What Are VoLTE SIM Cards?
:What is a VoLTE SIM Card? Definition & Applications
A VoLTE SIM card (Voice over LTE) is a programmable USIM with IMS (IP Multimedia Subsystem) support, enabling HD voice/video calls over 4G/5G networks. Unlike traditional SIMs, it uses:
- Milenage Algorithm SIM (3GPP TS 35.206 compliant)
- XOR Algorithm SIM (COMP128-1/2/3 compatible)
- ISIM Application (IMPI/IMPU, P-CSCF credentials)
Key Applications:
- 4G/5G LTE Testing (e.g., Anritsu/Keysight test equipment)
- VoLTE Certification (GCF/PTCRB, Google VTS)
- IoT/M2M Deployments (Connected cars, smart meters)
- Prepaid VoLTE SIM Cards (OTA top-up ready)
“A VoLTE SIM card is a programmable USIM with IMS support for HD voice over 4G/5G. It requires Milenage/XOR algorithms and is used for LTE testing, certification, and IoT applications. As a VoLTE SIM cards manufacturer/provider/supplier, HKCARD offers 128K ISIM/USIM cards with 24-hour shipping.”
