1.13 / 1.14 and 1.17 in combination with all Roms. Tried with and without ripphone.dll's
- To eliminate a operator problem, I used my chip on a nokia for a few days, and didn'd have a single problem with signal, calls, internet. I installed a chip from another operator and faced the same problem.
Nothing I have done made any result.
Even using my stock Rom didn't solved. I used this phone for 8 months with no problem. So I came to the conclusion this is hardware related, with the antenna or something.
Thanks
All right, have been through a few more Roms and Radios and the problem remains unchanged...
Really looks like an antenna related problem. Apparently I will never connect to GSM again unless I take my device to service (have no guarantee), and be lucky!
But anyway, I found a solution to the connection instability and phone calls interruptions. Solved my life for now. It is very complicated:
*********************
HKLM\Software\OEM\UMTS
OpMode=2
*********************
This forces the phone to always stay in the 3G band. The "Auto" mode you can set in Comm Manager lets the phone change to GSM when the signal is low or whenever he wants, and my connection breaks down.
BTW, other modes are:
OpMode=0 (Auto mode)
OpMode=1 (GSM only mode)
OpMode=2 (3G only mode)
I know this may not be useful for anyone, but I just felt like sharing...
From doing a Google search, it appears that it's not an uncommon problem for people to have an issue with turning WiFi on/off and it affecting 3G service. Do others here experience this ?
What happens is, when I enable WiFi (I also connect to a hotspot), my 3G service is turned off. I can't place phone calls. When I turn WiFi off, I'm again able to make calls.

i've never had this problem as far as i know. i been running various cyanogen roms for the eris, since they became available.
It's easy to test. Turn on WiFi, connect to an access point, and try to make a phone call. I want to determine if it's ROM-specific (doesn't sound like it as there are posts over at Cyanogen's own forums with others seeing this) or if it's something wrong with Cyanogen's side of things.
Well I currently running kaosfroyo v14, which is part cyanogen part plain aosp. Wifi is broken this version, so later when v15 is out I see if works. not using 2.1 right now, so prolly can't be to helpful.
When I was on CELB (jumped on FroYo), connecting to wifi only caused a brief disconnect less than one second long. I'm not sure if it interrupted phone calls as I was never in call while connecting, but I can definitely say that I was able to make and recieve calls afterward.
never had a problem with wifi on and making phone calls..
Used the following roms:
white widow
evil eris
damageroms
Fresh Rom
eris lightning bolt
calls dont use 3G anyways. when in a call your phone drops to 1x

Yes, you're correct (I know this myself) but what clued me was seeing the "3G" icon disappear.
Right now, in the status bar, I have the 3G icon with (2) arrows flickering, as well as 2/4 bars for signal. WiFi is OFF. Turn WiFi ON and the 3G icon gets replaced with the WiFi icon. I place a call .... and it works.
I feel stupid now !
I swear, I ran into this multiple times otherwise I wouldn't have searched and posted posts and threads about it.
Hello, I am hoping someone can help me.
Recently i have noticed my phone keeps losing signal, often seeing no bars are even ! , i have not performed any recent hacks / mods it just started happening.
If i change the base band from AUTO to GSM i get signal , if i select WCDMA i get ! , i am assuming that since its default at AUTO that when its switching to WCDMA its messing up (altho i really would like advice if this is true?)
i have softreset and hardreset and currently have no 3rd party cabs etc installed on my o2 stock rom yet the problem still exists.
any help people ..
How old is your sim card? I had a similar problem a couple of years back, turns out the older type sim cards aren't capable of doing 3G, walked in the store told them the problem, promptly given a new sim card, 2 hours later all up and running again.
Never used the stock rom but may also be worth checking in comm manager, there may be a toggle switch for turning 3g on or off
originally last year when i got hd2 i had an old sim which was replaced, my stock rom doesnt have the toggle (im sure i can turn it on with a tweak) , however the problem isnt switching it on or off .. the problem is when its on my phone wont get a signal and it used to work
Hey everyone. I've been having issues with my data connection and I'm trying to figure out what is causing it. I am using CM 6.1 RC2 and I have the updated radio from the vodafone rom.
For example, when I enter the market, about 50% of the time I get a network error after resuming from sleep and have to click retry once or twice before I can do anything. The data connection is just not reliable anymore (yet before this issue it always was).
I'm just wondering if there is an issue with RC2 of CM or if it is the radio update causing this. Can anyone comment?
I'm not sure this would be related, but after flashing 6.1.0 on my Dream I find it stuck in EDGE occasionally, usually when in the car or after, and in places where I get solid HSPA before 6.1.0. So far, I have to reboot to get HSPA (or 3G) back. There are some notes on updated radio and a kernel to address some radio problems, is anyone else seeing this?
Hi,
I have similar problem. My legend is not with the latest radio or kernel.
The specs are:
CyanogenMod Legend 6.1
Radio: 7.05.35.26
Kernel: 2.6.29.6
The problem that I see is: During the night when the phone is not used it looses the data connection. When I turn it on in the morning there are no mobile network indicators. I have to reset the network ( by airplane mode or reboot) ot get back my data connection.
During the day there are no problems.
I suspect that this happens because of the weak 3G signal in my area. However I use auto setting. ( 2G and 3G)
When I was with stock ROM I haven't such issues with dead data connection during long sleep.
EDIT: I have just upgraded the radio to 7.08.35.21. I will check how it works tonight.
BR
I'm having similar trouble with CM 6.1 released just a few days ago...
I've posted this to Cyanogen Stable Forum for Legend:
h t t p ://forum.cyanogenmod.com/topic/11966-cyanogen-61-htc-legend-problems-with-3g-connection/
I think I've similar problem as you...
I have updated the radio to 7.08.35.21.
This morning when I woke up I saw no data connection again The signal strength indicator was full with bars!
Anyone has any clue?
I've been having some data issues too, I've had to go to and from Flight Mode in order to get any form of connection (data OR telephone) back, and I occasionally get stuck on GPRS. Toggling "use only 2G networks", waiting for the data to come back and then toggling it off again gets EDGE or H back, but it's pretty flaky compared to RC1 and the older radio.
I think i have the same or similar problem.
It looks like I have a data connection (3g is showing and signal strength is almost full). But when i try to connect to facebook, browser or somthing else what needs a connection it cant connect.
I have a taskkiller running when i kill all the task 90% of the time i will get a connection.
I have the same programs on my phone when i used 2.1 and with 2.1 I never had this problem.
Strangely enough it seems like mine is working much better lately. Maybe there was something up with Bell. I haven't gotten the connection error in days.
After update to radio 7.13.35.05 I haven't had this sissue again.
I will continue to watch he behavior.
After a couple of days of using my Nexus 4 i've noticed a problem with the way it handles the transition between Wifi and 3G internet.
Usually it works just as expected, when I switch Wifi off (or just go out of wifi range) it automatically switches to 3G internet (coverage icon in blue). The problem is that sometimes, after switching wifi off, it doesn't turn on 3G data (coverage icon remains grey). The only way I can get 3G internet back is turning Airplane Mode on, and then off again. ¿Am I missing something here? I've seen other people having this problem with other phones, but no workaround yet

