Changing the starting day for Mobile data is indeed non-obvious. You need to enable the mobile data connection (2G/3G) before the options are available:
TURN OFF WIFI First.
Enable Mobile data.
Exit the Data usage settings app.
Tap the spinner below the Set mobile data limit checkbox.
Tap Change cycle....
Change Date of each month (I prefer the first day ...
First, that setting is enforced by the OS (so it's not for the app to decide whether to observe that setting). Put in easy words: Android won't let an app access the network unless it's running in foreground (i.e. the user is interacting with it) with the restriction enabled for it.
Explained with a plastic example: Restrict background data on the Google ...
I did not find a way to reliably do it without an app.
I often use OpenDNS Family Shield, but sometimes it blocks me to visit some particular hacking site and then I need to quickly and easily change the DNS servers.
I used to use Set DNS but it stopped to work in Android 4.3 and further, so I created Override DNS, a new app which mimics Set DNS' behaviour,...
This turned out to actually be a network provider problem (in my case: SimpleMobile in the US) and the fix is incredibly simple: remove the proxy server from the APN and everything works.
The final hint I needed was the Google Now error message, googling that took me to this thread on xda-developers.
I have no explanation for why 'clear data' fixed the ...
Somehow there was a proxy set up in the APN settings …
Edit: To change the proxy you have to go to the settings and click on mobile data. Select Access point names, select the active APN (or the one you're having problems with) check/reset the Proxy/Port settings.
No. You don't need a data connection plan to use OnePlus One or any android phone for that matter. Calling and texting will work irrespective of internet connection.
However, having a data connection will be useful if you want to use some apps on the go.
From the terminal, you can use svc to control several elements of your device. For mobile data, it would be:
To disable: svc data disable
To enable: svc data enable
You can simply type svc help for a list of available commands, or svc help [command] for a list of subcommands. For example:
To get the list of subcommands for controlling mobile data: svc ...
This has been happening throughout the world and is caused by a technical feature of 4G LTE. Most people don't even notice it because of the small amount of data that's used off their data plan. This is what happens: every time your phone receives or makes a voice call, it automatically switches from 4G to 3G mode due to the fact that LTE is a data-only ...
There is one hack by which you can block your incoming calls.
Go to Settings -> Call settings -> Call forwarding
Now Click on Always forward and enable it to forward the calls to a wrong number.
This will ensure that calls will not come to you and the caller get the tone that call is being forwarded and number is wrong.
You can disable Call forwarding ...
For me (CM 12.1), it is still confusing. You have to go under Settings, Data Usage and then:
make sure that both Data connection and Set mobile data limit toggles are ON
below them, there is range of dates dropdown, which you can choose to see data usage of previous months. Click on it, and you will get a list of previous periods.
now, you have to scroll ...
Samsung phones have an option to sync data in the background, disabling it, saves data, as updates are only checked for when an app is open (email/im/whatsapp etc). You need to enable that (see green icon in image below) to let your apps periodically check for data.

TLDR: use a SIM with a different number (no matter if Vodafone or a different service).
We see a symptom (no net), but we have to find out the cause first, to solve the problem. So let's think step by step, what the problem could be.
No, your other phone (the SII) doesn't work either (using the same SIM).*
No, you have already ...
Settings > Accounts & Sync > Uncheck "Background Data"
This will disable data use for all apps which are not your current foreground application, however a few apps might ignore it.
For further peace of mind, try the Onavo Count app, which keeps track of which apps are using your data, and can be set to force close certain apps of your choosing when ...
To borrow an answer from a previous question I answered, you could use a firewall. By specifying rules for what programs are allowed to access the Internet, even enabling the connection would still block them in the firewall, and they would not access the net. This way, you can block any app except the apps you want to always be allowed (if any), and then ...
A quite close profile is described at Tasker-Profile (Google-Translate English variant here). I will try to give an abstract here:
Basic Data On/Off
You will need two tasks for this:
enable mobile data:
Net -> Auto Sync (set ON)
Net -> Mobile Data (set ON)
disable mobile data:
Net -> Auto Sync (set ON)
Net -> Mobile Data (set ON)
You may ...
With on-board methods: You could go to Settings→Data Usage and setup and restrict "background data" for all apps. For this, you would first need to setup some (fake) limit of monthly data (5 TB is fine; you just need to set simething here). Then you can tap each app and activate the check-mark to "restrict background data".
Alternatively, you can pick some ...
Could this also be in your "Smart Manager". When you click on "Battery", it says "Optimising". When your apps are selected, it will only updates when you actually opens the app.
And it can also be your "power saving mode" problem in smart manager. Once you click on power saving it shows you restrict all background data, this should be disabled.
The answer is this varies by carrier and can vary for any number of other circumstances such as market, locale, and traffic density... Both answers you referenced are correct for certain situations. I have also seen DHCP leases in crowded mobile network areas be under 4 hours... So does your IP address change every time you connect? Sometimes it will, ...
They are all electromagnetic waves with different wavelengths. There had been no scientific evidence that they're dangerous in the power level used in common appliances, and many researches shows no evidence of danger in the short term studies, however many countries adopts the precautionary approach and advises people to minimize exposure just in case since ...
By default, as soon as WiFi gets connected, the mobile network shuts down -- so you cannot use both simultaneously. Which means: no, even a proxy allowing for exceptions would not do, as the other network simply is no longer available.
Quoting from CyanogenMod Tracker:
Each time you activate WiFi you'll lose 3g connection. That's normal behaviour of ...
It's impossible to add any custom shortcuts to Power button menu. Looks like you have installed some custom ROM. If that is the case, you could also try to find the ROM which has this feature embedded. Here's the list of custom ROMs for you phone:
XDA-Developers: all samsung galaxy mini custom roms!
The ROMs that are based on CyanogenMod (CM) have nice ...
You can periodically check status of real connection using HTTP GET by Tasker. You can restart the Data again by Tasker in case connection is stalled.
But, its down side is that it'll drain battery faster.
To manually start and stop internet: Go to Settings -> Wireless and networks -> Mobile networks and disable Mobile data. This will stop internet connection through mobile network. Enable this to start internet again.
To stop it permanently:
Some application may start internet automatically, So to prevent accidental internet consumption, Create a new ...
Click on the handle (a solid dot) on the right side of the red horizontal line above the orange line, and drag it down to 500MB. That adjusts the scale of the graph.
Look for the lime green arrow at right to see the handle.
I think I found it, as I had the same problem:
In the Settings go to Mobile Data.
Scroll down to item "Media" and tap it.
Scroll down and see if "Limit background data" is checked. If so, uncheck
This was the cause in my case, because for the Play Store app the same setting was not active. The problem with Android in this situation is, that there is a ...
I had the same issue. Found this solution on another site:
Open "Settings" App
Go to "SIM Card Manager"
Tap on "Data Service Network"
Choose the SIM as the Data SIM
Note that only the first SIM slot supports 3G Internet. So if you want to use 3G you must plug your 3G SIM in the first slot.
Android itself does not provide such a tool,
but you can use firewalls that require root,
If your device is not rooted, so no problem, there are some applications that use some trick that can prevent apps from being connected to internet, such as NoRoot Firewall.
The Trick of NoRoot Firewall is that it opens a Fake VPN connection
for making the phone ...
