In this Help Centre section you will find the most important information about setting up and using our M2M SIM cards.
In our Help Center you will find instructions and all necessary information for commissioning and using our M2M SIM cards. Please note that we sell different M2M SIM cards. Please check which of our two SIMs - data+ or tech+ - you are using and select the appropriate help area accordingly.
Have you received one of our M2M test SIM cards? Then please write us a short message with your name, e-mail address and the number from the outer cover of the SIM(s) to sales@whereversim.de. We will then set up access for you to our online portal, where you can activate and manage the test SIM.
For the SIM cards to work in the end devices, please set the APN "wsim" and activate the"data roaming" option. A username, password or PIN is not required. More about this in the Help Center.
Frequently asked questions about our M2M SIM card and IoT projects
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.
Currently, our M2M SIM cards support 2G (GSM/GPRS/EDGE), 3G (UMTS/HSDPA/HSPA+), 4G (LTE/LTE Advanced) and LTE-M technologies. We also already support 5G in some countries. We are currently still negotiating with network operators about the use of NB-IoT and a larger 5G coverage. As soon as the negotiations are concluded, you will be able to use NB-IoT and 5G with the M2M SIM cards already in use or installed without having to exchange them. With our M2M SIM, you are also optimally equipped for future technologies.
Unlike network operator SIM cards our M2M SIM cards are not tied to a specific mobile network. Instead, our SIM cards always allow your devices to connect to the strongest available network at the respective location. Worldwide, devices that meet the minimum technical requirements can log into over 485 mobile networks with our M2M SIM. Our M2M SIM cards support multiple networks from different network operators, such as Telekom or Vodafone, at one location with just one tariff.
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.
Generally, M2M SIM cards will work in any router, but retail routers are not designed for professional use and can cause malfunctions, downtime, and thus unnecessary costs.
For a fast, stable and above all secure operation of you IoT devices, we recommend M2M routers optimized for business and industrial use. With our PreConfig package, we offer preconfigured routers with which you can bring your devices online fast and easy via plug & play.
