Frequently Asked Questions (FAQ) 

Q1: What is a blank SIM card?
A: A blank SIM card is an unprovisioned SIM that contains no network-specific data. It acts as a blank slate, allowing users to program critical information like IMSI, Ki, and OPc using specialized SIM programming software and a SIM programmer.

Q2: How do I program a blank SIM card?
A: You can program a blank SIM card using a SIM Card Reader Writer and our provided software. The process involves writing data files containing the IMSI, Ki, OPc, and other parameters directly to the card’s memory. HKCARD provides a full SDK and guide.

Q3: Are your 5G SIM cards compatible with private networks?
A: Absolutely. Our Programmable 5G USIM and Private Network SIM Solutions are specifically designed for Private 5G deployments. They allow for full customization of network credentials, making them ideal for secure, enterprise-level networks.

Q4: Do you offer a Sysmocom alternative?
A: Yes. Our sysmoISIM-SJA5 Compatible 5G USIM Cards are a leading Sysmocom Alternative, offering the same functionality and reliability for private LTE/5G core network testing and deployment.

Q5: What is the difference between a dummy SIM card and a blank SIM card?
A: A dummy SIM card is a plastic placeholder with no chip or electronic function, used only to fill the SIM slot. A blank SIM card is a fully functional smart card that is ready to be programmed with network credentials.
