Yes, Truly Roaming mobile data offers a significant upgrade over typical hotel Wi-Fi in places 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, leading to frustrating dropouts during video calls or file uploads. Your personal eSIM provides a private, fast 4G/5G connection that works consistently whether you're in your room, by the pool, or exploring the village, giving you reliable connectivity for focused work.
