LM150 Dual SIM 4G-LTE Router: The Ultimate POTS Replacement Solution


The LM150 is a high-performance 4G VoLTE gateway engineered specifically to bridge the gap between legacy analog systems and modern cellular networks. As traditional copper lines (POTS) become obsolete and increasingly expensive, the LM150 provides a seamless, enterprise-grade transition for voice and data.


Key Features and Benefits

  • Reliable POTS Replacement: Equipped with an integrated FXS port, the LM150 allows you to connect existing analog phones and fax machines directly to a cellular network via VoLTE, maintaining crystal-clear voice quality without the high cost of landlines.
  • Dual-SIM Redundancy: Featuring two plug-and-play SIM slots, the LM150 ensures maximum uptime. The dual-SIM architecture allows for carrier failover, ensuring your critical communication and networking stay online even if one provider’s signal wavers.
  • High-Speed Connectivity: Powered by a CAT-4 LTE module, this router delivers the bandwidth necessary for reliable IP communication, remote monitoring, and small office networking.
  • Precision & Customization: The device includes three SMA interfaces for external antennas (Main, Aux, and GNSS). This allows users to optimize signal reception in weak-coverage areas and leverage precise satellite positioning for mobile or remote assets.
  • Simplified Deployment (PoE): The integrated LAN port supports Power over Ethernet (PoE-in), allowing you to install the device in optimal signal locations (like high on a wall or in an attic) without needing a nearby power outlet.


Seamless Integration

For a comprehensive communication overhaul, the LM150 is designed to pair perfectly with the PR08 gateway. Together, they form a robust "4G LTE + POTS Replacement" ecosystem, providing a reliable, future-proof IP communication solution for businesses of any size.


Why Choose the LM150?

In an era where connectivity is non-negotiable, the LM150 offers the flexibility of a mobile router with the stability of a traditional landline. Whether you are upgrading an emergency elevator phone, a remote office, or a retail POS system, the LM150 delivers the performance and peace of mind you need.

Dual-SIM Card With Network Auto-Switch

The LM150 features an integrated Cat 4 LTE module and supports plug-and-play functionality, enabling rapid deployment across various networking environments.


Equipped with a Dual-SIM auto-switch feature, the device provides robust redundancy for mission-critical communication. If the primary SIM experiences a connectivity failure or abnormality, the system automatically transitions to the secondary SIM. This immediate failover switches the network link and call account, ensuring stable, reliable, and uninterrupted IP communication.
