Product Use and Packaging

Our standard off – the – shelf programmable SIM cards are sold in packs of 1,These are mainly designed for R & D, testing, and laboratory purposes. They offer a cost – effective and convenient option for developers and researchers to experiment with different network scenarios and card functionalities.

However, for actual trial runs or large – scale production in both private and public cellular network operations, network operators usually require a large number of personalized SIM cards. We understand the unique needs of each operator and can provide customized solutions to meet their specific requirements.

Customization Capabilities

Network Compatibility

We can supply SIM/USIM/ISIM/HPSIM products suitable for any type of network. Whether it’s the legacy 2G networks, the more advanced 3G and 4G networks, the cutting – edge 5G networks, or even the specialized GSM – R networks, our cards are fully compatible. This wide range of compatibility ensures that our customers can rely on us for all their network – related SIM card needs.

Customization Details

1. Minimum Order Quantity: The minimum order quantity for our customized SIM card products is 1 units. This allows us to efficiently manage the production process while still providing cost – effective solutions for our customers.
2. Technical Customization:
   
   • Authentication Algorithm and Keys: Customers can choose the authentication algorithm and the related key material (such as K, OP/OPc). This ensures enhanced security and compatibility with their specific network infrastructure.
   • Identification Ranges: We can customize the ranges of IMSI (International Mobile Subscriber Identity), ICCID (Integrated Circuit Card Identifier), MSISDN (Mobile Subscriber Integrated Services Digital Network Number), etc. to meet the operator’s internal numbering and identification systems.
   • File Configuration: The files on the cards can be specifically configured. For example, operator/network selection preferences (EHPLMN – Equivalent Home Public Land Mobile Network, FPLMN – Forbidden Public Land Mobile Network, etc.) can be set. Additionally, IMS – related configurations (IMPI – IP Multimedia Private Identity, IPUI – IP Multimedia Public Identity, etc.) and 5G – related configurations (SUCI – Subscription Concealed Identifier, etc.) can be tailored according to the network requirements.
   • OTA Security: Over – the – Air (OTA) security configuration, including key materials, key lengths, and algorithms, can be customized. This is crucial for ensuring the secure and seamless operation of the SIM cards in the network.
   • Pre – installed Java Applets: We can pre – install Java applets on the cards. These applets can add additional functionality to the SIM cards, such as enabling new services or enhancing user experience.
3. Physical Customization:
   
   • Form – Factor: Customers can choose between half – size or full – size plastic cards. We also offer different cutting options like bridge cut, seamless cut, and MFF2 (Multi – Function Flash 2), providing flexibility in card design.
   • Artwork and Printing: We offer the option of customer – specific artwork and printing on both sides of the plastic cards. This can be used for branding purposes or to convey important information. Alternatively, we also provide white plastic cards for a more minimalist look.

In conclusion, HKCARD ELECTRONICS CO., LIMITED offers a comprehensive range of customizable SIM card solutions. Our commitment to quality, flexibility, and innovation makes us the ideal partner for all your SIM card needs, whether for research, testing, or large – scale network operations.
