Does Debon Express know that the recipient's mobile phone number can be checked?

Yes, there is "mobile phone number inquiry" on the top right of the cargo tracking search column on the homepage of Debon Express official website. Click in, enter the mobile phone number, and then you need to send a verification message to the mobile phone number, enter the verification code received by your mobile phone message, and then inquire. This is the computer I just went to Debon official website to test.
