Programmable Blank 5G ISIM Card – 3GPP Release 16 SA/NSA VoNR/VoLTE Triple-Cut USIM for Telecom Operators by HKCARD ELECTRONICS CO., LIMITED

The successful rollout of 5G NR networks depends heavily on proper IMS (IP Multimedia Subsystem) configuration for voice services. Whether deploying 5G Standalone (SA) or Non-Standalone (NSA) architecture, operators need SIM cards that can be fully programmed with accurate IMS credentials. HKCARD ELECTRONICS CO., LIMITED offers a professional-grade programmable blank 5G ISIM Card that allows authorized engineers to write ICCID, DOMAIN, IMPI, IMPU, P-CSCF, AD, and other critical IMS parameters. Built to 3GPP Release 16 standards and compatible with 2G, 3G, 4G, and 5G networks, this writable USIM/ISIM card is the ideal solution for network testing, VoNR validation, device certification, and commercial 5G voice service deployment.

Important Notice: This product is intended exclusively for telecom operators and qualified professional engineers. It requires technical knowledge of ISIM architecture, 5G authentication, and SIM programming tools. If you are not familiar with these concepts, please do not purchase this card.

Full 5G NR Support with 3GPP Release 16 Compliance for SA and NSA Networks

This programmable 5G ISIM card is engineered to the latest 3GPP Release 16 specifications, ensuring full compatibility with both 5G Standalone (SA) and Non-Standalone (NSA) deployments. It supports:

• 5G-AKA authentication for pure 5G core networks
• EPS-AKA for NSA mode anchored to 4G LTE
• SUPI and SUCI privacy protection mechanisms
• Native VoNR (Voice over New Radio) and VoLTE service enablement
• Seamless fallback between 5G, 4G, 3G, and 2G networks

The dual USIM + ISIM application architecture allows the card to handle both data connectivity and IMS-based voice services on a single physical card, making it highly efficient for operators transitioning from 4G to full 5G voice solutions.

 Native ISIM Application – Write Complete IMS Parameters Including IMPI, IMPU, DOMAIN and P-CSCF

Unlike standard USIM cards, this blank 5G ISIM card features a fully accessible ISIM application, giving engineers complete control over IMS configuration. You can directly program the following critical parameters:

• DOMAIN – Home IMS domain name
• IMPI – IMS Private Identity (used for authentication)
• IMPU – One or more IMS Public Identities (SIP URIs or TEL URIs)
• P-CSCF – Proxy-CSCF address for IMS registration
• AD – Administrative Data for service configuration
• ICCID – Unique card identifier (laser printable)

These parameters enable proper IMS registration, SIP signaling, and voice service activation on both VoNR and VoLTE networks. Programming is performed using standard professional SIM writing tools, allowing operators to replicate exact commercial network profiles in test environments.

 Triple-Cut 2FF/3FF/4FF Design – One Card Supports All Common SIM Form Factors

Modern testing requires flexibility across device types. This card ships as a 3-in-1 triple-cut format, allowing users to easily detach the required size without adapters or risk of damage:

• Standard SIM (2FF) – Ideal for industrial modules and legacy devices
• Micro SIM (3FF) – Commonly used in mid-range devices and routers
• Nano SIM (4FF) – Standard for current 5G smartphones and compact IoT modules

Material: High-quality PVC with 6-pin gold-plated contacts
Operating System: Native OS optimized for speed and security
Memory Capacity: Available in 64K, 128K, and 256K variants (contact us for specific needs)

The precision die-cut design ensures reliable electrical contact in all three sizes, making this card extremely practical for labs that test multiple device categories.

 Exclusively for Telecom Operators – Professional 5G Network Testing and Deployment Tool

This programmable blank 5G ISIM card is manufactured specifically for legitimate operator use cases, including:

• 5G SA and NSA core network validation
• VoNR and VoLTE service testing
• IMS registration and P-CSCF discovery verification
• Device certification and GCF/PTCRB testing
• Private 5G network deployment for enterprises and campuses
• MVNO IMS profile development
• Inter-RAT handover and fallback testing

The card is not intended for consumer use or unauthorized network activities. It is a professional engineering tool for organizations with proper telecommunications licensing and technical expertise.
