At HKCARD ELECTRONICS CO.,LIMITED, we supply blank programmable SIM cards for engineers, test labs, and developers who need a card they can reuse. These cards are designed to be rewritable, so you can program a profile, run your tests, then erase or update the data and program again.
They are commonly used in telecom testing, device validation, and SIM application development—where you don’t want to consume a new card every time you change one parameter.
What can be programmed (typical items)
Depending on your programming tools and permissions, these blank SIM cards can be written with items such as:
- ICCID
- IMSI
- KI
- OPC / OP
- PIN / PUK
- ADM
- GSM-related data (project-dependent)
Important: these are blank test cards. They do not come with an active operator subscription.
SIM size: 3-in-1 (punch-down format)
Each card is perforated so you can use the size you need:
- 2FF (Standard / Mini SIM)
- 3FF (Micro SIM)
- 4FF (Nano SIM)
This makes the same card usable across phones, routers, and different modem platforms.
Who it’s for
These cards are intended for:
- Telecom operator labs and private network testing
- Device manufacturers and module QA teams
- R&D engineers who need repeatable programming cycles
If you tell us your test goal and the reader/writer model you use, HKCARD ELECTRONICS CO.,LIMITED can recommend the right blank SIM option for your workflow.
