If your phone will run the Tesla app, then that might be OK for you. The app is useful for unlocking/locking, checking charge progress whilst you're not in the car, pre-heating/cooling, but it isn't essential. Depends what you're happy with. As has been said, I always carry one of the cards with me anyway in case I break or lose my phone whilst away from the car.
I'm no expert, but not all phones can benefit from the wireless charging. This is a real plus as far as I'm concerned as there are no untidy cables and you know your phone is fully charged after a long journey. I know that my Samsung 'S' is OK with that, but my wife's 'A' isn't.
I also use my phone for audiobooks and music whilst in the car - but still have a lots of music on an SD card plugged in via a USB adaptor. I'm a heavy mobile call user mainly due to my work, so having something that is as seamless as possible is a plus for me.
If you're OK with not accessing the app, as it isn't necessary to drive the car, then even if it won't work on your phone it isn't the end of the world.
