You will need to obtain a nanoSIM from your chosen Cellular provider - who will supply a SIM when you have arranged a cellular plan for your iPad.
Set up cellular data service on your Wi-Fi + Cellular model iPad - Apple Support
Newer models of iPad also support eSIM - this being a built-in electronic alternative to a physical SIM card.
