D-Link Wireless N300 4G Dual SIM LTE Router (DWR-M930DS)
The D-Link DWR-M930DS Wireless N300 4G Dual SIM LTE Router is a practical upgrade over standard 4G routers, mainly because it supports dual SIM with automatic failover. It’s designed for users who need stable connectivity, especially for small offices, retail shops, or environments relying on mobile internet as a primary or backup connection.
Dual SIM Failover = Always Connected
The key feature is dual nano SIM slots, where one SIM is active and the second acts as backup. If your main telco drops or becomes unstable, the router automatically switches to the second SIM. This ensures minimal downtime, which is critical for business operations.
4G LTE + N300 WiFi Performance
It delivers 4G LTE speeds up to 150 Mbps download and 50 Mbps upload, paired with 300 Mbps WiFi on 2.4GHz. This is sufficient for daily usage like video calls, browsing, POS systems, and light streaming, though not meant for heavy bandwidth workloads.
Wired + Wireless Flexibility
Unlike portable hotspots, this is a fixed router with multiple LAN ports and a WAN port, allowing you to connect desktops, switches, or even another internet line. It also supports WAN failover between wired broadband and 4G for added redundancy.
Built for SME and Backup Use
This router includes essential networking features such as DHCP server, QoS for bandwidth control, DDNS, and firewall security, making it suitable for small business environments requiring consistent connectivity.
Easy Setup, Plug-and-Play
Setup is simple with plug-and-play functionality. Insert the SIM card, power on the device, and configure it through a web interface. Most telcos are supported with automatic APN detection, allowing quick deployment without technical expertise.
