Check coverage page shows the phone is already activated, but I haven't received the new phone yet
I want to purchase an iPhone 13 that's supposedly still sealed from a private person. If I check its serial number on the Check Your Service and Support Coverage - Apple Support page, it says
Telephone Technical Support: Active, Estimated Expiration Date: June 24, 2022
Repairs and Service Coverage: Active, Estimated Expiration Date: March 25, 2023
Can an iPhone be activated while being in a sealed box? Or does this mean this iPhone has been used before and this seller is not to be trusted?
