As global telecommunications shift from legacy networks to advanced 5G infrastructures, mobile network operators (MNOs), MVNOs, and IoT developers require reliable, adaptable smart card technology.
HKCARD ELECTRONICS CO.,LIMITED (HKCARD) operates as a leading 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 running.
Below is an overview of our core products, supported network technologies, and physical card formats.
1. 5G, 4G LTE, and Multi-Network SIM Solutions
Modern devices need to connect across borders and across different network generations. HKCARD manufactures a wide range of network-specific and multi-network cards to handle these transitions smoothly.
Our product line includes the multi-network 4g volte sim card (also referred to as multi network 4g volte sim card or multinetwork 4g volte sim card), which ensures stable voice-over-LTE connections globally. For broad backward compatibility, we produce cards that support nr/lte/cdma/evdo/gsm/wcdma standards.
If your focus is on legacy or specific network types, we supply standard cdma sim card units and usim 4g cards. For next-generation deployments, HKCARD offers the nr sim, nsa card (Non-Standalone architecture), and the advanced 5g usim.
2. Wholesale Supplier for Blank and Programmable SIM Cards
For developers, security researchers, and private network operators, having an unlocked, writable card is essential. HKCARD specializes in the manufacturing of programmable sim cards.
Our programmable sim card 5g allows engineers to write their own IMSI, Ki, OPC, and network parameters. We supply raw materials globally, commonly searched as blankocard or blanko sim karte. Whether you need a standard ki-sim for authentication setups or complex customized profiles, we provide the blank media necessary for your projects.
3. Comprehensive Form Factors: 2FF, 3FF, 4FF, and eSIM
Device requirements vary, which is why we provide universal sizing options to fit any hardware slot.
- 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 away from physical plastics, HKCARD also provides blank esim solutions for modern device provisioning.
4. Advanced Testing: WCDMA, Test SIMs, and Hardware Tools
Before rolling out a network or launching a new mobile device, rigorous lab testing is required. HKCARD provides the exact tools telecom engineers need for base station and handset verification.
We supply the dedicated test sim card (or test sim) used in lab environments. This includes cards specifically configured for wcdma testing and complete wcdma functional testing to ensure older network fallbacks operate correctly.
To program these test 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.
5. Specific Profiles, Storage Options, and Custom Smart Cards
Different network providers have exact specifications for memory capacity and security protocols. HKCARD manufactures specific profiles to meet these exact telecom standards.
Capacity and specialized profiles:
- 128kusim: High-capacity cards for extended phonebook and network data storage.
- 64k simtrio for wireless fixed-line post: Optimized for fixed wireless terminals.
- triplesim plug 64k tmo uicc 5g: A versatile 64K solution built for 5G UICC standards.
SysmoISIM and Security 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. We also produce the psam sim (Purchase Secure Access Module) for high-security payment and transit terminals.
SUCI Configurations:
For enhanced 5G subscriber privacy, we manufacture cards with specialized SUCI (Subscription Concealed Identifier) profiles, including the u mobile suci sim, umobile suci sim card, and the 711 suci.
