Goodmorning to all,
I am Loris from Italy writing: I am new here and I am not sure I am doing right so, if I am wrong writing something, please tell.
After this I can tell you my problem: I bought a SM-G906K, Samsung Galaxy S6 Prime from Korea as you know, and I soon had problems while calling: if I am calling or receiving a call, sometimes soon, sometimes after some seconds, sometimes after some minutes, or sometimes it does not happen, I can not see anymore person speking on the other phone, but note: they can hear me.
I already try to call even with Skype, and it seams there is no problem: audio is ok even while reproducing video and so on. I tried making calls in emergency mode too, just to understand if some app could be bad, but I have the same problem, always and ony with calls.
What could I do? Please help me, if it is possible.
I am using a 4G Vodafone MICRO SIM card.
Best regards
Loris

Put your sim card into another phone and test to see if the problem persists?
That maybe the problem of the network, not your phone.

Goodmorning and many thanks for your answer: I already did that, I already changed 3 sim card too, but the problem is going on: with my old SIII all the sims are working as well. Maybe could something work wrong between network and the phone connectivity? From Korea they told me there would not be any problems at all ... but I am seeing it is not like that.
Anyway sometimes I can do calls of 5/10 minutes without problems...so it is strange it is a network issue, is not it?

I said that may be a network problem. As you have tested with another phone without problem, I doubt that is the problem with your phone.
Try to factory reset to see if it helps? If not, it maybe a hardware fault.

I meant maybe problem between this Korean device and Italian network: could not it be? Have anyone had any experience about this?
I already tried to factory reset by Kies many times but it does not help, and I noted that updates remained on firmware, they were not brought at factory state. If it is a hardware fault I think I'd have this problem with Skype calls too or other programs, is not it? Luckly, or not, this is the only situation I can not hear from the other line ... I really do not know what to do ...
Could it be it is the mark Olleh giving problems? Maybe using a G906 not K (I think this is properly for Prime Special Edition) but S it could work good: don't you think so? K and S are the same, is not it?

Call your WIFI provider and ask them to change the channel. Mine was set on AUTO and calls were delayed up to 4 hrs. When they changed the channel (to 11) my phone worked as it should. May not be your problem but something to try.

As the problem happens randomly, I can not tell exactly what may cause the issue.
Changing the CSC or flashing another firmware is a good idea to eliminate all software-related issues.
If you want to change the CSC, install Phone INFO ★Samsung★ app > Menu > Other Tools > CSC Changer.
(Note: That feature requires root to work).

Flashing the stock firmware and changing the CSC will not trip the Knox.
However, changing the CSC may need root to work. If it requires root, make sure to use a root method that does not trip the Knox.

Calls went to VM, the phone never rang. I wouldn't receive the VM for up to 4 hours later. Messages were delayed, I did not receive the message for 30 minutes from the time the person sent it to me until it finally showed I had a message.
I know it sounds crazy that the WIFI could cause a problem but it did.
Turning off WIFI on my phone did not solve the problem.
When I powered off the router/modem in my home my phone starting working correctly.
Something to try, hope it helps.

Galaxy S5 G906K
Hi,I have exactly the same problem and I can not use the mobile because of this.I leave in Cyprus and I can not hear the person who I try to speak with,sometimes in the middle of conversation,sometimes from the begining or I can speak 5 minutes without any problem.Seems like we have to make some setting for Europe inside in the phone with ☆#0011# and the phone to be rooted first?
This is a problem,if we rooting the phones we losing the warranty but it looks like is no other possibility to escape of our issue.How else?
Galaxy S5 G906K network incompatibilitty
Well,we found out what the problem is with hearing issue while calling.Is comming from the incompatibilitty of the phone hardware network and each country networks providers.Let me explain:Galaxy G906K Lte has only 3G and Lte(4G)networks build inside.So,if you are living in a country who doesn't have 4G install yet or not all over and instead have 2G and 3G only,and this 3G it does not cover all the areas,then when are you not in the 3G antenna area you"ll gonna lose the reception because this type it does not have 2G old GSM network build inside.That means we can not use it in 2G base network countrys.I hope I helped anyone who have this type of galaxy mobile phones.
Unfortunately I have understood you explanation, but before buying it I clearly asked to the seller and they made me sure the device would have worked as well: who told you such this explanation? What site did you buy the S5 from?
Many thank
Loris
Get this
Who told me this?Nobody, is very simple:go on Settings>More networks>Mobile networks>Network setting>RAT mode setting and you will see there Ltd network and 3G network,NO GSM network(2G).So,all the mobiles from Korea are for Korea and other country's which have 3G or Lte(4G)networks.For example Korea have ONLY Lte network. That's why is for Korea and this phone was named Galaxy S5 Lte-A. You must ask refund!

