When im at home- in certain places i dont get any network signal. But i can see that the Sim Card is inserted:
Now, when i was trying to isolate that problem and i start to think what kind of problem it is exactly. If it is software (Android version or modem- ill burn ROM on it and so) or Hardware problem (in that case i will buy the network housing or the part i will need to buy to fix that) but i cant get determin what cuase that exactly.
Can you please help me to solve this?
My phone details are:
I also have the infamous Knox void enabled to 1 (Samsung dont have real warrenty or support if that matter) but i dont think this is the cuase :
By the way, my wife have the same phone with the 5.0.1 android version and she can get full Network and data network all ove our home or outside. Anywhere.

Problem with 3G in TD2

Hello,
First of all sorry for the bad english.
With my old sim card was broken i get a new one. With this new card i cannot make the 3g symbol visible. There is allways the E (edge). I'm unable to make video calls. Only normal internet connection with edge.
The operator call center guy said that my 3G is active.
Well i hope you understand my problem clearly.
How can i solve this 3G issue?
Thanks for any help.
You can see some screenshots below.

3G maybe active on your account and your old sim card, but it also needs to be enabled on your new simcard. If you speak to them again, make sure they know you have a new sim card. Even provide them with the simcard number and they can lookup on the system if its 3G enabled.
Thanks for your reply.
They know the situation that i have a new card.
I will move my number tomorrow to vodafone. I'm tired of this stupid people and their gsm thing. I really hated them.
Imagine: nobody there can help me about the WM phones.
I don't know how but i finally managed the 3g connection. It's an H symbol now. But this time my internet connection is missing. I can't connect to msn nor an http with explorer.
Any idea?

[Q] Galaxy S4 LTE (i9505) connection issues...

Hi guys,
I'm using the Google Play Edition ROM for some weeks now and noticed something strange.
I have one of the best ISP's in my country (Belgium) which has almost everywhere 3G and on the most places even 4G. In the past I had very good 4G signal almost everywhere with my HTC One but with the Galaxy it's always stuck to 'E' and very occationally I get 'H' or 'H+'. But let's say for the most part, like 90% of the time, I only manage to receive 'E'...
The specific ROM:

}
As I'm not allowed to post in the development thread itself, I thought I could ask it here...
I already tried setting different connection types:
but none seem to work like it should. Or they work but I keep being stuck in 'E' mode...
EDIT:
I also tried using the 2 different kernels, but no change.
Another thing I noticed, when I'm on the phone with somebody I can hear them clearly but they all say my connection get's disrupted and they can't hear me (or not clearly) but the connection stays present.
Thanks!

Stuck with Fake Note 4 Wont Connect to Network

So unfortunately my gf got scammed with a fake note4 not realizing there were fakes floating around Shes ok with owning up with her mistake and using the phone for the time being. (I've ordered her a new legit Note4 and should be arriving next week)
The phone seems pretty ok despite the knock off os; I would like to play with it and see how it pars up with the real thing but the damn thing wont register to the network. Every time I try to place a call it says mobile network not available; now it doesnt say not valid or blocked but after some poking around found that the IMEI doesnt match whats printed on the sticker in the back, could this be the issue? I am in Canada and carrier is Fido/Rogers.

Thigns Ive tried:
-factory reset
-checked apn settings
-disable/enable network settings

What might be causing the poor network issues on my LS980?

I have an unlocked LS980 (on CloudyG2 3.3 Lollipop 5.0.2, Dorimanx Kernel 3.4.111, and Baseband MPSS.DI.2.0.c2-00081-M8974AAAAANAZM-1). Am using it in Kenya. My phone loses 3G signal (on the Safaricom network) the moment I enter my house. I have to switch to 2G everytime I arrive at my place. Thing is, I also have a USB HSDPA dongle I use with my desktop computer on the same Safaricom network. The USB dongle reports a 3G signal strength of -76dBm

. My phone, on the other hand, (am holding it less than a foot away from the USB dongle) can't even register a very weak -113dBm signal. It just presents me with an "Out of Service" message
. I would really love to know what the problem might be, and if there might be anything I might to do remedy the situation. 2G just sucks.
You can change signal cable (black one). Probably there is a problem with it. This cables are too weak, be careful.

you need to take it to a repair store and ask him to reball the baseband
