If you're on Sprint or Verizon, you won't be able to see the APN settings until you insert the card. (You'll want to disable data roaming in the Cellular menu before inserting the SIM if you're still at home to avoid immediately burning through the credit on your SIM with expensive international roaming.) If it's blank, set the APN to "orangeworld", and the username/password to "orange".
