I have problem with 3G on this phone - I almost never have internet signal. Would external antenna help? Or maybe sth is wrong with my phone / settings? I sometimes see the signal for Edge network and can use internet, but most of the time - nothing. My network should have coverage in my area (judging by their map). WiFi works without problems.

try reflashing!!
or maybe put on airplane mode and reboot and then put
airplane mode off..
or just get a warranty!!!
Thanks, I will try it. Warranty is out of question - it's old, used phone I bought only for testing apps (but I'm using it for other things now because it's quite good ).
It will also help if you set the access points manually for internet and mms
And if you can manually select the network
Best of luck

Please help:
I'm on CM9 19 6 nightly. Using Semaphore kernel without any modifications to the scripts.
The problem: My signal keeps on going out at regular intervals.
I've used XXJVU, DDJV5, XXJVT, KF1(Nexus modem for ICS) and various more. I stay on the modems for a week and then change to another one. The latest one is DDJV5 which I have been using since the past 2 weeks.
Tried all of the modems I could lay my hands on. Nothing works.
But the moment I come to work, the signal keeps fluctuating over the day. Sometimes it would be out for 10-15 minutes. When it's back, it would get back to giving -65 .. -71 dBm. It would stay like that for a few minutes and then it would be gone again for another 10-15 minutes or so.
It has turned into an OCD where I keep checking my signal.
This does not happen when I'm back home and then I'm back to getting good signal.
Yes, this looks to you like a locational issue. I thought so too. BUT, how did I get so good signal till a week back at work?
Question: What could have made this mess to my signal reception? How can I solve this?
No, all my syncs are OFF. I keep my 3G turned off and only use it once an hour or so for a few minutes. I don't use any signal consuming apps.
Also, sometimes the 3G would work even without the signal.
Another thing, sometimes there's a (x) sign at the signal bar thing and sometimes there is no (x) without bars.
As a cure for the OCD, I've taken an off from work today just to get some rest from checking my signal every now and then. And maybe find a solution.
I'm on Vodafone India.
Indians, I am on Vodafone India in Pune, Hinjewadi Information Technology park. Maybe Pune guys can help me out too?
maybe the phone changes the network mode.. 2g 3g or i dont know , try to put in in 2g only mode , or gsm only mode.
When the signal bar shows with a "x" it means the network is not available...go to settings and change the Network mode to "GSM Only". It will solve the fluctuating issue but network speed will be limited to 2G only.

Thanks, let me try it out.
Where is the network changing option to GSM only in ICS?
Okay, I guess it's the 2G mode.

Is going to 2G mode my ONLY option?
How can I fix this and get back to using 3G?
Update:
Changing to 2G mode fixed the problem. BUT...
I have a few questions now:
I want to use 3G but at the same time I don't want the signal to fluctuate between 2G and 3G—want to get constant 3G connectivity without signal fluctuations. Is there any way I can fix that?
I remember reading somewhere that going to recovery and changing permission helps this.
Anyone knows how to change the permissions so the signal fluctuations stop?
I have done a lot of reading on XDA but I haven't noticed an issue like this.
CM9 guys, anything please...

I have the same issue mate...using 2G is the only option to get signal without any problem.
The problem doesnot lies on your phone but the problem is with the operator. The area where you live hardly 3G signal reaches there (same problem with me).
You got two options to fix this issue:
1. Change your Network Operator
Or
2. Settle to another location where 3G signal is fully available

Both the options look impossible for me at the moment.
I will start living with the hope that the operator brings us some decent 3G signal here.
Thanks a lot anyways. It was helpful. Hope others facing the issue can learn from this thread. :good:

Complain to your provider, very loud!
:gooditto the same problem occured to me on Vodafone (Chennai) tried all modems listed above nothing worked ...Used to lose signals all the time with 2g data on especially at my workplace intermittently for 3-4 months ever since I upgraded to ICS..Sometimes used to lose signal even if data was off..multiple reboots/restarts gave no solution ..issue persisted across all the 15+ roms i might have flashed over the past 6 months..
Finally fed up I ported the number to AIrtel..everything works like a charm on JV9 I must say now..can vouch it's a network issue at the location
I am getting constant 5 bars on the 2G network. 3G gives me 2 bars at max.
Asked Vodafone about the future of 3G in my location and they said "We are spreading, sir. We will keep you informed".
I've had this problem too when the phone was constantly switching between 2G and 3G/3.5G. Try adding "Toggle 2G/3G" to notification drawer, set the "Network modes" for it to 2G/3G Only or 2G/3G Only/3G+2G. Switching between modes can take 10-20 seconds, but you should be able to test if you can get good enough 3G only connectivity (in case it is just a network switching problem like for me).
If you want 3G only, Dial *#*#4636#*#* - Phone information - WCDMA only.
Today all of sudden my phone disconnected from carrier network, Tmobile. I tried everything and I can't register it back. It shows signal bar but can't make any calls, no mobile network. WIFI is working.
Anyone has the same issue?
Had that issue as well before. Enable airplane mode then disabling it worked for me.

On my K3 Note, I can't pick preferred network mode on ANY rom/firmware.
I've tried everything, but it always sets the default preference which is 4G>3G>2G.
What I need though is permanent 2G and I can't set it this way. (4G signal is weak on my operator and then it keeps switching between 4G and 2G over and over)
Is there any way to entirely disable or block 4G on a phone so it will never set that mode again?
Any help would be appreciated!
Any help guys? No one knows what could be the issue?
I tried using the *#*#4636#*#* code and set the "GSM Only" but it still doesn't work.
Is anyone else having the same issue?
Edit:
Also what I've noticed is that while using CyanogenMod (atm), it stays on 2G until I turn the screen off. Then it goes back to 4G.
After turning the screen back on it then goes back to 2G again.
same problem here when dialling number it said invalid MMI code and when switching to 4g the other network appear no signal.. hope someone here have solution. i try several roms but same problem issue.
Well after a lot of fiddling, it seems it works on the stock firmware, but the mobile operator as himself has quite troubling network.
But I think we are slowly coming to a conclusion..
Hi all
The past 2 days I seem to be having an issue with intermittent 4G coverage...
It will connect to 4G but have a small X next to it in the top menu. I receive no internet however.
What does the X mean as I can't find the answer anywhere, and is it an issue with my phone or my service provider?
I am on EE UK and running 7.1.1 Beta NPF10C
I have restarted, turned on and off airplane mode, reset my APN to no avail.
Anything else you need to need to know I will provide
Thanks in advance
I have had the same problems occasionally & I think it's an EE fault. It basically means you have a 4G connection but no internet access. Toggling mobile data off, waiting a minute or two, and re-enabling seems to get a new connection.
