Does iPad 9.7 support eSIM?

No, the iPad 9.7 does not support eSIM.

eSIM is a new technology that allows you to use mobile plans without inserting a physical SIM Card. The iPad 9.7 was designed to work with traditional SIM cards, not eSIM technology.

If you want to use eSIM, consider upgrading to a newer iPad that offers this feature, starting from the 2018 iPad Pro models which include both the 11-inch and 12.9-inch versions. Check out updated list of eSIM-compatible iPads.
