Title: A METHOD FOR AN EUICC EMBEDDED INTO A MACHINE TYPE COMMUNICATION DEVICE TO TRIGGER THE DOWNLOAD OF A SUBSCRIPTION PROFILE
Abstract:
The invention related to a method for an eUICC embedded into a machine type communication device (300) to trigger the download of a subscription profile from a first network operator (MNO1), the eUICC being provisioned with an eUICC identifier (EID) and a pre-loaded data set memorizing a range of International Mobile Subscription Identifiers (IMSI) associated to a second network operator (MNO2), the method comprising the steps of: selecting randomly by the eUICC an IMSI number in the range memorized in the pre- loaded data set; sending an attachment request (310) comprising the randomly selected IMSI (R-IMSI); receiving in an authentication request message (313) the request for getting the eUICC identifier (EID); as a response, sending to the discovery server (302) a authentication failure message (314); receiving in an authentication request message (317) a temporary IMSI (t-IMSI) from the discovery server (302) so that the machine type communication device is able to attach to the first network operator (MNO1) and download the pending subscription profile.
