Hi all I have been scouring the news articles for more info on the Fall Detection on the AW4 but can't find answers to: - Appears you need the AW4 Cellular version for the Fall Detection feature, correct? - If I buy the GPS, non-Cellular version and fall, would the AW4 still make an emergency call if paired/near iPhone? - For the emergency contacts, is it possible to also send a Whatsapp message to specified contacts? - Does Whatsapp notifications/etc work on the AW4 Cellular version without an iPhone tethered? Thanks in advance!
