HKCARD ELECTRONICS CO.,LIMITED (HKCARD) provides high-quality programmable blank LTE USIM 4G cards designed for telecom operators, network engineers, and IoT developers. These cards are fully compatible with 4G FDD LTE, WCDMA, and GSM networks, offering a flexible solution for network testing and device provisioning.
One of the key advantages of the HKCARD programmable SIM is that the COS (Chip Operating System) is already installed. This means you don’t need to waste time programming the operating system; you can jump straight to writing your specific network data.
1. Technical Specifications of HKCARD Blank USIM Cards
For those requiring precise technical details for their hardware integration, HKCARD provides cards with the following specifications:
- Product Name: LTE Blank USIM Card
- Network Mode: 4G LTE / WCDMA / GSM
- Capacity: 128K
- SIM Slots: 2FF, 3FF, 4FF
- Compatibility: 4G FDD LTE and legacy 2G/3G networks
- Writable Fields: ICCID, IMSI, KI, OPC, PUK, PIN, and ADM
- Application: Telecom operators, lab testing, and industrial IoT
2. 3-in-1 Flexible Design: Mini, Micro, and Nano
To simplify inventory and ensure compatibility across all devices, HKCARD offers these cards in a 3-in-1 triple format. Instead of buying three different types of cards, you get one card that can be snapped into three different sizes:
- Standard SIM (Mini): Ideal for older industrial modems and legacy hardware.
- Micro SIM: Perfect for mid-range 4G modules and routers.
- Nano SIM: Designed for modern smartphones and compact IoT sensors.
This design ensures that whether you are testing a handheld device or a large network gateway, the HKCARD USIM will fit perfectly.
3. Fully Writable Data for Custom Network Profiles
The HKCARD programmable blank card gives you complete control over the subscriber identity and authentication keys. You can use a SIM programmer to write the following essential data:
- ICCID: The unique serial number of the SIM.
- IMSI: The international mobile subscriber identity used to identify users on the network.
- KI & OPC: The authentication keys required for the SIM to connect to the HLR/HSS.
- Security Codes: Ability to set and change PIN and PUK codes, as well as ADM administrative keys.
If you need a specific tool for this process, HKCARD provides the necessary SIM tools upon request to ensure a smooth writing process.
4. Professional Programming Services by HKCARD
Depending on your project needs, HKCARD ELECTRONICS CO.,LIMITED offers two flexible delivery options:
Option A: Blank SIM Cards
We ship the cards with the COS pre-installed. You receive the blank cards and use your own programmer to write the data internally.
Option B: Full Programming Service
If you do not have the hardware or prefer a turn-key solution, HKCARD can handle the programming for you. Simply provide us with your data (ICCID, IMSI, KI, etc.), and we will write all the information into the cards before shipping. You will receive ready-to-use SIM cards that are immediately compatible with your network.
