System and Method for Multi-SIM Profiles or Embedded SIM

Abstract

Methods and apparatus are provided that select one or more initial subscriber information module (SIM) profile via a mobile device. Multiple SIM profiles including a first SIM profile and a second SIM profile can be stored on a SIM card for the mobile device. The mobile device may attempt to connect to a first network via the first SIM profile. In response to a failure to connect to the first network according to the first SIM profile, the mobile device can access the second SIM profile to connect to a second network according to the second SIM profile. In an embodiment, sequential accessing of SIM profiles stored on the SIM card continues until the mobile device is successfully connected to a network.

         4 . The method of  claim 1 , the method further comprising: selecting, by the mobile device, a second SIM profile for the eSIM of the mobile device, the second SIM profile being associated with a different wireless service provider from a wireless service provider associated with the first SIM profile. 
     
     
         5 . The method of  claim 1 , the method further comprising: selecting, by the mobile device, the first SIM profile from a plurality of SIM profiles stored in the mobile device. 
     
     
         6 . The method of  claim 1 , the method further comprising: selecting, by the mobile device, the first SIM profile in accordance with a downloaded SIM profile from the remote server. 
     
     
         7 . The method of  claim 1 , the method further comprising: decrypting, by the mobile device, the encrypted message in accordance with a server decryption public key and said at least part of the device-specific signature element. 
     
     
         8 . The method of  claim 1 , wherein the step of validating, by the mobile device, the encrypted message comprises: validating, by the mobile device, the encrypted message in accordance with the timestamp and the hardware ID of the mobile device. 
     
     
         9 . A mobile device comprising:
 an embedded subscriber information module (eSIM);   a memory storage comprising instructions; and   one or more processors in communication with the memory, wherein the instructions, when executed by the one or more processors, cause the mobile device to:   transmit a device-specific signature element for activating the eSIM of the mobile device to a remote server, the device-specific signature element comprising a hardware identifier (ID) of the mobile device and a time stamp corresponding to a unique point in time;   receive an encrypted message comprising an encryption of a SIM profile command from the remote server;   validate the encrypted message comprising the encryption of the SIM profile command in accordance with at least part of the device-specific signature element; and   activate, in response to the validation, the eSIM of the mobile device using a first SIM profile in accordance with the SIM profile command.   
     
     
         10 . The mobile device of  claim 9 , wherein the instructions, when executed by the one or more processors, cause the device to transmit the device-specific signature element and to receive the encrypted message using a WiFi connection. 
     
     
         11 . The mobile device of  claim 9 , wherein the instructions, when executed by the one or more processors, cause the device to switch the eSIM from the first SIM profile to a second SIM profile, the second SIM profile being associated with a different wireless service provider from a wireless service provider associated with the first SIM profile. 
     
     
         12 . The mobile device of  claim 9 , wherein the instructions, when executed by the one or more processors, cause the device to select a second SIM profile for the eSIM of the mobile device, the second SIM profile belonging to a different wireless service provider from a wireless service provider of the first SIM profile. 
     
     
         13 . The mobile device of  claim 9 , wherein the instructions, when executed by the one or more processors, cause the device to select the first SIM profile from a plurality of SIM profiles stored in the mobile device. 
     
     
         14 . The mobile device of  claim 9 , wherein the instructions, when executed by the one or more processors, cause the device to select the first SIM profile in accordance with a downloaded SIM profile from the remote server. 
     
     
         15 . The mobile device of  claim 9 , wherein the instructions, when executed by the one or more processors, cause the device to decrypt the encrypted message in accordance with a server decryption public key and said at least part of the device-specific signature element. 
     
     
         16 . The mobile device of  claim 9 , wherein the at least part of the of the device-specific signature element comprises the timestamp and the hardware ID of the mobile device.
