Frequently asked questions about our M2M SIM card and IoT projects

Is there a difference between an IoT and an M2M SIM card?

No, there is no real difference between an M2M SIM card and an IoT SIM card. Both SIM cards have the same task: they enable different end devices and machines to access the mobile network so that they can transmit data as part of M2M (machine-to-machine) communication or IoT applications.

Which mobile radio standards does the M2M SIM card support?

On a technology level, our M2M SIM cards support 2G (GSM/GPRS/EDGE), 3G (UMTS/HSDPA/HSPA+), 4G (LTE/LTE Advanced), 5G as well as LTE-M and NB-IoT technologies. Depending on roaming contracts, however, not every transmission technology is available in every country. As soon as new mobile networks are included in our coverage, you will be able to use the added networks and technologies such as NB-IoT and 5G with the already deployed or installed M2M SIM cards without replacement. You are also well equipped for future technologies with our M2M SIM.

Which cellular network does the M2M SIM card connect to?

Our M2M SIM cards - unlike consumer SIM cards from network operators - are not tied to a specific mobile network. Instead, they give your IoT devices access to all available mobile networks at the respective location via national roaming. Worldwide, devices that meet the minimum technical requirements can log on to over 485 mobile networks with our M2M SIM. In Germany, our M2M SIM cards support all mobile networks of the three network operators Telekom, Vodafone and o2 with just one rate.

Why can the M2M SIM card use different mobile networks?

Basically, this is similar to the situation with the SIM card in a smartphone when abroad: Due to roaming agreements between domestic and other network operators, SIM cards abroad are allowed to use the network of another network operator.

For our M2M SIM cards and tariffs, we have concluded these agreements with a very large number of network operators in order to be able to offer our customers data at affordable costs all over the world. Worldwide, more than 485 mobile networks in over 189 countries are available to our M2M SIMs, in which we can also offer low-cost M2M tariffs for even high data volumes.

Which routers are most suitable for the use of M2M and IoT SIM cards?

In general, our IoT SIM cards will work in any router. However, commercially available routers are usually not designed for professional use and may cause malfunctions or downtime, resulting in unnecessary costs.

For fast, stable and above all secure operation, we recommend M2M routers optimized for commercial and industrial use. With our PreConfig package, for example, we offer you preconfigured M2M routers with which you can bring your devices online very simply - plug & play.

If you need further assistance in selecting the right hardware, our M2M experts will be happy to help.
