As the telecommunications landscape rapidly shifts towards 5G, massive IoT, and software-defined connectivity, the need for flexible, programmable SIM and USIM cards has never been greater. HKCARD ELECTRONICS CO.,LIMITED (HKCARD) stands at the forefront of this evolution, supplying a complete range of programmable SIM/USIM cards, test SIM solutions, eSIM chips, and industrial-grade SIM programming tools to customers worldwide. Whether you are a mobile network operator, a device manufacturer, an IoT solution provider, or a testing laboratory, HKCARD offers reliable, standards-compliant products designed to accelerate your development, simplify your testing, and scale your deployments.
Below you will find a detailed breakdown of HKCARD’s core programmable SIM card and programmer offerings, organized for easy scanning and deep understanding.
Cutting-Edge 5G SA/NSA Programmable USIM Cards (3GPP R16) and Blank 4G LTE SIMs
To meet the demands of modern mobile networks, HKCARD ELECTRONICS CO.,LIMITED provides programmable SIM and USIM products that cover the full spectrum from legacy LTE to the latest 5G architectures, all in a variety of plug-in form factors.
5G SA/NSA Programmable USIM (3GPP Release 16)
HKCARD’s flagship programmable USIM cards are fully compliant with 3GPP Release 16 specifications, making them ideal for both 5G Standalone (SA) and Non-Standalone (NSA) network environments. These cards can be personalized with custom operator profiles, authentication keys (such as 5G-AKA and EAP-AKA’), and operator-specific parameters, giving engineers and researchers total control over their test and deployment scenarios.
Key application areas include:
- 5G smartphone and CPE (Customer Premises Equipment) prototyping
- gNodeB and core network interoperability testing
- Network slicing and 5G SA feature validation
- Private 5G campus network rollout
- Industrial IoT sensor and gateway activation
- University and R&D lab communication modules
Because these are truly programmable, HKCARD’s 5G USIM cards support repeated re-personalization cycles (within file system limits), allowing for iterative testing without the need to purchase dozens of fixed-profile commercial SIMs.
4G LTE Blank / Writable SIM Cards (2FF/3FF/4FF)
For projects that rely on mature 4G infrastructure or require a multi-generation fallback, HKCARD supplies blank and writable LTE SIM cards. These cards are available in all three traditional plug-in form factors: Standard (2FF), Micro (3FF), and Nano (4FF). Customers can write their own IMSI, Ki, OPC, ADM keys, and file system structures using HKCARD’s programming tools or third-party pySim/PC/SC software.
Typical use cases:
- M2M communications in smart metering and logistics
- Embedding into GPS trackers, tablets, and rugged handhelds
- Customizing network lock/unlock parameters
- Low-volume operator provisioning and field trials
- Education and professional training labs
By offering blank LTE SIMs, HKCARD ELECTRONICS CO.,LIMITED empowers developers to take full ownership of their cellular connectivity, enabling rapid prototyping and reduced time-to-market.
Specialized Test SIM Cards for VoLTE, Multi-IMSI, SUCI, and IoT Deployments
Testing modern voice services, roaming scenarios, and secure IoT authentication requires SIMs that go far beyond basic network access. HKCARD understands this complexity and delivers a dedicated suite of advanced test SIM and programmable chip solutions.
VoLTE SIM Test Cards and Multi-IMSI Test SIM
HKCARD’s VoLTE test SIM cards are engineered to validate IMS (IP Multimedia Subsystem) voice services over LTE and 5G NR. They come pre-configured or programmable with the necessary ISIM and USIM applications to support HD Voice, Video over LTE (ViLTE), and emergency calling tests.
The Multi-IMSI Test SIM takes flexibility to the next level. By storing multiple International Mobile Subscriber Identities on a single card, network engineers can seamlessly switch between different operator profiles to simulate roaming conditions, load-balancing scenarios, and multi-operator device certification—all without physically swapping cards. This is an invaluable tool for:
- Device OEM validation labs
- Inter-operator roaming hub testing
- Smartphone certification and GCF/PTCRB pre-testing
- IMS core network optimization
SUCI, 5G IoT SIM, and eSIM Blank Chips
As 5G introduces Subscription Concealed Identifiers (SUCI) for enhanced privacy, HKCARD ELECTRONICS CO.,LIMITED provides programmable SIM solutions that support ECIES-based concealment, enabling secure network attachment without exposing the SUPI (Subscription Permanent Identifier). These programmable cards are perfect for IoT applications where identity protection is mandatory.
Further expanding the IoT portfolio, HKCARD offers:
- 5G IoT SIM cards optimized for low-power, wide-area applications (e.g., NB-IoT, LTE-M) with extended temperature ranges and durable packaging.
- Blank eSIM chips (eUICC-enabled, MFF2 form factor) ready for custom profile loading, supporting GSMA SGP.02 (M2M) and SGP.22 (Consumer) architectures.
Whether your business involves smart cities, connected cars, agricultural sensors, or wearable health devices, HKCARD has the programmable eSIM and IoT SIM building blocks you need to succeed.
Professional USB SIM Card Readers and Programmers for Desktop Personalization
Programming programmable SIM cards requires reliable, high-compatibility hardware. HKCARD ELECTRONICS CO.,LIMITED designs and supplies robust USB SIM card readers/programmers that form the bridge between your PC and the secure element.
These USB devices support standard PC/SC interfaces, making them plug-and-play compatible with Windows, Linux, and macOS environments. They work seamlessly with HKCARD’s own software as well as popular open-source tools like pySim, SIMsalabim, and vendor-specific utilities. Key features include:
- Support for all standard card formats (2FF/3FF/4FF) via adapters
- High-speed APDU communication for fast data transfer
- Durable, gold-plated contact pins for extended lifecycle
- Firmware upgradability to support evolving UICC commands
- Ideal for both single-card development and multi-card production lines
HKCARD’s USB SIM programmers are trusted in engineering benches, factory floors, and carrier labs around the world because of their proven stability and low command failure rates. For customers who need to program cards in a desktop environment day in and day out, this hardware provides a rock-solid foundation.
SIM Personalization Software and High-Volume Bulk Provisioning Kits
Hardware is only half the picture; powerful software and efficient provisioning flows turn blank programmable SIMs into fully functional identity modules. HKCARD provides a comprehensive toolchain for both R&D personalization and mass production.
SIM Personalization Software (pySim, PC/SC, and Custom Tools)
HKCARD’s software ecosystem is built around openness and compatibility. The company provides utilities, scripts, and graphical applications that support:
- Full ADM access for card administration
- Transparent and secure channel file system read/write
- Authentication parameter injection (Ki, OPC, SQN, etc.)
