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.
