Featured snippet-friendly FAQ
Q: What is Volte sim cards ?
A: A VoLTE SIM card is a USIM/ISIM-enabled card that supports Voice over LTE by storing IMS credentials and parameters needed for LTE voice calls. It enables HD voice, faster call setup, and simultaneous data and voice on LTE networks.
Q: Do I need a special SIM for VoLTE?
A: Most networks require a USIM with VoLTE/IMS support. If your SIM is old (2G-only), upgrading to a VoLTE-capable USIM/ISIM improves compatibility and call quality.
Q: What’s the difference between USIM and ISIM?
A: USIM authenticates subscribers for 3G/4G/5G data and voice. ISIM adds IMS-specific identities (IMPI/IMPU) and parameters for VoLTE/VoNR. Many test cards include both applications.
Q: What are Milenage and XOR in SIM authentication?
A: They are 3GPP-defined algorithms used for SIM/USIM authentication. Milenage (3GPP TS 35.206) is widely used for 3G/4G/5G; XOR is simpler and common in legacy/lab scenarios. HKCARD provides Milenage Algorithm SIM, XOR Algorithm SIM, and XOR Milenage Algorithm SIM for different testing needs.
Q: Can I order 4G & 5G USIM Programmable SIM Cards for LTE Testing?
A: Yes. HKCARD offers 4G/5G Programmable USIM Test SIM Cards with customizable IMSI/K/OPc, 128K+ memory, and optional ISIM for VoLTE/IMS testing.
Q: Do you have prepaid VoLTE SIM options?
A: We supply VoLTE-capable SIM cards and can support prepaid packaging for operators/MVNOs. For consumer prepaid service, please consult your local operator.
Q: Are test SIMs legal?
A: HKCARD test SIMs are intended for lawful lab, certification, and device testing. They are not tied to any live operator unless explicitly provisioned by your organization. Always comply with local regulations and operator policies.
How to order or request samples
- Send your request with quantity, memory (e.g., 128K), algorithms (Milenage/XOR), form factor, and printing requirements.
