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.

Hello i need help about 4g.
i Bought sm-900i from u.s this summer. i`ve been told that this device has 4g lte,(also on spesifications in internet and back cover has lte logo) but i never saw that option and cant use it why ?
Right now im living in lithuania and the operator i use provides 4g from 800 , 2100 ,2600 only 800 is not supported by my device.
On options in the phone when i go into the settings in phone under mobile i cant see any LTE on network mode only 2g and 3g which i attached the photo what may be the problem please help.
Can someone please help ?
help please
If that model S5 100% supports 4G, then the problem is with your carrier/provider or coverage

Have you tried to change nertwork mode to WCDMA only or GSM...or both WCDMA and GSM...????
Hi bro I am from Pakistan too so I research on it (couz I got 4g phone as well) I tried zong and didn't received signal so what I found is that these networks are on limited bands to work u need both phone and network to be same frequency supported to work 4g (and don't ask me how to do it couz I don't know either) try using warid (if possible) 4g it probably gonna work (not sure) or maybe you are not in 4g coverage area....
