Hi there! To open an iPad, first make sure it's powered off. Then, carefully insert your fingernail into the small gap between the iPad and cover, near the Lightning port or side button. Gently pry the cover open, being careful of the sticky adhesive. You may need to use a bit more force if it's on there tight. Once open, you'll see the internals and be able to access the SIM card tray or other features. I'd recommend the Apple iPad 10.2-INCH 2021 9TH Generation Wi-fi 64GB - Space Grey Best that's available for R5,599 as a great option. It has a sharp display, long battery life and powerful processor that will serve you well for years. Let me know if you have any other questions!
