Best Local SIM Cards for Tourists in Greece (2026)

Top ranked places

We prioritized verified local Greek mobile operators first because a physical SIM card in Greece for tourists can provide a local network relationship and sometimes a Greek number, while travel eSIMs are usually easier before arrival but may be data-only and dependent on partner networks. Exact prices, allowances, hotspot rules, fair-use limits, airport stock, and activation steps change often, so readers should confirm the latest plan directly with each provider before buying.

1. #1 Cosmote Greece SIM

   Cosmote Greece SIM is the traveler profile for COSMOTE, the Greek mobile network brand operating at the official domain cosmote.gr from Athens, Greece. It is the best local SIM card for tourists in Greece when the priority is local-network performance across mainland Greece and islands rather than the fastest online setup. Confirm the latest Cosmote tourist SIM, prepaid SIM, eSIM eligibility, store process, and package details directly before purchase.

   • Best for: Best overall local network pick for coverage-focused travelers
   • Known for: Greek mobile network, prepaid SIM, eSIM activation, mobile internet in Greece
   • Why it ranks here: Independent 2026 network evidence reports Cosmote leading several Greek mobile experience categories, including coverage and speed signals, and official Cosmote sources document mobile, prepaid, and eSIM-related services.
   • Evidence signals: Supported by Cosmote official pages and Opensignal’s 2026 Greece mobile network experience reporting. We did not lock exact prices, data allowances, or airport availability because those details change frequently.
