Abstract: This Application sets forth techniques for provisioning and activating electronic subscriber identity modules (eSIMs) for mobile wireless devices. An eSIM is reserved during a sales order process and later activated during device activation after receipt by a user. An option for eSIM installation in place of (or in addition to) physical SIM installation is provided when purchasing the mobile wireless device. The reserved eSIM can replace a previous SIM/eSIM or be a new eSIM. During device activation, installation and activation of the eSIM occurs. Activation of the eSIM can occur before or after deactivation of a transferred SIM/eSIM. The mobile wireless device accounts for propagation delay of eSIM activation through MNO servers by disabling and re-enabling the eSIM until initial attachment to an MNO cellular wireless network succeeds or a maximum number of retry attempts is reached.

Abstract: A server of a wireless operator creates a roaming list based on a user's roaming plan and sends the roaming list to the user's wireless device. The roaming list includes a list of public land mobile networks (PLMNs). When the user travels away from their home wireless network to another geographic area, the wireless device scans based on the roaming list for radio signals. The roaming list contributes to user satisfaction because timely attachment to a radio network while away from home occurs efficiently since the wireless operator creates the roaming list based on both i) roaming agreements that the wireless operator is a party to with other wireless operators, ii) the user's roaming plan, iii) the radio access technology (RAT) capabilities of the wireless device and iv) the RAT capabilities of other wireless operators in particular geographic regions.

Abstract: This application sets forth techniques for provisioning electronic subscriber identity modules (eSIMs) to mobile wireless devices that do not include functional bootstrap provisioning profiles to obtain access to a cellular wireless network. Connectivity to a cellular wireless network can be allowed for provisioning one or more eSIMs to a mobile wireless device using hardware device identifiers for authentication and a limited purpose provisioning connection when the cellular wireless network supports provisioning connections without the use of a provisioning profile for access.

Abstract: This Application sets forth techniques for provisioning and activating an electronic subscriber identity module (eSIM) as a primary SIM for a mobile wireless device that includes a limited functionality physical SIM (pSIM) associated with a particular mobile network operator (MNO) and installed in the mobile wireless device at a time of manufacture. An eSIM associated with the particular MNO is reserved during a sales order process and later activated during device activation after receipt by a user using a secure over-the-air (OTA) cellular connection enabled by the limited functionality pSIM, when a non-cellular connection or other Internet accessible connection is available. Dual SIM device configuration processes can be suppressed during activation of the eSIM. After successful attachment of the mobile wireless device to a cellular wireless network of the particular MNO using credentials of the eSIM, the limited functionality pSIM is disabled.

Abstract: Techniques to manage updates for eSIMs of a secondary wireless device are disclosed. Responsive to a user input, expiration of a timer, receipt of a message from an associated primary wireless device, processing circuitry of the secondary wireless device commands an eUICC to update an eSIM. A secure data connection is established between the eUICC and a network provisioning server, either directly from the secondary wireless device to a cellular wireless network or relayed indirectly via the primary wireless device. The eUICC and the network provisioning server exchange messages in accordance with a BIP process to update the eSIM. The eUICC provides a status to the processing circuitry indicating success or failure for the eSIM update. Upon success, a portion of the secondary wireless device may be placed in a reduced power state. Upon failure, the eSIM update process may repeat up to a maximum number of retries.
