What is sm-dp address?

The SM-DP (Subscription Manager Data Preparation) address is an essential component of a mobile network infrastructure, specifically related to the provisioning and management of eSIM (embedded SIM) technology.

An eSIM is a small chip embedded in a device that can be remotely activated and configured to support cellular services, eliminating the need for physical SIM cards. The SM-DP address plays a vital role in the eSIM provisioning process.

When a device with an eSIM is activated, it needs to connect to an SM-DP server to obtain the necessary subscription data for network access. The SM-DP address serves as the server's location, allowing the device to establish a secure connection and retrieve the required information.

The SM-DP server handles various tasks, including downloading and securely storing the operator's profile on the eSIM, managing multiple profiles (if applicable), and handling subscription changes or updates. This server can be operated by a mobile network operator or an authorized third party.

It is important to note that the SM-DP address is specific to each mobile network operator or service provider. Users generally receive the SM-DP address along with the necessary instructions and credentials from their service provider during the eSIM activation process.

Overall, the SM-DP address is a crucial element in the eSIM ecosystem, enabling devices to securely obtain and manage subscription data, offering flexibility and convenience for users in managing their mobile network connectivity.
