description A temporary EID (TEID) is generated based on an indicator of a hash algorithm, a nonce, and a hash generated using the hash algorithm. The hash is generated based on the indicator, nonce, and EID of a mobile device. The TEID is sent to the mobile network operator to identify the mobile device in lieu of using the device's EID. The TEID is stored in a data store and an eSIM profile for the mobile device is associated the TEID. The mobile device sends to an eSIM server the device's EID over a secure communications channel. The eSIM server generates a hash using the indicator and nonce contained in the stored TEID and the EID of the mobile device. The eSIM server verifies that the generated hash matches the hash contained in the TEID stored in the data store. If the hash matches, the eSIM server sends, to the mobile device, subscription credentials for accessing the mobile network in accordance with the data plan.
