As a Customer of reliance communication recently I had ported to Idea. But there is an advertisement before every call, I can understand that there is something I cant say as they earn from this way. but even after porting my number I started receiving spam calls which was not registered with any one. Daily I receive almost 15 spam calls. Even 1 call I had received that was of very critical call asking for OTP of Aadhar.(Please dont share the same with anyone). I will request IDEA not to share any details of us to un-authorized partners.
