HKCARD programmable 5G NR R16 SA USIM cards in 2FF/3FF/4FF, pySim/Open5GS compatible

At HKCARD ELECTRONICS CO.,LIMITED, our core business is supplying test SIM/USIM cards for mobile phone development, lab validation, and production-line testing. If your team needs a stable card profile for repeatable instrument tests—or blank cards for controlled programming—we can support you with the right format and network type.

Our main products

  • Phone test SIM cards
  • LTE test cards (LTE-USIM)
  • WCDMA test cards
  • Blank test SIM/USIM cards (for engineering programming and verification)

These products are widely used by device manufacturers, R&D teams, test labs, and solution companies that need consistent results during debugging and mass production.


Featured model: TD-LTE#1 Phone Test Card (LTE-USIM CARD)

Product name: LTE phone test card (LTE-USIM CARD)
Model: TD-LTE#1 test card
Network focus: TD-LTE test scenarios (project dependent)

This LTE-USIM test card is designed to work in test environments where phones, modules, or CPE devices are verified using network emulation instruments. Instead of relying on a live operator SIM and a public network, engineers can keep the test conditions controlled and repeatable.

Typical use

  • Factory and production-line checks (fast and consistent)
  • Lab testing with radio communication testers
  • Device bring-up and troubleshooting during R&D

Why LTE test cards became a standard tool

LTE (Long Term Evolution) is the mainstream technology used in the transition from 3G to 4G and beyond. For engineers, LTE testing usually focuses on practical goals such as:

  • reducing connection setup delays
  • improving user data rate and system capacity
  • improving coverage and stability in real devices
  • lowering operational complexity in test and validation workflows

In production, a test SIM/USIM helps create a clean test path “instrument → device,” which reduces test time and avoids variables from public networks.


3G and 2G test card options (WCDMA, EVDO, TD-SCDMA, GSM, CDMA)

Different markets and legacy products still require older network testing. In China and many other regions, 3G technologies have included:

  • WCDMA
  • EVDO
  • TD-SCDMA

And for non-3G testing, common options include:

  • GSM test cards
  • CDMA test cards

If you tell us your device platform and test target (LTE/WCDMA/GSM, etc.), we can recommend the right test card type and form factor.
