When building or expanding a native TDD-LTE / 5G SA (Standalone) core network—especially deployments based on Open5GS—the SIM credentials and authentication methods must match the requirements of your core. HKCARD ELECTRONICS CO.,LIMITED/HKCARD provides blank LTE/5G SIM cards designed for professional programming and integration into 4G/5G environments.
This article explains the key items in a typical delivery, what the SIM must support, and why XOR/Milenage with customizable parameters is essential for many 5G SA scenarios.
1) What’s Included in the Batch
1.1 SIM Blank Batch (LTE/5G)
HKCARD ELECTRONICS CO.,LIMITED/HKCARD supplies blank 4G/5G SIM cards that can be provisioned for advanced network use cases.
Key capability requirement:
- XOR / Milenage authentication algorithm support (for LTE/5G authentication workflows)
These blank SIMs are intended for environments where you need to write your own operator or private-network credentials rather than using pre-personalized consumer SIMs.
1.2 SIM Programming Tool
To program SIM profiles efficiently and reliably, the batch includes:
- 1× Industrial USB SIM Card Reader/Writer
- PC software for SIM provisioning and parameter writing
This combination helps ensure repeatable personalization, testing, and deployment for lab or field rollouts.
2) 4G and 5G SIM Cards Supporting 5G SA Mode
5G SA (Standalone) mode requires the network and SIM to work together with correct authentication data and subscription parameters. The blank SIM cards from HKCARD ELECTRONICS CO.,LIMITED/HKCARD are suitable for:
- 4G LTE networks
- 5G networks
- 5G SA (Standalone) mode use cases, depending on how you personalize the credentials and subscription settings
3) Why XOR/Milenage Matters for Open5GS and 5G SA
If your network core runs on a native TDD-LTE / 5G SA platform (Open5GS), your SIM cards must support the correct authentication mechanism and allow credential customization.
3.1 Required Customizable SIM Parameters
For 5G SA deployment and Open5GS integration, SIMs often need to support writing or customizing:
- IMSI (International Mobile Subscriber Identity)
- KI (Subscriber authentication key)
- OPC (Operator Code / Derived Operator Code, depending on configuration)
HKCARD ELECTRONICS CO.,LIMITED/HKCARD blank SIMs are designed to be programmed with these parameters so you can align SIM identity and authentication with your core-network configuration.
3.2 Deployment Benefits
Using programmable blank SIMs with XOR/Milenage support helps you:
- Deploy private LTE/5G networks with controlled subscriber management
- Run lab validation and interoperability tests before scaling
- Perform credential provisioning for dedicated projects where carrier SIMs are not suitable
- Maintain flexibility for IMSI ranges and operator credential planning
4) Typical Use Cases
HKCARD ELECTRONICS CO.,LIMITED/HKCARD blank LTE/5G SIM solutions are commonly used in:
- Open5GS-based 5G SA testbeds
- Private 4G/5G networks (industrial, campus, enterprise)
- R&D labs validating SIM provisioning workflows
- Small-scale rollouts requiring custom IMSI/KI/OPC management
