FAQ (Schema.org Markup Ready)
Q1 ā What is VoLTE SIM card?
A VoLTE SIM card is an upgraded USIM containing an ISIM application so the phone registers to the IMS core and places HD-voice over LTE/5G.
Q2 ā Do I need a new SIM for VoLTE?
If your existing SIM lacks ISIM or supports only 2G/3G authentication, youāll benefit from an HKCARD VoLTE-ready USIM.
Q3 ā Can I program my own Ki/OPC?
Yes. HKCARD blank programmable USIM cards grant full APDU access for Ki, OP, OPC, AMF, SQN, PLMN, and IMSI editing.
Q4 ā Which security algorithm versions are available?
Standard Milenage, XOR Milenage, XOR only, TUAK (beta).
Q5 ā Minimum order quantity?
10 pcs for stock items; 100 pcs for fully custom branding.
