Tips for Travelers in Greece

Make the most of your Greece trip with these connectivity tips from fellow travelers:

Install Before You Fly

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.

Keep Your Home SIM Active

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.

Download Offline Maps

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.

Use Data-Saving Mode

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.

Book Ferries & Experiences Early

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.

Stay Connected on the Go

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.

Max Priority 4G LTE

The Plus plan gives you network priority — so even in crowded business districts, airports, or busy Athens neighbourhoods, your connection stays fast and stable.

2GB/day Full Speed

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.

Hotspot & Tethering

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.

Up to 30 Days Coverage

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.

No IT Setup Required

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.

Predictable Costs

One flat rate, no surprise roaming bills. Ideal for expense reporting and budget-conscious professionals who need reliable data without unpredictable carrier charges.
