Frequently Ask Questions

Q: Most cellular carriers use CGNAT, assigning private IPs. How can I remotely access my PLC connected to this router?

A: This is a common problem with regular SIM cards. Our routers natively support robust IPsec VPN tunneling which will allow you to get around CGNAT and create a secure inbound connection to your remote equipment. By configuring the router as an IPsec VPN client that connects back to your central server, you create a secure, persistent tunnel that completely bypasses carrier NAT restrictions, and provides enterprise-grade encryption for your OT data.

Q: How does the “4G/Wired Smart Backup” ensure my SCADA network stays online?

A: The router is constantly checking your primary internet connection. When the WAN port goes down, the 4G/wired smart backup function automatically and immediately switches the traffic to cellular 4G network. “Once the wired connection is back, it seamlessly switches over the data and keeps the production line running without missing a beat.”

Q: Is the router locked to a specific carrier, and what frequency bands does it support?

A: Our routers are compatible with a standard Medium SIM card and are carrier-unlocked, so any operator’s SIM card will work. The VT-LTE400 features a 4G CAT1 module optimized for South Asia, Europe, the Middle East and Africa , with native support for key bands including LTE-FDD B1, B3, B5, B7, B8 and B20 for reliable, wide-area coverage.

Q: Do you offer a 5G or high-bandwidth version of this industrial router?

A: VT-LTE400 is a product specifically designed for 4G CAT1. It has a transmission rate of 10Mbps down and 5Mbps up. CAT1 provides the ideal combination of ultra-reliable connectivity, low power consumption and cost-effectiveness for over 95% of industrial SCADA, telemetry and PLC monitoring applications.
