eSIM Travel Tips for Athens
Athens flights from Australia are long but worth it
Athens is roughly 17 to 21 hours from Sydney via Dubai, Singapore, or other connections. Greece is extremely popular with Australian tourists, particularly those combining Athens with Greek island-hopping. Activate your HelloRoam eSIM at home before you fly to hit the ground running at ATH.
EU roaming makes Greece a multi-destination option
A HelloRoam Greece eSIM covers Greece only, but the HelloRoam Europe plan covers multiple European countries on one eSIM. If your trip combines Athens with a cruise to Croatia, a ferry to Italy, or a flight to Paris, your plan works across those EU destinations. Check plan terms for any specific conditions.
Visit the Acropolis early in the morning
Summer crowds at the Acropolis are intense and network speeds can slow near the Parthenon during peak hours. Download your audio guide before ascending. The main entrance and viewing areas all have outdoor 4G throughout the day.
Piraeus ferry port access
Piraeus, the main departure point for Aegean island ferries, has strong outdoor 4G across all ferry terminals for Santorini, Mykonos, Crete, and the Cyclades. You can book last-minute ferry tickets and check departure boards on your HelloRoam eSIM from the port.
Metro dead zones on Line 1
The Athens Metro has 4G at most stations on lines 2 and 3. The older Line 1 (green line) has less consistent underground coverage. Line 3 to the airport keeps signal throughout. Download your route before going underground for older line sections.
Mobile networks in Athens: Cosmote and Vodafone Greece
Athens is served primarily by Cosmote and Vodafone Greece. Cosmote, part of Deutsche Telekom, runs the strongest 4G and earliest 5G network in the city.

Vodafone Greece provides parallel 4G with strong performance in Piraeus, the southern suburbs, and the northern business districts.

Best time to visit Athens from Australia
April to June and September to October offer the best Athens weather for sightseeing. April and May are warm at 18 to 26 degrees with fewer crowds at the Acropolis and the Ancient Agora. October is excellent with comfortable temperatures and sea still warm for coastal day trips. July and August are the hottest months at 36 degrees or above. Morning visits starting at 8am are manageable before noon heat. August sees many Athenians leave for the islands, making the city quieter but some local businesses closed. Winter from November to February is cooler at 8 to 14 degrees, quieter, and good for museum visits.

Cat
On a trip to Europe, my hotel Wi-Fi was so slow and outside Wi-Fi was unreliable. I couldn’t take it anymore so I got helloroam for a few days. It was tricky to set up correctly because of the primary settings (with my original number). But I reached out to their customer service via WhatsApp. Super responsive and helpful, with specific and clear steps to troubleshoot. Appreciate having 4G roaming instead of being stuck with in and out Wi-Fi during my trip!!
Rated 5 out of 5 by this reviewer
Very good experience! The eSIM was easy to set up and worked great in London. It was much cheaper than it would have been to use my own operator there.
