Overview

OmniSIM comes with a GSMA Test Profile (TS.48 - Generic eUICC Test Profile for Device Testing).

The Test profile is disabled by default and is not referenced in CPro or the SM-DP (RSP).

OmniSIM Test profile is aligned with TS.48 v4.x

The Test Profile can be Enabled and Disabled by sending an APDU to the SIM with a CSIM AT Command.

Please note that although KORE has a Test Profile on OmniSIM it is not supported and we assume the user has knowledge of how to use the TS.48 Test Profile with their device.

Enable the Test Profile

The following AT command can be used to send the APDU to instruct the card to switch to the TS.48 Test profile.

Switch to TS.48 Profile

AT+CSIM=16,"80C2000003E40102"

Response

+CSIM: 4,"6103"
OK

The device will lose connectivity and possibly reset. The Test Profile will be enabled

Disable the Test Profile

The following AT command can be used to send the APDU to instruct the card to switch from to the last enabled KORE profile.

Switch back to KORE

AT+CSIM=16,"80C2000003E40103"

Response

+CSIM: 4,"6103"
OK

The device will roll-back to the KORE profile and reconnect to the cellular network.
