bug not getting 3g when avail. - Galaxy S I9000 General

anyone find a workaround to the bug that at times when you move into a 3g zone for a zone where there was no 3g the phone will not pick up 3g.. i have tried everything and the only fix i have found is to reboot the phone.. turning on/off data does not work it goes back to edge..

I dun seem to have this problem, and I go in and out of 3G zones everyday as my basement carpark can never pick up a 3G signal

i have this issue aswell ://

Tele2/Comviq

Im having problem with my network connection.
Everytime it has to change from the sweden 3G network to my Tele2 GSM network it looses connection. This roaming issue is very annoying.
Most of the times it will register to network again but it takes several minutes.
Sometimes I have to softreset.
Another problem: I seem to have full 3G-signal but when I start PIE and a connection is started the signal goes down... Why on earth is that?
Anyone else noticed this?
recall when 3 first started with 3g here
they had the same problem the problem was
not with the phones but with the way that
the they handled the roaming from 3g to 2g
people had phone conversations ended by the
changing from 3g to 2g and such
think they fixed it now but it was not a phone issue
I need help with tele2comviq 3G
I have an htc diamond, I successfully conect to 3G for free but it can't surf internet but only works with skype. Any suggestion or help?

[Help!!]I can't hook up to HSDPA with my Kaiser anymore....

Hey guys, My device is Kaiser(TyTNII) and AT&T is my operator.
I live in Philadelphia, US.
Before yesterday my TyTNII can access HSDPA (with "H" symbol on the top right) when I try to use internet.
However, I use Kaiser Tweak to change some setting of my device and suddenly my kaiser doesn't recognize HSDPA network anymore, I mean it will only show "3G" on the top right. I have checked all the settings and everything seems fine.
HSDPA function is checked and same as in the Kaiser Tweak.
Can someone help me out here?
Thanks.
i have the same problem, cant go into hsdpa or even 3g only edge. and it seems to have happened after using kaiser tweak also.
Got some help over in the Kaiser forum that helped me. Go to your comm manager then settings/phone/ then go to band and switch your network type to wcdma. after it updated the network i switched back to auto and it seems to be working so far for me. hope this helps you out, something you could try.
I seem to have the same issue but the above solution doesn't help. Whenever I set the phone to do HSDPA through Connections I loss all data connectivity, once I turn it off HSDPA I get 3G.
Is it possible for radio settings to survive a hard rest / ROM upgrade or is the HSDPA side of my Tilt broken :-(
Any insight or help would be real appreciated.
Several times I have gotten "Warning: Unable to change GSM/UMTS Band, Please try again later."

OK is it possible for this to be tower related? What I mean is I drove about 4 miles from my house, got a better signal and surfed the internet using HSDPA. Now I'm back home and HSDPA is chocking and giving me "unknown error 0x80072f78"
What He!!?
One note on my HSDPA trouble, it must some how be related to the one tower nearest my home. When I go anywhere outside a 5 miles radius (I live near the tower) everything works fine.
Here is the weird part, every where else the phone will switch from HSDPA to 3G to Edge and back no problem. Here in town it locks into HSDPA and refuses to switch to 3G or anything else. I don't know if it means anything but it seems to get an IP address I can ping but I don't get any DNS info!.
Now how can I convince AT&T that there's a problem when their support person denies there is any HSDPA services and I should only expect 3G?

3G network speed problems

I have problem with my 3G network speed...I called the support for my operator..they told me to restart the phone..I thought have they not anything better to come with, but when I checked before I did reboot I got 0.12 mbit after reboot I got full speed of 3.5 mbit to my surprise..
I wonder does anyone else experience the same problem ?
The speed seem to be slower the longer the phone runs without reboot..
I have not installed any apps or anything at all..
most likely your phone is set to auto switch between 2G/3G and it had dropped down to 2G due to a bad spot in coverage or a temp glitch in your carriers 3G service. a reboot would get you back onto 3G, which would explain your experience.
If it happens again, double check the network coverage icon and try going in/out of airplane mode or manually forcing 3G from the settings menu. Only if those measures DON'T fix your issue, but a reboot DOES, would there seem to be a real issue.

I agree with _pigro_.
I have been doing the same. This is cos of the way my cellphone carrier provides 3g in my city.

Wow, this is ridiculous and why is this happening?

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.

[Q] Dropping data connection

anyone experiencing data drops particularly when the phone is in weak 4G coverage? It acts like it cant switch between 4G and 3G. sometimes it might take 5 min or more before it will reconnect to data. the phone works fine when it is in a strong signal area. So far I have just experienced this behavior in low signal coverage.
Yesss! Experienced that yesterday. But came back on in 5 min. Usually fixed when u go to settings and switch from the lte to GSM and back to lte but haven't had trouble with it today

Yours is the first case I've seen where data drops altogether, most have just been going back to 3G too often.

I am having the no data issue as well! I leave my house (on wifi and supposedly 3G or 4G) and I want to start listening to music immediately in my car but I have no data connection once wifi is off. It can take over a minute or more to get a data connection! I was wondering if this had to do with LTE protocol negotiation, as this is my first 4G phone. However it seems way too slow and its very aggravating. When it does get data back, it is usually 4G not 3G. Toggling data mode on and off doesn't fix it. I have not yet tried toggling between CDMA and GSM.

does it only happen when you're leaving wifi and going to cell data?
My experience with data connection was spotty for the first couple days. Going from WiFi into 4G then 3G on the way to work required a reboot to pick up the 3G after I arrived.
I think I may have found my issue.
Settings -> More... -> Mobile Networks -> Network Mode
Was originally set to "Global". I've found that "LTE/CDMA" works better for me.
hope this helps some.
