I Just purchase a New Blackberry Passport but stating that It don't support Whatsapp, Please don't force me to purchase another phone.
Hi Yvonne. Welcome to The Informr forums.
To your question...unfortunately only a few devices from BlackBerry are supported. The Priv and the DTEK50 for example. Both of those run Android, not BlackBerry's own operating systems.
After June 30th 2017 WhatsApp announced that their Messenger will no longer support any BlackBerries running a BlackBerry OS.
