Over 1,500 companies worldwide rely on WhereverSIM
Whether it's a festival, trade show, concert, or sporting event, a stable internet connection is essential for ensuring that events run smoothly today. Tickets must be verified, payments processed, and systems managed centrally.
The good news is that many of these challenges can be avoided from the start with the right connectivity solution.


Whether it's a sporting event or a concert, your focus is on the attendees, exhibitors, booths, and ensuring that everything runs smoothly on site. Just as it should be.
Events place special demands on connectivity. That is why event organizers, trade show builders, and event service providers rely on a mobile connectivity solution that combines maximum availability with easy management.
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 over 189 countries for your M2M project. Near borders, devices automatically connect to networks in neighboring countries.
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.
Whether it’s a festival, trade show, sporting event, or concert: Modern events rely on a reliable data connection. If the connection goes down, ticket scanners stop working, card payments are declined, or sales booths lose access to their systems.
But especially when thousands of visitors are on-site at the same time, traditional mobile network solutions quickly reach their limits. That’s why, with WhereverSIM, organizers and event service providers rely on a mobile connectivity solution that automatically connects to the strongest available network and ensures maximum availability even under heavy load.
This leaves you with more time to focus on your event instead of troubleshooting.

Unlike consumer SIM cards from network operators, our M2M SIM cards are not tied to a specific mobile network. Instead, they enable IoT devices to access all available mobile networks at their respective locations via national roaming. Since our M2M SIMs are set to unmanaged roaming by default, they allow devices to connect to the strongest mobile network at their location rather than to that of a preferred carrier.
Worldwide, devices that meet the minimum technical requirements can connect to over 485 mobile networks using our M2M SIM card. In Germany, our M2M SIM cards support all mobile networks operated by the three carriers—Telekom, Vodafone, and o2—with a single plan.
Our M2M plans typically M2M plans a one-month term and are automatically renewed for another month as long as you have active SIM cards from us in use. You are generally free to decide when a SIM card is activated or deactivated. You will not be charged until the SIM card is activated. If an M2M SIM is deactivated during a given month, you will no longer be charged for it starting the following month.
SIM cards that are not needed immediately can be stored in an inactive state for as long as you like without incurring any fees. We do not automatically activate or deactivate them.
Yes, that’s possible. With all of our M2M plans, you can pause individual, multiple, or even all of the SIM cards you’re using at any time, free of charge, and you’ll no longer be charged a monthly fee starting the next calendar month. Reactivating the SIM card(s) is also free of charge. You can pause the SIM cards yourself through our online portal.
No, our SIM cards are intended exclusively for use by businesses. We do not sell them to private individuals, either as individual SIM cards or in bulk. The M2M SIMs, however, are suitable for businesses of all sizes and across all industries.
Yes. Modern LTE and 5G networks enable reliable live streaming, even with high-resolution video formats. In addition to data plans without throttling, a stable mobile connection is essential. Our M2M SIM cards provide this stability to end devices through non-steered roaming. This means the device can connect to the strongest local mobile network without prioritizing a specific carrier.
Yes. If you’re operating devices in different locations at the same time, the WhereverSIM Portal lets you keep track of your active SIMs and devices at all times.
