Cannot reconnect to mobila data after temporary network loss - Xperia Z5 Compact Q&A, Help & Troubleshooting

It happened twice in last 3 days. I went through a small no network area (in the mountains). After I come out of it, I got the network back but not the mobile data. I rebooted, I checked the settings, I took out and reinserted the sim, nothing. I went to a network sales point and they had to reboot my data settings or something in their system and told me there was nothing I could have done myself. Right, I guess **** happens. Well, it happened again after 2 days and I was really annoyed. I called customer service and they said it was because the phone doesn't know to keep looking for data connection (so it's the phone's fault) and said I needed to turn it off and keep it off for 1 minute, then turn it back on and it will find the data. Which it did. However, I cannot afford doing this everytime I lose the mobile data connection. I found some threads about the Z and the Z3 series with somewhat similar issues. Does anyone know of a more permanent fix to this? If it happens again, I will honestly throw it on the ground, stamp on it a couple of times and get another phone. Even if I love the compacts.

This worked for my Z3C. I have not had to use it on my Z5C.
From reddit user FishStik5: Going into the APN settings and changing the APN protocol to iPv4 only (it was iPv6 before) seems to fix the problem.
How to find the setting: Settings-> Wirelessa and Network / more -> Mobile networks -> APN -> T-mobile data -> APN protocol -> Set to IPv4.

Anyway to disable data conn on phone?

I leave data conenction off, but somehow I'm still using data from time to time. I don't have an unlimted data plan and so any usage is to much. I'm running dcd 2.3.2 vzw. I'd rather not disable data via VZW network in case I need data but normally would never use it.
Anything I can do to disable data connection on phone to stop completely any data being pulled OTA and be able to enable when/if I need it?
I use my wifi so I'd still want that to work, but this shouldn't be affecting my data connection, right?
Thanks everyone in advance?

What I did was go to settings, connections, connections, manage existing connections, data network, select data network, then edit, Next, delete #777 and then enter 1 then hit next, and finish.
From then on it will show you the login screen but cannot connect.
Hey man, I had this VERY issue with my xv6800.... You have 2 options.... You can call every month and ***** that the phone automatically connect and uses data by itself, which it does.... or you could delete your data connection setup but this will disable your MMS.... There is nothing on their end they can do.... I went thru this just like you are... SUCKS.... I ended up getting the unlimited data plan because: A) it allows me to game at work, Corp network is firewalled for the ports I need... B) FTP ports are also firewalled so I use the phones data.... works excellent.... I had to have them take 111 bucks off my bill the 1st month because the phone used 6.7 megs in 2 weeks by itself, then I got the 24 dollar 10 meg data plan, but when it went to 10 megs and I still had 2 weeks left to go, I called and had them add the unlimited plan..... My bill would have been 1400 bucks without the unlimited plan..... So now I USE THE CRAP out of the data side..... screw em......
You could also call VZW and ask them to put a DATA BLOCK on your account so that no matter what your phone will not be able to use data.
I deleted the data password (vzw) on my phone so whenever it tries to connect it asks for the password. I also changed the default "for programs that connect to the internet" to use work network instead of the data connection and then setup my mms to use the data connection to pull pictures from. I only use the data side for mms and wifi for everything else.
Cool - knew I wasn't the only one with this issue.
Thanks for all the suggestions. I'll see about getting vzw to credit me and I'll turn off the connection by changing the #777 or password.
Thanks everyone for your suggestions.
You can disable your connection in the registry. On the flip side I set mine to "Always on" in the registry.
Try this

I use an app called "NODATA" you open the app, select your "CDMA1X" or what ever and toggle it off. you can toggle it on when you need it by opening the app and selecting it. I don't have the link but I found it here. So you shouldn't have any trouble.