This happens with my gf's Galaxy S3 too...
I think this is just a network coverage issue. My old mytouch 4g slide had the same problem. Usually it switches quickly if I'm in an area with great reception. If I'm somewhere with weak reception, it takes a little longer.

Well, I don't think this is a network coverage problem because when this problem happens, it can stay for hours with no 3G internet, it just doesn't even try. But then I switch airplane mode on and then off again, and it achieves 3G data connectivity almost immediately. Also, with the same SIM card I didn't have this problem with an iPhone 3GS.
Well, i've been investigating a little bit, and I've just found it in the AOSP issues tracker as "Android Issue #2207"
I've also found some apps like "3G Connection Fix Free" that seems to try to fix it
I'll try them and report back my findings
I think I have this problem too sometimes. I think my phone has other issues, I'm about to send it back to Google because it keeps dropping cell signals as well, but I definitely have this same problem.
Yes, it happened to me as well yesterday.
After I had more than ten hours at home using wifi, it can't switch to 3G automatically when I left home. The only way I did is reboot the phone.
But if I just connected to wifi for few hours it is OK.
Before I use One X, I don't have this problem before, but the problem is I can't access to internet once I am using wifi for more than 36 hours about.
I think there is big problem for Android system related to wifi and 3G access.
I don't think it's a nexus issue at all. It is definitely something else. My phone hands over form wifi to H+ in a matter of seconds every-time.
I believe you might have a coverage issue.
I am having the same issue, and can confirm it is NOT related to coverage. A reboot of the phone will immediately fix the problem. Have also tried disabling the mobile network, then re-enabling it, with no success.

Well, nothing i've tried has worked so far. It looks like if it stays connected to Wifi for many hours (for example overnight), it just won't switch to mobile internet unitl I reboot or do the airplane mode trick. I also have wiped everything and reinstalled the stock rom, but the problem is still there. Has anybody fixed it?
Had this problem with my Nexus One, with my Transformer 300 and now with my Nexus 4.
I use German provider O2 and after doing some research, many people suffer this problem and have O2. I thought it was related to my SIM card and I ordered a new one without success. My wife has O2, too. She never had a problem, not with her HTC Desire, not with her Galaxy Nexus.
I worked around with free app WifiFixer Free, which connects to 3G every 60 minutes. This doesn't seem to work on Jelly Bean, though.
The problem is all but new and I am out of ideas. I now use an app that enters and leaves airplane mode upon leaving a Wi-Fi network. But it yet has to prove that it works...
Any news in here? have the same problem and don't know how to solve it. It's so annoying

I have this problem too. Completely stock nexus 4. It doesn't happen all the time but when it does its very annoying.
