Backup SIM cards for reliable internet
With a backup SIM card from iotDiscount, your organization remains connected when the primary internet connection fails. Insert the SIM card into a 4G or 5G router and let the router automatically switch to mobile internet in the event of an outage, maintenance work, or a problem with the fixed connection.
You choose the backup connectivity that suits your application: a cost-effective usage-based IoT SIM card, a SIM card on the Vodafone or Odido network, a solution with a public IPv4 address, or a combination of multiple mobile networks. Mobile backup is widely used to automatically take over when a fixed connection fails.
Why a backup SIM card?
Internet outages have a direct impact on business processes. Consider payment terminals, cash registers, cloud telephony, security cameras, alarm systems, remote access, workstations, machine control, and communication with locations or vehicles.
A backup SIM card provides an additional connection alongside your primary internet line. Your router monitors the main connection and automatically switches to 4G or 5G in the event of a failure. As soon as the fixed connection is available again, the router can switch back to the normal WAN connection.
This makes a mobile backup SIM card suitable for, among other things:
- Offices, shops and hospitality locations
- Construction sites and temporary workplaces
- PIN and POS systems
- Security cameras and alarm systems
- 4G/5G routers and SD-WAN solutions
- Industry, energy and remote monitoring
- Vehicles, mobile service units and emergency locations
- Primary internet connections where no fixed line is available
IoT backup SIM card: low fixed costs
For many applications, an IoT backup SIM card is the most cost-effective choice. You pay a fixed monthly cost of just €0.50 per SIM card per month, supplemented by the actual data usage per GB.
This setup is ideal when the SIM card is normally in standby mode and only consumes data during a malfunction or as a temporary connection. This means you do not pay for a large data bundle that remains unused, but you do keep a reliable mobile connection at your disposal.
An IoT backup SIM card is suitable for, for example:
- Failover of fixed internet connections
- Security, alarm response and camera connections
- Monitoring of installations and technical equipment
- IoT and M2M equipment with low or variable power consumption
- Temporary internet access during installation or delivery
- Backup connections in 4G and 5G routers
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.
