Hey!
I started getting this after 6.0.1 update on my Canadian version (SM-N910W8)
Basically it shows data over mobile network connected but shows no signal for the phone part (see attached). Data is working fine but you cannot make or receive calls as well as SMS ain't working.
I reset the phone to defaults after getting OTA (well OTA wouldn't work for me so I used the new Samsung Smart Switch desktop app to update the phone).
Upon reboot everything gets back to normal and after half a day or so the above happens again.
ANy ideas?
Thanx!!!
Google your APN settings for your carrier and add it in to a new entry. Save, select then reboot.

Hello.
Just today, I have finally decided to update my nexus 4 to android 4.4. I downloaded the factory restore image from Google for 4.4 KRT16S, and installed it.
After reboot and setting up all my apps, I have noticed I'm not getting a data connection anymore. I was connected on 3G just fine a few minutes ago. What's going on?
If i open google chrome and try to go to a page, it says "Wifi and Mobile Data is turned off", however going into Settings -> Data Usage I see mobile data is turned on. I turn it off and back on again to no avail. I can see my phone number and make calls out just fine. I have tried toggling between 2G/3G. I have also tried checking the APN's and they are correct.
I'm lost. No matter what I do, going into Settings -> About Phone -> Status it is always showing "Mobile network state disconnected".
Is this a bug with 4.4, or what?
Edit: Fixed it! The problem was that in the shipped 4.4 rom from google, someone made a mistake with the APN's.
The default T-Mobile APN field was blank. I created one with the APN set to epc.t-mobile.com and immediately it started to work. The DASH is very important, as epc.tmobile.com does NOT work.
Hi all,
I have the samsung g900fd, the dual SIM of the Galaxy S5. So far everything is fine. Now I had to stay at hospital the last week, so even a week without wireless.
Midweek then suddenly a problem. Whatsapp gets no online status. Flight Mode on and then off again. Very briefly receiving the messages. Then directly offline in Whatsapp. Not even more then 2 seconds.
I changed nothing till the problems arrived. After that, I deleted WhatsApp and reinstalled it. By verifying my number, i get a system message "there is no internet connection".
At my home WLAN it works, but with mobile data the same issue again - no online status.
After that I tried to test the factory reset. No positiv result. Don't know what to do now.
The configuration:
G900fd currently back to 4.4.2 stock ROM (after issue I updated everything)
Whatsapp the current version
SIM 1: FYVE, Vodafone network only for SMS and phone (GSM) and the registered number for Whatsapp.
SIM 2: Mobilcom Debitel, telecom network for mobile data (LTE)
This has always worked as I said previously. Maybe someone has an idea what it could be?
Greetings, friends!
I seem to be having an issue with my Galaxy S5. Many times when I receive a message (via WhatsApp or Snapchat for example)
my phone does not show any notifications. However, when I open the app manually, it recalls to use it's mobile data and only then,
when the app is running, I receive all of the notifications I haven't received yet.
This does not happen when my phone is connected to my house WiFi. My phone can receive data from my mobile network,
and my data is always turned on, but for some reason it's shut down for most of the apps (if not all of them) unless the app
is running (not in background).
I have tested this without power saver mode and app power saver, same result.
Is there any way I can get my phone to enable mobile data at all times?
So I'll be able to get the notification the second someone sends me a message.
Things worth mentioning:
Phone model: SM-G900P, unrooted.
Firmware: Sam Mobile's stock Sprint (G900PVPU3CPCA)
Hardware version: G900P.04
Android version: 6.0.1 (Marshmallow)
Baseband version: same as firmware.
Kernel version: 3.4.0-7603580
[email protected] #1
Build number: MMB29M.G900PVPU3CPCA
My device was bought in Europe (in Russia), but I use it in western side of the middle east.
That means I cannot activate my device via my network (using the hands free activation).
Whenever I restart my device, the "activating your device..." notification pops out.
It retries 5 times finally it opens the "Activate this device" app (from settings) and it says
the activation was not successful and that I should contact costumer support.
I have already set up my network's APN with their provided settings and it is the one
I currently use. I tried changing the APN type to " "(empty), "default", "internet" but it doesn't help.
My carrier provides a 3G network. The phone always has some bars and it shows the 3G sign in the
network icon in the status bar.
My network mode is set to Automatic (although I've tried all of the others and it didn't fix it).
I don't have a roaming option at all... ?
I can use my phone properly to make phone calls in an average quality.
This problem started only AFTER updating to marshmallow using Sam Mobile's firmware (via odin).
Resetting my cache partition did not solve this problem.
I will contact my carrier and ask them, but I'm pretty sure it's something in the new firmware that prevents
mobile data without forced usage (or is unable to connect unless a request is forcing it to change network type).
Any help will be much appreciated!
Update: Even when my phone is connected to my home WiFi, it won't show the notifications before I open WhatsApp.
Could it be a firmware issue?
I am also having massive problems with the APN after flashing my G900P with ANY custom rom. Have yet to find a fix for this.
