As the global transition toward standalone 5G (5G SA) and private LTE networks accelerates, the demand for reliable, customizable, and secure subscriber identity modules has never been higher. Whether you are building a native TDD-LTE network or deploying a 5G SA core using open-source solutions like Open5GS, the foundation of your network’s security and functionality lies in the SIM card.
HKCARD ELECTRONICS CO.,LIMITED provides industry-leading blank SIM cards and industrial-grade programming tools designed specifically for advanced network deployments.
1. Blank LTE/5G SIM Card Batches by HKCARD
When deploying a private network, off-the-shelf SIM cards rarely meet the specific architectural requirements of custom core networks. HKCARD offers high-quality blank SIM batches tailored for both LTE and 5G SA applications.
Our blank SIM cards are designed to support the latest 5G SA (Standalone) mode, ensuring ultra-low latency and full network slicing capabilities without relying on legacy LTE EPC cores.
2. Advanced Authentication: XOR & Milenage Algorithms
Network security is paramount, especially when operating a native TDD-LTE or 5G SA platform like Open5GS. To ensure seamless and secure authentication between the user equipment (UE) and the core network, HKCARD blank SIM cards fully support both XOR and Milenage authentication algorithms.
- Milenage Algorithm: The gold standard in telecommunications, providing robust security through a complex set of cryptographic functions.
- XOR Algorithm: A lightweight alternative often used in private and test networks, allowing for simplified authentication processes.
With HKCARD SIM cards, network engineers have the flexibility to choose the algorithm that best fits their security model and core network configuration.
3. Fully Customizable IMSI, KI, and OPC Codes
A critical requirement for deploying a 5G SA network on platforms like Open5GS is the ability to define and manage your own subscriber credentials. HKCARD blank SIM cards allow for complete customization of the following parameters:
- IMSI (International Mobile Subscriber Identity): Define your own network codes and subscriber identities.
- KI (Subscriber Authentication Key): Inject your own primary cryptographic keys to ensure absolute control over network access.
- OPC (Operator Code Variant): Customize the operator variant algorithm configuration for secure Milenage authentication.
This level of customization ensures that your private 5G SA network remains entirely autonomous, secure, and perfectly synced with your Open5GS or native TDD-LTE core network database.
4. Industrial USB SIM Card Reader/Writer & PC Software
Writing custom cryptographic keys and algorithm parameters onto blank SIM cards requires precision and reliable hardware. HKCARD provides a complete programming solution:
- 1x Industrial USB SIM Card Reader/Writer: Built for high-volume and repeated use, this industrial-grade reader ensures stable communication between the PC and the SIM card chip, preventing data corruption during the writing process.
- Dedicated PC Software: Our intuitive PC software allows engineers to easily input IMSI, KI, OPC, select between XOR or Milenage algorithms, and batch-write credentials to the blank SIM cards with just a few clicks.
