"No Service" is Shown:

Loot on the top-left cornet of your screen. Apparently you have no service.. So if this is a new iPhone, then you need a SIM card in it to get service, and Wi-Fi. As for troubleshooting this, contact you carrier, as they are the one who provide you with the service of Cellular.
