Australia S5 Internet 4G playing up since coming back from holiday

I have an Australian S5. I went to England for 2 weeks and used a UK SIM card. All was fine.
Since coming back to Australia and using the Australia SIM my 4G shows I have internet but to get the internet to work I need to turn mobile network off (4G disappears) then turn it back on again. Afterwards 4G works fine.
When I have the problem, 4G will show but there is no activity. If I try to check email for example the email app (default app) starts to refresh and then just stops like there is no new email.
When I was in England I had a notification that there was new software. I updated the software over the air. All seemed well.
The phone is completely stock and not rooted. I haven't tried anything to resolve really.. except these two things:
- Rebooting phone - problem comes back after a while say 24 hours
- setting the APN. If I choose another APN, for some reason the one I was originally on is re-selected somehow. I don't know how, may be the provider has some control over this? I use Telstra.
Any help appreciated.

I've created a new APN and removed / re-inserted the SIM card but problem still exists.
I've no idea how to troubleshoot. Has anyone got any suggestions?

I fixed this over the weekend. It was the "restrict background data" option in power saving settings.. I turned that off. All good now. :good:

No 3G signal at all, but not quite the same

Hello, first to say, im not a newb, noob, newly registered, or a guy who dont understand anything from android.
Im not posting stupid topics, or topics which answers can be found easily on internet/google/xda/forums and such.
I am running stock rom, only rooted (i used to root it only to apply some xposed settings and clear some unnessesary apps, nothing more, nothing less).
Here is the description:
My phone has no warranty, i bought it online, brand new from UK, simfree. At that point, i had no problems with the connection. i received OTA Update - about 50-60 mb, but the phone remain 4.2.2 as it was. I still had no problems with the connection. After some time, the phone was left alone inhome for a few days, may be a week, it was turned off and it was not used at all. When i got back, i inserted my sim card, and i saw it is showing only G icon, and no 3g/h/h+, nor even 2g. I live in big city with very good network coverage, so its not network problem. I dialed up the customer service (Globul Telenor Bulgaria) , explained them my problem and asked them to check if its operator's problem or sim card problem, but it is not. The sim is fine, so is the network coverage. I dont have other operator's sim card to check the phone. I tryed several possible solutions found in google/xda - turned off the phone, removed sim and battery and left that way for few hours, still have the problem, tryed to switch operators manually and register sim card to other operator then back to mine, not working. Several times reseting/ deleting APNs, switching airplane mode, data off/on, adding apns/searching for networks and all available combos, not working asked Globul Customer support to send me new settings- not working. The only obvious thing i havent tryed is the factory reset (I still need to do a backup first and dont have time to do it right now.)
In Settings- More networks - Mobile networks- Network mode i have 2 options - 2g/3g auto connect and 3g Only. When I choose only 3g - i lose any signal, like there is no sim card. Reverting back to auto 2g/3g is registering my sim back to Globul network.
Then i decided to root my phone if i can find a fix for the connection. Rooted with CF-Auto-Root thru Odin. (The 30sec Root)
Looked for some tweaks in xposed modules and settings, i couldnt find anything related to 3g. Still looking for a solution...
I repeat - my phone was completely stock and non-rooted when the problem occurs! Now is rooted with stock rom. (this is the diffirent from every topic i searched.)
Im attaching some screenshots, if someone can help me. 2g is really annoying and slow as hell.

Well the first thing I would do is update your phone. You are running 4.2.2 which is old. Update to the latest version, that could either be a stock rom or a custom rom.
After that do a factory reset. Make sure you backup your internal storage etc, because it will wipe it clean.

Factory reset, updated to 4,3, after that 4.4.2 problem still persists.
No 3g at all. Its not the sim. Any way to fix it ?

Soo no way to fix it? Should i give it for repair?

Galaxy S5 G900P mobile data connectivity issue

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.

Can't call but data working

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.

G935V on Android N 7.0 issues with receiving calls/texts [Total Wireless]

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.
