1. A method, comprising:
detecting a hotspot of a primary terminal having a network connection;
establishing, based on detecting the hotspot, a local connection between the primary terminal and a companion terminal not having the network connection;
generating secure connectivity information comprising address information of the companion terminal and security information of the companion terminal;
indicating, to the primary terminal, the secure connectivity information;
receiving a secure connectivity request from the primary terminal using a first secure session established between the primary terminal and the companion terminal;
sending a secure connectivity response to the primary terminal after receiving the secure connectivity request;
establishing a second secure connectivity session between the companion terminal and the primary terminal using the secure connectivity information;
receiving, through the local connection and using the second secure session between the companion terminal and the primary terminal, an operation instruction for an Embedded Universal Integrated Circuit Card (eUICC) of the companion terminal; and
deleting a profile from the eUICC of the companion terminal or downloading the profile to the eUICC of the companion terminal.
