How can I find SSID and phone number on iPhone?

The SSID is the name of the WiFi network. If you are connected to WiFi, it is at Settings > Wifi, and the name is just below the WiFi toggle. You will also see a list of the other SSID's that you can connect to.

The Phone number is at Settings > Phone > My Number.

To find out the phone number on the iPhone.......

Tap Settings

Tap Cellular

Look for My Number

SSID is the “name” of a Wi-Fi network, it has nothing to do with your iPhone.

Your phone number (the number people dial when they want to call you) is in Settings/Apps/Phone

In Settings/Wi-Fi you can see your Wi-Fi address by tapping the i next to the network name; Wi-Fi address and MAC address are synonymous
