`+C*REG:` may be received as AT read command answer or unsolicited notification. Their syntax differs, and even the overall parameter count varies depending on what `<n>` is used in the `AT+CEREG=` write command. To handle all cases properly, check the parameter count and the presence of the `<tac>` parameter (which is a string and thus begins with `"`) to figure out what is the position of `<stat>`.
