Applications Across Industries

  • Mobile Network Operators (MNOs): Testing VoLTE roaming, 5G SA rollouts, and SRVCC handovers.
  • Device & Chipset OEMs: Validating “Sim card and VoLTE” functionality, modem firmware, and SAR.
  • Certification Labs: Running GCF, PTCRB, GSMA test cases (e.g., TS.11, TS.12).
  • IoT & M2M Developers: Securing 4G Cat-M, NB-IoT with XOR Algorithm SIMs.
  • Universities & Academia: Teaching network security with Milenage SIMs.

FAQ: Your Questions Answered

Q: What is a VoLTE SIM card?
A: A VoLTE SIM card is a USIM with an ISIM application that enables HD-voice calls over 4G/5G data networks, eliminating the need for 2G/3G circuit-switched voice.

Q: Why do I need programmable SIMs for VoLTE testing?
A: Blank programmable USIM cards allow you to write custom Ki, OPC, IMSI, and PLMN values to simulate any carrier, test roaming, or validate device behavior.

Q: Can I program my own security keys?
A: Yes. HKCARD’s programmable USIM cards support APDU commands for full control over Ki, OP, OPC, AMF, and SQN.

Q: What’s the difference between Milenage and XOR algorithms?
A: Milenage is 3GPP’s standard algorithm for authentication. XOR is lightweight for IoT devices with limited processing power.

Q: What’s the minimum order quantity?
A: Stock SIMs: 10 pcs. Custom SIMs: 100 pcs (with your logo, profiles, packaging).
