Features and advantages of our M2M SIM card

National Roaming

In the European Union, our M2M SIM card allows your device to log into any mobile network via national roaming, e.g. Telekom, Vodafone and o2 in Germany.

Free Network Selection

With a wherever SIM, your devices are allowed to automatically connect to the strongest network in each location - because unlike M2M SIM cards from network operators, our M2M SIM does not favour any particular network.

Worldwide Use

You can choose from more than 485 networks in 205+ countries for your project. In border areas, our M2M SIM cards also include networks in neighbouring countries.

Supported Technologies

Always The Fastest Speed

We do not throttle. You use the fastest possible speed on site at all times. We support 2G (GSM/GPRS/EDGE), 3G (UMTS/HSDPA/HSPA+), 4G (LTE/LTE Advanced) and LTE-M technologies. We can also already offer 5G in some countries. We are currently agreeing on the use of NB-IoT and even greater 5G coverage with the network operators.

Always the best network

LTE-M (LTE Cat M1)

LTE-M is particularly suitable for devices that have to save electricity or are difficult to reach e.g. behind walls. Many network operators worldwide support this technology already and more are joining every week. Feel free to contact us for more details.

Data, SMS (and Voice)

As standard, our M2M SIM cards support data transmissions and SMS, voice calls on request.

Security from and at wherever SIM

We know that with our M2M SIM cards we are an important part of your IoT projects and infrastructure. That's why security and reliability are our top priorities.

APN, VPN and static IP addresses

If you wish, we can provide you with your own private IP subnet (a private APN). Access to the M2M SIM cards is therefore only possible via a secure IPsec VPN connection and protected from third parties.

On request, we also offer you the option of accessing the SIM and device via a protected VPN using a static private IP address of the M2M SIM. For secure and easier remote access, we also offer OpenVPN on request.

VPN, APN and static IP addresses
Redundancy

99,99 % availability through complete geo-redundancy of our data centers and a state-of-the-art architecture based on microservices.

IMEI-Lock

Restrict the use of a SIM card to a specific device based on the IMEI (unique identification number of a mobile phone device).

2-Factor-Authentication

Double protection when logging into the online portal: 2-factor authentication protects your data in the wherever SIM portal from unauthorised access.

Frequently Asked Questions

Why can the device automatically connect to the best local mobile network?

Due to our roaming agreements, your device with our M2M SIM cards is allowed to log into over 400 mobile networks worldwide. In Germany, for example, the networks of all network operators (Telekom, Vodafone and o2) are supported. Since our SIM cards do not favour any network operator, your device is allowed to dial into the best available network locally from the SIM card side. Your hardware only needs to be configured accordingly for this.

Why can the SIM card use so many networks of different network operators?

Due to roaming contracts, our SIM cards are allowed to connect to different networks – similar to the way your mobile phone would do if you were abroad. The difference is, however, that even high data volumes are cheap in many countries due to our good contractual conditions with local network operators.

Can I freely choose the mobile network that the M2M SIM card uses?

Yes, our M2M SIM is designed to use different networks, but it can also use only one specific network if supported by the hardware. A corresponding manual configuration of the network is possible on most end devices. By default, our M2M SIM is designed to enable your device to connect to the strongest mobile network at each location. Unlike network operators, we do not tell your device which network to use.

Can I set a limit for data consumption? And what happens when the set data limit is used up?

Yes, you can set a data limit (e.g. 500 MB per SIM card per month) for your M2M SIM cards in the customer portal. You can also group SIM cards and set a different data limit for each group. If a set data limit is used up, we block the data traffic for this SIM card until the end of the month. You will also receive a notification in the portal when the limit is reached.

Do I need to change SIM cards to use 5G or NB-IoT?

No, our SIM card is future-proof. In some countries we already support 5G, which already used M2M SIMs can also use. As soon as we have greater coverage for 5G or support NB-IoT, these technologies will also be supported by SIM cards already installed. It is not necessary to replace inserted SIM cards.

Does the SIM card support Voice?

We offer M2M SIM cards both with and without telephony. Please contact us if telephony is relevant for your use case.
