I want to have ios 13, but my cell phone is iPhone 6 Plus

I too have the iPhone 6+ and can't update to iOS 13 because my iPhone is too old. I still have updates coming to my iPhone 6+ and I only use my iPhone 6+ when I leave my home because I purchased a new Apple desktop with a Thunderbolt screen as a older senior. It cost me a lot because my last Apple computer was a Apple IIVX that I purchased when Apple sold it and it weight was so heavy that I had to use a hand truck to moved it around my home.

You can’t have iOS 13 on an iPhone 6 Plus. It lacks the hardware that iOS 13 requires.
