The blackberry passport has sexy looks and unique designs but.
lets look on this one by one: -
1.The blackberry OS hs stopped development and the latest OS you get in blackberry is BB10
Most of the android applications doesnt support
No VOLTE support, because of that jio foesnt work over it.
You can root it neither you could use like a android phone.
5.Blackberry apps stopped development , hence whatsapp is not even available for bb passport.
Even if the phone is unique , it doesnt have the basic nessecities to run in the modern era of smart phone , its better not to buy it.
The battery capactiy is brilliant.
