Riiing SIM dies in plastic wrap.

Back when Riiing first came out I purchased two and kept one in the plastic. I called UM about December and asked about the one that was still in the wrapper and was told that it was still good. I unwrapped it yesterday to register it for the SIM swap but it came up as "Unregistered SIM". So it looks like they do have a limited life in the wrapper.
