Very often, it so happens that several features of your smartphone stop functioning like Google search engine stops working, you aren't able to make outgoing calls when you leave area of network service provider. This is really annoying.
Solution to this problem: Go to Settings -> Connections -> Mobile networks -> enable 'Data roaming' by moving the toggle towards right. Your smartphone shall again become smart enough to provide you all services again🙂🧚♂️🙋♀️!
