Why did Tradejini send an email stating certain mobile numbers are blocked?

Tradejini sent you an email about a blocked mobile number because the regulatory authority, TRAI (Telecom Regulatory Authority of India), provides a list of permanently disconnected mobile numbers called the Mobile Number Revocation List (MNRL). This list is available on their secure website https://mnrl.trai.gov.in and is updated monthly. Since TRAI has mentioned that certain numbers are not vaild, therefore we at Tradejini diligently inform our clients through an email requesting them to update their registered mobile number.
