Frequently Asked Questions )
| # | Question | Answer |
|---|---|---|
| 1 | What is a blank SIM card? | A blank SIM contains no subscriber data, allowing the user to program IMSI, Ki, OPc, and other fields using a SIM programmer. |
| 2 | How do I program a blank SIM card? | Use a SIM Card Programmer together with HKCARD’s SIM Programming Software; load the desired credential file and write it to the card. |
| 3 | Are your 5G USIMs 3GPP Release 16 compliant? | Yes. All 5G USIM Cards are tested against Release 16 and support both SA (stand‑alone) and NSA (non‑standalone) architectures. |
| 4 | Can you provide white‑label MVNO SIMs with custom packaging? | Absolutely. We produce Blank White‑Label MVNO SIM Cards in 2FF, 3FF, and 4FF formats with any branding, printing, and packaging you require. |
| 5 | What is the difference between a dummy SIM and a blank SIM? | A dummy SIM is a non‑functional placeholder used only for mechanical testing. A blank SIM is a functional smart card that can be fully programmed for network use. |
| 6 | Do you support bulk provisioning for thousands of SIMs? | Yes. Our SIM Personalize Tools and SIM Card Programmer can handle high‑volume write cycles, and we provide SIM wholesale pricing for large orders. |
| 7 | Are your cards compatible with Sysmocom tools? | All of our programmable cards are Sysmocom compatible, including SysmoISIM‑SJA5 and SysmoISIM‑SJA2 models. |
| 8 | What is a writable IMSI SIM? | A writable IMSI SIM allows the IMSI value to be changed multiple times, useful for testing roaming scenarios or private network migration. |
| 9 | Do you offer NFC‑enabled SIMs? | Yes, we supply NFC‑enabled programmable SIMs and SWP SIM Cards for secure NFC applications. |
| 10 | How can I get a price quote for 64K or 128K SIM cards? | Contact our sales team (link below) with the quantity and required memory size; we will return a competitive quote within 24 hours. |
