I'll give a different Point of view. For me, I never get the insurance. Why? I have never lost or damaged my phone ever. I still have my old Motorola Phone (my first color phone lol, when they first started coming out with colored displays that weren't so expensive) from 10 years ago. I'm really anal about my devices and try to make sure I never put it in a situation that will leave me losing or breaking it.
So I think you should look back at your history, have you ever broken your phone? Have you ever lost your phone/had it stolen? If not, maybe you might not need insurance. But if the likely hood is high, then sure the insurance will definitely be a huge benefit for you!
