Hello xda ,
I have a problem with my i9505 .
I have no gsm signal.
When i choose "GSM only" it says "emergency calls only" , thus in the areas without 3g , my fathers old brick is better than my s4.
If i chose "WCDMA only" it works in the areas with 3g .
If i choose "WCDMA/GSM" if the 3g signal is weak , it search for 2g... doesn't find so i get again "emergency calls only"
If i choose "LTE/ WCDMA / GSM" and i try to call somebody it brings up the calling screen but nothing happens until i get " line busy "
I tried a lot of different modems with no luck , my google skills failed me too ... so here i am .
Any sugestions ?
PS. No waranty here. So " send it to samsung " is not what i'm looking for .
Thanks for reading.

Hi experts,
Very frustrated with the SGS phone GT-I9000 I bought a week ago. I keep getting "Data network not available" while trying to make merely voice call (in area with poor signal).
However, I have no problem making call using old Nokia phone with the same SIM card.
The GT-I9000 was upgraded to Froyo 2.2 (DXJPE) lately.
Anyone encountered similar issues? What's wrong with this Android phone, modem issue?
Regards,
Void
That new i would return to seller and get them to check phone under warranty .

i got the same problem after upgrading to froyo, im from Panama, but i flashed my device following some UK guide, so i flashed it with another CSC, so if you did so, we both lose our network settings, so you have to set up the APN manually.(thats what i read) but i did so and i still cant make calls nor receive 3G
It happens on EDGE. Make sure you've selected the network to operate in WCDMA only..
Switch the Wireless and network -> Mobile network settings -> Network mode to "GSM only" or "WCMDA only" but doesn't resolve the issue.
However, I notice when the problem occurred, the Setting->About phone -> Network showing "Unknown" but the Signal strength seem to be OK, fluctuating between -87 dBm 13 asu (with 4-bar) and -111 dBm 1 asu (2-bar )
Probably, SGS transceiver/modem is not as good as Nokia E71.
Anyway, I guess I can only use this "smart" phone in city area.
in my case the problem was the orange phone card. i have changed it.
Hello,
I have a problem with my Galaxy S4.
When the mobile lost the 3G signal, at home for exemple because the signal is poor, the mobile shows the "no signal" icon during 10-30 seconds in the status bar before switching to 2G signal.
For me it's not normal ; because when a mobile is in 3G mode, it has to listen 2G cells for a rapid switch in case of 3G poor signal.
I tested the transition 3G -> 2G with my Galaxy S2 and there is no problem with this mobile.
Anyone has the same problem with the Galaxy S4 ?
Thank you.
same happening here for many others too... please check this.. though there is no absolute solution to it..

Hello,
I have a huge problem with my Galaxy S5 SM-G900F. I bought it abroad and when I used it for the first time in my country I saw, that there is a problem with 4G/WCDMA connection. When I put my sim card to the phone and set all the preferences in mobile connection menu to "Auto" there is no possibility to call or to recieve calls (even if i saw signal strength meter showing some marks). I can only recieve and making call when I set "only 2G" option and manually select my network. But signal is also very poor.
What I have checked yet:
1. Other sim also doesn't work good.
2. After *#06# i saw my IMEI and it is the same under the battery and on the box (doesn't start from "00") so i think that it is not missed (efs folder).
3. Change firmware with KIES and ODIN for the other version - no changes. Also flash some other "modem" files with Odin with no success in better signal.
4. When im on the free air the signal strength is even at maximum level, but immidiately after going to my house - there is no signal. I saw also, that when im in the city i can connect with 2G network (only), but when im on a village there is no signal at all (even 2G...)
Do you have any ideas what can be wrong? Is this hardware failure? Maybe something with antenna? What should I do before going to gsm service center? Maybe i should change kernel and try some of the custom roms?
Thank you for your help.
regards
Mario
