OEM SIM Supplier for German Private 5G Campus Networks: HKCARD Open Source SIM Solutions

As Private 5G campus networks rapidly expand across Germany and Europe, enterprises, system integrators, and research institutions require highly customizable and secure SIM solutions.

HKCARD ELECTRONICS CO., LIMITED is a trusted OEM SIM Supplier delivering advanced SIM Card Manufacturing and SIM Personalization services tailored specifically for European Private 5G deployments.

From industrial campuses in Germany to research labs across the EU, HKCARD provides Open Source SIM cards compatible with Osmocom, pySim, and sysmoUSIM, enabling flexible, standards-compliant, and scalable network implementations.

Private 5G in Germany: Why SIM Customization Matters

Germany is leading Europe in Industry 4.0 and private 5G campus networks, with deployments in:

• Smart factories
• Automotive production plants
• Logistics hubs
• Research universities
• Energy and utility infrastructure

Unlike public mobile networks, these private environments require deep SIM-level customization, including support for advanced 5G parameters such as:

• 5GS3GPPLOCI (5G location information storage)
• 5GSN3GPPLOCI
• SUCI_CALC_INFO (Subscription Concealed Identifier calculation)
• UAC_AIC (Access control parameters)
• SUPI_NAI (Network Access Identifier format for SUPI)

HKCARD SIM solutions are designed to support these parameters through flexible personalization and programming workflows.

HKCARD Open Source SIM for European Private 5G Networks

HKCARD specializes in Open Source SIM solutions that integrate seamlessly with the most widely used European telecom stacks.

Compatible Platforms:

• Osmocom
• sysmoUSIM-style environments
• pySim / pySim-prog
• sim-tools
• Open5GS / srsRAN / Free5GC ecosystems

These platforms are commonly used in Germany and across Europe for:

• Private 5G network deployment
• Lab testing and validation
• Security research
• Telecom prototyping

HKCARD SIMs provide a reliable hardware foundation for these open environments.

Advanced 5G SIM Data Support

One of the key requirements for German private 5G networks is support for modern 5G identity and security structures.

HKCARD supports:

• SUPI (Subscription Permanent Identifier)
• SUPI_NAI format for enterprise identity mapping
• SUCI (Subscription Concealed Identifier)
• SUCI_CALC_INFO for privacy-preserving authentication
• 5GS3GPPLOCI / 5GSN3GPPLOCI for mobility and registration
• UAC_AIC for access control and network slicing policies

These parameters are configured through professional SIM Personalization workflows, ensuring compatibility with 5G Core (5GC) implementations used in Europe.

Writable Programmable SIM for Private 5G and R&D

For German enterprises and research labs, flexibility is critical. HKCARD offers Writable Programmable SIM solutions that allow controlled modification of key parameters.

Supported Writable Features:

• Writable IMSI SIM Cards
• Writable Ki SIM Cards
• Writable OP or OPc SIM Cards
• Writable SPN, MCC, MNC
• Writable SUPI / SUCI configurations

These SIMs are ideal for:

• Private 5G testing
• Network simulation
• Multi-tenant campus networks
• Device certification
• Security validation

Writable SIMs reduce development time and allow engineers to adapt quickly to changing network configurations.

SIM Personalize Tools for Batch Operations

Large-scale campus deployments in Germany often require thousands of SIM cards configured consistently. HKCARD provides SIM Personalize Tools for batch operations to support:

• Bulk IMSI and ICCID injection
• Ki / OPc secure personalization
• 5G parameter configuration (SUCI, SUPI, LOCI)
• Operator profile setup
• Automated batch verification

These tools ensure:

• High efficiency
• Reduced human error
• Consistent SIM performance
• Scalable deployment
