Used — Professionally Refurbished by STS Technologies LLC

This listing is for a Moxee K779HSDL 4G LTE hotspot professionally refurbished and pre-installed with the latest stable version of RayHunter — the open-source cellular surveillance detection tool used to identify IMSI catchers, Stingrays, forced downgrades, and abnormal tower behavior.

Each unit comes from bulk enterprise liquidation and may show light cosmetic wear from prior use. Every device goes through our full refurbishment and verification process:

• Hardware inspection

• Battery and charging test

• Wi-Fi and USB tethering validation

• Modem / IMEI health check

• Web interface reset

• Fresh RayHunter installation and functional test

Only devices that pass 100% of our checks are shipped.

🛰️ What RayHunter Detects

RayHunter continuously monitors LTE control-plane signaling and alerts you to:

• IMSI catchers

• Cell-site simulators (“Stingrays”)

• Forced 2G/3G downgrades

• Rogue or abnormal tower behavior

• Suspicious mobility events

• Potential interception activity

Note: This means that there is no guarantee on receiving a sim card.
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.
