InHand ER605 Ensures Uninterrupted Retail Connectivity with Dual SIM Carrier Failover

1. Scenario Background

A chain of retail outlets relies on stable cellular connectivity for POS transactions and video surveillance. Previously, single-SIM routers caused frequent network outages during poor carrier signal, leading to lost sales and gaps in security footage.

2. Product Selection

InHand ER605 Industrial Router — features Dual SIM redundancy, real-time link monitoring, and automatic carrier failover, ensuring uninterrupted connectivity for in-store business systems.

3. Core Solutions

Deploy ER605 at each outlet, connecting POS terminals, security cameras, and business systems via LAN/Wi-Fi.
ER605 uses Dual SIM cards to link to two separate cellular carriers.
Real-time link monitoring checks signal quality; if the primary carrier’s signal weakens or fails, the router automatically switches to the secondary carrier with stronger signal.

4. Implementation Results

99.99% network uptime (eliminated POS transaction failures due to outages).
No gaps in video surveillance footage (critical for loss prevention).
70% reduction in on-site IT support (fewer network-related issues to resolve).
