You should try to have a Chat session with Verizon. It should be pretty quick and often you'll find each Verizon rep has different information. I'm guessing you want it installed at a friend/family home?
You could have your partner sign up for one on a different account. There is only one account holder per account.
Call back and try again. That doesn't sound like anything I have heard about VZWs LTE Internet Installed program.
