Yes, EastESIM mobile data generally offers a far more consistent and faster connection than hotel Wi-Fi, especially in popular spots like Oia (Santorini) or Mykonos Town. Wi-Fi in many charming cave hotels and Airbnbs can be notoriously slow, congested, and shared among many guests. With your personal EastESIM, you get a private, high-speed 4G/5G connection that works reliably in your room, by the pool, and crucially, as you explore the breathtaking caldera views or vibrant streets. Enjoy uninterrupted connectivity wherever your island adventures take you.
