Restoring an iPhone without an eSIM, or embedded SIM, is the process of returning the device to its factory settings without the need for an active cellular connection. This can be useful if the eSIM is malfunctioning, the iPhone is being sold or given away, or if the user wants to troubleshoot a software issue.
Restoring an iPhone without an eSIM is a relatively simple process, but it is important to note that all data on the device will be erased. Therefore, it is important to back up any important data before proceeding.
