Tips for Travelers in Greece
Make the most of your Greece trip with these connectivity tips from fellow travelers:
Download and install your AloOui Greece eSIM profile at home before departure. It won't activate until you land — so you're ready the moment you step off the plane at Athens International Airport Eleftherios Venizelos.
Your AloOui eSIM runs alongside your existing SIM. Keep your home number for calls and WhatsApp while using the Greece eSIM for data — no need to choose.
Before island-hopping to smaller Cyclades islands or exploring remote mountain villages, download offline maps on Google Maps or Maps.me. Even with unlimited data, offline maps save battery and load instantly in areas with weaker signal on the islands.
On the Unlimited Lite plan, enable Low Data Mode on your phone to stretch your 1GB daily full-speed quota further — great for sightseeing days with light usage.
Greece's top experiences — Acropolis timed entry tickets, Santorini sunset tours, Delphi day trips, and Meteora monastery visits — fill up fast in peak season. Use your AloOui data to book online the moment you arrive, or even on the plane.
Greek island ferries and intercity buses have limited or no onboard Wi-Fi. Use your AloOui eSIM for reliable connectivity between Athens, Thessaloniki, Patras, and across the islands throughout your journey.
For Business Travelers & Digital Nomads
Greece is a growing hub for business travel and digital nomads — from Athens' thriving Syntagma and Kifissia business districts to the booming tourism and shipping sectors. Here's why AloOui's Unlimited Plus is the go-to plan for professionals.
The Plus plan gives you network priority — so even in crowded business districts, airports, or busy Athens neighbourhoods, your connection stays fast and stable.
Video calls, large file uploads, cloud syncing — 2GB of full-speed data per day keeps your workflow uninterrupted, with 2 Mbps fallback for lighter tasks.
Share your connection with your laptop or tablet. Perfect for working from an Athens café, a hotel in Thessaloniki, or a villa in Santorini without relying on public Wi-Fi.
Extended stays covered. Whether you're on a month-long business trip in Athens or island-hopping across Greece's diverse regions, one plan keeps you connected the whole time.
Scan a QR code and you're online. No SIM procurement, no corporate roaming plans, no waiting at a carrier store. Instant activation means you're productive from day one.
One flat rate, no surprise roaming bills. Ideal for expense reporting and budget-conscious professionals who need reliable data without unpredictable carrier charges.
