Blank Programmable SIM Card (Mini / Micro / Nano) — Writable VoLTE Test USIM, 3GPP R16

HKCARD ELECTRONICS CO., LIMITED provides a blank programmable SIM/USIM card designed for VoLTE/IMS testing and provisioning in authorized telecom environments. This is a rewritable test card that supports 3GPP Release 16 (R16)-aligned requirements and can be supplied as a 3-in-1 form factor: Standard SIM (2FF), Micro SIM (3FF), and Nano SIM (4FF) in one punch-out card.

For telecom operators, integrators, and engineering teams, a programmable VoLTE test card helps speed up validation work by allowing controlled writing of key IMS-related parameters—without needing multiple card types for different devices.

Compliance note: This product is intended for telecommunication operators/companies, authorized labs, and approved private networks. All credential provisioning and network access must follow applicable laws and operator security policies.

Key Capabilities (VoLTE / IMS Testing Focus)

Standards & Network Features

• Support: 3GPP Release 16 (R16)
• Support: VoLTE (VoLTE readiness depends on your network/test setup and device capabilities)

UST Service Support

• Supports UST services 122–135 (as defined in relevant 3GPP USIM/UST service tables for USIM applications), suitable for operator-driven feature control and test scenarios.

Writable / Programmable Fields (Project-Dependent)

This card can be written with IMS/VoLTE-related parameters such as:

• DOMAIN
• IMPI (IP Multimedia Private Identity)
• IMPU (IP Multimedia Public Identity)
• P-CSCF (Proxy Call Session Control Function)
• AD and other related items based on your provisioning profile

(Exact writable items depend on your card profile, security settings, and provisioning tools.)

3-in-1 Plug-in Size (2FF / 3FF / 4FF)

To simplify procurement and device coverage, HKCARD offers a 3-in-1 punch-out design:

• Standard SIM (2FF)
• Micro SIM (3FF)
• Nano SIM (4FF)

This is ideal for teams testing multiple device generations (phones, CPE, IoT modules) across different SIM tray types.

Typical Applications

This blank programmable VoLTE card is commonly used by:

• Telecommunication operators / telecom companies
• Device manufacturers and QA teams (VoLTE feature validation)
• Network integration teams (IMS configuration checks in controlled environments)
• R&D laboratories (repeatable provisioning and regression testing)

Mini FAQ 

Q: What is a blank programmable VoLTE SIM/USIM card?
A: It’s a rewritable test SIM/USIM that can be provisioned with required subscriber and IMS parameters to support VoLTE/IMS testing in authorized environments.

Q: What does “3-in-1 SIM” mean?
A: One card body can be punched into 2FF, 3FF, or 4FF, reducing the need to stock multiple form factors.

Q: Can I write IMPI/IMPU and P-CSCF values?
A: Yes—this product supports writing IMS-related fields such as IMPI, IMPU, Domain, and P-CSCF, depending on your configuration and provisioning workflow.
