This document explains how to use the virtual number selection feature during the WhatsApp Business API (WABA) setup process.
The virtual number feature provides the following advantages:
Does not require a physical SIM card.
Accelerates the WABA setup process.
Offers a low entry barrier for users who want to try the platform.
During the WABA setup process, all users encounter the following screen.
When the "Click to Purchase Number" button is pressed, the number addition field opens.
The following fields are located within the relevant area:
Phone Number: An automatic number is displayed to the user.
Refresh button: When clicked, a random new number is displayed to the user.
"I Will Choose My Own Number" button: Allows the user to select their own number.
Currently, only US-compatible phone numbers can be obtained.
When the "Select Number" button is clicked, the user is directed to a summary screen.
The selected number is displayed here.
The selected number is reserved for the user for 15 minutes. If the user waits more than 15 minutes on this screen, the number reservation will be cancelled.
After clicking the "Complete" button:
An OTP (verification code) is received from Meta via SMS in the background.
The code is automatically verified.
The user proceeds to the "Setup Completing" screen, which is the final step of the setup.
