ToggleTechnical Specifications: The Core of Your Network
To ensure seamless integration with Open5GS and other private network cores, our SIM cards are engineered with the specific technical parameters required for secure authentication and network entry.
1. Advanced Algorithm Support
Our blank SIM cards are designed to support the essential XOR/Milenage authentication algorithms. This is critical for network engineers who need to manage subscriber identity securely within a private testing or production environment.
2. Full Programmability
We understand that customization is non-negotiable for R&D and private infrastructure. Our SIM cards support:
- Customizable IMSI (International Mobile Subscriber Identity)
- Customizable KI (Authentication Key)
- Customizable OPC (Operator Code)
This level of control allows you to provision your own users and devices without dependency on public carrier profiles, ensuring total control over your 5G SA deployment.