rooting will not kill your network connection. that's something that you did. you need to provide a LOT more information in order to have people help you out,
what ROM are you on, what settings did you change, what mobile carrier are you on, etc. etc. this is a simple fix, but we need to know what caused it first. :good:

Well the person above me said it. You just made a mountain out of a mole hill by giving out your imei to everyone on xda. Anyway, have you tried a factory reset? If that doesn't work take it to Best Buy and tell them Kies wrecked havoc on your device and they can re-flash your phone for free. Don't tell them it was your fault.

I don't know what the problem is but you should be able to flash the stock firmware in Odin and get your phone working again. Double check this in the i9500, i9505, i9505G S4 forum. You can get the stock firmware from sammobile.com

He should be able to flash it himself. The i9505 is not locked down like the i337. It's an international version so he probably can't take it to best buy, which is what I was responding to.

Data enabled, but no internet connection
Hello,
I have the stock rooted i337 (AT&T), running on another provider network. I am aware that i337 is very difficult to do modifications due to the built-in by AT&T vicious locks to prevent using it with other network providers. This is the reason I did not flash ROM, because I am afraid to get my phone bricked and lose it entirely. Recently I subscribed to a data plan from a third party provider and I have 4G in the status line and HSPA in the data type, but I still did not have internet connection when WiFi was disabled, except that my Hotmail somehow worked. No other apps requiring internet worked. I spent a week researching the issue myself as well as working with the provider's tech support, but nothing worked. Two days ago, almost out of despair, I installed a new app called Opera Max, which is developed to route the unencrypted data to their Virtual Private Network in order to compress it and save the data use. As soon as I connected to VPN, all applications started working. I still have to turn Opera Max off when I use WiFi, because it disconnects my WiFi every few minutes, claiming that WiFi signal is too low. (My signal is very strong and no other devices have any issues with WiFi). However, this is a minor problem, considering that Opera Max saved my data plan.
It is still a mystery to me why Hotmail worked, but no other apps and why using Opera Max VPN solved the problem. If anybody has ideas, I will be happy to hear.
I must say that all data settings, including APN are checked, rechecked and correct, so this was not the issue.
Thanks,
Dan
I am also having connection issues after rooting my S4 i9505:
I am on a Telcel (Mexico) which is supposed to support 4G connections... However, ever since I rooted I can only access 2G/GSM networks. I have the official APN network configuration and I have tried two roms but still no luck...
Any advice would be most welcome.

You need to swap the SIM card/the phone with another phone/SIM card to eliminate the causes from the SIM card/the subscription/the network...
After eliminating all causes from another sources, you can start to fix your phone.

My friend has the same problem. He was using Iphone 5s and I convinced him to switch to Samsung/android and he did . But so far its been problems for him on his S5 duel sim SM-G900FD.
I tried to fix it for him but no luck so far. Things I tried,
- Factory reset
- swap sim
- use only one sim
- software update from (XXU1ANF7) to (XXU1ANH2)
Last thing i am doing for him before I give up is to turn off the smart switch between data and wife. Other than that i'm not sure what to do. He always fix the issue by going to airplane mod then turn it off, but it will come again eventually.
Any help is appreciate it as i am trying to get a new guy into android world

1- Does this SIM works fine on another smartphone without any data connection problem?
2- Check the APN settings. Consult your service provider for the proper parameters.
3- Check for the baseband version? Try to flash another baseband...

I have a SM-N910C.. As you know it is not cheap phone. Since I use it as a business phone, I have constantly to have the transmission and reception of data and the Possibility of calls and sending messages and e-mails.
The problem is when I travel around the country, once and for battery saving, I constantly got internet. Almost all my country is covered with a good signal, except for some parts between the mountains ........
When I want to switch to the Mobile Internet GSM only, losing connection. I can only call emergency calls. I did a factory reset on the phone three times and nothing helped. I have replaced the sim card that did not help.

