Does iPad mini series support eSIM?

No, the iPad Wi-Fi series does not support eSIM, including iPad mini 2, iPad mini 3, iPad mini 4, iPad mini Wi-Fi, iPad mini Wi-Fi + Cellular.

eSIM is a new technology that allows you to use mobile plans without inserting a physical SIM Card. The iPad mini series was designed to work with traditional SIM cards, not eSIM technology. If you want to use eSIM, you have two options:

1. Use a special SIM card adapter: You can purchase a special adapter that allows your device to handle eSIM profiles. This adapter can be used to enable eSIM functionality on devices that do not have native support for it.
2. Upgrade to a newer iPad model: If you want built-in eSIM support, you will need to consider upgrading to a newer iPad that offers this feature. Starting from the the 2018 iPad Pro models. This includes both the 11-inch and 12.9-inch versions. Check out eSIM-compatible iPads here.

Note: Remember that eSIM availability may vary depending on your location and the devices offered by your mobile service provider.
