Company Overview

HKCARD ELECTRONICS CO.,LIMITED stands as a premier manufacturer and global supplier specializing in programmable telecommunications testing solutions and MIFARE card technology. With over a decade of experience serving telecommunications laboratories, mobile network operators (MNOs), mobile virtual network operators (MVNOs), device manufacturers, and certification bodies worldwide, HKCARD has established itself as the go-to source for Blank Programmable USIM Cards, 4G & 5G USIM Programmable SIM Cards for LTE Testing, and comprehensive MIFARE card solutions.

What is VoLTE SIM Cards? 

VoLTE SIM cards are specialized USIM/ISIM cards that enable Voice over LTE technology, allowing voice calls to be made over 4G LTE networks rather than falling back to 3G or 2G. These cards store IMS (IP Multimedia Subsystem) credentials and authentication parameters necessary for HD voice calling, faster call setup times, and simultaneous voice and data services on LTE networks.

Key Features of VoLTE SIM Cards:

  • IMS Authentication: Stores IMPI/IMPU credentials
  • HD Voice Quality: Supports wideband audio codecs
  • Faster Call Setup: Reduces connection time by 50%
  • Simultaneous Services: Voice and data work simultaneously
  • Enhanced Security: Advanced encryption algorithms
