IoT SIM cards with fixed public IPv4 address
Direct remote access, without changing IP address
Do you want to be able to remotely access a router, camera, machine, PLC, alarm system, or other IoT device via the mobile network? With an IoT SIM card with a fixed public IPv4 address, every device receives its own permanent, publicly accessible IP address.
Unlike a standard mobile SIM card, where the IP address often changes dynamically and traffic is usually behind Carrier-Grade NAT (CGNAT), the IPv4 address remains the same with this solution. As a result, your device is directly accessible via the internet at a known IP address, even after a restart, a temporary network interruption, or moving the SIM card to other compatible hardware. A fixed public IPv4 solution is ideal for professional remote access, remote management, and applications where IP whitelisting is required.
When do you choose fixed public IPv4?
A fixed public IPv4 address makes it possible to establish a connection directly to your mobile router, modem, or IoT device from an authorized internet connection. You do not need to determine the current IP address of a device every time and are not dependent on an outgoing cloud connection or dynamic DNS solution.
These SIM cards are suitable for, among others:
- 4G and 5G routers at temporary, mobile, or remote locations
- Camera surveillance, video streaming and mobile CCTV setups
- PLCs, HMIs, data loggers and industrial controls
- Energy installations, pumps, generators and technical installations
- Remote service and maintenance of machines
- Construction sites, event venues and temporary internet connections
- Digital signage, kiosks and payment terminals
- Alarm, access control and security systems
- Maritime, transport and vehicle applications
- Equipment for which an external party must whitelist a fixed IP address
A practical example: a service technician can securely log in to a Teltonika or Peplink router at a remote location via the fixed IP address. Subsequently, he or she can access the connected PLC, camera, or local network equipment without anyone needing to be present on site.
KPN 5G met vast IP Vodafone LTE-back-up
For locations where continuous internet is essential, iotDiscount offers a redundant mobile internet solution with two different Dutch networks. You use an iXT SIM card as the primary connection via the KPN network, with a fixed public IPv4 address for remote reachability. As a second connection, you insert a Vodafone LTE SIM card into the router as an automatic backup.
- This combination is suitable for locations without a fixed internet connection, temporary locations, and business-critical applications where an additional mobile network connection is desired.
Odido Business backup SIM card
For a powerful mobile backup connection, iotDiscount offers an Odido Business backup SIM card with a generous Fair Use Policy of 2.5 TB per month. The SIM card is compatible with 4G and 5G routers and provides a reliable fallback connection when your fixed internet connection is temporarily unavailable.
The subscription has a term of 12 months and is intended for business use in the Netherlands. You pay a fixed amount per month and have a very generous data bundle for failover, temporary internet access, or a mobile primary connection where no fixed line is available.
Optional fixed public IPv4 address
- Does on-site equipment need to be accessible from the internet? Then this Odido Business SIM card is also available with a fixed public IPv4 address.
Backup SIM card with public IPv4 address
For applications that need to be accessible from the internet, a standard mobile data SIM card is not always sufficient. Many mobile connections use CGNAT. As a result, incoming traffic from the internet usually cannot be forwarded directly to your router, camera, PLC, or other equipment.
With a backup SIM card with a public IPv4 address, you can make equipment remotely accessible. This is particularly relevant for management, monitoring, remote service, VPN connections, cameras, and applications where inbound connections are necessary.
A public IPv4 address can be used for, among other things:
- Remote management of 4G and 5G routers
- Access to cameras, recorders, and alarm systems
- VPN servers or external VPN access
- Remote service of industrial machines and PLCs
- Monitoring platforms that require an incoming connection
- Connections with fixed IP whitelists
A public or fixed IP is not necessary in every situation. If your router or device works exclusively with outgoing cloud, VPN, or MQTT connections, a standard data SIM card is often sufficient. For applications involving remote access or incoming connections, we recommend assessing in advance whether public IPv4, a private APN, or a VPN solution is the best choice. A public fixed IP option can enable remote access to a router and connected IoT devices.

An IoT SIM for every device and every deployment
Choose a standard IoT SIM (UICC) with a single profile for simple and reliable connectivity, or choose an IoT eSIM (eUICC) for maximum flexibility and future-proofing. With an eSIM, you can remotely change the network profile whenever your coverage, application, or deployment requires it.
Whatever choice you make, IoT Discount helps you with the right SIM configuration, connectivity, and technical support for your IoT or M2M project.
Still not sure about the correct SIM form factor?
Have you already selected your devices? Then the required SIM form factor is usually already known. If you are starting from scratch, we are happy to help you choose the right version for your hardware and application.
IoT Discount IoT SIM cards are available as mini-SIM (2FF), micro-SIM (3FF), nano-SIM (4FF), and eSIM (eUICC). Combine the right form factor with local, European, or global connectivity and ensure your device is correctly connected from the start.
Integrated SIM (MFF2)
Do you want to integrate connectivity directly into your production process? The MFF2 embedded SIM is soldered directly onto the printed circuit board and is ideal for compact, rugged, and hard-to-reach IoT devices.
This fixed SIM solution saves space, prevents loose contact points, and offers extra protection against vibrations, moisture, and tampering. Ideal for sensors, trackers, industrial equipment, and other devices that need to remain reliably connected for extended periods.
Multi-format SIM card (2FF, 3FF and 4FF)
Do you want easy access to your devices after installation and a practical, affordable SIM solution? Then the classic multi-format IoT SIM card is an excellent choice.
Simply choose the right size — mini-SIM (2FF), micro-SIM (3FF), or nano-SIM (4FF) — pop it out of the card, insert it into your device, and connect. A reliable and simple solution for a wide range of IoT and M2M applications.
