At present, the management of the internet of things equipment on the profile in the eUICC card can be actively initiated by a server side (smds) to manage the profile in the eUICC card, and operations such as deleting, issuing and enabling are performed. For example:

(1) the method comprises the steps that an eUICC card in the Internet of things equipment actively reports the online state to a server through short messages, and after the server receives the online state of the eUICC card, the server informs an SMDP + to send prepared profile to the eUICC card through a plurality of short messages;
