IoT SIM cards with voice
Reliable mobile communication for devices that need to be able to make calls
Not every IoT device communicates exclusively via data. For applications such as elevators, alarm systems, SOS buttons, access control, intercom systems, and technical emergency detectors, it is important that a device can also make calls via the mobile GSM network. The IoT SIM cards with voice from IoTDiscount combine mobile data, SMS, and voice in a single business M2M solution.
The SIM card operates via regular mobile networks, just like a mobile phone. As a result, a device can not only send data to a platform or control room, but also make outgoing calls to a pre-set phone number or alarm center. This is ideal when a data connection alone is insufficient and direct, audible communication remains necessary.
Greater range thanks to non-steered roaming
A standard mobile SIM card is often linked to a single provider or a single preferred network. This is not always ideal for equipment in basements, technical rooms, elevator shafts, industrial sites, or vehicles traveling through multiple countries.
With non-steered roaming, your device is not locked to a single preferred provider. The SIM can automatically connect to a suitable available mobile network at your location. This increases the likelihood of coverage and helps improve the continuity of your communication, especially when a local network is temporarily weak or unavailable.
According to its own coverage overviews, A1 Digital offers access to more than 400 roaming partners in over 180 countries. This makes the solution suitable for Dutch applications, European rollout, and international IoT projects where you want to work with a single SIM card.
Data, SMS, and voice on one SIM
These business IoT/M2M SIM cards support data, SMS, and voice.
The SIM works on GSM/2G, 3G, 4G/LTE, and 5G networks, depending on local availability and support from your modem or device. Additionally, A1 Digital supports LTE-M and NB-IoT for suitable IoT applications. Please note: voice depends on the network used, modem type, and selected SIM profile; NB-IoT, for example, is primarily intended for energy-efficient data communication and not for voice connections.

An IoT SIM for every device and every deployment
Choose a standard IoT SIM (UICC) with a single profile for simple and reliable connectivity, or choose an IoT eSIM (eUICC) for maximum flexibility and future-proofing. With an eSIM, you can remotely change the network profile whenever your coverage, application, or deployment requires it.
Whatever choice you make, IoT Discount helps you with the right SIM configuration, connectivity, and technical support for your IoT or M2M project.
Still not sure about the correct SIM form factor?
Have you already selected your devices? Then the required SIM form factor is usually already known. If you are starting from scratch, we are happy to help you choose the right version for your hardware and application.
IoT Discount IoT SIM cards are available as mini-SIM (2FF), micro-SIM (3FF), nano-SIM (4FF), and eSIM (eUICC). Combine the right form factor with local, European, or global connectivity and ensure your device is correctly connected from the start.
Integrated SIM (MFF2)
Do you want to integrate connectivity directly into your production process? The MFF2 embedded SIM is soldered directly onto the printed circuit board and is ideal for compact, rugged, and hard-to-reach IoT devices.
This fixed SIM solution saves space, prevents loose contact points, and offers extra protection against vibrations, moisture, and tampering. Ideal for sensors, trackers, industrial equipment, and other devices that need to remain reliably connected for extended periods.
Multi-format SIM card (2FF, 3FF and 4FF)
Do you want easy access to your devices after installation and a practical, affordable SIM solution? Then the classic multi-format IoT SIM card is an excellent choice.
Simply choose the right size — mini-SIM (2FF), micro-SIM (3FF), or nano-SIM (4FF) — pop it out of the card, insert it into your device, and connect. A reliable and simple solution for a wide range of IoT and M2M applications.
