Mobile internet - Galaxy S III Q&A, Help & Troubleshooting

Hi, i writted CM11 to s3 and I cannot use my mobile internet. I can use wifi without any problem, also I can use my mobile internet to PC via usb. Any solutions?
Tried to reinstall and update CM11
CM installed from stock 4.1.2

You'll probably just need to find your mobile providers APN for data and put that in, your provider will have the manual details. Usually the sim carries this information, perhaps sim toolkit may also have a feature to set this up.
And yes you can tether your mobile internet whether it be wifi or data:
-Install Samsung usb drivers. (if you haven't already, or the kies program)
-Plug in phone.
-Settings/Wifi/Wireless & networks area - More/Tick USB tethering.
It'll then just work.
If the instructions aren't exactly as I wrote, I'm basing that on the location in Lollipop. It's in a similar - if not exact location in KitKat.

[Q] Ad-hoc network problem

Hi everyone
I have a galaxy mini mobile, and I upgraded its firmware to android 2.3.4
I tried to make an ad-hoc connection with my laptop but the mobile couldn't detect it.. I knew over the internet that android doesn't support ad-hoc connections
And found many methods to enable it, but they were for earlier versions (as 2.2) and tested on another models (mainly HTC)
I downloaded a program from the market but it didn't work and after removing it, the mobile stopped working
Now I have re-installed the firmware (2.3.4) and I want to know if there is any working (safe) method for allowing ad-hoc connections (knowing that my mobile is rooted)
& thanks in advance
Problem Solved using "Connectify"

[Solved] Saferoot, googleplay

Hello there users of xda,
After I installed saferoot I've notice that my google play stopped working via wifi connection but works on my 4g connection. No connection to google play via wifi, also while connected via wifi I've tried to download apps via google play on the computer. A notification pops up on my phone telling me the download failed. On the other hand if I am connected via 4g, google play on the s4 works just fine. I am a noob here.
I don't have much data to run on as I have already used half of it on pandora while going to work and returning from work (2gb data plan).
phone: Galaxy S4
Model: SCH i545 (if you can't tell already it's verizon)
Android Version: 4.3
Build: mk2
Root: Yes=saferoot + safestrap​
Never mind, I've solved the problem. The problem occurred after I've uninstalled abp (adblockpro). When I installed adblockpro, my proxy setting was changed on my s4, all I had to do was change the proxy setting back to the default settings.

Mobile Data Issue

I am unable to get mobile data on my Galaxy S3 SCH-R530 after upgrading it to 4.3 MJA base band as mobile is reading inbuild parameters of data instead of reading it via SIM and i have taken logs of modem file to figure it out but unable to get it. i set the apn manually but no luck. the mobile internet icon doesnt even show up in the notification bar. Tried restarting, factory resetting, even reflashing but no luck.Does anyone have any idea to figure it out would be helpful.

Multiple users and sim card

Hi, I have a sgp521, 5.1.1. Unrooted.
I use the tablet both in and out house, with an internet sim card, and i have two users (me and my sister), but when i try to connect to internet outdoor with my sister's user it says that there's no internet connection. It only works through wi_fi, and in setting it doesn't show the mobile Internet settings.
In users there's no option for this (well no options at all)
Is there a way to fix this?
I already tried to downgrade and root, but i can't find a proper firmware (italian firmware) and others firmware didn't work well, so i can't use this way.

Cannot connect to my home wifi (only) after accidentally blacklisting it

So, the weirdest thing happened to me... I installed an app named WiFi Connection Manager from roamingsoft to play around, and I asked this app to blacklist my home wifi.
I then asked to un-blacklist it, but that failed, and ever since I cannot connect to my home wifi anymore: when I insert password it lists my wifi as "saved" but it won't connect.
Things I tried that did not work:
change wifi name
change wifi password
change wifi channel
reset bits and piece all the way down to factory reset the phone, install a different rom* and go back to original rom
* more on that below
Things I tried that did work:
change rom to lineage OS
change rom from android 9 to 8 (both original android one rom from the phone brand) (but going back to the original rom version 9 fails again, even tho I flashed form a newly downloaded file with nothing to do with the version I did somehow corrupt, and before I even logged in to android, so the phone did not even know it was the same user)
change the security of my wireless from wpa2 to something else (wpa/wpa2 for example)
oddly enough if I change wifi settings to have the same wifi name shared between my 2.4ghz and my 5ghz wifi, my phone will connect to the wifi, and it will connect using the 5ghz (the problematic one).
---
i also have the feeling a corruption to my nfc happened at the same time, but I don't know for sure, in case someone knows of a connection between the two problems let me know, but the nfc never worked on other roms.
When I flash a new image I flash a number of partitions including one named bluetooth, so I can't imagine which partition I am leaving untouched that has the blacklist in it...
Does anyone have an idea how an app -even if it had root privileges- could cause such low level damage, and more importantly how I could fix it?
