This product is a blank, writable programmable SIM/USIM card designed for VoLTE and IMS-related testing. It is intended for telecom operators, solution companies, and engineering teams who need to build and validate their own subscriber profiles in a lab or private network environment.
The card ships blank (no active profile). To use it, you’ll need to personalize it with your own data and provision the subscriber in your network system.
Standards and network features
- 3GPP support: aligned with 3GPP Release 16 (R16)
- VoLTE support: suitable for IMS/VoLTE test scenarios
- UST services: supports USIM service control items typically referenced in 3GPP UST service range 122–135 (project-dependent configuration)
Writable / programmable items (typical IMS fields)
Depending on your tools and access permissions, you can write IMS-related parameters such as:
- DOMAIN
- IMPI
- IMPU
- P-CSCF
- AD and other related items (as required by your IMS/core configuration)
This makes the card useful when you’re validating IMS registration behavior, VoLTE call flows, or device compatibility in a controlled environment.
SIM sizes: 3-in-1 (2FF/3FF/4FF)
Each card is supplied in a punch-down format:
- 2FF (Mini / Standard SIM)
- 3FF (Micro SIM)
- 4FF (Nano SIM)
One card can be used across different phones, modems, and test fixtures.
Application / intended users
- Telecommunication operators
- Telecom solution companies and engineering labs
- Teams running VoLTE/IMS validation, private LTE trials, or device certification testing
If you tell us your VoLTE test goal (IMS registration only, voice call setup, interoperability checks) and your programming setup (reader/writer + software), HKCARD ELECTRONICS CO.,LIMITED can recommend the right blank card option for your project.
