We took out college student insurance when our kids were in college, both in the dorm and in off campus housing. Believe we used the predecessor to Gallagher and Gallagher.
It was inexpensive, and did cover a cell phone when son’s got messed up accidentally.
Our insurance didn’t give us much of a discount on the kid that was 350 miles away, and 0 discount on kid less than 50 miles away. We kept them insured, and we paid a fortune for car insurance. Probably stupid, but I could sleep well at night knowing they were well insured.
We also took out an umbrella policy about the time we had 2 teenaged male drivers… so I guess we are risk averse.
