Hey, chriskeller.
I see that you're trying to set up Family Sharing and would like to know if the request can be sent through a text message. I'm happy to help.
Set up Family Sharing -- With iOS 11 and later, you can select "Invite via iMessage" to send Message or select "Invite in Person" where an email is sent.
As long as you're both using iOS 8 and later or OS X Yosemite and later, you can add anyone who has an Apple ID to your family. If you have children, use these steps to create their Apple ID and add them to your group. Use the steps below to add someone who already has an Apple ID.
On your iPhone, iPad, or iPod touch:
- Go to Settings > [your name] > Family Sharing. If you're using iOS 10.2 or earlier, go to Settings > iCloud > Family.
- Tap Add Family Member.
- Enter your family member's name or email address and follow the onscreen instructions.
- If you’re using iOS 11 or later, choose whether you’d like to send an invitation via Messages or to invite them in person. Then follow the onscreen instructions.
Accept or decline an invitation to join a family directly from your device. You'll get an invitation sent to you by email or in a text message. Then you can respond right from the invitation. If you miss the email or text invitation, no problem. You can respond from your device Settings or System Preferences:
- On your iPhone, iPad, or iPod touch, go to Settings > [your name] > Invitations. If you're using iOS 10.2 or earlier, go to Settings > iCloud > Invitations.
- On your Mac, choose Apple menu > System Preferences > iCloud > Manage Family.
To accept an invitation, follow the onscreen instructions. When you join a family, you might be asked to confirm your account information and to opt-in to any features or services your family set up.
Take care!
