Party Pay is great! It's not related to wifi in any way. It allows you to get a full group discount each month (so instead of paying $40 unlimited each month you can join a group so that service is just $25/month unlimited everything). I didn't have 3 other people to join, so I joined a group I found on the visible forums. With party pay, Visible's app will tell you how many people are in the group you join, but it keeps everyone's identity anonymous (like in our group I can see we have over 2,600 people in it right now but I don't know who any of them are.) Visible bills everyone completely separately in a group too so you won't ever be on the hook for someone's unpaid bill, and they have no limit on group size. You're welcome to join our group if you are interested. If you aren't a Visible customer, you can get your first month of service for just $5. After you sign up and activate your service, you can join our group. We'd be happy to have you in our group.
