Important cities in Greece
Athens · City guide
Athens spreads its ancient sites across a busy modern city, and an Athens eSIM ties the two together. Navigate from the Acropolis and the Plaka lanes to the buzzing squares of Monastiraki, book metro or ride-hailing across town, and check ferry times at Piraeus if the islands are calling. With data running, you can pivot between marble ruins and rooftop bars without ever losing your bearings.
Athens eSIM — online before you land →Thessaloniki · City guide
Greece's vibrant second city rewards aimless wandering along its waterfront, and a data plan for Thessaloniki keeps you oriented while you do it. Stroll from the White Tower along the seafront promenade, map your way up to the Ano Poli old town for sunset, and look up the bars and bakeries the city is famous for. Mobile data also makes sorting day trips out to Halkidiki simple.
Thessaloniki eSIM — online before you land →Heraklion · City guide
Heraklion is Crete's busy gateway and the jumping-off point for the Minoan ruins of Knossos. A Heraklion eSIM helps you find the palace site just outside town, navigate the old Venetian harbour and fortress, and book a hire car for the drive along the island's coast. With data on hand, using Crete's largest city as a base for the whole island becomes far easier.
Heraklion eSIM — online before you land →Rhodes · City guide
Rhodes pairs a UNESCO-listed medieval Old Town with long stretches of beach, and it's easy to enjoy both when you can stay connected in Rhodes. Map your way through the walled streets to the Palace of the Grand Master, check boat trips down to Lindos and its clifftop acropolis, and find a taverna among the cobbled lanes. Mobile data keeps the island's knights-era core and its coast equally within reach.
Rhodes eSIM — online before you land →Santorini · City guide
Santorini's whitewashed cliffs and caldera sunsets are among Greece's most photographed sights, and a Santorini eSIM helps you chase the best of them. Time your walk along the Fira-to-Oia path, book a catamaran trip out to the volcano and hot springs, and pin a sunset spot before the crowds arrive. With data running, sharing the view and navigating the cliffside villages both stay simple.
Santorini eSIM — online before you land →Mykonos · City guide
Mykonos moves fast, from the maze of Chora's whitewashed lanes to the beach clubs of the south coast, and a data plan for Mykonos helps you keep pace. Find your way past the iconic windmills and through Little Venice, book a boat over to the ancient site of Delos, and arrange a ride when the night drifts between beach bars. Staying online keeps the island's ever-shifting plans on track.
Mykonos eSIM — online before you land →Corfu · City guide
Lush and Venetian-flavoured, Corfu is an island for exploring by car as much as on foot. A Corfu eSIM lets you navigate the elegant Old Town below its two fortresses, map the winding roads to beaches like Paleokastritsa, and look up tavernas tucked into the green hills. With mobile data along, the Ionian island's mix of seafront promenades and inland villages is easy to roam.
Corfu eSIM — online before you land →Chania · City guide
On Crete's western side, Chania charms visitors with its Venetian harbour and lighthouse, and it's a fine place to stay connected in Chania while you wander. Map the old town's narrow lanes, book a trip down to the pink sands of Elafonissi or into the Samaria Gorge, and find a harbour-side spot for dinner. Mobile data makes basing yourself in this lovely port and venturing out across the west of the island straightforward.
Chania eSIM — online before you land →Why Horizon
