HKCARD ELECTRONICS CO.,LIMITED (HKCARD) supplies blank SIM cards, programmable SIM cards, test SIM cards, and multinetwork 4G VoLTE SIM cards for labs, IoT teams, and production lines. This page explains the main card types, how they work with a SIM programmer, and how to order from HKCARD.
1. SIM Programmer Basics: What It Does and What It Works With
A SIM programmer is a tool used to read, write, or edit data on a SIM card. With it, you can set ICCID, IMSI, Ki, SPN, and other network files. Test engineers use SIM programmers to:
- Program a blank SIM card for private GSM or LTE test networks
- Create test SIM cards for phone, router, and module QA
- Prepare programmable SIM cards for field trials
- Write multi-network profiles for 4G VoLTE devices
HKCARD cards are standard ISO 7816 SIM cards. They work with common SIM programmer hardware and with many sysmocom-based tools used in open-source telecom projects. If you already have a programmer, HKCARD can help you match the right chip type.
2. HKCARD Blank SIM Cards: White, Triple Format, and Ready to Program
A blank SIM card from HKCARD comes unprogrammed. You write the profile yourself with a SIM programmer. HKCARD offers several formats:
- Blank white triple format SIM: one white card body with 2FF (mini), 3FF (micro), and 4FF (nano) cutouts. You snap out the size you need, which keeps one SKU in stock.
- Single-format blank SIM cards: choose 2FF, 3FF, or 4FF only if your device has a fixed slot.
- Programmable SIM cards: chips that accept custom profiles. Some models can be rewritten multiple times.
Why teams choose HKCARD blank SIM cards:
- White surface works well for barcode or logo printing
- Triple format reduces the number of SKUs you need
- Cards hold data after programming
- Small sample packs and bulk orders are available
3. sysmocom and Programmable SIM Cards: A Practical HKCARD Option
sysmocom is a common name in open-source mobile telecom. Many developers use sysmocom tools or follow sysmocom-style setups for GSM, LTE, and SIM card testing. HKCARD supplies its own programmable SIM cards that fit the same workflows.
If your project uses pySIM, SIMtrace, or a similar sysmocom-style toolchain, ask HKCARD for a card sample. HKCARD can tell you:
- The chip type and file system
- Whether the card supports your programmer
- Whether the card can be reprogrammed
- Which ADM keys or access conditions apply
This is helpful when you need blank SIM cards for testing but want a steady supply without ordering large lots.
4. Multinetwork 4G VoLTE SIM Cards and Test SIM Cards
HKCARD also supplies multinetwork 4G VoLTE SIM cards for devices that need LTE data and voice. These cards are commonly used in:
- 4G routers and CPEs
- IoT gateways and trackers
- Smart meters and industrial modules
- Lab benches that test network switching
The multinetwork 4G VoLTE SIM card can be provisioned for different operator profiles, depending on your requirements. A test SIM card from HKCARD gives you a stable, known profile for comparing device behavior during QA. This is easier than using consumer SIM cards that may change settings or lock you to one network.
5. How to Order HKCARD SIM Cards and Get Support
Contact HKCARD ELECTRONICS CO.,LIMITED for samples, datasheets, or pricing. When you write in, include:
- SIM card size: 2FF, 3FF, 4FF, or blank white triple format

HKCARD supports small test orders and full production runs. If you are not sure which blank SIM card or programmable SIM card fits your project, send a short message and HKCARD will recommend one.
Quick answers before you order:
- HKCARD blank triple format SIM cards can be programmed with standard SIM programmers.
- HKCARD supplies its own programmable SIM cards, not sysmocom-brand cards. They are a practical option for sysmocom-style workflows.
- Test SIM cards and multinetwork 4G VoLTE SIM cards are available for IoT and device testing.
