The multi-subscription SIM module includes at least one memory adapted to store at least a first and a second profile associated with a respective first and a second mobile network operator. The memory includes a volatile portion. The operation of storing includes installing or updating profiles by downloading one or more downloaded profiles from a remote host. The management includes selecting one or more enabled profiles including an application to be executed and allocating a partition of the volatile portion of the memory to the one or more enabled profile. ## Claims ### Claim 1 A method for enabling a profile in a multi-subscription SIM module comprising a memory that comprises a first memory partition for an operating system, a second memory partition for an enabled profile, and a third memory partition for a downloaded profile, the third memory partition and the second memory partition having equivalent sizes, the method comprising: connecting, to a base station, using the enabled profile allocated to the second memory partition, the enabled profile being associated with a first mobile network operator; downloading, from a remote host, a downloaded profile, the downloaded profile being associated with a second mobile network operator; accessing, when downloading the downloaded profile, the third memory partition, while maintaining the second memory partition as being non-accessible; allocating the third memory partition to the downloaded profile; and enabling the downloaded profile. ### Claim 2 (depends on 1) The method of claim 1, wherein enabling the downloaded profile comprises swapping the downloaded profile from the third memory partition to the second memory partition. ### Claim 3 (depends on 1) The method of claim 1, wherein enabling the downloaded profile comprises receiving a remote management command, from the remote host, to enable the downloaded profile. ### Claim 4 (depends on 1) The method of claim 1, wherein enabling the downloaded profile comprises enabling the downloaded profile after a power cycle. ### Claim 5 (depends on 1) The method of claim 1, wherein enabling the downloaded profile comprises enabling the downloaded profile after the multi-subscription SIM module is reset. ### Claim 6 (depends on 1) The method of claim 1, further comprising: selecting the enabled profile; and allocating the second memory partition to the enabled profile, while maintaining the third memory partition as being non-accessible. ### Claim 7 (depends on 6) The method of claim 6, wherein allocating the second memory partition to the enabled profile is performed when the multi-subscription SIM module is powered on. ### Claim 8 (depends on 1) The method of claim 1, wherein the memory comprises a volatile memory. ### Claim 9 A method for enabling a profile in a multi-subscription SIM module comprising a memory that stores a first profile and a second profile respectively associated with a first mobile network operator and a second mobile network operator, the method comprising: dividing the memory in a partition for an operating system, partitions for enabled profiles, and a partition for a downloaded profile, the partition for enabled profiles and the partition for a downloaded profile having equivalent sizes; selecting an enabled profile comprising an application to be executed; allocating a first one of the partitions for the enabled profile to the enabled profile, while maintaining the partition for a downloaded profile non-accessible; connecting, to a base station, using the enabled profile allocated to the first one of the partitions for the enabled profile; downloading, from a remote host, a downloaded profile; accessing, when downloading the downloaded profile, the partition for a downloaded profile, while maintaining the partition for enabled profiles non-accessible; allocating the partition for a downloaded profile to the downloaded profile; and enabling the downloaded profile by swapping the downloaded profile from the partition for a downloaded profile to a second one of the partitions for enabled profiles. ### Claim 10 (depends on 9) The method of claim 9, further comprising resetting the multi-subscription SIM module. ### Claim 11 (depends on 10) The method of claim 10, wherein resetting the multi-subscription SIM module comprises resetting the multi-subscription SIM module as a result of a power cycle. ### Claim 12 (depends on 9) The method of claim 9, wherein the multi-subscription SIM module is an eUICC card. ### Claim 13 (depends on 9) The method of claim 9, wherein the second one of the partitions for enabled profiles and the first one of the partitions for enabled profiles are identical. ### Claim 14 (depends on 9) The method of claim 9, wherein the second one of the partitions for enabled profiles is different from the first one of the partitions for enabled profiles. ### Claim 15 (depends on 9) The method of claim 9, wherein selecting the enabled profile comprises selecting only one enabled profile. ### Claim 16 (depends on 9) The method of claim 9, wherein selecting the enabled profile comprises selecting a plurality of enabled profiles. ### Claim 17 A multi-subscription SIM module, comprising: a processor; and a memory comprising a first memory partition for an operating system, a second memory partition for an enabled profile, and a third memory partition for a downloaded profile, the third memory partition and the second memory partition having equivalent sizes, the processor being configured to implement a method comprising: connecting, to a base station, using the enabled profile allocated to the second memory partition, the enabled profile being associated with a first mobile network operator; downloading, from a remote host, a downloaded profile, the downloaded profile being associated with a second mobile network operator; accessing, when downloading the downloaded profile, the third memory partition, while maintaining the second memory partition as being non-accessible; allocating the third memory partition to the downloaded profile; and enabling the downloaded profile by swapping the downloaded profile from the third memory partition to the second memory partition. ### Claim 18 (depends on 17) The multi-subscription SIM module of claim 17, wherein enabling the downloaded profile comprises receiving a remote management command, from the remote host, to enable the downloaded profile. ### Claim 19 (depends on 17) The multi-subscription SIM module of claim 17, wherein enabling the downloaded profile comprises enabling the downloaded profile after a power cycle. ### Claim 20 (depends on 17) The multi-subscription SIM module of claim 17, wherein enabling the downloaded profile comprises enabling the downloaded profile after the multi-subscription SIM module is reset.
