The Cudy AC1200 Unlocked 4G LTE Modem Router is a versatile device designed for users who need reliable internet in areas without traditional cable connections. With support for major 4G providers in North America, this router converts 4G LTE signals into WiFi, offering speeds up to 150Mbps. Its dual-band WiFi (2.4GHz and 5GHz) ensures smooth performance for both light browsing and bandwidth-intensive tasks like streaming or gaming.

One standout feature is the detachable cellular antennas, which allow for flexible installation and improved signal quality. Users have reported success with various SIM cards, including those from Visible and Consumer Cellular, though some noted the need to adjust settings like TTL, HL, and APN for optimal performance.

The router also supports multiple VPN protocols (PPTP/L2TP/OpenVPN/WireGuard/IPsec) and DNS encryption, enhancing security. However, some users found the setup process challenging due to unclear instructions and issues with the Cudy app or website configuration.

While many praised its performance and reliability, others experienced frequent signal drops or difficulties with failover to a secondary SIM card. Despite these drawbacks, the Cudy AC1200 remains a solid choice for remote locations or as a backup internet solution.
