Add another line (a second parent or grandparent)

The Family plan covers up to 3 protected lines — both parents, or a parent plus a grandparent.

1. In the app, tap Add a line and enter the new phone number.
2. We detect the carrier and show the forwarding code to dial, then place a test call — the same quick setup as your first line.

On the One Line plan and need more? Switch to Family anytime from Account → Manage billing. The change is prorated and takes effect right away.
