This no-contract modem is perfect for existing Sprint customers who want to swap to a more current device or need to replace a lost/broken device, but don't want to alter their contract (purchasing this device will NOT extend or alter your Sprint contract - once you get the new device, simply swap your LTE SIM card from your old device to the new one; if you're swapping from a 3G or WiMAX device [which don't use SIMs] you will need to obtain a SIM from Sprint). This device is refurbished; it is in like-new condition but does not include the original packaging/accessories.

IMPORTANT: This is a 4G LTE-capable modem and requires a 4G SIM from Sprint.

IMPORTANT: This is a Sprint modem - it cannot be used for any other service providers.

You may need Sprint SmartView to activate your modem - if you don't already have it installed, you can download it from Sprint's website
