Greece remains one of the most popular summer destinations for UK travellers, and whether you're heading to Athens, the islands, or both, getting connected with eSIM is usually straightforward.
Does eSIM work in Greece?
Yes. Greece's three main networks — Cosmote, Vodafone Greece, and Nova — all support eSIM, and coverage is strong across Athens, the mainland, and the more visited islands including Santorini, Mykonos, Crete, and Rhodes. As with any island-heavy destination, coverage can weaken on smaller or less-developed islands, so if you're heading somewhere off the typical tourist route it's worth checking coverage maps for that specific location beforehand.
Most travel eSIM providers, including those we compare here, resell data allowances across these Greek networks rather than requiring you to set up an account with a Greek provider directly.
How to check if your phone supports eSIM
On iPhone, go to Settings > General > About and look for an EID number, or check Settings > Cellular for an "Add eSIM" option. On Android, check Settings > Network & Internet for "Add eSIM" or "Add Mobile Plan". Most iPhones from the XS onwards support eSIM, as do most Android flagships from around 2020 onwards, though it's worth checking directly rather than assuming based on release year alone since some budget models still don't support it. Our full guide to how eSIM works covers this in more detail.
Setting up an eSIM for Greece before you fly
- Buy your eSIM in advance, on wifi at home rather than at the airport — most providers deliver a QR code by email or app within minutes.
- Install it before you travel — scanning the QR code doesn't activate the plan immediately, so there's no risk in setting it up days ahead.
- Keep your UK SIM as your primary line for calls and texts, setting the new Greece eSIM as your data line, so your usual number stays reachable without roaming charges.
- Enable data roaming for the new eSIM only — leave it off for your UK SIM unless you want UK roaming rates applying too.
- Land and connect — no shop counters, no PIN codes required.
eSIM vs a physical Greek SIM
For a typical one or two-week trip, an eSIM is the simpler option — set up before you fly, connected the moment you land. For longer stays, or if you want the lowest possible cost per GB, a physical SIM from a Cosmote or Vodafone shop once you're in Greece can be cheaper, though this means dealing with a shop counter, and availability can be patchier on smaller islands than in Athens.
If you'd rather sort connectivity before you leave, compare current travel eSIM options here, including coverage specific to Greece and the islands.
Island-hopping and multi-stop trips
If your trip covers multiple islands, or Greece is one stop on a wider Mediterranean trip, check whether your eSIM provider offers a regional plan rather than buying a single Greece-only allowance — it's often better value and saves managing multiple separate eSIMs. Our guide to picking an eSIM app for travel covers how to compare regional versus single-country options. If Turkey is also on your itinerary, the same setup process applies there — the steps are essentially identical destination to destination.
Protecting your phone on the islands
Boats, beaches, and cobbled island streets are exactly where phones get dropped, soaked, or lost. If your current phone isn't already covered, it's worth checking gadget insurance options before you travel rather than after something happens.
What if I lose signal on a remote island?
Even with a working eSIM, some smaller Greek islands and more rural mainland areas can have genuinely patchy mobile coverage, particularly away from main towns and resort areas. It's worth downloading offline maps and any accommodation or ferry booking confirmations before you leave wifi, so you're not relying entirely on a live connection if signal drops out somewhere remote. This is good general travel practice regardless of which eSIM or SIM option you choose.
Sticking with a UK SIM plan instead
If travel eSIMs feel like more hassle than they're worth, some UK SIM-only plans include decent international roaming as standard. Compare current SIM-only deals with roaming included here, or browse our full SIM-only comparison if that suits how you travel better.
Before you fly
If you're due a phone upgrade before your trip, it's worth sorting it beforehand rather than travelling on a phone close to the end of its life. Compare refurbished phones with confirmed eSIM support, or if you're planning to sell your current phone once the new one arrives, get a live trade-in price here before you decide.
