 HKCARD Electronics – Your Trusted Supplier of Programmable SIM Cards for 4G, 5G & IoT Applications

Intro
With more than 15 years of experience in the mobile phone SIM card industry, HKCARD Electronics Co., Limited delivers high‑performance, re‑programmable (not one‑time burn) SIM cards that meet the most demanding standards of telecom operators, device OEMs, and IoT developers. Our range includes Writable IMSI SIM Cards, Writable Ki SIM Cards, Writable ICCID SIM Cards, Writable OP/OPc SIM Cards, Writable SPN SIM Cards, Writable MNC SIM Cards, Writable MCC SIM Cards, and many other programmable SIM card solutions—all available in standard form‑factors (2FF, 3FF, 4FF) and white‑label options.

 Why Choose HK Card for Your SIM Card Needs?

• Broad Compatibility – Works with GSM, UMTS, LTE, 4G LTE/WCDMA, 5G NR (R16 SA), and upcoming 6G trials.
• Full Re‑Programmability – Unlike “burn‑once” chips, our SIMs can be rewritten multiple times with PC/SC tools (e.g., pySim), supporting USIM/LTE, eSIM, and NFC functionalities.
• Extensive Customization – Choose from white SIM cards, blank SIM cards, dummy SIM cards, IoT/Evaluation SIM cards, multi‑network 4G/5G VO‑LTE versions, and custom 512 kB/256 kB/128 kB memory capacities.
• Industry‑Leading Experience – We are a recognized SIM card manufacturer and supplier serving MVNOs, network operators, device testers, and research labs worldwide.

 Core Product Portfolio

All products are available in bulk quantities and can be white‑labelled for private‑brand distribution.

 How Our Programmable SIM Cards Power the Future

1. 5G SA & NSA Networks – Our 5G NR 3GPP R16 SA 5G SIM Card supports the latest authentication vectors, enabling seamless handovers and enhanced security.
2. IoT & eSIM Deployments – Thin blank SIM cards, white label MVNO SIM cards, and eSIM formats cater to low‑power devices, remote monitoring, and OTA provisioning.
3. Rapid Lab Testing – Use pySim, sim programming tools, or java SIM card utilities to rewrite IMSI, Ki, OPc, SPN, MNC, and MCC values in seconds, accelerating device certification cycles.
4. Custom Solutions – From 512 kB SIM cards to 256 kB or 128 kB variants, we can tailor memory size, security keys, and network IDs for unique use‑cases.

Frequently Asked Questions (Q&A)

Q1: What does “re‑programmable SIM card” mean?
A: It means the SIM’s data (IMSI, Ki, OPc, ICCID, SPN, etc.) can be rewritten multiple times using standard PC/SC readers—perfect for testing, pilot runs, and iterative development.

Q2: Do you supply SIM cards that work with 5G SA networks?
A: Yes. Our 5G SA 128k SIM Card and 5G SA SIM Card are fully compliant with 3GPP Release 16 specifications.

Q3: Can I obtain free sample writable IMSI SIM cards?
A: We offer free sample kits for qualified customers. Contact us with your technical requirements and shipping details.

Q4: How do I program a SIM using pySim?
A: Use the open‑source pySim library to connect via a USB PC/SC reader, then write new IMSI, Ki, or OPc values by loading a CSV or JSON configuration file. Detailed code samples are available on our developer portal.

Q5: What form factors are available for blank SIM cards?
A: 2FF, 3FF, 4FF, Nano‑USIM, and custom SIM wallet NFC formats, all supplied on white SIM or blank SIM substrates.

Q6: Are your SIM cards compatible with IoT networks?
A: Absolutely. We provide IoT/Evaluation SIM cards, blank SIM cards, and SIM dummy variants optimized for low‑power, long‑life deployments.

Q7: How can I customise a SIM for a specific MVNO?
A: Our engineers can embed MNC, MCC, SPN, and OPc values tailored to your brand, then ship the cards in white label packaging.

Q8: What security certifications do your SIMs hold?
A: All cards meet ETSI TS 102 221 and ISO/IEC 7816 standards, with optional eSE/Secure Element integration for enhanced security.

Q9: Do you provide bulk pricing for large orders?
A: Yes. Volume discounts are available for bulk SIM orders starting at 10 k units. Request a quote for exact pricing.

Q10: How does HK Card ensure fast delivery to my location?
A: We maintain stocked warehouses in Hong Kong and Singapore, enabling express shipping to Asia‑Pacific, Europe, and the Americas within 48 hours of order confirmation.
