Yes, 100%. Most "all-inclusive" resort Wi-Fi is famously slow, congested with thousands of guests, and only works in the lobby. A personal eSIM gives you a private, fast 4G/5G connection that works everywhere, in your room, by the pool, and, most importantly, on the beach, where hotel Wi-Fi never reaches.
