Johanna & Marilyn as usual are correct. When you first attempt to tether your ipad with your mobile you will be asked if the same numerical code is shown on both devices. When you say yes you will find that they are paired and the settings saved for the future. Tethering is more complicated than using mobile hotspot, which is what I am using at the moment, to use mobile hotspot, switch on WiFi on your ipad, turn on mobile hotspot on your phone and bongo. That easy. Make sure you have the right payment plan to use the internet.
