HKCARD programmable 4G LTE SIM card — rewritable blank SIM for telecom testing and development. Write IMSI, Ki, ICCID, OPC. Fast shipping to Lebanon, Chile, Brazil & South America
HKCARD ELECTRONICS CO., LIMITED supplies a programmable SIM card 4G LTE — a rewritable blank SIM card built for custom telecom testing, SIM development, and mobile network engineering. Each card ships with a pre-installed card operating system (COS) and a rewritable EEPROM, so you can write IMSI, Ki, ICCID, and OPC values using a standard SIM card reader and programming software. The card runs on 2G GSM, 3G UMTS, and 4G LTE networks, and HKCARD delivers worldwide — including fast, secure shipping to Lebanon, Chile, Brazil, and across South America.
What Is a Programmable Blank SIM Card?
A programmable blank SIM card is a smart card that arrives with no subscriber data on it. Instead of a fixed carrier profile, the card carries an empty, rewritable memory area that you load yourself — IMSI, Ki, ICCID, OPC, and other data fields — using a USB SIM card reader and SIM programming software.
This gives engineers full control. A retail SIM card from a carrier comes pre-loaded and locked. A blank writable SIM from HKCARD lets you change the profile as often as your project requires: write one configuration for a GSM test, rewrite it for UMTS, then write an LTE profile for 4G testing. Because 4G behavior depends on carrier support and the configuration you write, the card works best for controlled testing, lab work, and development environments.
Key Features of the HKCARD Programmable SIM Card 4G LTE
- Fully writable: Configure IMSI, Ki, ICCID, OPC, and other data fields with common SIM card programming tools and reader software.
- Multi-network compatibility: Operates on GSM (2G), UMTS (3G), and 4G LTE networks, depending on carrier support and your written configuration.
- High rewrite durability: Supports over 100,000 write cycles with more than 10 years of data retention — enough for long-term test benches and repeated profile changes.
- 3-in-1 SIM format: Full-size card with breakable cuts for mini (2FF), micro (3FF), and nano (4FF) sizes. One card fits any device slot.
- Developer-friendly: Suited to mobile R&D, IoT prototyping, M2M communication, and SIM Toolkit (STK) development.
Technical Specifications
| Item | Detail |
|---|---|
| Card operating system | Pre-installed COS |
| Supported networks | GSM (2G), UMTS (3G), LTE (4G) |
| SIM format | 3-in-1 (Standard / Micro / Nano) |
| Write cycles | >100,000 |
| Data retention | >10 years |
| Internal data RAM | 256 bytes |
| External data XRAM | 2,048 bytes |
| Flash memory | 80K bytes (COS area + user data area) |
| CPU core | High-performance 8-bit HC8051 |
The 80K-byte flash is split between the card operating system and user data, while the 8-bit HC8051 core handles authentication and file operations quickly enough for live network testing.
Applications – Who Uses Programmable SIM Cards?
- Telecom network testing: Verify registration, attach behavior, and handover on live 2G/3G/4G networks without waiting for carrier-issued test cards.
- SIM and STK development: Build and debug SIM Toolkit applications before deployment.
- IoT and M2M prototyping: Test SIM modules in trackers, sensors, and industrial devices that switch between network types.
- Lab and research use: Universities and R&D teams use blank writable SIMs to study SIM architecture, authentication logic, and card file systems.
- Regional carrier work: Engineers in Lebanon, Chile, Brazil, and wider South America rewrite card profiles to match local networks and test requirements.
FAQ – Programmable SIM Cards from HKCARD
Q1: Does this card support 4G LTE?
Yes. The card works on LTE networks when the written profile and carrier settings support it. Actual 4G performance always depends on the local carrier and your configuration.
Q2: What do I need to program the card?
A PC/SC-compatible USB smart card reader and SIM programming software. The HKCARD team can guide you through the setup.
Q3: How many times can I rewrite the card?
Over 100,000 write cycles, with data retention of more than 10 years.
Q4: Which SIM sizes are included?
One 3-in-1 card covers standard, micro, and nano formats — simply break away the size you need.
Q5: Do you ship to Lebanon, Chile, Brazil, and South America?
Yes. HKCARD ships worldwide with fast, secure delivery to Beirut, Santiago, São Paulo, and every country in the region.
Q6: Are samples available?
Yes. Contact HKCARD ELECTRONICS CO., LIMITED directly for samples, pricing, and bulk orders.
