eSIM for Greece — Instant 4G/5G Data Plans

Greece's mobile network is served by three main operators: Cosmote, Vodafone Greece, and Wind Hellas. 4G LTE coverage is comprehensive across Athens, Thessaloniki, and all major mainland cities, with reliable connectivity along main highway corridors and ferry port areas. Popular islands including Mykonos, Santorini, Corfu, Rhodes, Crete, and Zakynthos have coverage in their main towns and resort areas, though more remote beaches, mountain interiors, and smaller uninhabited islands may have weaker signal. The Peloponnese, Epirus mountains, and rural areas of northern Greece have generally reliable coverage in populated zones with some variation in terrain. MobiSIM connects through supported Greek networks to deliver reliable data across Greece's main cities, islands, and tourist destinations.

Install your MobiSIM eSIM before landing at Athens International Airport or your arrival island airport so you are connected from the start. Greece's ferry network connects hundreds of islands and having live data for Ferryscanner, OpenSeas, and port schedules makes island hopping significantly easier. Keep your home SIM active for calls while MobiSIM handles your data. Download offline maps for Santorini's caldera paths, Crete's Samaria Gorge, and any remote island or mountain hiking areas before departing main towns, as clifftop and gorge terrain can have inconsistent signal. If you are sailing or chartering a yacht around the Cyclades, Dodecanese, or Ionian islands, save marina contacts, weather apps, and navigation details offline as offshore and anchorage signal varies considerably between locations.
