[Q] Mobile data connection problem

Hi
I was wondering if i can find help here as all other sources failed
I will try to describe problem as detailed as possible but I'm newb when it comes to android so please be understanding
I'm Samsung Galaxy S4 user, just stock model I9505 running Android 4.4.2.
Using WiFi phone is completely fine but when it comes to mobile data there comes the problem..
I can use internet, browse small websites or use hangouts/fb messanger but i it seems outgoing connection is slow or none.
It happens at random and can last for 1 or more hours.
When i take seedtest, download is fine at 4Mbps but when it gets to upload app stops until <force close>.
Something is wrong with outgoping bandwith.. Ive tried to set up APN manually, restart, clear cache etc nothing works.
Ive been on the phone with operator and they said its all fine on their end.
I'm on unlimited Tmobile 3g tariff.
Anyone faced similar problem or knows how to solve it?
i appreciate any help

I can't recieve calls or SMS when connected to WIFI. S5.

Hi
I have just upgraded from a galaxy S4 to S5 and I'm having big problems with receiving calls and SMS when I am connected to my home WIFI connection.
Only when I turn off wifi on my phone I start receiving the backlog of SMS messages.
It's driving me mad as I have searched the internet high and low and lots of people have the same issues but no one seems to have a solution.
Some times I can receive calls when connected to wifi but the SMS messages don't come through until I disconnect.
My wife has also just upgraded from a s4 to s5 but hers appears to be ok.
I have noticed that in more networks/mobile networks/network mode, my wife's gives options of 3G, 4g etc but mine says LTE/WCDMA/gsm which I though was strange as we are both on virgin mobile. I don't think this is the issue though as it's a wifi issue.
Please help I'm on the brick of selling it as it's driving me insane.
Cheers

1- Regarding the WiFi issue, it may be due to some installed apps (a), some incorrect settings (b), or the firmware itself (c).
(a) Check to see if there is possible app that may cause the issue and try uninstall it.
(b) Compare with the S5 of your wife and make sure all related settings are the same. Or you can do factory reset.
(b) Try to update to the newer or latest firmware (compare with the firmware on your wife's S5), that may fix the issue.
2- Regarding the difference in the Network Settings menu, it may be due to different models. You can compare all important info on your own S5 and your wife's S5 with this app: Phone INFO ★Samsung★

Friends of mine were at my house over the weekend and he had a samsung s4 and had the same problem after logging onto my wifi. It is the wifi causing the problem. I had an old modem and netgear router that we hooked up and then we were able to receive calls like you should. We switched out the modem/router combo on Sat to my older setup and my phone is still working normally! I called my dsl provider and told them about the problem as I just bought the modem/router combo from them recently.
They never heard of anything like this. I do find it hard to believe that the home wifi equipment disrutes the cell phone signal. But my phone is now working!!! Anyone ever heard of this or that can explain why this would happen I would love to hear about it.

[Q] network problem (very strange)

Hi guys, first of all i made searches and etc. and found nothing, this is very strange issue,
i have an s4 (I9500) and cell network is not working well. in E mode (i mean 2G) all internet voice and texts are working as should be.
in combined mode, if internet open then no network, or sometimes E with data but no 3G anyway. when internet disabled all is good.
in WCDMA mode, if internet is open, then nothing no internet, no voice no text. when internet disabled all is good again.
strange thing is i can use 3G very different way.
check 3G or combined mode first
make a call
after connected call open network data ( internet)
in a few seconds i have 3G internet. but if call ends no data again and after while no network either.
for troubleshooting in 3G mode before signal lost i see H or H+ sign on my phone but only up arrow shows no down arrow i think that mean 2 thing
1- i send a request to carrier but no returning
2- i cant send a request but phone try to send.
it was the same in 4.4.2 firmware, now i have 5.0.1
i try to patch modem with other firmwares modem files but i could find only 4.4.2 modem files. and tried all of them but no luck
so i want to use 3G mode, my phone has warranty but glass broken and in my country it is avoid warranty.
i have no box jtag or z3x box only have cwm mode and odin with usb. so is there any solution to my problem.
my phone info :
Android version: 5.0.1
Baseband version: I9500XXUHOD4
KERNEL VERSION: 3.4.5-4727708
Build number: LRX22C.I9500XXUHOD4

Factory reset your device then. This look like hardware problem anyway

I already tried that too, factory reset, clean to install New rom, and no luck...
Looks like to me software problem too but i cant fix it.. Thats why i choose title as strange i dunno what to do now..
I think im having the exact same problem, it has been like this for the past 3 months. Unable to find any solution. Tried pretty much everything. The problem started 3 weeks after I installed cyanogenmod. Flashed back to stock rom but it didnt fix it.
Let me try to explain it:
I ONLY got internet + a normal cell signal when im on GSM mode.
As soon as I switch to WCDMA - WCDMA/GSM or LTE/WCDMA/GSM I dont have any internet or a cell signal, leaving me with the only option which is GSM, but that gives me Edge internet which is really slow.
The things I tried so far:
- Different ROMS
- Stock ROM
- Updated my APNs manually and automaticly
- New sim card
- Opened my S4 to check for any damage or water damage, everything looks fine!
I tried my SIM card in my friends phone, I got perfect 4g then.
Im starting to believe its a hardware problem

I337 Unlocked was getting 4G Data with no issues, Now I only get 2G/EDGE?

Hi every one,
As the title says I've been using an Unlocked i337 with Simple Mobile carrier for the better part of a year now with zero issues, and happy with my 4G data working fine for a very long time until today when I seen my phone was only showing Edge data with the "E" indicator. I have tried searching and troubleshooting it, and nothing comes up. I recently rooted but 4G data was working just fine even after root. I have checked APN settings and toggled off and on. I went into the test menu and GSM/LTE is selected. I don't have any option in the settings menu to turn 4G off or on. What seems to be the problem?
Also for the record I have called Simple Mobile customer service for help but they can barely understand me let alone help me but they did check my account to see if any thing got adjusted and they resent OTA signal to my phone and every thing checked out fine. They just kept telling me restart my phone about 10 times.
Model: i337
Android Version: 4.2.2
If I haven't included any other crucial details let me know. Thanks

Try settings - network and internet - mobile network- advanced - set preferred network type to Global.
That should help..
