What is the cell information in the SMS?

Community is equivalent to the type of radio, in which all kinds of information are sent to your mobile phone in the form of short messages. This has something to do with what service your mobile phone is, such as mobile or Unicom. Every different service provider has a different service number. You can get it with a plus sign, which is completely free.

The cell broadcast number is provided by the operator or checked online!
