  Read RFC 4186.  Those fields are required for EAP-SIM to work.

  Some device manufacturers don't bother reading the specifications.
You should ask for your money back.  Or, throw the devices in the garbage.

  If they don't bother to test their device against existing
implementations, they might as well be writing code and shipping it as
soon as it compiles.  They're incompetent, and uncaring.
