Over 1,500 companies worldwide rely on WhereverSIM
M2M SIM cards are specifically designed for connecting devices. They ensure that machines, systems, and IoT devices can reliably transmit data via mobile networks, even at different locations or abroad.
Unlike traditional SIM cards, M2M SIMs use multiple mobile networks—even within a single country—and thus benefit from better network coverage.

Access to multiple mobile networks within a country (national roaming), e.g., in Germany: Telekom, Vodafone, and o2.
Thanks to network roaming, you always have access to the strongest mobile network in your location by default, regardless of the carrier.
>485 networks in 189+ countries for your M2M project. You can also use networks in neighboring countries near the border.
No throttling. The fastest possible local speed at all times.
As standard, our M2M SIM cards support data transmissions and SMS, voice calls on request.
Through the WhereverSIM portal, you can centrally manage your SIM cards, monitor connections in real time, and keep track of data usage and device status at all times.
From activating individual SIMs to integrating them into your own systems via API—the platform helps you manage IoT connectivity easily and efficiently.
Keep track of data usage, connection status, and device status at all times. Custom limits and alerts help you identify anomalies early on and keep costs under control.
Security is a key component of reliable IoT connectivity. To protect your data and devices, we offer:
Different IoT applications have different requirements. That’s why WhereverSIM offers flexible M2M plans, suitable for everything from a single device to a large fleet of devices.


With WhereverSIM, you no longer have to worry about connectivity, leaving you free to focus on what really matters.
Whether you're deploying your first devices locally or rolling them out internationally, WhereverSIM ensures that your IoT devices stay reliably connected.
Start locally and scale globally:
Whether Mini (2FF), Micro (3FF), Nano (4FF), or Embedded (MFF2): Our SIM cards are available in all formats, in both standard and industrial versions.

Our M2M SIM cards are not restricted to one network operator, but can also connect to different mobile networks within a country (national roaming). The end device itself checks the available networks and connects to the best network depending on the signal strength. This means that your devices remain flexible and practically always have a stable connection.
Our M2M SIMs have access to a global network of roaming partners. This means that your devices can connect to us in over 485 mobile networks in more than 190 countries. Because the SIMs are not tied to one provider, your device chooses the best network itself - for maximum coverage and reliability.
Yes, our M2M SIM is designed to use different networks, but it can also only use a specific network if it is supported by the hardware. The network can be configured manually on most end devices. By default, our M2M SIM is designed to enable your device to connect to the strongest mobile network at any location.
Yes, you can define individual data limits for each SIM card. If the data volume is exceeded, the card can be automatically deactivated, throttled or monitored via an alarm message - depending on which option you prefer. This gives you full cost control and prevents unwanted excess consumption.
No, our M2M SIM cards are already compatible with all common network standards - from 2G to 3G, 4G (LTE), LTE-M through to NB-IoT and 5G. A physical exchange is not necessary, provided your device supports the desired network technology and this is activated in your tariff.
Our M2M SIM cards are designed for pure data communication as standard. However, voice services can be activated on request - for special applications in industry or the security sector, for example.
Our industrial-grade SIM cards are designed for long-term use. Depending on the form factor and operating conditions, they can be operated for up to 10 years or longer without any problems - ideal for long-lasting devices and projects that require no maintenance.
Our minimum purchase quantity is 25 SIMs - but we will be happy to find flexible solutions with you if your IoT project has other requirements. We tailor our tariffs to you: many can be terminated on a monthly basis or can be individually adapted to your project duration.
With our WhereverSIM portal, you have full transparency at all times: you manage your cards centrally, monitor data volumes, set limits, activate or deactivate cards in real time and receive notifications for certain events - which can also be integrated via API.
Naturally. We will be happy to provide you with a tailor-made offer based on your project size, requirements and desired network technologies. Simply use our contact form or give us a call.
