Abstract
A method for an eUICC embedded into a machine type communication device to trigger the download of a subscription profile from a first network operator, the eUICC being provisioned with an eUICC identifier and a pre-loaded data set memorizing a range of International Mobile Subscription Identifiers associated to a second network operator by selecting randomly by the eUICC an IMSI number in the range memorized in the pre-loaded data set, sending an attachment request comprising the randomly selected IMSI, receiving in an authentication request message the request for getting the eUICC identifier, as a response, sending to the discovery server a authentication failure message, receiving in an authentication request message a temporary IMSI from the discovery server so that the machine type communication device is able to attach to the first network operator and download the pending subscription profile.
