Hi @Zakria,
I've taken a look in one of the Xperia C4's we have here and I receive this notification every time I disable mobile data, the notification is removed when enabling mobile data again.
However as far as I know you should be able to remove this notification by swiping it left or right. Note that the notification will reappear if you enable and disable mobile data again, to my knowledge there isn't any way to disable this.
I'll be happy to forward any feedback you may have
