I have B-L462E-CELL1 development board with ST4SIM200M IC. this board came pre-provisioned with the Truphone profile but I didn't find any way to add a new profile. According to the datasheet eSIm chip supports up to 7 profiles but How can we add and switch between different profiles?

Hi, the ST4SIM-200 is configured with 1GLOBAL (former Truphone) connectivity, and 1GLOBAL is also configured as Subscription Management platform (SM-SR), able to manage remotely the profile on the eSIM.

According the GSMA SGP.02 specification/architecture, the new profile to be downloaded, shall be available on the SM-DP of the operator and the SM-DP integrated with the SM-SR managing the eSIM.

That said, the profile download shall be managed through SM-SR and in that case referring to 1GLOBAL.

The drawback/limitation of this architecture is that the SM-DP of the operator you want to download is not available on 1GLOBAL SM-SR.

Indeed.

@Kobra1991 @ffwali remember that the 'S' in "SIM" stands for "Subscriber" - ie, the one who pays for the service.

The SIM credentials are all about ensuring that the service provider gets paid - so they're not going to allow anyone to just go randomly creating SIMs!

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.
