If your data package automatically activated during eSIM installation, it’s likely because your iPhone or iPad is running iOS 16.4 or newer. These devices can automatically activate the data package during installation if they connect to a supported network, without requiring "Data Roaming" to be toggled on.

This streamlined process is designed to simplify setup for users. However, if you’re not ready to use your eSIM yet, make sure to install it only when you're in the correct country and ready to start using data.
