Need a fixed IP SIM card for secure, reliable access to your IoT sensors and devices? You’re in the right place. Smooth Connectivity offers both public and private fixed IP SIMs, enabling you to remotely access your devices over a VPN no matter where in the world they are.
A fixed IP SIM card assigns a static IP to your device, allowing you to send and receive data packets consistently without IP changes. This is essential for applications where remote control, static addressing, and stable communication are required.
Perfect for 4G / 5G router, Cradlepoint devices, and connected assets using 4G or 5G antennas, fixed IP SIMs also play a key role in industrial networks where knowing what is cellular data and backhaul meaning in networking is critical to performance and uptime.
Fixed IP’s are almost always a requirement for CCTV monitoring, enabling users to remotely live stream.
It’s common for alarm receiving centres (ARC) to require fixed IP SIMs to gain remote access.
Rather than going to site, fixed IP SIMs can allow users to remotely access routers to make changes or updates to config.
Remotely update advertising on digital signage by access devices through fixed IP SIMs.
Receive data and control energy devices, such as wind farms via fixed IP SIMs
Instantly view live footage of vehicle CCTV in the time of need through Fixed IP M2M SIMs.
With seamless roaming across 370+ networks, our fixed IP solution supports devices across all SIM card sizes delivering secure access within your IoT network, while maintaining performance across varying frequency bands (yes, even for those wondering what is frequency).
Consistent Remote Access – Always reachable, perfect for remote management of IoT sensors, 4G / 5G routers, and Cradlepoint devices
Global VPN Integration – Secure, private communication via VPN from anywhere in the world
Reliable Data Flow – Send and receive packets without interruption due to changing IPs
Optimized for Industrial Use – Compatible with 4G antennas, 5G antennas, and smart networking environments where knowing backhaul meaning in networking matters
Ideal for static monitoring, CCTV, smart meters, and connected infrastructure

Need reliable remote access to your IoT devices or routers? Fixed IP SIM cards keep your connection stable, secure, and easy to manage. This FAQ covers the essentials from VPNs and cellular data to SIM sizes, 5G antennas, and more.
A fixed IP SIM card is a special type of SIM that provides a static (unchanging) IP address. This makes it ideal for remote device access, especially in IoT networks where consistency and security are vital. It allows you to connect to the same device at the same IP every time no dynamic IP changes to deal with.
IoT sensors collect data from their surroundings and send it over the cellular network. A fixed IP SIM ensures the data packets from these sensors can be reliably accessed from anywhere. This is essential for remote monitoring, control, or troubleshooting whether it’s a smart meter or an environmental sensor.
In networking, a packet is a small chunk of data sent across a network. When using a fixed IP SIM, packets travel from your IoT device to your server (and back) using that fixed IP, ensuring predictable routing and more stable connections.
Frequency refers to the radio waves used by cellular networks to transmit data. Different bands (like 700 MHz or 3500 MHz) offer varying speeds and coverage. High frequencies may support faster speeds but shorter ranges, which is important to consider when choosing a 5G antenna or 4G antenna for your setup.
Choosing between private and public IoT networks impacts everything from security to efficiency. Learn how private APNs, static IPs, and dedicated infrastructure help ensure scalable, secure, and high-performance IoT deployments while understanding where public options may still be the right fit.
In smart cities and remote infrastructure, using a public IP address for IoT devices enables direct, secure, and efficient access from anywhere. From traffic management and smart lighting to energy control, flood monitoring, noise pollution tracking, and smart parking, a public IP unlocks real‑time insights and control perfect for enterprises that need high availability and remote responsiveness.
Strong and reliable cellular signal is essential—not just for smartphones, but also for the growing ecosystem of IoT (Internet of Things) devices. Whether you’re managing a fleet of smart meters, deploying sensors in remote areas, or simply trying to get better reception on your phone, improving cellular signal can significantly enhance performance and reliability.
