Samsung A24 4G has a dedicated SD card slot and has Single and Dual Nano sim card variants. However, the device does not support eSim.
The Galaxy A24 has a memory card space that supports up to 1TB SD card to expand the 128GB internal storage the device has.
As for eSim, this is one of those features that is still available only on their flagship or expensive devices.
Hopefully, like the under-display fingerprint, IP ratings, and high refresh rate that used to be flagship-only features that have now made their way to the mid-range device, eSim will do the same in the coming years.
In the meantime, you will have to manage the Nano sim card the device has.
