HKCARD ELECTRONICS CO.,LIMITED (HKCARD) supplies programmable blank LTE USIM cards for telecom operators, network testing, and IoT deployments. These 128K 4G SIM cards support FDD LTE, WCDMA, and GSM networks. The cards come blank and writable, allowing you to write your own ICCID, IMSI, KI, and OPC data.
Since the COS (Chip Operating System) is already installed, you do not need to program the COS. You only need to write the network profile data. A SIM tool is provided by HKCARD upon request to help you complete the writing process.

HKCARD provides the SIM tool on request for card reading and writing.
If you do not have a SIM programmer or prefer not to handle the data writing yourself, HKCARD can do it for you. As a professional SIM card provider, HKCARD accepts your SIM card data and writes all the information inside the card before shipping. You receive fully programmed, ready-to-use SIM cards.
