Hi @Stephanie309 Guests enquiries are sent through the Airbnb messaging system, not directly from guest to host, and will come up on your father's mobile phone if his number is listed on the account. The guests don't have his actual mobile number, Airbnb does - they use a number of different phone numbers in their system to send the messages, none of which belong to guests. Hope that makes sense! Private information is hidden until the booking is confirmed - that's why you can't respond directly from your cellphone to a text message sent from a guest - the number shown is not the guest's actual number. Hope that helps! Karen
