What HKCARD Supplies (Core Product Scope)

Programmable / Re-programmable SIM Cards (Not OTP)

We focus on re-writable SIM/USIM products designed for professional environments where profiles, parameters, and applets may need to be updated repeatedly.

Programmable SIM Cards using PC/SC tools (e.g., pySim)
Works with common PC/SC smart card readers and SIM programming workflows
Suitable for SIM personalize tools, test benches, and controlled production processes

Note: HKCARD products are intended for authorized networks and lawful testing. We do not support illegal SIM cloning or unauthorized access to carrier networks.

Writable Data Fields We Commonly Support

Many customers search for specific writable items. HKCARD can provide solutions aligned to these requirements (depending on card OS, security policy, and project scope):

Writable IMSI SIM Cards
Writable imsi sim cards free (commonly meaning free tools/workflows like pySim or evaluation-oriented setup—please tell us your lab goal)
Writable Ki SIM Cards
Writable ICCID SIM Cards
Writable OP or OPc SIM Cards (MILENAGE projects)
Writable KEY SIM Cards
Writable SPN SIM Cards
Writable MNC SIM Cards / Writable MCC SIM Cards

If you are building a test environment (Open5GS, srsRAN, Amarisoft, private EPC/5GC, etc.), tell us your target authentication method and network type so we can recommend the right SIM platform.

4G / LTE / WCDMA USIM Cards (Not GSM-Only)

HKCARD supplies USIM / LTE SIM Cards (not GSM-only) and related options:

4G LTE/WCDMA blank cards
4G GSM SIM card (where required)
usim 4g, usimlte, 128k usim / 128kusim, 256k sim, 512k sim
multi network 4g volte sim card options for testing
Products commonly used for 4g volte tester workflows and handset/module validation

5G SIM Cards (SA / NR) — 3GPP R16 Focus

For advanced projects, HKCARD provides:

Programmable SIM card 5G
Custom SIM cards for 4G LTE & 5G NR Networks
HKCARD’s Programmable SIM Cards for 5G Networks
Programmable 5G NR 3GPP R16 SA 5G SIM Card
5g sa 128k sim, 5g sa sim card, 5g usim
Support for SUCI SIM card requirements (including searches like “suci sim คือ”)

If you are targeting 5G Standalone, share your PLMN (MCC/MNC) plan and 5GC settings so we can align the card profile and memory size selection (128K/256K/512K).

IoT / Evaluation SIM Cards & Special Test Cards

HKCARD supports engineering and lab needs across IoT and device bring-up:

IoT/Evaluation SIM Cards
UIM card, RUIM card, CDMA SIM card (project-dependent)
TD SIM (region/project dependent)
usim test solution guidance (card selection + test compatibility)

We also supply dummy SIM / SIM dummy / dummy sim card for legitimate device tray fit tests, demos, and lab workflows (often searched as fake sim, dummy sim card airtel, offbrand sim). If you need a non-network functional “empty SIM card” purely for mechanical testing, ask us for the correct dummy type.
