What Are VoLTE SIM Cards?
VoLTE (Voice over LTE) SIM cards are specialized USIM/ISIM cards that enable HD voice calls, video calling, and SMS over 4G/5G networks without falling back to 2G/3G. Unlike traditional SIMs, VoLTE SIMs support IMS (IP Multimedia Subsystem) authentication and require Milenage or XOR algorithm encryption for secure network registration.
Key Features of VoLTE SIM Cards:
✔ ISIM Application – Stores IMS credentials (IMPI, IMPU, P-CSCF)
✔ Milenage & XOR Algorithm Support – Ensures secure authentication
✔ 128K EEPROM – High storage for multiple profiles
✔ 4G/5G Compatibility – Works with LTE, VoLTE, and 5G NR networks
✔ Programmable via PC/SC Readers – Customizable IMSI, Ki, OPC, and ICCID
