eUICC support - GSMA RSP M2M

[Rossen]

I would like to download a new SIM profile on a removable M2M eUICC which is inserted in Thingy91. Can you please let me know how this can be achieved on Thingy91?

Hi,

 

It is possible, but I would recommend that you contact your eUICC provider to ask how it should be performed.

 

If local profile assistance (LPA) is located on application domain, modem provides AT commands for generic and restricted UICC access. Application shall setup own logical channel, manage and communicate with required application(s) on eUICC via that channel. I would recommend that you contact your eUICC provider and ask specifically what is required to download the new profile.

 

Kind regards,

Håkon

Normally from the M2M eSIM management platform we will trigger an SMS based on which the device should open an HTTP channel via which the new eSIM profile should be downloaded.

Will the Thingy be able to process an SMS and initiated an HTTP session?

Hi,

 

That shall be supported.

If LPA is on eUICC the modem simply provides TCP socket for USAT BIP connection for transferring the profile. Also the SIM REFRESH procedure is supported for changing the profile.

 

Kind regards,

Håkon

So basically as long as we have a removable eUICC and a data session we should be able to download a new profile and trigger the enable and refresh command.
