JamboSim eSIM Data Plans for Greece

JamboSim does not provide a true unlimited data eSIM for Greece. All of its Greece‑specific plans list a data cap of 3GB per day; after that limit the speed is reduced to about 1 Mbps.

If a traveler needs more data, JamboSim offers fixed data plans with larger allowances. For example, the eSIM JamboSim Europe 100GB / 180 days plan gives 100GB of high‑speed data for 180 days, and the eSIM JamboSim Europe 50GB / 7 days plan provides 50GB for a week. These fixed plans can be more cost‑effective for users who anticipate heavy data usage.

Yes, JamboSim offers eSIM plans for Greece that include a phone number and the ability to send SMS. The plans are named eSIM JamboSim Global+ and are available in data sizes from 1 GB to 20 GB, with validity periods ranging from 7 days to 365 days. Prices cover this range from $11.99 USD for the 1 GB/7‑day plan to $105.99 USD for the 20 GB/365‑day plan. Each plan assigns a phone number with the dialing code +1, so the number is an international (U.S.) line rather than a local Greek number. Calls and SMS can be sent from the eSIM, but inbound voice and SMS are not supported. Travelers who need specific inbound capabilities or local Greek numbers should confirm the details directly with JamboSim.

JamboSim offers a total of 80 plans for Greece, split into 12 single‑country and 68 multi‑country options. The plans come in both fixed data‐amount and daily data‑cap styles. Prices range from about $1.99 to $196.99, and data caps vary between 200 MB and 100 GB.
