How long does it take for ICP filing to take effect after receiving SMS? What should I do after the domain name is successfully filed?

The most troublesome thing about ICP filing is that it failed. If you can pass it once, it can be said that it is very smooth. Many friends often just don't fill in the right phone number or need to resubmit it without official seal. This process takes a long time, so it will be more troublesome. The record has been reviewed and the notice has been received. If your website has been built, you can directly resolve the domain name at this time, and the space can be used directly. If your space, domain name and website production are contracted to others, then tell him that he will help you take care of it. If he has finished, he can open it normally the next day, and some of them can be opened immediately. (The longest time for normal DNS resolution to take effect is 24 hours. The explanation of the above questions is because a friend raised the following questions: I received a text message a few days ago saying that my filing was passed, and I would like to ask. Next, what should I do to display the application number at the bottom of my website? I also downloaded it from the website of the Ministry of Industry and Information Technology, but there was no response when I clicked on that certificate to download it. If you understand, please answer. If the certificate has been downloaded, it will show what to do and where to put it. His answer is the above, you don't need to download it, just use it directly.
