Blank Programmable SIM & USIM Cards
The backbone of mobile communication lies in the Subscriber Identity Module (SIM). However, standard commercial SIMs are not always sufficient for testing, development, or specialized operator deployment. This is where writable programmable cards come in.
At HKCARD, we supply blank 4G VoLTE ISIM/USIM cards that offer full flexibility. Our cards allow developers and operators to program ICCID, IMSI, ADM, KI, OPC, OP, and even mileage data, ensuring total control over network authentication.
1. Comprehensive Network Compatibility
Our products are designed for universal compatibility. We supply cards that support:
- 4G LTE / LTE Advanced: High-speed data connectivity.
- VoLTE (Voice over LTE): Crystal clear voice calls over 4G networks.
- WCDMA & GSM: Ensuring backward compatibility with 3G and 2G networks.
- FDD & TDD: Supporting various frequency duplex modes used by global operators.
This makes our Writable Blank 4G VoLTE ISIM/USIM Card the perfect choice for devices operating across different network generations.
2. All Form Factors: 2FF, 3FF, and 4FF
Devices vary in size, and so do their SIM slots. HKCARD ensures you never face compatibility issues. Our 100pcs/lot writable programmable blank SIM USIM cards often come in versatile 3-in-1 packages, including:
- 2FF (Mini SIM): The standard for older industrial equipment and feature phones.
