Yes. We have the family plan.
It works well for us. We currently have 3 phones and a tablet on our plan.
Dh's work gives us a 25% discount and pays his portion (about $50) so we pay $25 for the plan plus $15 per phone and $10 per tablet, equalling $65 plus about $10 in tax OOP.
Dh's phone was purchased through work and they paid for it. I found an iPhone 5 on CL and my son has a Galaxy 3 from CL.
