Excuse me, how can Sunshine Insurance call to insure, ask for the birthday and name, and then send a text message saying that the policy is valid? How to cancel? Please hurry back.

First of all, this is definitely just a gift accident insurance, because you only asked your birthday and name, so you don't have to pay, and this kind of accident insurance has a short guarantee period, maybe only one or two months, so there is no need to cancel it. What you are worried about may be that Sunshine Insurance will call and harass you in the future!
