First, make sure you have an iPhone 6S plus. Go to Settings > General > About and look at the model number.
• If you have an iPhone 5S or 6/6plus, the highest you can update to is 12.5.7
• If you have an iPhone 6S through 7, or SE 1st generation, you can update to 15.7.6
What happens when you try?
Can you post a screenshot of the whole screen, it could reveal why you aren't able to update.
Make sure you:
• Are using a WiFi connection (not a hotspot).
• You have an active cell signal (You need both WiFi and cellular service to perform the upgrade).
• Are not using a VPN connection.
• Have your battery charged at least 50%. Better yet, keep it plugged in during the update.
• Do not have power save mode turned on.
• Do not have a beta version installed.
• You have at least 10 gigs of storage available.
