- 4FF LTE Test USIMs: Designed for modern smartphones and IoT devices, our 4FF (Nano-SIM) test cards deliver seamless compatibility with 4G/LTE networks, ensuring reliable performance across global frequency bands.
- 64K/J LTE Test (U)SIM – Plug-In: Perfect for lab setups requiring easy insertion/removal, these plug-and-play SIMs combine durability with fast data reprogramming capabilities.
- Blank Programmable USIM/SIM Cards: Need custom data? Our blank programmable SIMs let you configure operator-specific algorithms (including Milenage), XOR logic, or network parameters—tailored to your unique testing workflows.
No matter if you’re working with Test SIM/USIM Karten für openLTE or need support for dual Milenage and XOR algorithms, HKCARD has the right test SIM to accelerate your project.
Why Engineers Choose HKCARD: Precision, Flexibility, and Reliability
When it comes to testing LTE devices, accuracy is non-negotiable. Here’s what sets HKCARD apart:
1. Advanced Algorithm Support
Our test SIMs are engineered to support 128k Mileage Algorithm 4G LTE and other critical protocols like Milenage, XOR, and custom operator-specific algorithms. Whether you’re validating authentication vectors for CMW500 testers or stress-testing network resilience, our SIMs ensure consistent, repeatable results.
2. Multi-Form Factor Compatibility
From Mini, Micro, and Nano Blank 4G Test SIM Cards to Mini-UICC and 4FF formats, we cover every device type—from legacy phones to the latest 5G-ready smartphones and IoT modules. This versatility makes us the ideal choice for labs testing across multiple device generations.
3. Customizable & Programmable Solutions
At HKCARD, we understand that no two testing scenarios are identical. That’s why our Blank Programmable USIM SIM Cards allow you to reprogram data (including ICCID, IMSI, Ki, and operator keys) on-demand. Whether you need a single prototype or bulk orders, we deliver tailored solutions that align with your project timeline.
4. Global Standards Compliance
All our test SIMs adhere to ETSI, 3GPP, and ITU standards, ensuring seamless integration with leading test equipment like CMW500, R&S, and Anritsu. This compliance minimizes setup time and eliminates compatibility issues—critical for labs working under tight deadlines.
