Here's what you'll find in the box:
Your iPhone 6s Plus uses a NanoSIM, which goes onto a SIM tray in the side of the phone.
Push the SIM removal tool into the pinhole on the right-hand edge of the phone, until the tray starts to pop out.
Pull the tray out the rest of the way.
Put the NanoSIM onto the tray, with the metal contacts facing down, and the cut-off corner facing outwards.
Push the tray back into the phone.
With the SIM in, press and hold the power button on the right-hand edge for 2-3 seconds until the Apple logo appears, and you can start setting up the phone.
When you turn your phone on for the first time, it'll show the 'Setup Wizard', which is a series of steps that'll help you get your phone ready to use.
Swipe across the screen to get started.

The next step asks you how you want to set up the rest of the phone. This guide is for people who have used an iPhone before, and want to transfer their data from their old one.

The Setup Wizard is finished, and you'll be looking at the Home screen.
Your iPhone has some buttons that help you get around the phone.
'Home button': this will do different things, depending on how it's pressed.
