Hu @naveen_prasad86 , I'm going to go out on a limb and call it a scam. I googled the number and it looks like it's been reported by customers of other carriers also as a scam.
Hello Naveen_prasad86,
Unfortunately, I would highly suspect those calls to be SCAMS. Neither of those numbers appear to be from Fido and giving away the top-end devices for free would seem to be too good to be true.
You can view Fido's current promotions here.

They can also be contacted via Live Chat, Facebook, or Twitter. Those methods can be accessed via the contact page posted above.
Hope this helps 😀
Cheers
