How can I be able to be update my iPhone 6s to iPhone 7 Plus

You can't update your iPhone to another model, you need to buy a newer model.

You marked your question as solved, not sure if it is solved, a response before you get disappointed in the future.

You can't update iPhone 6S to iOS 16, but you can't update iPhone 7 Plus to iOS 16 either.

So it makes no sense to buy iPhone 7 Plus.

See -> iOS 16 -> iOS 16 - Apple

If you want to buy a 'newer' iPhone, read this first:
