Sm@rtSIM® – Our comprehensive secure SIM and eUICC Portfolio
SIM cards started as basic authentication tools for mobile communication. Today, they have evolved into more than that; multifunctional secure devices. As a global SIM card manufacturer, we deliver solutions that provide reliable authentication, protect sensitive data, and support digital services such as payments, transit, automotive access, and IoT applications. From classic SIM to eSIM and iSIM, our portfolio ensures long-term adaptability and trusted connectivity.
Since we delivered the world's first commercial SIM card to a telecommunications company in Finland in 1991, our company has been – and continues to be – a major force in defining international SIM standards.
At G+D, we proudly say we were part of the invention of the SIM. We have been involved in every step of its development: from the evolution of network technology (early GSM to 5G), to size reduction (from credit card-sized to SMD), and the introduction of fundamental technologies like eSIM management. We've always provided the right solution for any business model – helping you best serve your customers.
Our Sm@rtSIM® portfolio is the trusted foundation for secure mobile network authentication and SIM applications worldwide. Whether in smartphones, IoT devices, or connected vehicles, Sm@rtSIM® enables robust, flexible, and future-ready connectivity across all types of networks – public, private, and even satellite-based.
Key benefits of SIM Cards
Protect sensitive identities and data with strong encryption and globally recognized security standards.
They are THE key enabler of global mobile connectivity, acting as a portable identity module that allows users to access mobile networks anywhere in the world. The SIM comes in many form factors – pluggable SIM, eSIM, and iSIM – with flexible remote management for reliable global connectivity across devices and networks.
Adapt to evolving requirements with lifecycle management, remote updates, and technologies ready for tomorrow’s networks.
Smart SIM Cards: Fields of Application
G+D provides a full range of SIM variants tailored for consumer, industrial/M2M, and automotive use cases.
Consumer SIM cards
Our Sm@rtSIM® product families meet all mobile network operator requirements, covering all network technologies and generations. These Java-based cards are modular and available in a wide range, from basic to high-end – including the latest 5G SIM cards. They enable mobile operators to expand their service offerings to banks, public transit authorities, and other service providers.
IoT SIM Cards
- Apart from the ubiquitous smartphone, an increasing number of devices – including sensors, meters, fleet containers and agriculture monitors - are now connected and exchange information.
- SIM cards play a crucial role in the IoT landscape. Industrial IoT SIMs, also known as M2M SIM cards must meet specific requirements, such as extended temperature ranges (up to 105°C), longer lifespans, and more erase/write cycles.
- These dedicated SIM cards for IoT not only protect network access for MNOs but also safeguard IoT data and support and help tackle the far-reaching concerns of IoT device lifecycle management.
- For Low Power Wide Area Network (LPWAN) and Cellular NB-IoT networks, we offer SIMs which support the low power requirements of these networks.
Automotive SIM Cards
- Automotive SIMs must comply with several industry-specific requirements, such as higher temperature range up to 125°C, longer lifetime and more erase/write cycles.
- They must also comply with specific requirements for Quality Assurance, including IATF 16949.
- Secure, trusted connectivity is critical to the success of the connected vehicle ecosystem. The Automotive SIM typically enables the automated emergency call function. Our products are certified for eCALL and support a wide range of data services for both OEMs and drivers.
Features of our secure SIM Cards
Sm@rtSIM®, our smart SIM Card portfolio family, comes in various variants depending on your use case. It supports multiple form factors, features, applications, eSIM management, and even remote OS updates.
SIM Form Factors
SIM cards are available in several form factors, each designed for specific requirements. The following table gives an overview of the main options and their characteristics.

eSIM Management
Depending on the deployment model, Sm@rtSIM® can be delivered with a fixed subscription or enabled for Remote SIM Provisioning.
eSIM enabled SIMs, also called eUICC (embedded Universal Integrated Circuit Card), allow mobile subscriptions to be managed over-the-air to update or switch network providers remotely.
Remote SIM Provisioning is especially relevant for embedded form factors and follows GSMA specifications to ensure global interoperability.
SIM OS Update
The eUICC Operating System (eUICC OS) is the embedded software that governs the core functionality and security of an eUICC. Updating or modifying the OS typically requires a specific update mechanism.
With G+D OS Update (also known as ITL – Image Trusted Loader) we enable seamless deployment of bug fixes and security enhancements - without physical replacement, ensuring long-term adaptability and future readiness.
SIM Applications
We offer a huge variety of SIM applications supporting many use cases:
- Multi IMSI
- IMEI Lock
- Zero Touch Provisioning
- Life Time Monitoring
- QoS
- Payment Applications (compliant to EMVCo, American Express, Mastercard and Visa)
- Transit (MIFARE®, CIPURSE™, and Calypso)
- Roaming
- IoT Safe
- … and many more
Converged solutions: SIM and security element on one chip
The converged solution integrates SIM and multiple security applications on a single chip, e.g. for mobile connectivity, mobile payment and transit.
It combines two separate components, the eUICC and the eSE (embedded Secure Element) on a single chip and meets all relevant specifications and certification requirements of the GSMA as well as international payment and transit organizations.
Sustainable SIM cards
Growing environmental awareness and enterprise responsibility are driving demand for eco-friendly products and sustainable SIM card solutions.

Quantum-Safe SIM Cards – SIM Security for the future
SIMs are using cryptographic algorithms such as RSA and ECC (Elliptic Curve Cryptography) that are too complex or time-consuming for traditional computers to break. However, a new era of quantum computers is on the horizon, promising significantly greater power. Experts estimate that such quantum computers might be available in the 2030s.
To protect SIMs from this looming threat, a new type of cryptography is essential: post-quantum cryptography (PQC). PQC utilizes advanced algorithms capable of resisting even quantum-powered cyber-attacks, ensuring enduring cybersecurity.
Leading the charge in safeguarding critical data, we have been dedicated to creating quantum-resistant solutions for our SIM and eSIM solutions. We eagerly anticipate future technological advancements that will equip the industry for the challenges of tomorrow
