Cosmote offers the widest network with the best island and rural reach.
Greece has good 4G across Athens, Thessaloniki and the main islands, with 5G now established in the cities and the larger tourist hubs. Cosmote holds the widest and most reliable coverage, including most of the popular Cyclades and Dodecanese islands. The realistic weak spots are the smaller and more remote islands, mountainous mainland regions such as the Pindus, and inter island ferry routes where signal comes and goes. For the main islands and cities, connectivity is dependable.
Typical local SIM: $15-25. Usually sold at operator stores in cities and larger island towns, plus kiosks (periptera); airport counters at Athens. A passport is required to register a Greek SIM. EU carrier terms is included on most prepaid plans, so a single Greek or EU eSIM covers an onward trip through the wider EU under the carrier terms. On the smaller islands, finding an operator store can be harder than expected.
For island hopping and short trips a travel eSIM is the easiest choice, since it spares you finding a shop on a small island. For a long stay a local pack is cheaper per gigabyte.
the widest network with the best island and rural reach, the strongest single choice for island hopping.
strong coverage on the main islands and in the cities, very reliable in tourist areas.
competitive pricing and good urban and large island coverage, weaker on the smallest islands.
you want to land connected for an island trip without hunting for a store on arrival, or you are combining Greece with other EU stops.
you are based on the mainland or a large island for a month or more and want the lowest price per gigabyte from a local Cosmote pack.
No first-hand measurement has been published for Greece yet. This page will update automatically when a validated field test is added to the shared dataset.
Use this page to compare the current price per GB, network indicator, transparency signal and local-operator reference for Greece. It also links to a destination calculator and plan page.
It is the median price per GB of mid-tier plans in the live Greece catalogue. Small 1 GB teasers and 50 GB or larger bulk plans are excluded so the figure reflects a typical traveller choice.
The page shows the current 5G coverage indicator, a transparency score and the main local operator. These are destination-level signals, not a guarantee for every street or device.
The decision section compares the practical trade-offs. A travel eSIM is usually simpler for a short visit; a local SIM can make sense when you need a local number, longer service or local pricing. Check the current conditions before deciding.
Price per GB is the median of mid-tier plans from the live Greece catalogue. Network and transparency indicators come from the shared Drift dataset and are refreshed monthly.
