How do I add phone number? I don't use WhatsApp.

“In certain countries you can complete phone verification with WhatsApp instead of via an SMS.”

You’re absolutely right, read that one too quickly, sorry for that!

And I’ve tried to find any other info about why the SMS doesn’t appear as an option and couldn’t find anything related to that. I have WhatsApp, so I’ve actually never thought about SMS as an option.

The best way, if there’s no one else that actually knows about why the SMS option doesn’t show as an option, is to contact Help center https://help.openai.com/en and ask them.

Again I’m sorry for the misleading information.
