Q: When I click "view account" I get an error message that says "SIM is invalid; please use different SIM." What next?

I am trying to activate a first gen iPad with WiFi and 3G. When I go to Settings, Cellular Data, and View Account to activate the iPad, I get an error message that says, "SIM is Invalid.  Pleae use a different SIM." 

 

There is a SIM PIN option, and when I click that it asks for the PIN.  I don't have a PW for the SIM (the iPad was a slightly used gift, and none of the paperwork came with the iPad). 

 

Any ideas on how to activate the iPAD?

 

Thanks!
