Open cells SIM card, version 5 (serial 0C 004115 and on wards) looks similar to version 3 but the internal SW is new.<\/p>\r\n

The cards offer 2FF, 3FF and 4FF detachable formats.<\/p>\r\n

The V5 cards support 5V, 3V and 1.8V
We didn’t test yet a 1.8V device (very low power UEs like NB-IoT devices).<\/p>\r\n

It is configured for 3GPP: GSM, WCDMA, LTE with milenage algorithm to perform 3GPP standard subscriber identification. We don’t provide additional features related to Java applets.<\/p>\r\n

Our cards are programmed before shipping with ready to use values.<\/p>\r\n

All our cards are also open for later personalization by our customers.<\/p>\r\n

Some parts of personalization doesn’t require to be standardized: only the operator has to use this interface to change the subscription. So the existing programming tools are not fully compatible with all UICC cards vendors.<\/p>\r\n

We have developed a open source Linux tool: uicc programing<\/a><\/p>\r\n

This SW works with a card reader\/writer to personalize these cards.<\/p>\r\n

We sell raw dialog over a serial interface readers\/writers. These readers are seen as a standard bidirectional serial link over USB in Linux and windows. Any other raw serial interface UICC to USB would be compatible.<\/p>\r\n

\"\"\"\"<\/p>\r\n

Another type of reader is frequently available: PCSC protocol (https:\/\/en.wikipedia.org\/wiki\/PC\/SC). Such readers need drivers. We initiated support of PC\/SC protocol in our SW, using libccid (the most common open source for this). We have little experience yet, it works fine at least with our Gemalto reader.
<\/em><\/p>\r\n

We provide support, only to our customers using our products together: our SW, our cards, our card reader, on Linux.<\/p>\r\n

We supply the cards ready to use (programmed) for OpenAir: telecom values match our hss example database: Open Cells Tuto<\/a>.<\/p>\r\n

Our HSS database also works fine with other OpenAirInterface variants, branches, … as long as the HSS database structure (MySQL schema) is not modified in this specific branch.<\/p>\r\n

Our cards remain open for you to change all values (IMSI, network name, milenage: OPC, Ki, …).\u00a0 Version 4 protects the cyphering files as ‘write only, never read’, so no ADM code management is actually required.<\/p>\r\n

If you need we configure the cards with other values write us: contact@<\/span>open-cells.com<\/span><\/p>\r\n\r\n\r\n","protected":false},"excerpt":{"rendered":"
