Just look in your contacts list in the joyn app. Contacts who have joyn will have a yellow joyn logo to the right of their name.
If your friend is not using joyn, you can still call and text with them just as you do today. You can also send an invitation to download the application. Keep in mind your contact will also need to have a joyn compatible phone.
To see availability and status updates for your joyn contacts, you must request it from them. Open your friend’s contact card and turn “Profile sharing” on. Select “Save” and your friend will receive an invitation to share their social profile information with you. Once they have accepted your invitation, you will see their availability and status updates.
You can have up to 10 VIPs at a time.
The VIP feature allows you to select your closest friends and family to view their availability and status updates in real time. You must request VIP status from your contacts. Just open their contact card, turn “Profile sharing” on and then select VIP. Now select “Save” and your friend will receive an invitation to share their social profile information with you. Once they have accepted your invitation, you will see their availability and status updates in real time.
To set up a group just open the joyn app and select the plus sign in the Contacts tab. Select “add group”. Enter a group name and tap all of the contacts you want in the group. Now press “Save.”
