  • 1900 MHz (2G or 3G / 4G depending on location)

You can check whether your phone is compatible here.

  1. Click Check Compatibility
  2. Enter the US ZIP code of where you're travelling to (you can Google "New York ZIP code") and click Verify
  3. Choose your phone brand and model

How do I know if my device is unlocked?
