Connectivity in Southern Europe: What to Expect in Greece
Southern European destinations attract massive tourist volumes that strain mobile networks during peak season. Beach resorts, historic city centers, and popular islands in Greece experience network congestion from June through September. Cosmote (OTE)'s network handles the load but speeds drop 15-25% in the most visited areas during peak hours.
Coastal and island coverage in Greece is generally good at established resort areas. Smaller islands and remote beaches may have weaker signal. Cosmote (OTE)'s tower density along popular coastlines is sufficient for navigation, messaging, and social media. Streaming quality depends on proximity to the nearest tower.
