My iPad does not have an external Sim card

Hello:) If your iPad doesn't include a SIM tray, it's a Wi-Fi-only model that is incapable of connections to cellular data networks. The slot for the SIM card in the iPad is on the side, toward the top of the iPad. The top of the iPad is the side with the camera.
