TailSim eSIM Data Plans for Greece

TailSim does not provide a truly unlimited data eSIM for Greece. The plans that carry “Unlimited” in their name give 3GB of high‑speed data per day and then throttle the speed to 512kbps once that daily limit is reached, so the data is still capped.

If you need a larger, fixed amount of data, TailSim offers several fixed‑data plans for Greece, such as 50GB for 30 days, 20GB for 30 days, and 10GB for 30 days. These plans give a set amount of high‑speed data that must be used within the validity period and can be more cost‑effective for most travelers.

TailSim does not offer a Greece eSIM that includes a phone number or SMS capability. The available Europe plans are data‑only, so travelers must rely on internet‑based messaging and calling apps such as WhatsApp, Telegram, or iMessage over the data connection. While these apps normally work in Greece, some destinations can block or restrict specific services, so it is advisable to confirm that the messaging or calling apps you rely on are accessible before purchasing a plan.

TailSim provides 14 single‑country data plans and 14 multi‑country plans that cover Greece. The plans range from $3.99 to $85.50, offering data caps between 1 GB and 50 GB. Some of the options are fixed‑data plans that give a set amount of data for the whole validity period, while others are daily‑data‑cap plans that reset each day, giving users flexibility to control daily usage in addition to the overall allowance.
