Comet SIM does not provide any Greece eSIM plan that includes a phone number or SMS capability. All plans sold by Comet SIM for Greece are data only. Travelers who need voice or text will need to rely on VoIP applications such as WhatsApp, Telegram, and iMessage, which usually work over the data connection. These apps are generally available in Greece, but some destinations may restrict or block specific VoIP services, so it is advisable to verify that the applications you plan to use can be accessed before purchasing a plan.

The available plans range in price from about $3.90 to $119.90 and provide data caps between 1 GB and 20 GB, with validity periods from 7 to 30 days. The single‑country options give a fixed data amount for use only in Greece, while the multi‑country plans allow the same data to be used across several destinations, offering flexibility for travelers who visit more than one country during their trip.
