An interesting text message came from 9015105172 (Reliance Mobile Delhi NCR) today (17th May 2016) at 10:00 AM introducing herself as Samantha and the message was evident as a global scammer offering a lucrative sum of 3.9 million USD in India.

This makes one step clear that Reliance does not properly verify CAF details before activating mobile numbers.
We had another experience discussed here.
