It comes with a protective cover, I would also recommend armoured glass, as it is a large and heavy mobile. The case doesn't have RFID, I would have noticed that.
No, this model does not support eSIM. According to official information, the Redmi 15 5G does not support eSIM technology and only uses physical SIM cards in Nano format.
A charging plug with USB A or if you still have a charging cable with 2x USB C, one with a USB C connection with a power of 5 - 33 W.
(see device specifications)
The device has a standard 3.5 mm audio jack, so you can use headphones with a traditional connector without the need for adapters. This feature is confirmed for the model with 5G support.
