eSIM Travel Tips for Greece

Set up your eSIM before departure
Install your HelloRoam eSIM at home before flying to Greece. Enable mobile data at Athens Eleftherios Venizelos Airport and you are connected straight away. No airport SIM kiosk needed.
Download offline maps for island hopping
While popular Aegean islands have good coverage, smaller and more remote islands can have weaker signal. Download offline maps for each island before taking the ferry from Piraeus.
Save data during peak summer heat
Greek summer (July to August) sees massive tourist influx. Urban networks can be busy near the Acropolis and Santorini caldera. Download local guides and restaurant recommendations offline before peak hours.
Track your data balance
The HelloRoam app shows your data balance in real time with alerts at 80% and 95%. Top up from the app without reinstalling your eSIM if you run low.
Know the Greek emergency number
Greece's emergency number is 112 for all services. Police is 100, ambulance 166, and coast guard 108. Save these before you travel. They work on any network without a data balance.

$10.00–$20.00/day

Best Time to Visit Greece

Greece peaks in summer (June to August) when the islands are busiest and warmest. Spring (April to May) and early autumn (September to October) offer great weather with fewer tourists and more manageable network conditions. Athens is a year-round destination with mild winters. The Greek islands are largely seasonal, with many businesses closed from November to March. Always download offline maps before remote island hopping.
