Your Fortress Against Internet Outages: Dual-SIM & WAN Failover
The Cudy LT700 is more than just a router – it's your personal guarantee for a stable internet connection. Thanks to the clever Dual-SIM Failover function, you can insert two SIM cards, even from different providers. If one connection fails, the device switches lightning-fast and automatically to the second card. But that's not all: You can also connect an existing wired connection (DSL, fiber optic) to the WAN port. If this also fails, the 4G Network immediately takes over. This triple security makes the LT700 the perfect choice for the home office, small businesses, and anyone for whom a connection interruption is not an option. A true professional among 4G / 5G Routers.
High-Speed 4G+ thanks to Cat. 6 and Carrier Aggregation
While many standard routers rely on slower Cat. 4 technology, the LT700 plays in a higher league. As a 4G Cat. 6 device, it supports Carrier Aggregation (2CA). This means it bundles the power of two mobile frequency bands simultaneously to speed up data transmission. The result is theoretical download speeds of up to 300 Mbit/s and a significantly more stable connection, especially in heavily utilized radio cells. Whether 4K streaming, online gaming, or downloading large files – the LT700 delivers the necessary power.
Full Control for Professionals: External Antennas and VPN Power
The Cudy LT700 is the perfect 4G Router for poor reception. Its four external mobile Antennas are detachable via standard SMA connectors. This gives you the freedom to connect powerful external directional or omnidirectional Antennas if needed, thus massively improving reception even in remote locations. But the flexibility doesn't end there: With features like Band Lock, you can set the router to the fastest frequency bands of your provider. Comprehensive VPN support with modern protocols like WireGuard and OpenVPN also enables secure remote access to your home Network or the connection of the entire Network to an external VPN Service.
Easy Start, Stay Strong: Plug-and-Play with Depth
Despite its professional functions, setting up the Cudy LT700 is incredibly simple. In most cases, it is enough to insert the Nano-SIM card and switch on the device – the router configures itself and establishes the connection. Via the clear web interface, which you simply access in your browser, you have access to all settings. Here you can set up guest networks, define WiFi schedules, or activate advanced functions such as DNS over TLS for more privacy. The LT700 proves that high performance and ease of use can go hand in hand.

Frequently Asked Questions (FAQ)
Can I use any SIM card with the Cudy LT700?
Yes, the router is unlocked for all providers. You need a Nano-SIM card with an active data plan. It is recommended to match the router's supported LTE frequency bands with your mobile provider's bands before purchase to ensure maximum compatibility and speed.
What does 'Dual-SIM-Failover' mean?
You can insert two SIM cards, even from different providers. The router uses one as the primary connection. If this fails or loses signal, the device automatically and seamlessly switches to the second SIM card to maintain the internet connection.
Is the setup complicated for technical novices?
No, the initial setup is usually very simple. After inserting the SIM card and powering on, the router usually connects automatically. For configuration, there is a user-friendly web interface accessible via cudy.net or 192.168.10.1.
Can I improve the router's mobile reception?
Yes, this is one of the strengths of the LT700. The four external cellular antennas are detachable via SMA connectors. In case of a weak signal, you can replace them with larger or directional outdoor antennas to significantly boost reception and thus the stability and speed of the internet connection.
Does the Cudy LT700 support VPN connections?
Yes, it offers exceptionally broad support for VPNs. You can use it as a client to connect the entire network to an external VPN Service. Additionally, it can function as its own VPN server (OpenVPN, WireGuard) to enable secure remote access to your home network.
What is the difference between LTE Cat. 4 and Cat. 6 in the LT700?
LTE Cat. 6, as used in the LT700, supports 'Carrier Aggregation'. This means the router can use two mobile frequency bands simultaneously to download data. In practice, this leads to a theoretically twice as high download speed (up to 300 Mbit/s) compared to Cat. 4 (up to 150 Mbit/s) and ensures a more stable connection.
