SIM cards

Open cells SIM card, version 5 (serial 0C 004115 and on wards) looks similar to version 3 but the internal SW is new.

The cards offer 2FF, 3FF and 4FF detachable formats.

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).

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.

Our cards are programmed before shipping with ready to use values.

All our cards are also open for later personalization by our customers.

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.

We have developed a open source Linux tool: uicc programing

This SW works with a card reader/writer to personalize these cards.

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.

Another type of reader is frequently available: PCSC protocol ( 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.

We provide support, only to our customers using our products together: our SW, our cards, our card reader, on Linux.

We supply the cards ready to use (programmed) for OpenAir: telecom values match our hss example database: Open Cells Tuto.

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.

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

If you need we configure the cards with other values write us:
