Practical Santorini guide
Mobile Internet & Wi-Fi in Santorini
Practical connectivity guidance for Santorini: roaming, SIM/eSIM choices, hotel Wi-Fi and remote-work backups.
Roaming
EU/EEA roaming arrangements depend on your mobile plan and country. UK and other non-EU travellers should check their provider’s current Greece charges before arrival.
Wi-Fi
Hotels and cafés commonly provide Wi-Fi, but speed and reliability vary by property and room location.
For remote work
Ask for a recent speed test from the exact accommodation and keep mobile data as backup.
Coverage
Terrain and building construction can affect signal. Do not assume a caldera cave room has the same reception as an outdoor terrace.
