HKCARD ELECTRONICS CO.,LIMITED (HKCARD) supplies a programmable blank SIM card for operators, test labs, and device makers who need to write their own subscriber data. The card is a USIM/ISIM type and supports 2G, 3G, and 4G. It comes in a 3-in-1 body with Mini, Micro, and Nano sizes. HKCARD also offers this card in a dual-module version, which puts two independent SIM modules on one card body.
1. Card Type, Network Support, and Form Factor
This HKCARD blank SIM card is designed for projects that need full control over SIM parameters.
- Type: Programmable SIM card (USIM / ISIM)
- Condition: Blank, ready for later personalized writing
- Supported cellular standards: GSM (2G), WCDMA / UMTS (3G), LTE / 4G
- Form factor: 3-in-1 — 2FF (Mini-SIM), 3FF (Micro-SIM), 4FF (Nano-SIM)
- Color: White, gray, or other colors on request
The 3-in-1 design means you do not need to stock three separate card sizes. Snap out the size you need for each device.
2. Dual-Module or Single-Module Execution
HKCARD offers two physical card layouts:
- Dual-module: Two independent SIM modules on a single card. You get two usable SIM cards from one card body. This is useful for dual-SIM devices, paired test profiles, or production runs where you want to reduce card body waste.
- Single-module: One SIM module per card. Standard option for most single-SIM devices.
Both versions carry the same blank USIM chip and the same write capabilities. The choice depends on how you manage cards in the field or in the lab.
3. Writable Parameters and Programming Support
This is a blank card for personalization. You can write the following parameters with a standard SIM personalization tool:
- IMSI: Subscriber identity
- KI: Authentication key
- OPC: Operator code for MILENAGE / COMP128 authentication
- ACC: Access Control Class, including Class 15
- PIN / PUK: Access protection codes
Programming is compatible with standard SIM personalization tools. If you do not have a programmer, HKCARD can write your data before shipping. You provide the IMSI, KI, OPC, and other values, and HKCARD delivers ready-to-use cards.
4. Memory, Security, and Durability
The HKCARD programmable blank SIM card is built for long-term use in different environments.
- Memory type: EEPROM
- Access protection: PIN / PUK
