A:AnswerHaha, coincidentally, I also have an iPhone6+, and also use it in a 2020 Toyota. I have had no issues using Apple CarPlay or just connecting via Bluetooth.
A:AnswerThe advantage is you’re not locked into any service provider. You can use Consumer Cellular, straight talk, cricket, whatever contract free carrier you want. You just add their sim to it and pay A LOT less for the same service coverage. We bought unlocked phones and changed over years ago and have never looked back.
