📶 Our Core Product Lines: Powering 4G, 5G & IMS Networks

1. Blank Programmable USIM Cards (128K & 256K)

Our Programmable USIM cards are ideal for R&D, lab testing, and custom provisioning. These blank SIMs support full personalization via industry-standard tools and are compatible with:

  • 3GPP-compliant networks
  • HSS/AAA servers
  • Diameter & SIP protocols

Used widely in 4G & 5G USIM Programmable SIM Cards for LTE Testing, these SIMs enable seamless authentication and ciphering in both standalone and non-standalone 5G deployments.


2. VoLTE ISIM & VoLTE SIM Cards – Optimized for IMS Services

What is a VoLTE SIM card?
A VoLTE SIM (Voice over LTE) enables high-definition voice calls over 4G/5G data networks using IP Multimedia Subsystem (IMS). For true IMS interoperability, our voLTE ISIM Cards include the ISIM (IP Multimedia Services Identity Module) application, which securely stores private user identities (IMPI) and authentication keys (IK/AK).

We offer:

  • VoLTE SIM Karte (German market)
  • 4G VoLTE Programm SIM Karte ISIM USIM Karte 128k
  • 4G VoLTE Programm SIM card ISIM USIM card 128k
  • Preloaded with Milenage Algorithm or XOR Algorithm SIM profiles

These are essential for:

  • VoLTE, ViLTE, and RCS service validation
  • IMS core testing
  • Interoperability between UE and IMS platforms

3. VoLTE Test SIM Cards for Network Validation

Our VoLTE Testing SIM Cards are pre-configured with IMSI, Ki, OPC, and ISIM data for immediate use in:

  • 4G 5G VoLTE Test SIM Cards scenarios
  • Handover testing (CSFB, SRVCC)
  • Emergency call simulation
  • Roaming and authentication stress tests

These Custom Programmable SIM Cards support dynamic profile loading and can be tailored for specific frequency bands, APNs, and carrier settings.


4. MIFARE®-Based Smart Cards – Secure & Durable

As a trusted MIFARE card supplier, HKCARD offers:

  • MIFARE Classic® 1K/4K
  • MIFARE DESFire® EV2/EV3
  • MIFARE Plus® SE
  • NFC Forum Type 1–4 compliant tags

Applications:

  • Access control
  • Public transportation
  • E-payment systems
  • Student ID & corporate badges

All cards are produced under strict quality control and support NDEF formatting, dynamic encryption, and anti-cloning features.


5. XOR & Milenage Algorithm SIM Cards – For Secure Authentication

Security is paramount in telecom networks. Our Milenage Algorithm SIM series uses the 3GPP-standardized f1–f5 functions with AES-128 encryption for mutual authentication between UE and AuC.

We also provide:

  • XOR Milenage Algorithm SIM – A lightweight alternative for legacy or constrained environments
  • XOR Algorithm SIM – Custom logic for private networks and closed-loop systems

These are widely used in:

  • Private 4G/5G networks
  • Military & government comms
  • Industrial IoT gateways

❓ Frequently Asked Questions (FAQ)

What is a VoLTE SIM card?

A VoLTE SIM card supports Voice over LTE services by enabling IMS registration. It must contain either a USIM or ISIM application to authenticate with the IMS core. Unlike traditional SIMs, VoLTE SIMs handle voice as data, delivering HD audio and faster call setup.

Are your VoLTE SIM cards prepaid?

Yes, we offer VoLTE SIM cards prepaid options for trial deployments, demos, and temporary use. Custom billing models and postpaid configurations are also available upon request.

Can I customize the SIM with my brand logo?

Absolutely! We provide OEM/ODM services including:

  • Custom ICCID ranges
  • Branded packaging
  • Laser engraving
  • Preloaded APN & PRL settings

🌍 Global Reach, Local Support

Headquartered in Hong Kong with production facilities in mainland China and technical partners across Southeast Asia and Europe, HKCARD Electronics ensures fast delivery and responsive customer service. We comply with:

  • ISO/IEC 7816 (Smart Card Standards)
  • ETSI TS 102 221 (UICC)
  • 3GPP TS 33.102 (Security Architecture)

Our SIMs are used by Tier-1 operators, Huawei-certified labs, and leading universities conducting 5G research.