I have been going through a weird issue on Total Wireless. When I use Android 6.0.1 and below, I have no issues with my service at all, everything works as it should. The issue comes into play when I use any Android 7.0 ROM, be it official or custom. Outgoing calls/4G data are fine, but I cannot receive any phone calls or send/receive texts. The only way for me to be able to receive calls and send/receive texts is to dial out once. After this, everything works as it should, that is until I reboot. Then I it goes back to the partial working state until I dial out again.
The issue persists whether I am using CDMA/LTE or Global Network modes. I have tried every single possible combination of starting with a fully working 6.0.1 firmware and upgrading through Smartswitch, with and without a full Wipe performed afterwards, doing a full 7.0 firmware flash. The issue is always present, and I am not sure if TW has issues with Android 7.0 or if there is a problem with my account. Their CS is absolutely useless in helping me with the issue, and our chats always end with if I can make a phone call, then the issue is resolved. They don't understand that the issue is still present, but it only crops up after a reboot of my device.
I have tried 3 different SIM cards and they have deleted and re-added/reprovisioned my device/number to their system but nothing seems to help this issue. APN is the usual TRACFONE.VZWENTP. It's really weird that it happens on two separate devices that I activate with my mobile number.
My only thought as to what it could be is maybe some weird provisioning error with the number coming from Verizon. Total Wireless doesn't have any type of VOLTE capabilities on their network, yet I was able to use a rooted Note 4 device and activate Advanced Calling/HD Voice and I believe Wifi calling as well and use it fine on their service. One oddity I noticed is that when the phone is in the initial 'Searching for Service' state on a fresh boot when I dial out while connected to Wifi, sometimes I will see Mobile Network Type change to IWLAN, whereas it usually says LTE. After dialing everything works correctly.
Any ideas on further troubleshooting steps I can take? If nothing can be done, maybe there is some way I can have a boot up script that makes a ghost phone call to any random number and immediately disconnects so I don't have to remember to dial out whenever I reboot my device?
Thanks
I don't have a solution yet, but you're not alone. I have a stock G935V (running Nougat) with Tracfone service running over Verizon's network. Whenever I start up the phone, the phone will indefinitely remain in a "Searching for Service" status until I initiate one phone call. Then the network instantly switches to "Verizon Wireless" and everything works correctly for as long as the phone remains on.
A long phone call with Tracfone and Verizon yielded no solution: They indicated everything is configured correctly in my account. Various replacement SIM cards didn't change anything either.
This issue happens with both stock Samsung S6 phones and the Samsung S7 phone in my household. All are running Nougat.
Any update here? My girlfriend's phone has the same issue since moving from Verizon to StraightTalk.

Tracfone tried, half-heartedly, to solve the problem by sending me 3 different sim cards. The problem never went away. I just got in the habit of initiating a call to voicemail whenever I restarted my phone.
The problem went away when I upgraded my S7 Edge to Android v8 Oreo.
I have flashed the Nougat "U" firmware on my Verizon S7 Edge. I had VoLTE, hotspot, HD voice when calling someone on Verizon (but the HD symbol doesn't show on my dialer, only on theirs).
Only issue was that. when I introduced the TW SIM, the APN was auto set for Tracfone (and it wasn't working), so I had to manually change it to the TotalWireless one.
Since then I had received the Oreo upgrade and the following security update... and it's still OK.
Hello all,
Got my G955N in my hands. Followed the threads here to get TWRP installed, used it to install Batman ROM, then used TWRP to flash the AT&T CSC as my provider is AT&T.
In my pull down menu I do have the option for WIFI calling, however whenever I hit it, it fails (seems I can't post pics, so here is the text I get: "Loading, this may take a few moments" then it blinks a few seconds in and repeats. Then it goes to "Please try to set up WIFI calling again later."
I know it's an issue with my phone specifically because my wife's AT&T iPhone7 has WIFI calling working fine (not an ISP issue at home) and I swapped her SIM into my phone and I still got the same error. So it's something with the phone and not likely an account level issue (although maybe? Who knows at this point?)
Also, when I enter the testing menu, I see that "Data Service: Disconnected" which I'm not sure is right? Also, VOLTE Provisioned is not selected, however each time I do select it, it immediately goes back to deselected the moment I navigate away from the testing menu. I can reselect it all day and it still goes back to deselected the moment I move out of the screen.
I've read until my eyes bleed and tried just about everything I could find to try and no joy.
Any ideas?
P.S. got pics if anyone wants me to email them to you for clarity. Guess I'm too new here to be allowed to post pics
To follow up:
Turns out it was an account based issue. Seems AT&T tries to verify the IMEI when attempting to use Wifi calling. So unless registered in the network, it isn't going to work.
And the kicker is, AT&T won't allow Wifi calling or other services with any phone they didn't sell. You can toss in your SIM and use calling, but they won't activate other features if you try to bring your own phone.
So I spent yesterday switching to T-mobile and am now fully functional with all the features of my phone working as they should. AT&T lost me as a customer.
