A computer-implemented method that includes receiving, by an embedded subscriber identity module (“eSIM”) management platform, a channel request from an eSIM card. In response to the channel request, the platform opens an encrypted data channel and downloads the information to the eSIM card over the encrypted data channel only when the platform has information to download to the eSIM card. Optionally, before the platform receives the channel request, the platform receives a status request from the eSIM card that does not request that the platform open the encrypted data channel, and sends a response to the eSIM card that is positive only when the platform has information to download to the eSIM card, the eSIM card sending the channel request only when the response is positive. The channel request or the status request, when present, originating from the eSIM card and having been triggered by a timer.
