Is my phone supported?

I got a new phone and the phone number stayed the same but its a different model. I got it for my birthday days ago. I’m unsure how many phones are supported by Blizzard Authenticator. I know they say I phones and IOS. My question is the model of phone supported in case certain models that may be on the list but doesn’t support it?

Here’s my phone I may get it wrong and I’m looking at the manual on the back listing what it is. My phone is a Atat cingular flip 4. KaiOS 4G LTE. From there on it give no more specs.
