From insurance provider Asurion’s contract.
L. Any Loss or damage caused by or through or in consequence, directly or indirectly, of Nuclear Hazard, meaning any weapon employing atomic fission or fusion; or nuclear reaction or radiation or radioactive contamination from any other cause; but we will pay for direct physical Loss caused by resulting fire, if the fire would be covered under this Certificate.
So, after WWIII be sure to claim your phone was lost in the resulting global firestorm, and not from the explosions themselves.
And yes I’m well aware that this is mainly to account for phone loss due to terrorist activity and not nuclear warfare, but it’s still kind of funny.
