What Is a VoLTE SIM Card? 

VoLTE SIM cards (Voice over LTE) are programmable USIM/ISIM cards enabling HD voice, video calls, and messaging over 4G/5G networks without 2G/3G fallback. Unlike standard SIMs, they use:
✔ Milenage Algorithm SIM (3GPP TS 35.206 compliant)
✔ XOR Algorithm SIM (COMP128-1/2/3 legacy support)
✔ IMS credentials (IMPI/IMPU, P-CSCF, SDN-MCC-MNC)

Applications:

• LTE/5G Testing (Anritsu, Keysight, Spirent)
• GCF/PTCRB Certification
• IoT Deployments (Connected cars, smart meters)
• Prepaid VoLTE SIM Cards (OTA top-up enabled)
