Our Core Products: Engineered for Precision and Compatibility
At HKCARD, we understand that seamless network testing relies on high-quality SIM cards. Our product portfolio is designed to support the latest mobile standards, ensuring compatibility with 5G NR, 4G LTE, and legacy networks. Here’s an overview of our most sought-after solutions:
1. 128K/J 5G Test (U)SIM – 2FF, 3FF, 4FF
Our flagship 5G Test (U)SIM cards are built to accelerate 5G network deployment and device validation. Available in 2FF (standard), 3FF (micro), and 4FF (nano) form factors, these cards support 128K/J memory capacity, enabling advanced testing features such as packet core emulation, QoS verification, and multi-band network slicing. Ideal for 5G base station testing, UE conformance, and IoT device certification, our 5G Test (U)SIMs ensure accurate, repeatable results in both lab and field environments.
2. 5G Test USIMs
Specifically optimized for 5G standalone (SA) and non-standalone (NSA) networks, our 5G Test USIMs comply with 3GPP standards (TS 31.102, TS 31.103) and support 5G AKA authentication, SUCI/SUPI privacy protection, and enhanced mobile broadband (eMBB) testing. These cards are widely used by network operators to validate 5G call setup, data throughput, and latency, ensuring their networks meet the performance benchmarks required for next-gen applications like AR/VR and autonomous vehicles.
3. 128k Mileage Algorithm 4G LTE Blank Programmable USIM SIM Card
For 4G LTE network testing and automotive telematics, our 128k Mileage Algorithm USIM Cards are a game-changer. Pre-loaded with customizable mileage calculation algorithms, these programmable blank SIMs enable accurate tracking of vehicle mileage, fuel consumption, and driver behavior—critical for fleet management, insurance telematics, and emissions testing. With support for OTA (Over-The-Air) programming, clients can easily update algorithms and configurations without physical card replacement.
4. 128K/J LTE Test (U)SIM – 4FF
Designed for compact devices like smartphones, wearables, and IoT sensors, our 128K/J LTE Test (U)SIM in 4FF (nano) form factor is the go-to choice for 4G LTE device testing. These cards support LTE Cat-M1, NB-IoT, and LTE-Advanced Pro, making them ideal for low-power wide-area (LPWA) network validation, IoT device interoperability testing, and mobile application performance analysis.
5. 128k Blank Mobile Phone Sim Cards
Our 128k Blank Mobile Phone SIM Cards offer unmatched flexibility for custom programming. With 128K memory and compatibility with 2G, 3G, 4G, and 5G networks, these blank SIMs can be personalized with client-specific ICCIDs, IMSIs, and Ki values via our secure programming tools. Perfect for MVNOs, mobile virtual network enablers (MVNEs), and bulk SIM card distributors, they support rapid deployment of prepaid plans, data-only services, and international roaming solutions.
