 HKCARD SUCI SIM Card & Programmable 5G SIM for German Private Campus Networks

Germany’s Industrie 4.0 and Private 5G Campus Networks (Campusnetze) demand a new breed of SIM technology—one that goes far beyond the rigid, pre-programmed cards offered by traditional MNOs. HKCARD ELECTRONICS CO.,LIMITED, a leading OEM SIM Supplier with over 10 years of experience, delivers the solution: SUCI SIM cards, programmable sim card 5g technology, and blank sim cards fully compatible with the European Open Source ecosystem.

Whether you’re deploying a Private 5G testbed, validating 5G Standalone (SA) security protocols, or integrating with Osmocom, pySim, or sysmocom sim card workflows, HKCARD provides the hardware and software tools you need.

 What is a SUCI SIM Card? Understanding 5G Privacy & Security

A SUCI SIM card is a next-generation programmable sim card 5g that supports Subscription Concealed Identifier (SUCI) generation—a cornerstone of 5G security architecture. Unlike legacy 4G networks where the subscriber’s permanent identifier (IMSI) is transmitted in clear text during authentication, 5G uses SUCI to encrypt the Subscription Permanent Identifier (SUPI) using the home network’s public key.

Key Technical Benefits of HKCARD’s SUCI SIM:

  • Privacy Protection: Prevents IMSI-catchers and rogue base stations from harvesting subscriber identities.
  • 5G SA Compliance: Essential for 5G Standalone (SA) architecture.
  • Customizable Security Schemes: Full control over protection profiles (Profile A, Profile B) and home network public keys.

HKCARD’s suci sim cards provide full write access to the SUCI_CALC_INFO Elementary File, enabling researchers and network architects to test different encryption schemes, key rotations, and routing indicators.

 Programmable 5G SIM Cards: Full Control Over 5G Parameters

Standard MNO SIMs are locked. HKCARD’s programmable sim card 5g portfolio breaks that barrier, offering Writable Programmable SIM technology that puts you in control.

 Critical 5G Elementary Files You Can Program

5G Parameter (EF)Function & Use CaseHKCARD Writable?
SUCI_CALC_INFOStores home network public key, protection scheme, and routing indicator. Essential for testing SUPI concealment and validating UDM/AUSF functions.✅ Fully Writable
UAC_AICUnified Access Control and Access Identity Control. Configure access categories for network slicing, priority access, and load testing.✅ Fully Writable
SUPI_NAIDefines the SUPI in Network Access Identifier format. Critical for non-3GPP access (Wi-Fi) and roaming scenarios.✅ Fully Writable
5GS3GPPLOCILast registered 5GS location for 3GPP access. Simulate mobility events without physical movement.✅ Fully Writable
5GSN3GPPLOCILast registered 5GS location for non-3GPP access. Test access network selection and handover policies.✅ Fully Writable

This level of access transforms a blank sim card into a powerful testing and validation tool for 5G core networks, security research, and German Campusnetz deployments.

Empty SIM Cards & Blank SIM Cards: The Foundation for Custom Solutions

HKCARD supplies empty sim cards and blank sim cards that are ready for personalization. These are not consumer-grade products—they are industrial-grade Writable Programmable SIM cards designed for professional use.

What makes HKCARD’s blank SIM cards different?

  • JavaCard OS with Extended Memory: Support for SIM JAVA 128K for custom applet deployment.
  • Full EF Write Access: Unlike consumer SIMs, all Elementary Files are unlocked and accessible.
  • Pre-loaded with 5G/4G File Structure: Saves setup time; the file system is already ISO 7816 and 3GPP TS 31.102 compliant.
  • Compatible with sysmocom sim card workflows: Drop-in replacements for sysmoUSIM-SJS1 and similar products.

Open Source SIM Ecosystem: pySim, Osmocom & sysmocom Compatibility

European engineers and researchers rely on Open Source tools. HKCARD’s Open Source SIM cards are validated for seamless integration with the most popular platforms:

HKCARD Open Source SIM cards compatible with:

  • Osmocom: Full support for the Osmocom cellular infrastructure stack. Our SIMs work perfectly with osmo-hlr, osmo-msc, and Open5GS.
  • pySim / pySim-prog: Direct Python scripting support. Read/write all EFs including SUCI_CALC_INFO, UAC_AIC, and SUPI_NAI with simple commands.
  • sysmoUSIM / sysmocom sim card: HKCARD SIMs are designed as high-performance, cost-effective alternatives to sysmocom products, with identical or superior programmability.

Example pySim Command:

Bash

 

./pySim-prog.py -p 0 -t sysmoUSIM-SJS1 -a 12345678 \
  --imsi=901700000012345 --ki=00112233445566778899AABBCCDDEEFF \
  --opc=63BFA50EE6523365FF14C1F45F88737D \

SIM Personalize Tools & SIM Programming Software for Batch Operations

For Private 5G deployments requiring hundreds or thousands of SIMs, manual programming is not scalable. HKCARD provides professional SIM Personalize Tools and SIM Programming Software designed for high-volume operations.

Key Features:

  • Batch Template Processing: Create one master profile with all 5G parameters (IMSI, Ki, OPc, SUCI keys, UAC settings) and replicate it across thousands of cards.
  • Multi-Slot SIM Card Programmer Support: Program up to 25 SIMs simultaneously with our industrial SIM Card Programmer hardware.
  • GUI & CLI Modes: Use the graphical interface for setup or script the CLI for DevOps integration.
  • Audit & Traceability: Every personalization event is logged with cryptographic hashes for security compliance.

This is essential for German Campusnetz integrators who need to provision secure, custom SIMs for enterprise clients quickly and reliably.
