You’ll need to use a supported phone number. Unsupported phone numbers can’t be registered on WhatsApp and include:
VoIP
Landlines
Note: Landlines are only supported on the WhatsApp Business app.
Toll-free numbers
Paid premium numbers
Universal access numbers (UAN)As RC phone number is a VOIP number, Whatsapp doesn't allow to receive verification SMS on RC number. We are looking to check for any other alternatives, but as of now there's no solution as it's blocked from Whatsapp.
