Hi @Cristal43 !
Do you happen to another Profile on Airbnb also using that phone number? Perhaps an old one you have forgotten about?
Airbnb will not allow you to use your new phone number on the profile you are trying to update, if its used on another profile. If you have two or more profiles, you will need to use email, or one of the other login methods to access your account.

Hope this helps!
