most mobile carriers in the US (last i checked anyway) go through asurion. 60 dollar deductable and they send you a new (see: refurb) device. if you say it was stolen, they want a police report. if you lost it, all good.
i havent paid for insurance on a phone in the greater part of a decade and ive only ever used it ONCE, back in the day when i had cingular. not worth another monthly charge IMO
