Looking for dependable test SIMs for lab, field, or certification work? HKCARD ELECTRONICS CO.,LIMITED is a reliable supplier in the mobile phone test card industry with 10+ years of experience. We design and manufacture programmable test SIM/USIM/eUICC cards and profiles that help device makers, operators, certification labs, and IoT developers validate connectivity, authentication, IMS/VoLTE, security, and NFC—quickly and consistently.

What is a test SIM card?
A test SIM (USIM/eSIM) is a programmable card or profile used to simulate network credentials and scenarios so engineers can verify LTE/5G attach, IMS/VoLTE/VoNR services, roaming, security algorithms, and application behavior without risking live production data.

Why HKCARD

• Proven reliability: Over a decade focused on mobile testing SIMs for 2G/3G/4G/5G, IMS, NFC, and IoT
• Flexible customization: IMSI/Ki/OPC/ISDN/SPN/PLMN lists, APN/IMS parameters, file system (EF/DF) contents, STK/USAT
• Broad standards coverage: Built around 3GPP specs typically used in device and network test flows (e.g., 31.102/31.121/33.102/24.301), plus SA/NSA 5G scenarios for USIM/ISIM
• Interop in the lab: Designed to work with common callboxes and analyzers used across R&D and certification test setups
• Global support: Serving OEM/ODM, operators, test labs, and solution integrators worldwide

FAQs 

• What’s the difference between a test SIM and a commercial SIM?
  Test SIMs are programmable and designed for lab/certification use; they allow custom IMSI/keys/parameters and predictable behavior, unlike consumer SIMs tied to live networks.

• Can I use one test SIM for 4G and 5G?
  Yes—our 4G 5G VoLTE test SIM cards and 5G SA/NSA USIM test card options cover LTE, NR SA/NSA, and IMS/VoLTE/VoNR scenarios.

• Do you support eSIM testing?
  Yes—eSIM / eUICC test profile options enable profile download, activation, switching, and policy rules testing.

• Do you offer Multi‑IMSI?
  Yes—Multi-IMSI Test SIM Cards let you switch IMSI profiles for multi-operator and roaming tests.

• Can you help with VoLTE/IMS?
  Yes—we provide VoLTE Testing SIM Cards and parameters for IMS registration, SIP, emergency calling, and supplementary services testing.
