2. What Exactly Is a “Half Card” Combo USIM?
The term Half Card refers to a SIM card whose physical outer dimensions match a standard 2FF plug-in SIM (roughly 25mm x 15mm), but with precision-cut breakouts that allow the user to easily detach either a 3FF or a 4FF SIM from the same piece. This means:
- No adapters required
- One SKU covers every phone, tablet, dongle, router, and IoT module
- Reduced packaging waste and simplified logistics
The 128K memory provides ample space for phonebook entries, SMS storage, and robust network parameter files – more than sufficient for traditional telecom services and basic IoT connectivity.
3. Why Choose HKCARD’s 500K USIM Combo Batch?
✅ 3.1 Massive Scalability, Consistent Quality
With 500,000 pieces ready for deployment, HKCARD can support large-scale operator rollouts, SIM replacement campaigns, or multi-regional distribution without production bottlenecks. Every chip is tested under stringent ISO/IEC 7816 and ETSI standards.
✅ 3.2 True “3-in-1” Convenience
End users simply pop out the required size. There is no need for call center staff to ask “Which SIM size does your phone use?” – a significant reduction in support costs and consumer frustration.
✅ 3.3 Branding & Personalization Options
HKCARD offers full customization: operator logo printing, unique ICCID/SIM serial number ranges, PIN/PUK personalization, and even customized packaging. The half-card surface provides a generous area for branding and legal disclaimers.
✅ 3.4 128K Software Flexibility
Beyond standard USIM functionality, the 128K profile can house operator-specific applets, roaming lists, and enhanced security algorithms. HKCARD’s pre-personalization team can load custom profiles before shipment.
