Book a locker, send a package to another V-Box, or receive a delivery. Use the app on the phone, read your code in Messages, then go to the 3D locker, type the code on its keypad, put your item in or take it out, and close the door.
This is a demonstration. It does not connect to real lockers, payments or SMS. Prices, phone numbers and codes are made up. The real app is at app.vboxafrica.com.
