Quick answer
Yes. All Samsung Galaxy S25 models — S25, S25+, and S25 Ultra — support eSIM. All variants ship with a nano-SIM slot plus eSIM, enabling Dual SIM (physical SIM for home calls, eSIM for travel data). The S25 series runs One UI 7 on Android 15 with an improved SIM manager interface. Carrier-locked S25 models may restrict third-party eSIM profiles — factory-unlocked or SIM-free models have no such restriction.
