FAQ: Your Questions Answered (Google Featured Snippet Optimized)
Q: What is a VoLTE SIM card?
A: A VoLTE SIM card is an advanced USIM with an embedded ISIM application, enabling HD-voice calls over 4G LTE and 5G data networks. Unlike traditional SIMs, it supports IP Multimedia Subsystem (IMS) protocols for crystal-clear voice quality and reduced latency.
Q: Do I need a special SIM for VoLTE?
A: Yes. Legacy 2G/3G SIMs lack ISIM support, causing incompatibility with VoLTE networks. HKCARD’s programmable USIM cards are pre-configured for VoLTE activation, ensuring seamless upgrades.
Q: Can HKCARD SIMs be reprogrammed for different networks?
A: Absolutely. Our blank programmable USIM cards allow unlimited rewrites of Ki, OPC, IMSI, and PLMN values via APDU commands, making them ideal for multi-carrier testing.
Q: Which algorithms do your security SIMs support?
A: We offer Milenage (3GPP-standard), XOR Milenage (hybrid efficiency), and XOR-only variants for resource-limited devices like IoT sensors.
Q: What’s the minimum order for custom SIMs?
A: Stock items start at 10 pcs; custom-branded SIMs require 100 pcs MOQ, with logos, profiles, and packaging tailored to your brand.
