About half a century has passed since the world's first cellular telephone service was launched in 1979.It is said that 5G (5th generation mobile communication system), which is familiar with the Internet and smartphones, will change industries.
Therefore, this time, we will focus on industrial IoT and focus on "sysmo ISIM-SJA2"I'd like to introduce.
This product is a SIM/USIM/ISIM card that allows reprogramming of authentication information.For operators of public or private mobile networks, and for the research community.
However, since the secret ID (key K, OPC) of the original card cannot be determined, the mobile network subscriber cannot duplicate another ID on this card.Please be aware in advance.
Manufacturer: About sysmocom:
Headquartered in Berlin, Germany, sysmocom has contributed to the development of regional cellular networks that do not rely on major vendors since OpenBSC (Open Source Mobile Communications) was launched.A company that strives every day to minimize the development, product and service gaps in the telecommunications market.
What is sysmoISIM
The product is aimed at operators of cellular networks, both large and small.This is because in order to operate a safe and secure cellular network, it is necessary to have important knowledge of SIM/USIM card operations and settings.
sysmoISIM-SJA2 is a reprogrammable SIM, USIM, ISIM card.With multi-cut SIM specification, it supports 2FF (standard SIM), 3FF (micro SIM), 4FF (nano SIM) sizes.
Each card uses a separate ADM key.The default configuration is hacker and developer friendly. AMD keyed cards are field writable and less secure for installing applets.This allows for rapid development cycles.
*If reprogramming is required,Purchase of card with ADM key requiredで す
At our company, sysmoISIM-SJA2 SIM + USIM + ISIM Card,Only with ADM key(10-pack *set of 10 cards).
Major features
- Supports 2G, 3G, 4G, and 5G (authentication is one way)
- Covers 2FF (standard SIM), 3FF (micro SIM), 4FF (nanoSIM) form factors
- Java compatible
- Complete with comprehensive and easy-to-understand user manual
- Emphasis on cellular networks running on the Osmocom protocol stack (*)
■ It does not restrict the use of cards on the network by Osmocom software.However, to receive support, a support contract with sysmocom is required.
