Where can I see imess during the power outage?

You can handle blocked iMessage information by setting to view blocked contacts.

1. View blocked contacts through settings: You can unlock the iPhone, find the settings application from the home screen or the application list, and then click Open. In the setting interface, find the information or message option, and then click Enter. In this interface, you can find the list of blocked contacts, and view all hacked phone numbers and iMessage information sent by the other party.

2. Handling intercepted iMessage information: You can view and handle the intercepted iMessage information in the blocked contact list, and you can choose to keep, delete or reply to it. If you choose to reply, you can use the SMS application that comes with the system or a third-party application to send the message.
