Apple watch Cellular for use with Android

I would like to purchase a apple watch for both my wife and myself both will be cellular versions. I use a iphone but my wife uses an android device. I have found that i can setup her watch via my Setup for a family member option on the watch app.Will her apple watch device still receive notifications when she activates a cellular plan? Will she be able to make calls and receive her notifications via the android phone or not? Thanks any help would be appreciated.
