[Q] Galaxy S I9000 - No Network Signal

Am facing a weird problem on my Galaxy S I9000. Some days before, I went out of my Carrier Hot Zone, i.e. on Roaming and lost network signals for the entire stay of my roaming period.
I have inserted the sim card in another phone and it worked fine. But on my Galaxy S, now, even in the hot zone, i.e. my local network does not show me any signal strength except emergency calls. Again, sim card works fine in another phone.
Now my Galaxy S won't accept any sim card and shows no network signal. I have tried flashing different ROM's and Modems with no luck.
Any solution to this? Thanks in advance.

Hmm,
Are you sure that Airplane Mode is not active ?

I have the same problem, after a root my i 9000 y lost signal from my carrier. i have tried dierents roms and modem with no good results. any help? i appreciate... thanks

Try flashing another modem

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

samsung galaxy

:crying:I'm facing some problems with my duos s7562 when using 3G connection. that is when I set the 1st SIM card to 3G (or auto) for a while it works then for no reason I'm unable to make any calls from the outher SIM and also if people try to call me the phone seems off. The signal indicator always shows good signal.
Already tried to exchange SIM cards between slots and nothing...
This means that I can only use both SIM cards in GSM mode which sucks. does this anyone else has this problem? or any hints?

WCDMA problem

I'm having this issue with WCDMA in which it constantly drops to 0 signal bars from full signal, and sometimes I even get disconnected from the network until it decides to jump to full bars again. This happens on all locations, ROM is stock XXLSC deodexed (got it from the user I9000 here in the General section) and the problem just keeps repeating itself. Signal drops completely, then jumps back to full, then fully drops again after a short period..it's extremely annoying since I can only use the slow GSM network, which is useless to me when I need fast internet. I called the network operator and they say they had zero reports on an issue similar to mine, so it's not them.

Maybe you should try another "modem" file or test another real stock Rom.
XXLSC isn't a stock Rom - it's based on the XXLSA leak from sammobile.com with the two OTA updates I got on my device. So it has bugs and you should see it as early beta.

after upgrading to JB i used to have similar issue.. loss of signal.. call quality issue.. i changed the modem to one for my location and it has improved a lot. You could try that too

My phone was recently in the repair shop because its usb port was busted up. Ever since I've got my phone back, I have this issue and the technician guys are baffled about what it could be. They just changed the connector and nothing else, I don't see how that can cause any issues with the reception. It keeps loosing signal every few minutes, only to jump back to full bars.

I'll just switch back to stock 4.0.4 and see if it helps, but I'm still quite sure that my phone worked fine with XXLSC leak for a long time.

Update on the situation......I gave the phone to the official Samsung service shop, they tried everything, from changing software to cleaning/changing antennae connectors, and nothing fixes the problem. Most likely I'll have to get the motherboard switched, which costs about 210 euros. Pissed beyond belief right now, would rather just throw the phone away.

Call problem when on 3g/h/h+

So, this is my problem... I have a regular international factory unlocked n7000. And when im in 2g+3g network mode(hsdpa+hsupa) my calls keep droping after a minute, couple of seconds- no significant patterns... I think it could be beacause of the network signal change (weaker or stronger signal- from h to 3g or 2g) . when im on 2g only everything is normal, no dropped calls...Curently im on PA 2.99+ rom and lsc modem , but even when i was on gingerbread and ics i had such problems... I tried different kernels, roms, modems...
I even had that issue on my i9100...
Does anyone else have similar problems, and a possible solution?
