What is a VoLTE SIM Card?
A VoLTE SIM card (Voice over LTE) is a programmable USIM/ISIM card enabling HD voice/video calls over 4G/5G networks without 2G/3G fallback. Key features include:
- ISIM Application: Stores IMS credentials (IMPI/IMPU, P-CSCF).
- Milenage/XOR Algorithms: 3GPP-compliant authentication.
- 128K EEPROM: Supports multiple profiles and OTA updates.
As a leading VoLTE SIM cards manufacturer/provider/supplier, HKCARD offers volte sim karte, 4G VoLTE programm SIM Karte ISIM USIM Karte 128k, and volte sim cards prepaid solutions for global telecom operators, labs, and IoT enterprises.
“A VoLTE SIM card is a programmable USIM enabling HD calls over 4G/5G. HKCARD supplies VoLTE ISIM cards, Milenage/XOR algorithm SIMs, and 4G 5G VoLTE test SIM cards with 24-hour shipping.”
A VoLTE SIM card is an advanced USIM (Universal Subscriber Identity Module) that supports Voice over LTE technology, enabling high-definition voice calls over 4G LTE networks. Unlike traditional SIM cards, VoLTE SIM cards incorporate ISIM (IP Multimedia Services Identity Module) functionality, allowing devices to register with the IP Multimedia Subsystem (IMS) core network.
