This refurbished no-contract USB modem is "like new" and is perfect for existing T-Mobile 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 T-Mobile contract - once you get the new device, simply swap the SIM card from your old device to the new one). This device can also be used for T-Mobile's pre-paid service (you will need to contact T-Mobile after receiving the modem to sign up for service and acquire a SIM card). *this modem has a standard-sized SIM slot - if you plan to use a microSIM, you'll need the micro-to-standard SIM adapter
