HKCARD ELECTRONICS CO., LIMITED supplies writable, programmable blank LTE USIM cards for professional telecom use cases such as network and device testing, R&D validation, and authorized lab environments. These cards support 4G LTE (FDD), WCDMA, and GSM test scenarios and are available in a convenient 3-in-1 (tri-cut) format: Standard SIM (2FF), Micro SIM (3FF), and Nano SIM (4FF).
For telecom operators, integrators, and engineering teams, a programmable test USIM helps streamline workflows by allowing controlled personalization (where authorized), while custom logo printing keeps your test assets clearly identified and easy to manage across teams and test stations.
Important note: This is a professional engineering product. It is intended for authorized testing and provisioning only. Please do not purchase if you are unfamiliar with SIM/USIM personalization, security requirements, and compliance obligations. HKCARD does not support illegal use, unauthorized network access, or device bypass/unlocking activities.
Product Highlights (Designed for Engineering & Lab Work)

- Ideal for testing across different devices without keeping separate inventories
Network Compatibility (Testing Use)
- 4G LTE (FDD) / WCDMA / GSM
- Suitable for system testing, device verification, and controlled network simulation environments
Memory Options
- 32K / 64K / 128K / 256K (project-dependent)
Supported Algorithms (Project-Dependent)
- COMP_V1 / COMP_V2 / COMP_V3 / CMCC_COMP_V0
(Availability depends on card profile and customer requirements.)
Writable / Programmable Data (Typical Personalization Items)
With appropriate authorization and tooling, programmable test cards can be provisioned with items such as:
- IMSI
- ICCID
- PIN / PUK
- Additional operator/test-profile fields (e.g., service parameters) depending on your application and security policy
Exact writable fields vary by card OS/profile and the provisioning environment.
Custom Printing & Marking (Branding + Traceability)
This offering can include one custom design printing fee, covering:
- Custom logo and artwork on both sides
- 4+4 offset printing (full color front and back)
- Optional laser marking for identifiers such as ICCID/IMSI (common for asset tracking and batch management)
Custom printing helps factories and labs reduce handling mistakes by clearly separating different test profiles and batches.
Typical Applications
- Telecom operators and telecom engineering teams
- Mobile phone factories (production line testing)
- IoT module and CPE/router validation
- RF/protocol labs and device QA teams
- Authorized private LTE environments and network simulation setups
