I know this bus an old topic, but I just spent 5 hours talking to six different people between tech, customer service and sales.   All told me something different.   The good news is the sum fired up and connected perfectly.  And worked for a while.   The bad news was our senior plan would not allow us to add the SIM card.   So we lose the senior plan or lose the sim.   We lost the sim.   mess Verizon and their stupid rules.  I sent a letter to Romney Dunne.   We’ll see.  We were told by several people that we could add the sim for 10$ a month and not lose our plans, but the supervisor said not true.... we were told they could grandfather the SIM card into our plans, also not true.   Lots of lies and misinformation....very sad .   We love Verizon but not this!!!
