It was possible before lollipop using reflection. It is not possible any more.

What to do now? please help me because need to turn on data in android **5.0**. – Jakvar Jul 13 '15 at 16:02
There is nothing you can do my friend. They only allow this in system apps now. – Simar Jul 13 '15 at 16:03
how ,if device was rooted? – Jakvar Jul 16 '15 at 10:50
If your device is rooted you can run a linux script. System apps are those that come pre installed on a device. The ones that can't be uninstalled. – Simar Jul 16 '15 at 10:52
