The method may be performed in a migration entity and comprises: receiving, from the source device, a confirmation of a first profile associated with the subscription having been deleted in the source device, securing a second profile associated with the subscription to be provisioned onto the eUICC of the destination device, wherein at least one piece of subscription information is the same for the first and second profiles, and providing an activation code for use in migration of the subscription to the destination device. A method in a source device, migration entity, source device, computer programs and computer program products are also provided. ## Claims ### Claim 1 A method enabling migration of a subscription from a source device to a destination device, the method being performed in a migration entity and comprising: receiving, from the source device, a confirmation of a first profile associated with the subscription having been deleted in the source device, securing a second profile associated with the subscription to be provisioned onto the eUICC of the destination device, wherein at least one piece of subscription information is the same for the first and second profiles, and providing an activation code for use in migration of the subscription to the destination device. ### Claim 2 (depends on 1) The method as claimed in claim 1, comprising, prior to the securing, receiving, from the source device, an identification, EID, of an embedded universal integrated circuit card, eUICC, of the destination device. ### Claim 3 (depends on 1) The method as claimed in claim 1, wherein the migration entity comprises a network entity and the step of securing a second profile for the destination device comprises sending, to a Subscription Manager Data Preparation, SM-DP+, entity, a request for updating the first profile related to the subscription and receiving in response a confirmation of a second profile having been created. ### Claim 4 (canceled) ### Claim 5 (depends on 1) The method as claimed in claim 1, wherein the migration entity comprises a Subscription Manager Data Preparation, SM-DP+, entity and the step of securing a second profile for the destination device comprises creating a profile package with at least some profile data being the same as for the first profile of the source device. ### Claim 6 (canceled) ### Claim 7 (canceled) ### Claim 8 (depends on 1) A computer program product comprising a computer readable media storing a computer program for a migration entity for migration of a subscription, the computer program when executed on at least one processor on the migration entity causes the migration entity to perform the method according to claim 1. ### Claim 9 A migration entity enabling migration of a subscription from a source device to a destination device, the migration entity being configured to: receive, from the source device, a confirmation of a first profile associated with the subscription having been deleted in the source device, secure a second profile associated with the subscription to be provisioned onto the eUICC of the destination device, wherein at least one piece of subscription information is the same for the first and second profiles, and provide an activation code for use in migration of the subscription to the destination device. ### Claim 10 (depends on 9) The migration entity as claimed in claim 9, configured to, prior to the securing, receive, from the source device, an identification, EID, of an embedded universal integrated circuit card, eUICC, of the destination device. ### Claim 11 (depends on 9) The migration entity as claimed in claim 9, wherein the migration entity comprises a network entity and is configured to secure a second profile for the destination device by sending, to a Subscription Manager Data Preparation, SM-DP+, entity, a request for updating the first profile related to the subscription and receiving in response a confirmation of a second profile having been created. ### Claim 12 (depends on 11) The migration entity as claimed in claim 11, wherein the request for updating comprises identification of the first profile and indication on any parameter changes. ### Claim 13 (depends on 9) The migration entity as claimed in claim 9, wherein the migration entity comprises a Subscription Manager Data Preparation, SM-DP+, entity and is configured to secure a second profile for the destination device by creating a profile package with at least some profile data being the same as for the first profile of the source device. ### Claim 14 (depends on 9) The migration entity as claimed in claim 9, wherein the first and second profiles have as common subscription information one of an International mobile subscriber identity, IMSI, and Mobile Station International Subscriber Directory Number, MSISDN, and wherein an authentication key associated in the destination device with the IMSI is different than a corresponding authentication key associated in the source device with the IMSI. ### Claim 15 A method enabling migration of a subscription to a destination device, the method being performed in a source device and comprising: sending, to a migration entity, a confirmation of a first profile associated with the subscription having been deleted in the source device, and sending, to the migration entity, one of: an identification, EID, of an embedded universal integrated circuit card, eUICC, of the destination device and indication about the EID of the eUICC of the destination device being unknown. ### Claim 16 (depends on 15) The method as claimed in claim 15, comprising receiving, from the migration entity an activation code for use in downloading the second profile to the destination device. ### Claim 17 (depends on 15) The method as claimed in claim 15, wherein the sending, to a migration entity, the confirmation of a first profile associated with the subscription having been deleted in the source device, comprises signing the confirmation by a certificate for the eUICC and including in the confirmation an identity identifying the first profile. ### Claim 18 (canceled) ### Claim 19 (canceled) ### Claim 20 (canceled) ### Claim 21 (depends on 15) A computer program product comprising a computer readable medium storing a computer program that when executed by a processor performs the method of claim 15. ### Claim 22 A source device enabling migration of a subscription to a destination device, the source device being configured to: send, to a migration entity, a confirmation of a first profile associated with the subscription having been deleted in the source device, and send, to the migration entity one of: an identification, EID, of an embedded universal integrated circuit card, eUICC, of the destination device and indication about the EID of the eUICC of the destination device being unknown. ### Claim 23 (depends on 22) The source device as claimed in claim 22, configured to receive, from the migration entity an activation code for use in downloading the second profile to the destination device. ### Claim 24 (depends on 22) The source device as claimed in claim 22, configured to send, to a migration entity, the confirmation of a first profile associated with the subscription having been deleted in the source device, by signing the confirmation by a certificate for the eUICC and including in the confirmation an identity identifying the first profile. ### Claim 25 (depends on 22) The source device as claimed in claim 22, configured to, prior to sending a confirmation of the first profile being deleted, set up a secure session with the migration entity, and to use secure session keys in further communication with the migration entity. ### Claim 26 (depends on 22) The source device as claimed in claim 22, configured to send the activation code to the destination device.
