Programmable USIM Cards & Blank Writable SIM Cards: HKCARD Electronics
Introduction
HKCARD Electronics Co., Limited is your reliable partner in the mobile phone SIM cards industry. With over a decade of experience, we specialize in blank/writable SIM cards, programmable USIM cards, and complete SIM card programming solutions. Our products empower developers, operators, and testers to create and manage custom 4G/5G subscribers—fast.
What Are Programmable USIM Cards?
Programmable USIM cards (Universal Subscriber Identity Module) are blank, rewritable SIMs designed for full customization. They allow you to program essential parameters—IMSI, Ki, ICCID, OPC—for accessing and testing 4G LTE and 5G networks. Unlike standard operator-locked SIMs, our cards (similar to sysmoUSIM) enable:
- IMSI assignment for any network
- Ki key injection for authentication
- ICCID personalization for inventory control
