SIM Cards

How do I know what kind or size SIM card I need?

For service on Flash Wireless, you must use a Flash Wireless SIM card. If you do not have a Flash Wireless SIM card and you would like to bring your own device, you will be provided the option to receive one for free when you validate your device with the Device Approval Wizard. The Flash Wireless SIM cards are triple punched. One card has all three sizes; simply select a size and detach from the card. For a listing of SIM card sizes, please see the SIM card Size Guide.
