What is a Fixed IP SIM?

A Fixed IP SIM, also known as a Static IP SIM, assigns a consistent IP address to your device. This allows it to be accessed remotely at any time without the IP changing.

This is essential for applications where you need to:

  • Remotely access routers and network equipment
  • Connect to CCTV and security systems
  • Manage remote infrastructure
  • Maintain persistent connections to devices

Unlike standard mobile SIMs, which use dynamic IP addressing, a Fixed IP SIM ensures your devices remain accessible in a predictable and controlled way.

Public Fixed IP Private Fixed IP

Why Private Fixed IP SIM is More Secure

Private fixed IP SIMs reduce exposure to external threats by keeping devices off the public internet. This helps protect against:

  • Unauthorised access attempts
  • Port scanning
  • Automated attacks
  • Vulnerabilities in exposed devices

Access is controlled through a secure connection, ensuring only authorised users can reach the device.

How Fixed IP SIM Enables Remote Access

Devices are not publicly exposed. Instead, users connect via KeySecure VPN, which provides controlled access to devices on the private network. This allows you to:

  • Remotely log into routers and devices
  • Access CCTV and security systems
  • Manage remote networks and infrastructure
  • Maintain secure connections to field equipment

Access can be structured using VPN groups, allowing you to control which users can access specific devices or sets of SIMs — separating different sites, customers or deployments within the same environment.

Fixed IP SIM Use Cases

Fixed IP SIMs are used wherever consistent, secure remote access matters more than just connectivity.

📹

CCTV & Surveillance

Access live and recorded footage from cameras in the field without exposing systems to the public internet or relying on changing IP addresses.

🔔

Alarm & Security Systems

Maintain reliable, secure connections to alarm panels, access control systems and security infrastructure across multiple sites.

🖥️

Remote Router Management

Log into and configure routers and network equipment in remote locations without requiring an engineer on site.

🏭

Industrial Equipment

Monitor and manage machinery, PLCs and industrial systems remotely with secure, persistent access to field devices.

🖼️

Digital Signage

Manage and update digital displays remotely across retail estates, venues and public spaces with reliable fixed IP access.

💳

EPOS & Payment Systems

Keep payment terminals and EPOS systems securely connected and remotely accessible for support and management.

Fixed IP SIM vs Standard Mobile SIM

A standard mobile SIM uses dynamic IP addressing, which makes reliable remote access complex. A Fixed IP SIM removes those limitations.

Fixed IP SIM — Frequently Asked Questions

Common questions about fixed IP SIM cards and secure remote access.

A Fixed IP SIM, also known as a Static IP SIM, assigns a consistent IP address to your device so it can be accessed remotely at any time without the IP changing. Unlike standard mobile SIMs that use dynamic IP addressing, a Fixed IP SIM ensures your devices remain accessible in a predictable and controlled way.

A private fixed IP SIM places devices on a private network, not directly accessible from the public internet, and accessed securely via VPN. A public fixed IP SIM exposes devices directly on the public internet via their IP address. For most business and IoT deployments, private fixed IP is the recommended option due to significantly higher security. Read more about public vs private fixed IP.

With a private fixed IP SIM, devices are not publicly exposed. Users connect via KeySecure VPN, which provides controlled access to devices on the private network. Access can be structured using VPN groups, allowing you to control which users can reach specific devices or deployments — separating sites, customers or project types within the same environment.

Fixed IP SIMs are commonly used for CCTV and surveillance systems, alarm systems and security infrastructure, remote router management, industrial equipment monitoring, digital signage, EPOS and payment systems, and remote IT infrastructure — any deployment where secure, consistent remote access is required.

Private fixed IP SIMs keep devices off the public internet, reducing exposure to unauthorised access attempts, port scanning, automated attacks and vulnerabilities in exposed devices. Access is controlled through a secure VPN connection, ensuring only authorised users can reach the device.
