What it is

Most mobile SIMs give the router a private address behind the network's address translation, so nothing can connect in. A fixed IP SIM gives a public static address you can reach from anywhere. A private APN gives fixed private addresses on a closed network, reachable only from your own systems.

Where it fits

  • Viewing NVRs and cameras directly
  • SCADA and telemetry systems that poll devices
  • Remote access for engineers without a VPN service

What to look for

  • Public fixed IP or private APN
  • Firewall rules to restrict who can connect
  • Whether a VPN or RMS would be simpler

Questions

Is a fixed IP SIM secure?

It is as secure as the router's firewall rules. Restrict access to known addresses and use strong passwords, or use a private APN for closed networks.