I've been using that program for a year now it's easy to use no need to keep entering ur password with the #777 method or having to edit ur registry everytime u want to go online... I live on US canada border and roaming charges were killing me first 2 months I had this phbone because it would bounce back and forth between verizon and telus... this proggie saved me tons of cash and hassles with telus... well worth the download
Completely disable 3g data connections forever, save wifi
This is my first contribution to xda-forums! I'm glad I can help at all when I've benefitted so much... Thanks to all!
NOTE: After the following steps, Modaco's Nodata doesn't even register that a data connection exists! For this reason, if you occasionally use 3g, you probably will want to use Nodata, and NOT the following solution. You just might have to open Nodata and disable the data connection every time you soft-reset.
I was finally able to completely 100% block the 3g data connection on my Verizon XV6800 (aka Mogul aka Titan) was the following three steps:
1. The key culprit is HTC_CM_Guardian.exe in the windows directory. I couldn't edit it or delete it via Total Commander file explorer, but I was able to rename it! This makes the OS unable to find the program when it tries to re-set the Data connection settings.
2. Under Settings > Connections > Connections > Advanced > "Select which networks are automatically used," hit "Select Networks."
3. Under "Programs that automatically connect to the Internet should connect using:" hit "New...".
4. Enter any name you want (mine's "nodata!") and leave all the other settings blank.
5. To be safe, you may have to delete the Verizon Or "Internet" Connection on the Tasks Tab of Settings > Connections > Connections. Save and exit.
Voila! Wifi, yes; 3g, no! No more nasty billing surprises.
Modaco's Nodata program is awesome, but the problem was that HTC_CM_Guardian.exe re-enabled the data connection every time I reset the phone. Plus, HTC_CM_Guardian.exe would also thwart any effort to block data via the "Connection Settings." By renaming HTC_CM_Guardian.exe and creating a "nodata!" connection that programs auto-connecting to the internet would try to use (and fail), we get three results:
1. Modaco's Nodata doesn't even register that a data connection exists! For this reason, if you occasionally use 3g, you probably won't to use this solution.
2. When you reboot, the OS is unable to mess-up your "Connection Settings", so
3. Unless you have an active wifi connection, programs will try to connect to the Internet using the "nodata!" settings, which, being empty, will fail, exactly as planned.
Hope it helps.

[Q] Connects to mobile network even when wifi is available

Hi all
Not a power user's dilemma I'm afraid but I hope someone can help me out...
What's bugging me is that my wife's LG-P500 incurs a small charge every day because, despite all the settings telling me it should NOT connect to the internet via the mobile network at any time, it somehow still connects - even when wifi is available like at home.
This wouldn't be a big deal normally but because she's on a pre-pay txt only plan her credit gets used up quickly.
My HTC Wildfire uses NO mobile connection at all when I have wifi available. Any ideas why this should be happening with our LG-P500?
Great forums by the way and I'm slightly embarrassed to be raising this probably noob topic here but I can't find an answer anywhere else...
Thanks in advance!
I haven't seen that problem on my P500, with the void echo ROM (the stock firmware didn't stay on the phone long enough for me to try that).
The option to disable it is in:
Settings -> Wireless and network settings -> Mobile networks -> Data enabled (should be unchecked)
Or in the drop-down menu of the notification bar.
I'm not sure about the stock ROM, but on void, an additional icon appears on the notification bar whenever the mobile network is active.
You could also try disabling the option:
Settings -> Accounts & sync settings -> Background data (should be unchecked)
Thanks. I already did all the obvious stuff you mention, having seen it work fine on my Wildfire... Any other ideas out there?
Might this be related to Location Services using Cell tower information ?
Could try turning that off anyway.
If you don't want to use the mobile network for internet access, than go to Settings > Wireless & network settings > Mobile networks > Uncheck Data enabled .
If the network allows you, you can also select Network mode > GSM only, this will also save you some battery. For example, I only use wifi to connect to Internet on my phone, and I also checked the option "Use only 2G networks" (also saves battery), I'm connecting to my operator only for phone calls
What is your Wi-Fi sleep policy settings? Try setting it to Never.
When the phone goes into sleep mode, wifi is turned off to save on battery. May be that's the reason mobile network is getting connected in sleep mode. If u enable wifi policy to never sleep that will drain the battery. You can disable the mobile network from th3 notification bar that should help.
Many thanks for the help guys!
Wifi sleep: good idea, I'll look at that!
Location services: good idea, I'll look at that!
Data enabled: unchecked already.
The problem still strikes me as odd because although I have ALL the same apps (and quite a few more...), I don't have this problem with my little HTC Wildfire...
Update: the only way I could find to resove the issue was to invent and use a nonsense APN...
Wifi sleep was already ticked as "never" by the way.
Thanks again everyone who gave advice.
Yeah, I've also had reason to use an APN named "fake" with a proxy named 'fake", although i use "Z" now to save typing, LOL.
This is one of many things i would do when changing SIMs. I have had one SIM and phone that always set a new APN and this ended up costing me a few bucks in data fees before I re-changed the APN info.
I would also disable the data services, make sure WiFi was on (to provide priority data access) AND enable airplane mode.
Anyway, your experience has inspired me to check more deeply about my data usage. I don't like the idea of my phone doing data without my knowledge while it's in standy.
I prefer to manually choose which connection I would like to use, so if I'm using my data plan such as when I'm out, I go to notification and enable data. I only get 200mb a month so its easier for me than to always keep networks on even when I'm not using them. It also saves on the battery as well.
EDIT: you can check your data usage using 3g watchdog app, find it in android market
It easy to solve. Just install APNdroid

It also has a widget. Works very well.

