3G network problem

Sorry for my English ...
I have a problem with phone network in all roms (Cyanogen, Gingerbread Stock, etc, and based on those).
As I read through the forums, people know it as "network ghost". That is, the phone network says it has, but in reality the phone is not network and gives off if they call me.
If I put the phone in 3G mode, the phone loses the network. But if I put the phone in 2G mode, the network apparently never lost.
Can you help me solve this problem for the phone so do not miss 3G network?
Currently I have CM Kang P204-35.
A greeting and thanks.

Enabling HSDPA on Jelly Bean

Hello guys
I have been performing various rom installation on my Samsung Galaxy S GT i9000 but everytime it was only GingerBread Based roms.
The second i switched from to ICS and to CM10 JB now, the problem i have been facing is network mode option which is not present in GT i9000 when i was on ICS and also in the present CM10 JB.
I tried many thing but none worked
NOT WORKING
again tried to enter the code *#301279# but that also dint worked.
And my network is 3G enabled since i have tested the same sim on my another phone which is a SGS II running on stock ICS and 3G is working perfectly fine on it.
So basically to enable 3G on my I9000 i would need to change my network mode which at present is not available in my mobile network settings.
HELP ME OUT.........!!!!!!!!!!!!

I must say that you din't even helped me with your statement as i feel you haven't read my problem properly. We have the best network signal availability in my area at present and as i said 3G is working perfectly fine on my sgs II which i already mentioned because i'm able to select the network mode manually from the mobile network in wireless & networks settings.
And not to forget the sim i used for testing 3G on my SGS II in actual belongs to my secondary phone - SGS GT i9000 which is currently running rooted and Running on CynogenMod 10 which is in alpha stage,
And for the data usage on - dude i'm no noob to post this question without me knowing how to use a phone properly.
And hey i did have my data usage on but in that attachment the data usage was off and it was just to show that there is no network mode selection available in the mobile networks settings.
I HOPE YOU GET IT

Since i got ICS on my SGS+ i cant get HSDPA. With Stock GB it wasnt a Problem, i had it almost everywhere when neccessary . Ive tried now 5 basebands, and sometimes i get it for 3 seconds.. but that was it... i'm in germany (NRW) and got e-plus as provider.
Thank you for youre help

Try to switch your mobile network mode to "GSM only" and then back to "GSM/CDMA auto". Try rebooting your phone, clearing cache/dalvik or fixing permissions.
Also, as far as I know, some ROMs do not support auto switch between 3G and HSPA (3G icon is displayed all the time). Usually custom ROMs switch between H and 3G to save power (H is used only when bigger network traffic occurs, in order to speed up your download speed), but many ROMs do not have this feature.

Forcing 2g, rebooting, etc., doesnt worked. I know that H is used for big traffic, but ICS dont even want to enter it when i download 10mb+ files..

hey there
as u might have seen im on eplus too and i faced such an issue several times with different phones
what i figured out was that in some cm9 roms the mobile hotspot (dein zugangspunkt ist ja normalerweise glaub ich internet.eplus.de ) is not available or there are mistakes in it so just get to the eplus providers homepage and check if ure zugangspunktname and all the other options dealing with it are set right
hauste rein

Everything was ok, now i changed back to gigabread+ from texten...
HSDPA works fine, seems so that ics is blocking connection like divibyzero said.

ICS doesn't block it you probably need to set up your APN correctly which is what I think the guy before me was saying too

[Q] 3G Data Issue

Hello,
I've read a dozen threads on this forum about this problem that I have, but I couldn't find anything that can fix it.
3 Weeks ago I bought a Samsung S Advance I9070, and everything worked fine till today.
The main problem is when I switch on the data network mode nothing happens, the data icon doesn't appear next to my signal bar ,as it once did and my internet doesn't work.
What I've tried so far:
Check apn settings;
Delete existing apn then manually insert them as my carrier asks.
Delete apn again and sent a free sms to carrier center and get a message with automatic settings,activating those settings.
Erased everything from my phone , factory reset, wipe cache, restore to a 3 days old backup (when everything was fine).
All of the above with no result.
The only thing that worked for me is the change I made in network mode -> i put gsm instead of gsm/wcdma, but from what i can figure this disables my 3g completely , leaving me only with an edge type of connection.This last change gave me acces to internet but only with an E icon(probably from edge, i have no real idea).
The phone has 2.3.6 Gingerbread , I haven't made any change of ROM, I only tried once to install JB through kies but the program failed and the update didn't even start.
I know it's a long post but, I'm kinda "scared" by the fact that I might need to return the phone.
Is there a way to fix this?
Thanks for your time!

Do you have ok network coverage for 3G? Maybe that could be a problem.

Well this problem appeared at home and until today I had 3g signal,it's kinda hard for me to believe that the entire 3G signal got lost in 1 day, but I will try it somewhere else and see if there's a difference, Thank you for your fast response.

Try flashing some other Roms like XXLQB/XXLQE.. You can search XDA for flashing roms..

Today I flashed a JB I9070XXLQE_I9070COALQ1 official firmware via odin.
At first I thought the problem solved, because I saw the H/3g icon next to the signal bar, but when I tried the internet ... i was disappointed.
I then reset to factory settings and cleared my cache like I read in some threads on this forum , and I got fresh apn from my carrier, but now when i activate the data network mode, the icon's missing again and ofc the internet doens't work.
Is it possible that the 3g is broken? even though i can use internet via edge?

Try selecting WCDMA mode only and see if u can get 3G signal...Else call customer care and ask them whether 3G is activated for ur number...

Any fix for this?

Unfortunately, no.
I've been using the GSM only option for the past days , until I have the time to take the phone to a service or smth.
A weird thing happens though, if I switch to gsm/wcdma and reboot the phone, in the first ~2 minutes after restarting I get 3g signal and I'm able to connect to the internet.(maybe the 3g service crashes ).
Probably before I take it to service I'll try and flash a new JB and do the apn trick once more, maybe this time I get lucky.

HELP: impossible to receive phone call when 3g is on

hi,
since few days I got the following issue :
when the 3g connection is on, I cannot receive (or I cannot make) any phone call as the device completely loses the operator signal and some times I have to reboot it to restore the gsm signal. I noticed tha this happens only when the status bar displays "3g" icon, when in " H+" it works properly.
I put the sim card in a different device and it works, so it is not a network problem.
the problem is that I got this issue with a custom rom ( lg stock based) and then I flashed cyano 11, but the 3g issue is still there!
Could it be an hardware problem?
Has anybody any Idea how to solve?
thanks

What kernel you use?
I've been using some customROMs and never had this problem.
Try a factory reset, flash again KDZ and try other customROM, like BeanStalk and test another kernel (I prefer iodak 9.95)
The only way to find out if it is a hardware problem is testing.
Best Regards. :fingers-crossed:

There has been a discussion about this already somewhere, I remember @Flying_Bear participated too. For me personally network doesn't work at all (no calls, texts or data) if it's displaying 3G, no matter which roms I use. On H or H+ it's working properly.

I tried everithing: different kernels different custom rom, different original stock firmware...nothing: can we consider it some HW issue?
