Adding and switching eSIM profile

Dear Nikint,

Can you explain how you did this? I have the same questions, but looking at the +CSIM and +CRSM commands I can't see how I can change and/or add profiles. I already read the APDU protocol (www.etsi.org/.../ts_102221v170100p.pdf), but the problem remains.

Best Regards,

Nuno

Hi Øyvind,

Thank you for the reply!!

Concept of eSIM profile switch is cleared from your reply. We will come up with other queries in near future if any.

Thank you.

Hello,

[quote user=""] How to switch profiles on eSIM using AT commands? Need detailed procedure.[/quote]

The modem can handle the switching automatically. We would recommend reading our AT commands documentation on UICC access commands, specifically +CSIM and +CRSM commands which are standard. Your SIM card provider should be able to provide the procedure to you.

On the application side, there is nothing to be done. This is handled automatically by the SIM card provider's system, and the SIM card. The modem provides the necessary communication channels. Have a look at the GSMA eSIM Whitepaper - The what and how of Remote SIM Provisioning

[quote user=""] Does switching and adding new profile requires any additional GPIO pins? (Apart from basic eSIM connections)[/quote]

No, there are no additional GPIO pins needed.

Kind regards,
