You will also discover how fixed IP SIM cards contribute to enhanced security, simplified device management, and overall network reliability. Whether you are new to the concept of static or fixed IP IoT sim cards or you are involved in industrial automation, retail, healthcare, or any other sector that depends on unwavering connectivity, this guide provides comprehensive insights and real-world examples to help you make informed decisions about your IoT connectivity strategy.
Moreover, with perspectives drawn from industry-leading sources, this resource equips you with the knowledge to future-proof your deployments and stay ahead in an increasingly connected world.
What is a fixed IP SIM card?
A fixed public IP SIM card or static private IP SIM card is assigned a specific Internet Protocol (IP) which doesn’t change. This contrasts with typical mobile devices which are assigned a dynamic IP address. This means that the IP address can change every time the device connects to the mobile network.
Static private IP SIM cards are typically used with IoT devices because a consistent stable connection is required and allows the operator to always be able to securely access the device remotely without compromising the network.
The SIM cards are assigned a specific Internet Protocol (IP) address that remains constant, unlike dynamic IP addresses which can change with each network connection.
This static address is crucial for:
- Reliable remote access
- Consistent data transmission
- Robust network security
- Simplified device management
Types of fixed IP SIM cards
In the world of fixed IP SIM cards, there are two primary categories:
Fixed public IP SIM cards
Fixed public IP SIM cards are assigned a static address that is accessible via the public internet. They are ideal for devices that need to be reached across multiple locations, such as:
- CCTV cameras
- Point-of-sale (POS) systems
- Smart meters
This feature is crucial for centralised management, remote troubleshooting, real-time monitoring, and data retrieval, enabling efficient operations and enhanced control over distributed systems, making them indispensable for global connectivity and monitoring.
Static private IP SIM cards
Static private IP SIM cards operate solely within a private network, providing an added layer of security by ensuring the IP address is not exposed to the public internet. This approach is beneficial in sensitive environments like:
Healthcare systems Financial institutions Industrial automation
Their use restricts access to authorised users only, lowering the risk of cyber threats, this segregation from the public domain helps shield sensitive information and devices from unauthorised access or external threats, significantly enhancing the overall safety and security of the network infrastructure.
Fixed IP vs dynamic IP SIM cards
Understanding the differences is key. The table below compares these two types:
| Feature | Fixed IP SIM card | Dynamic IP SIM card |
|---|---|---|
| IP address assignment | Assigns a specific, unchanging IP address to the device. | Assigns dynamic or changing IP addresses to the device. |
| Consistency | Offers consistent connectivity. | Connectivity can vary due to changing IPs. |
| Device accessibility | Simplifies device management and remote accessibility | Remote access is more complex due to IP variability. |
| Security | Permits tailored, IP-based security controls. | Requires additional security measures because the IP is not static. |
| Use cases | Best for critical applications like industrial IoT, CCTV, and remote monitoring. | Typically used in consumer applications (e.g. smartphones) where fixed access is less critical. |
Additional insights on fixed IP connectivity
How can I get a fixed IP?
To obtain a fixed IP SIM card:
- Contact an IoT connectivity provider: Companies like Cellhire offer tailored packages that include fixed IP configurations.
- Specify your requirements: Clearly communicate the need for a permanent IP to ensure proper provisioning.
- Review service plans: Fixed IP plans can differ in pricing and contracts compared to dynamic options, so it’s important to select one that meets your needs.
Do phones have a fixed IP?
No! Typically, smartphones are assigned dynamic IP addresses, which change with each connection. Fixed IP addresses are generally reserved for dedicated IoT devices or specialised enterprise solutions where a constant IP is necessary for stability and security.
What are 4G fixed IP SIM cards?
The evolution of cellular technology now includes 4G fixed IP SIM cards. These combine:
- High-speed data transmission: Essential for real-time applications like telematics and video surveillance.
- Fixed IP stability: Ensuring that even on a fast 4G network, devices benefit from a permanent IP address.
This dual capability is particularly valuable in environments where both speed and reliability are imperative.
Operator-specific fixed IP SIM insights
Do operators like Three, Vodafone, O2, and EE offer fixed IP SIM cards?
Many enterprises ask whether major mobile operators provide fixed IP SIM cards. Here’s what is known based on industry research and provider information:
- Three: Offers fixed IP SIM options within their business and IoT service plans, while standard consumer packages use dynamic IPs.
- Vodafone: Includes fixed IP capabilities as part of custom connectivity arrangements, known for its extensive IoT solutions.
- O2: Features fixed IP options tailored for enterprise applications, although most offerings for individual consumers are dynamic.
- EE: Incorporates fixed IP SIM cards in specialised IoT products to deliver robust connectivity, particularly for secure and critical systems.
For an accurate assessment, it’s recommended that businesses contact these operators directly or work with a globally recognised aggregator like Cellhire, which integrates connectivity options across multiple networks and ensures you receive a solution tailored to your specific requirements.

What are the benefits of fixed public and static private IP SIM cards?
Fixed public and static IP SIM cards are the preferred choice over a dynamic IP SIM card in a range of scenarios and applications due to several key benefits that they offer:
Fixed IP SIM cards offer increased security
Fixed IP SIM cards offer a higher level of security compared to dynamic IP SIM cards. This is because fixed IP SIM cards provide a constant and unchanging IP address, making it more difficult for cyber attackers to infiltrate the network and cause harm.
In contrast, dynamic IP SIM cards assign a new IP address every time the device connects to the network, which may create vulnerabilities and increase the risk of cyberattacks and other harmful intrusions. Therefore, businesses and individuals who prioritise security may choose to opt for fixed IP SIM cards to ensure a safer and more secure network environment.
Fixed IP SIM cards are more stable and reliable
If you are using an application that requires a reliable and uninterrupted connection, like in the case of remote monitoring, fixed IP SIM cards can be a great option.
The SIM cards ensures that your device is assigned a particular and unchanging IP address, which means you always know how to locate and connect to it. This consistent connection ensures that you are not faced with any unexpected downtime or interruptions, which can be critical in situations that require continuous monitoring and real-time data transfer.
Fixed IP SIM cards offer the ability to access and control the device remotely
Fixed IP addresses play a vital role in enabling remote access and control of various devices, including but not limited to surveillance cameras, IoT devices, or remote sensors. With a fixed IP address, these devices can be easily accessed and controlled from afar, without the need for constantly changing connection settings.
This consistency in address simplifies connectivity and management, allowing for seamless and hassle-free monitoring and control of these devices.
In addition to the benefits mentioned above, here are some more enhanced benefits:
- Improved scalability: Fixed IP SIM cards streamline the process of adding or managing devices at scale, ensuring uniform connectivity across vast networks.
- Customised network configurations: Advanced solutions now allow for the integration of fixed IP SIM cards with customised firewall settings and VPN/IPSEC options for heightened security.
- Future-ready connectivity: As IoT deployments grow, the ability to maintain a consistent IP address is foundational to supporting emerging technologies and ensuring compatibility with next-generation applications.
These enhancements underscore the growing importance of fixed IP connectivity in modern IoT strategies.
