Frequently Asked Questions (FAQ)

What is a programmable 5G SIM card?

A programmable 5G SIM card is a blank SIM card that can be configured with custom network parameters. Unlike carrier-locked SIM cards, programmable cards allow you to define your own IMSI, Ki, OPc, and other authentication values. This flexibility is essential for:

• Private 5G network operators
• Telecommunications researchers
• Network testing laboratories
• IoT solution developers
• Enterprise IT departments

What is the difference between USIM and ISIM?

USIM (Universal Subscriber Identity Module):

• Handles standard 3G/4G/5G network authentication
• Stores subscriber identity (IMSI)
• Contains authentication keys (Ki, OPc)
• Supports network selection and roaming

ISIM (IP Multimedia Services Identity Module):

• Specifically designed for IMS services
• Enables VoLTE (Voice over LTE)
• Supports VoNR (Voice over New Radio)
• Contains IMS-specific credentials

Modern 5G deployments typically require cards supporting both USIM and ISIM applications.

Are your SIM cards compatible with 3GPP Release 16?

Yes, our Programmable 5G NR 3GPP R16 SA sim cards fully comply with 3GPP Release 16 specifications, supporting:

• 5G Standalone (SA) network authentication
• 5G Non-Standalone (NSA) mode
• Enhanced security features
• Network slicing capabilities
• Improved IoT and URLLC support
