This Kajeet RC400L(X) 4G LTE mobile hotspot comes professionally refurbished and pre-installed with RayHunter, the open-source cellular surveillance detection tool trusted by researchers, privacy advocates, and security professionals. RayHunter continuously monitors LTE signaling to identify IMSI catchers, Stingrays, forced network downgrades, and abnormal tower behavior.

Each unit is sourced from enterprise liquidation and restored by STS Technologies LLC through a full refurbishment process including hardware inspection, battery testing, charging validation, modem health checks, Wi-Fi verification, and a fresh RayHunter installation.

Get one from your carrier ideally. Otherwise Walmart and Amazon have basically any sim card you could need for $5 or less. Refunds will not be accepted on the basis of a sim card being missing, not working, etc.

Note: Due to the nature of how we procure these devices from multiple vendors and resellers, we can not make any guarantee based on the availability of sim cards or the quality / life of the battery. You're buying a complete Rayhunter device with the items as listed. If something is missing that you think you need, be sure to get that separately.

Note: If you want a more premium device, look our New In Box Rayhunter or our Open Box Ray Hunter listings.
