I would like to buy insurance for my iPad. Like apple care

AppleCare can be purchased along with your iPad, or within 60-days after initial purchase. More details about purchasing AppleCare for your iPad can be found here:

Buy an AppleCare plan - Apple Support

After 60-days, or if your iPad is not eligible, you might find a third-party insurance product elsewhere. Your domestic/home insurance policy may also cover your portable devices - or may have a policy extension that your can purchase.