Some carriers decommissioned GSM services in favor of more modern 3G and LTE services. If your carrier decommissioned the GSM service, then you will not receive any 2G service even though you force your phone into it. There is not much we can do here if this is the case.

I apologize for not understanding your problem the first time. This is definitely a modem problem of your Galaxy Note 4. The modem that is inside your Galaxy Note 4 is either not recognizing the GSM band of the carrier or not recognizing the proper driver/kernel made for the device. I think the best way to resolve this issue is appealing to the carrier. Visit your carrier store and show them the problem(show how your phone is not connecting to GSM signals). Then, ask for an exchange. If that doesn't work, contact Samsung and ask for RMA and replacement phone to use during repair process.

From my past experience, flashing the kernel for the modem does not fix this issue where the modem itself doesn't fully recognize the kernel. However, you can try flashing the Poland stock rom which has the most stable modem package .so embedded.

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

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

Check the SIM Card and change it for one new.

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

Hello All.
This may sound like an easy problem to solve and a part of me hopes it is. but im fairly well versed in android and has me baffled.
Phone runs beautifully 870DS. When i leave WiFi, the swith to mobile data takes for ever and then remains super fickle and intermittent. I sometimes do not have any data moving whatsoever (offline dinosaur in chrome level) When i connect to wifi again, all is fine, instantly.
I have full signal (full bars).
Mobile data on.
Switch to mobile data on.
The correct network registered & the correct APN for that network is set.
I have it set to GSM/WCDMA/ LTE auto
I have tried setting RAT set to every possible combo and it still continues!
I read somewhere it could be caused by radio initiation, so i went in *#*#4636#*#* to run a ping test but "phone information" throws up an error "This application does not work on this device"
Im 95% certain it is unlocked because i I bought the phone in another country and just popped my new sim straight in without hassle.
The mobile data issues started almost immediately. Now im stumped as what to do.
Any suggestions would be greatly appreciated and rewarded with beer :good:
THANKS!!!
In Developer Options, try switching on the "Agressive WiFi to Cellular Handover" option.

Thanks. I will try that and trial run it over the next few days. The issue also occurs randomly while out on LTE or 3G. I will take my phone out to check google or whatsapp and nothing will send. So as your suggestion may be a work around, i doubt it will be a solve.
Will let you know how it goes

Does the phone have the right bands for 4G in your country?

go to settings, system, about phone, hardware info and check the model number.
For example I have LG-H870 (European bands, single SIM model).
I see you have dual sim so probably model H870DS and this should have enough bands to work well in Europe and Asia. Check here:

Thanks for that. Yes according to this https://www.frequencycheck.com/carr...0ds-g6-dual-sim-td-lte/mtn-group-south-africa
I do have the correct bands. Could a carrier lock only one of the slots rendering it single sim in effect? The one sim works perfectly, second sim, no dice
Sorry for bumping an old thread.
Gf is having a similar issue on her phone; long story short, it happens that sometimes, after being connected to Wi-Fi and turing it off, it takes ages for her to get a mobile data connection, despite having full signal.
I had her replace the SIM, as I've seen similar problems (intermittent data connection, phone appears connected but no Internet available, etc.) with a SIM card that was about to go bad; it didn't help. Next step would be a full phone reset.
@deathcells : did you find the cause of your issue?
@fagentu.xda
No unfortunately not. I just deal with it. Extremely frustrating standing in the shop trying to pay without internet...
I tried the settings and force options to no avail.
I tried using both sim cards (from different providers) in both slots for months and no combination ever worked for me. I have yet to figure out if i bought a dudd phone or if a work around exists. Please let me know what you find out! Thanks and best of luck
Have the same issue with mine now. It started to go bad a few weeks ago... Tried everything. Changed SIM card, factory reset, etc... and nothing will change.
I'd say that the phone is just faulty. As I'm still under the warranty I'm in contact with LG to find out about a possible fix or phone replacement. I'll try to keep you posted.
Have you guys find a solution for this? I cant do anything. Does flashing kdz to andriod 9 pie helps?
