The Cudy AC1200 Unlocked 4G LTE Modem Router is a versatile device designed for users who need reliable internet in areas without traditional broadband. It supports major 4G providers in North America, offering download speeds up to 150Mbps. Simply insert a SIM card from AT&T or T-Mobile, and you're ready to connect all your Wi-Fi devices.

One of the standout features is its dual-band Wi-Fi capability, providing both 2.4GHz and 5GHz bands. This allows for seamless multitasking: the 2.4GHz band handles basic tasks like web browsing, while the 5GHz band manages bandwidth-intensive activities such as online gaming and streaming.

The router also boasts detachable cellular antennas, enhancing signal quality and offering flexibility for outdoor installations. Additionally, it supports multiple VPN protocols (PPTP/L2TP/OpenVPN/WireGuard/IPsec), ensuring secure data transmission.

However, some users have reported challenges during setup, particularly with specific carrier settings. For instance, adjustments to TTL, HL, and APN settings were necessary for optimal performance with certain providers like Visible. Despite these initial hurdles, many users found the router's performance impressive once configured correctly.

In summary, the Cudy AC1200 is a robust solution for those needing reliable internet in remote locations or as a backup connection. While setup may require some technical know-how, its performance and features make it a worthwhile investment.
