Yes, on eligible versions.
The UK specification excludes eSIM on the standard Phone (4a). In Japan, IIJmio tested voice eSIM on the local version. Confirm where the phone was sold.

Match the model number
Open Settings → About phone (or About device). Match the number and original sales region against the manufacturer’s specifications.
Find the eSIM settings
Look for EID in your device information. An IMEI alone does not prove eSIM support. Check Settings → SIMs or Mobile network and the option to add or download an eSIM; menu names vary.
Confirm carrier unlocking
Ask the carrier that originally sold the device to confirm it is network-unlocked and can use another provider’s eSIM. Android does not have one lock-status menu shared by every brand. Your provider still needs to support your device.
