What if I change my Locatee’s cell phone or Calling Plan after setting up Family Locator?
Family Locator will not preserve your settings for a Calling Plan Change. If you change any Locatee cell phone, you will have to download the Family Locator Member application to the new phones. To continue to receive location & arrival updates as you did prior to your phone change, you will have to set up Arrival & Departure updates, Locations and Contacts again to continue to receive them.
