How do I convince my parents to get me the iPhone 11 Pro Max for my birthday?

It's the only thing I really want. I still have the iPhone 6.

Threaten to hold your breath and stomp your feet.

Maybe you can bribe them into it

Give enough money to pay for one and I think they would definitely gwt you one!

Start whining in front of them and maybe they will reconsider their choices.

Ask for one? I buy all my phones
