An LTE-USIM is a USIM card designed for modern mobile networks. In simple terms, a USIM (Universal Subscriber Identity Module) is the secure identity module used in UMTS/3G and also widely required for 4G LTE networks. Compared with older SIM cards, a USIM supports stronger authentication, richer applications, and better control of services.
At HKCARD ELECTRONICS CO.,LIMITED, we supply LTE-USIM products developed for operator and enterprise needs. They are commonly used in WCDMA/TD-SCDMA/CDMA2000 environments and are also designed to be compatible with 4G/3G networks, with backward compatibility to 2G where required.

ToggleWide network compatibility
Depending on the profile and configuration, LTE-USIM cards can be used in:
- 4G LTE / 3G UMTS environments
- Legacy network scenarios such as WCDMA, TD-SCDMA, and CDMA2000
- 2G fallback use cases (backward compatibility)
This is useful for devices that move between coverage areas or require multi-network interoperability during testing and deployment.
Security and data protection
A USIM is not only about network access—it also protects subscriber data and supports secure authentication.
Common security capabilities include:
- 3G Milenage authentication support
- Cryptographic algorithm support such as DES / 3DES / AES (project dependent)
- Stronger access control and data protection design to help protect user data and improve card longevity
Functions commonly requested by operators and solution teams
LTE-USIM cards are often used for value-added and operator-controlled services, for example:
- USAT (USIM Application Toolkit) support
- Smart roaming behavior (profile dependent)
- Multi-IMSI support (project dependent)
- BIP (Bearer Independent Protocol) support for certain toolkit applications
- MMS-related support (profile dependent)
- Remote management functions such as RFM and remote application management (project dependent)
Product series and memory options
To match different device and project needs, LTE-USIM cards can be supplied in different platforms and capacities:
- Platform options: Native and Java series (depending on project requirements)
- Typical memory options: 64K / 128K / 256K (availability depends on card type)
Reliability for long-term deployments
For industrial and operator use, long service life matters. Typical targets include:
- Data retention: 10+ years
- High rewrite endurance: 100,000+ cycles (depending on memory area and usage)
Why USIM is a clear upgrade over traditional SIM
Engineers and operators choose USIM because it offers:
- More flexible services (for example DRM, tracking, pre-provisioned functions—project dependent)
- Better mobility across 2G / 3G / 4G networks
- Support for more complex applications (banking, transportation, retail, and other secure services)
- A stronger authentication model, commonly based on MILENAGE
