Step 1 : Goto Menu > Settings > Configuration Settings
Step 2 : In Preferred access point, we have various set of settings among which one is the actual working Internet Setting.
Example, In this particular device we have “Aircel Network” so we have the following settings,
So the first one i.e., Aircel Pocket Internet is the working one.
Step 3 : Now to turn of Internet all you have to do is select another setting lets say Aircel MMS in the above case.
Once you select MMS setting you Mobile Data will be turned off.
Step 4 : To turn it back on, all you have to do is select the actual working setting back again.
Isn’t that a simple alternative to achieve the Mobile Data ON and OFF feature.
