As it is compliant with the ETSI, 3GPP and 3GPP2, the ST4SIM-200M can easily be integrated into any OTA

platform compliant with relevant standards. STMicroelectronics cards are field-proven to be interoperable with the

mainstream OTA platforms commonly chosen by mobile network operators.

Memory management

The OTA mechanism includes the support of 3G UICC administrative commands as specified by ETSI TS 102

222.

These commands are integrated by a powerful dynamic memory management that allows complete smart

memory defragmentation.

Dynamic memory management provides:

•

Common space for files, packages, applets and objects

•

Memory recovery on deletion operations

•

Total free memory available in the select MF response.

The OTA mechanism is designed to allow a very fast and silent memory recovery, absolutely safe for the end user

data.

The ST4SIM-200M is capable of enhancing intrinsic Flash memory cells for files requiring intense update and

high reliability.

Memory quota mechanism based on the GlobalPlatform Amendment C (CGM) is supported. The mechanism can

be disabled at card configuration.

Volatile memory management is based on an STMicroelectronics patented mechanism that optimizes the

available resources for the enabled profile while guaranteeing resources for the downloading profile and the

disabled profiles.
