Mr.Sao (staff of emergency of Hong Kong): Your Sim card ring 100 times each minute. Because, there're over 100 people calling 999 each minute. 

Kelvin: No worry. If John call 999, it bind 999 to my physical address. . Else, it bind 999 to the emergency's department. Now, John call 999 to request an ambulance to pick up Mr. N. You're gonna ridicule Mr.N.

Mr.Sao: Fine. But, you must hack the database of the public hospital of Hong Kong and then you provide me with the full details of Mr.N .
