How to turn off mobile data on a Samsung Galaxy S4

In today's world we all seem to use mobile data every single day. Whether we are just browsing the net, checking twitter, uploading pictures to facebook, streaming live video of Japanese TV (yes, yes, I know that's just me!) or using an instant messenger like Skype or Whatsapp.

Now a days however we get plenty of chances to log on to a Wi-fi network, be it our own in our own houses, one we have access to through our service provider or a general one in a restaurant, cafe or hotel. When you can get a Wi-Fi signal it's usually a better (read "faster" and "more stable") connection than you'd get using mobile data so it's advised to turn off your mobile data to save battery power whilst connected to Wi-fi.

With the Samsung Galaxy S2 (and various other Androids) there is actually 2 ways in which a user can turn off their mobile internet:

Method 1-If you drag down the notification bar and scroll across slightly you will get the option of "Mobile data" if you press on this and turn the light off this will turn off mobile data and save the battery. (For reference see above).

Method 2-Alternatively if you hold the power button you will get a "Device options" screen (see the picture to the right) which allows you to turn off "Date network mode" which is actually the same thing.

To turn it back on you can just do every thing again but make sure the light is "on" in the notification panel or the option says "activated".

For most of he time the notification bar method is the easiest and quickest, but for the few occasions where it may be difficult to access the bar, the  "Device options" method may be an easier alternative.

3G Watchdog

 After having used 3G Watchdog since getting my HTC Wildfire (and subsequently my Samsung Galaxy S2) it seems only fair to look at one of the must have apps for any mobile internet using android phone users. The basic app is available for free from the Market and is one that you should already have (and if you don't, get it now!).

What is 3G Watchdog?
The application is currently the best way to keep track of your data usage on an Android phone. It does this by recording all your usage in a screen like the one in the image to the right hand side.

 For those who are on a capped allowance of mobile data, this is an application that will allow you to set a your plan into the app and then track how much data you are using. The screenshot to the left is the plan setting, which allows you to select your allowance, you time span, you reset date and when you want the phone to alert you that you're getting close to your limit (i.e. when 75% of your allowance is used).

As well as tracking usage through the month the app also allows you to see data usage for the last 31 days as both received and sent this is where the application can do that little bit extra.

If you're on a capped allowance, no matter how big, 3G Watchdog is a must have app that will allow you to track the usage on your phone. It adds a feature that SHOULD have been put in the phones when they were made.
