MH7150 M7 not accepting my eSIM

Hello, just bought a M7 to use a eSIM from Free (working fine on my iPad Pro). Whatever with QR code or manual configuration, the installation of the eSIM is not working.

i would like to use it according to the big data associated to it in different countries.

as mentioned this is fine on my iPad.

Any clue how to make it work ?

The M7 is running the latest firmware.

thanks for your support
