How you can get message detail of another persons mobile number?

Answer 1

That depends... If the mobile phone in question is listed on the contract of which you are the owner of the account, you can legally request information about any phone on the contract. (The owner of the contract is considered by law to own any phone/phone number listed on his contract, even if the person using that phone is over 18 years of age and pays the phone bill for that phone/phone number.

A judge can also order the relevant information be presented in his court when the owner of the phone/phone number is on trial/suspected to be involved with a criminal activity in which the phone records may hold evidence which could incriminate the owner of the phone/phone number.
