2G/3G/4G/5G Ver 4.1.5 SIM card software

When you’re bringing up a new device, validating a modem, or running repeatable network tests, you don’t want to burn a new card every time you change one parameter. That’s exactly what this writable, programmable blank SIM card is made for.

At HKCARD ELECTRONICS CO., LIMITED, we supply rewritable blank SIMs that can be programmed with standard SIM readers and software tools, then erased and written again for the next round of testing.

What this card is for

  • Telecom and device R&D / QA testing
  • IoT and M2M prototyping
  • Network registration and authentication workflow checks
  • SIM application and STK development (project-dependent)

What you can program (typical fields)

Using your SIM programming setup, you can write common parameters such as:

  • IMSI
  • ICCID
  • Ki
  • OPC / OP
  • Other data fields required by your test profile

Note: network acceptance depends on your core network/carrier configuration and the profile you write.

Key points (in plain terms)

  • Fully rewritable: made for repeated programming and lab use
  • Multi-network support: works across GSM (2G), UMTS (3G), and LTE (4G) scenarios (subject to configuration/support)
  • Durable for testing: designed for high rewrite counts in long test cycles
  • 3-in-1 format: full-size with punch-down to Micro and Nano

Specifications

  • COS: Pre-installed COS
  • Supported Networks: GSM (2G), UMTS (3G), LTE (4G)
  • SIM Format: 3-in-1 (Standard / Micro / Nano)
  • Write Cycles: > 100,000
  • Data Retention: > 10 years
  • Memory/MCU resources:
    • 256 bytes internal data RAM
    • 2048 bytes external data XRAM
    • 80K bytes flash (COS area + user data area)

What you’ll need

To use it as intended, you’ll typically need:

  • A compatible SIM card reader/writer
  • Programming software/tooling suitable for your workflow

If you tell us your reader model and what you plan to test (2G/3G/LTE attach, IMS/VoLTE lab work, IoT, etc.), we can recommend the best matching card option from our stock.
