HKCARD ELECTRONICS CO.,LIMITED (HKCARD) provides blank SIM card products, programmable SIM solutions, and operator-grade USIM SIM card options for telecom, MVNO, IoT, testing labs, and SIM distributors. Whether you need telecom SIM cards for deployment or engineering SIMs for validation, HKCARD supports stable supply, clear specs, and consistent batches.

1) Blank SIM Card Types and Card Body Formats

HKCARD offers blank sim stock for personalization, printing, and lab use, including common sizes and packaging options.

Common choices

  • blank sim card (un-personalized, ready for encoding)
  • blank white / sim card white (for branding and overprinting)
  • nano card sim and other cut sizes (2FF/3FF/4FF)
  • trio sim (multi-size in one card body)
  • sim sim card requests (often listed in BOMs as a generic SIM card item)

Special format requests

  • triplesim plug 64k tmo uicc 5g (available by requirement/spec confirmation)

If you share your target market, form factor, and chip requirements, HKCARD can recommend the right blank card body and lead time.

2) USIM, LTE USIM, 5G USIM, and Multi-Network 4G VoLTE SIM Cards

For network-facing projects, HKCARD supplies cards designed for LTE/5G authentication and IMS services.

Network-ready SIM options

  • usim sim card for LTE and modern core networks
  • lte usim for LTE deployments and device testing
  • 5g usim for 5G-capable devices and profiles
  • 5g ready UICC options for forward compatibility
  • multinetwork 4g volte and multinetwork 4g volte sim card configurations
  • multi-network 4g volte sim card supply for multi-operator or multi-profile needs
  • u sim card variants (commonly requested naming for USIM/UICC products)

Legacy and regional needs

  • cdma sim card requests (supported based on local specification and application)

Testing support

  • Cards can be provided for volte conformance testing when stable, repeatable behavior is required in lab verification and device certification workflows.

3) Programmable SIM, SIM Card Programmer/Writer, and Basic Workflow

HKCARD supports teams that encode and personalize cards in-house, including projects using a sim card programmer or sim card writer.

Typical questions: “how to program a sim card?”
In most production setups, the flow looks like this:

  1. Choose a compatible programmable sim
  2. Connect a sim card programmer / sim card writer
  3. format sim as needed (per your toolchain)
  4. Load profiles/keys (according to your security process)
  5. Verify on target devices and networks

Development-oriented options

  • java sim for applet-based requirements and controlled feature deployment
  • sja2-based cards (available when your project spec calls for it)

If you share your tooling model and expected memory/profile requirements, HKCARD can help match the correct programmable card type.

4) SUCI / SUSI / SYSMOUSIM Requests and Spec Matching

Some customer documents list non-standard or project-specific naming. HKCARD can match these requests to the right card type and profile after spec review.

Examples HKCARD can support by specification:

  • suci sim
  • susi sim
  • sysmousim

Send your requirement sheet (network, profile type, form factor, and use case). HKCARD will confirm what is needed before sampling or mass production.

5) White Label, Custom SIM Card, Bulk Orders, and Wholesale Supply

HKCARD works with operators, integrators, and resellers that need consistent long-term supply.

Supply models

  • white label sim cards (branding-ready, your design/packaging)
  • custom sim card (layout, printing, packaging, and spec-based configuration)
  • bulk sim supply for deployment and distribution
  • Reliable sourcing for partners looking for sim card suppliers
  • Support for distributors needing a sim cards wholesale supplier
