I've been a bit confused about how EIP payments should work. I'm on a family plan so I'm not the primary account holder. Is my EIP payment included in our monthly bill or not? For example, my payment is $21 per month. If the primary account holder pays the whole bill in full, he's paying my $21 as well? In other words, does/should my EIP balance go down, or does that portion HAVE to be paid separately for it to reflect properly?
I've done this both ways: 1) I've called to make solely an EIP payment (because for some reason I'm STILL not able to make one online, even though a ticket has supposedly been opened, but that's another story), and 2) I've just waited for the primary account holder to pay the whole bill and then given him $21. Is the second option okay, that I just give him the money to make this easier?