HTC Titan Wifi/3G and Live services

I've spend over a month trying to battle the issues with not able to use Live services and Marketplace over the 3G connection.
I've been back and forth with plenty of hard resets adviced by Zune support - no change.
I've been back and forth with plenty of hard resets adviced by WinPhone support - no change.
I've even swapped SIM cards - no help.
Issue:
You can't download apps/music or stream music using 3G. On wifi it works fine.
Reason:
HTC WiFi bug goes deeper than we think. It's not just being or not being able to run 3G and WiFi together or low WiFi signal. But if you at times try and download or ugrade using WiFi and use 2G mode at the same time - you will get this. As soon as you switch from 2g to 3g and switch off wifi - nothing will download off your marketplace.
Solution:
I've reproduced it many many times. However, it will only happen if your SIM doesn't have APN settings on it i.e. non-contract phones using certain pay as you go networks i.e. Tesco, Lyca, Giffgaff, Talktalk
When you go 2g/3g swapping and use wifi - the phone forgets your APN settings. Once you switch to 3g, go to APN settings, edit your password by writing your password again and save it. Restart phone. Now your 3g will work again. You have to do this every time you use combo of wifi/2g or sometimes even when using wifi and then switching to 3g.
Moan:
I've contacted HTC, they don't care, they think it doesn't exist. They want my phone to be sent for repairs. I am not doing it as I have only one phone. I know HTC won't even acknowledge the earlier Wifi bug. But luckily we have workarouns.
Have you tried running the HTC connection setup to see if that resolves the situation in some way?
Sent from my TITAN X310e using Board Express

Yes I did that too. But HTC connection setup settings are forgotten as soon as you swap away from 3g. So everytime I come back to 3g, I have to re-fresh my APNs manually and restart! - such a pain.
thanks....

Wifi network "Disabled"

My wife and I are having the exact same issue which started within the past 48-72 hours.
Our phones when returning from say "Sleep mode" will not be on the wireless network. When you look at the networks listed, it shows the network as disabled. No other devices are seeing this issue, laptops, nexus 7's, SGS4, Galaxy Tab 3, etc.
When we click on the network we can connect and things go back to normal temporarily. I've restarted the router, I've restarted the access point, the phones are assigned static IP addresses which do not interfere with anything else on the network.
Nothing on the network has changed in the last 48-72 hours.
I've told the phone to "forget the network" but still see the issue.
I've also factory reset my phone and restored from a backup to try to resolve this.
Any ideas?
Still having this issue.
Just as an update:
Finally gave up trying to troubleshoot myself and went to a Sprint store. The technicians at first tried to say that it was my network, which I quickly shot that down by saying both of our LG G3's are having issues and no other wireless device has an issue. And there's about 10-12 other wireless devices at any given time on the network.
I mentioned that it's showing up in the Sprint forums. That's when the technician looked into their online db (or maybe just the Sprint forums). After a few minutes of a perplexed look on his face, he said... "Oh... that's not good."
Apparently, this is becoming a very common issue with the latest update ZV8. So he'll be talking to his boss about what they need to do next and will hopefully call me tomorrow.
I'll update the thread with any new info.
So just to let everyone know, the problem seems to be resolved now. Without going to Sprint or replacing the phone.
The problems apparently had something to do with the statically assigned IP addresses that I gave to the phones. I have not made any changes to those static IPs in months so there should not have been a sudden issue with them, however after removing the static IP assigned to them, the phones seem to hold their connections just fine.

So it's not a common issue with zv8?
Did the rep call you back?
And these static addresses I presume were on the router? Or were they manually set on the phone/device?
This might very well be a common issue with zv8.
The rep never called me back. Although this is sprint that we are talking about.
The router assigned the static IP addresses.
Pfsense router if you are wondering.

Android phone connecting to internet through mobile data even with Cellular Data off?

Greetings,
I own a OnePlus 5T (128GB) and I am running stock firmware (OxygenOS 5.1.7), rooted and bootloader unlocked. I traveled to a country for which I have a local SIM for, but didn't have (yet) any data plan. What I did to prevent unexpected charges was disable mobile data immediately (I did the same to my wife's phone, which is on the same ISP), so that I could receive phone calls and SMS, but I won't use internet and obviously I won't make phone calls or send SMS.
What happened next is that my phone connected for 0 seconds to the internet every day at a random time during the day, triggering a 6€ expense for 10 days.
I searched through the data usage log to see if any app used internet, but it was empty.
Interestingly, my wife didn't get any charge, so I presume that the configuration I used to prevent access to mobile data was correct (it displayed an X instead of 4G+ over the chart showing the mobile signal strength).
What I'd like to discover is what caused the charges (I did get a refund since those connections lasted 0 seconds each), to prevent this from happening again. However, the phone has been completely unhelpful. I do have a data plan now, in case it's needed to perform some tests.
My best guess so far is AFWall+, it's the only application I can picture bypassing the "cellular data off" option. Those connections looked like DNS connections also, due to how short-lived were.
Any suggestion over how to diagnose this?
Thanks for your help.
