C.Ann, you don't need a card w/ OneSuite or Bigzoo. They send you an email right away when you sign up w/ your access code in it. You can start using it right then!
I use it for all my LD, even at home. I program in thier phone number in one Memory button and my access number in another. When I need to make a call, it's easy as pie! I hit Mem1 to call them; when it asks for my access code, I hit Mem2.
