Global telecom operators, IoT developers, and hardware engineers require reliable smart card hardware. HKCARD ELECTRONICS CO.,LIMITED (HKCARD) works as a sim cards wholesale supplier sim card blank, providing direct-from-factory solutions. Whether you need standard consumer SIMs, lab-ready test cards, or specific programmable profiles, we supply the hardware that keeps your networks and devices running.
Below is an overview of our core products, supported network technologies, and physical card formats.
1. Multi-Network and 5G Solutions for Global Connectivity
Modern devices must connect across borders and different network generations. HKCARD manufactures a wide range of network-specific and multi-network cards to handle these transitions smoothly.
- 4G and VoLTE Compatibility: Our multi-network 4g volte sim card (also referred to as a multi network 4g volte sim card or multinetwork 4g volte sim card) ensures stable voice-over-LTE connections globally. If you need broad backward compatibility, we produce cards supporting nr/lte/cdma/evdo/gsm/wcdma standards.
- Legacy and Specific Networks: We supply standard cdma sim card units and usim 4g cards for specific regional network requirements.
- Next-Generation Deployments: For 5G rollouts, HKCARD offers the nr sim, nsa card (Non-Standalone architecture), and the advanced 5g usim.
2. Professional Testing Tools: WCDMA and Test SIMs
Before launching a new mobile device or rolling out a network, rigorous lab testing is required. HKCARD provides the exact tools telecom engineers need for base station and handset verification.
- Test and Programmable SIMs: We supply the dedicated test sim (or test sim card) used in lab environments. For developers and security researchers, our programmable sim allows you to write custom IMSI, Ki, OPC, and network parameters. This includes advanced models like the programmable sim card 5g.
- WCDMA Validation: Our cards are specifically configured for wcdma testing and complete wcdma functional testing to ensure older network fallbacks operate correctly. We also provide standard ki-sim for authentication setups.
- Hardware Integration: To program these cards, engineers require reliable hardware. We supply and recommend the omnikey 3121 reader writer, an industry-standard USB smart card reader that integrates perfectly with our blank SIMs for rapid read/write operations.
3. Blank SIM Cards and Form Factors: 2FF, 3FF, 4FF, and eSIM
Device requirements vary, which is why we provide universal sizing options to fit any hardware slot. We supply raw materials globally, commonly searched as blankocard or blanko sim karte.
- Standard Sizes: We offer individual 2ff sim card (Standard), 3ff sim card (Micro), and 4ff sim card (Nano) formats.
- Universal Formats: To simplify inventory, we highly recommend our blank white triple format sim or simcard trio halfcard. These are pre-cut to snap out into whichever size the end-user needs.
- Emerging Tech: As the industry moves toward digital provisioning, HKCARD also provides blank esim solutions for modern devices.
4. Specialized SIM Profiles and Wholesale Supply
Different network providers have exact specifications for memory capacity, security protocols, and open-source frameworks. HKCARD manufactures specific profiles to meet these exact telecom standards.
- Capacity and Custom Profiles: We produce the 128kusim for high-capacity storage, the 64k simtrio for wireless fixed-line post, and the triplesim plug 64k tmo uicc 5g built for 5G UICC standards.
- SysmoISIM and Open-Source Frameworks: For open-source mobile communications (like Osmocom), we supply the widely used sysmoisim and sysmosim lines. This includes specific hardware versions like the sysmoisim-sja2, sysmoisim-sja5, sysmousim, and the sjs1.
- Security and Privacy: We manufacture the psam sim (Purchase Secure Access Module) for high-security terminals. For enhanced 5G subscriber privacy, we offer specialized SUCI (Subscription Concealed Identifier) profiles, including the u mobile suci sim, umobile suci sim card, and the 711 suci.
