GSMA Generic eUICC test profile

The GSMA test profile is only supported on Eseye's v7 AnyNet+ SIMs. For more information, contact Eseye support.

The GSMA Generic eUICC Test Profile was developed by the GSMA to fulfil the requirements of industry standardised testing defined by the GCF and PTCRB certification bodies, as well as to support devices with non-removable UICCs. It contains the necessary authentication and security data required to perform testing using a test network (system simulator), during production line sampling or during sales demonstrations where there is no need for operator-specific profiles.

The GSMA Generic eUICC Test Profile should be preloaded on SIMs, and is distinct from both the bootstrap (provisioning) profiles and operational (step 2) profiles.

To request a SIM that supports the Generic eUICC Test Profile, contact your Eseye Account Manager.

To switch to and from the Generic eUICC Test Profile using AT commands

Before switching to the test profile, we recommend setting the modem to full functionality mode (AT+CFUN=1).

The following AT command (for generic SIM access) is used to trigger the device to switch to and from the GSMA Generic eUICC Test Profile:

AT+CSIM=<Length>,"<Command>"

Where: 

  • <Length> – is the number of hexadecimal characters contained in the command string.
  • <Command> – is a string of hexadecimal characters that specify the action to take, including the following:
    • 80C2000003E40102 – switches to the Generic eUICC Test Profile.
    • 80C2000003E40103 – switches back from the Generic eUICC Test Profile.

Examples

To switch to the generic test profile, use the following AT command:

AT+CSIM=16,"80C2000003E40102"

To switch back to the previous SIM profile, use the following AT command:

AT+CSIM=16,"80C2000003E40103"
