The short answer
This one is for an American with AT&T or Verizon who is flying to Athens and planning a few islands. I read both carriers' day-pass pages on 31 October 2026 and set them against the five travel eSIMs and Ringo Light, priced on 25 October 2026. For a day I would roam. For a long weekend, two weeks or a month I would buy Ringo Light, and leave my own SIM in the phone for calls.
Unlimited data at full speed for 2 weeks at $14.99 or 30 days at $26.99, paid once, nothing renews. Airalo asks $48 for 15 days and $69 for the month.
10 GB for 30 days at $12 and 25 GB at $22, on Nova with 5G, if maps and ferry tickets are most of what you do.
20 GB for 30 days at $21 on Nova and Vodafone. Its 3 days of unlimited is $11.
Days, not gigabytes, on Vodafone and Nova, with no daily cap stated for your own phone. It warns that coverage is limited on remote islands.
Prices read on 25 October 2026: Airalo, Holafly, Saily, Nomad, Ubigi, AT&T, Ringo Light, Verizon on their own sites or listings, Ringo Light from its catalogue. All in US dollars unless stated. Treat every number as a snapshot.

The prices, charted
US dollars, 25 October 2026. The rivals sell 15 days, Ringo Light 2 weeks. Ubigi's 15 days is 30 GB at full speed, then 2 Mbps. Nomad sells no 15-day unlimited.
The 30-day plan at each brand. Ubigi's month is 60 GB at full speed, then 2 Mbps.
Holafly sells no buckets. Ringo Light sells no bucket either: its 2 weeks is unlimited and lasts 2 weeks, not 30 days.

Want to keep your own number abroad?
That is the full Ringo service: one plan that works everywhere, with your own number included.
It is a separate product from Ringo Light and it is still being built, so it is not on sale yet. Join the waitlist to hear when it opens.
What to see in Greece, and what your phone needs for it
Eight places most first trips include, from Athens to the islands, with the one thing your data does for you at each. The big sites have strong signal, and the small islands are where offline maps earn their place.
Roam with your carrier, or buy an eSIM
AT&T's International Day Pass is $12 a day on land, read 31 October 2026. Its destination list names Greece with no separate price, so $12 is the page's land rate. Three days is $36, two weeks of daily use is $168 and a month is $360. Verizon's TravelPass countries list shows Greece at $12 per day on the same date. Ringo Light is $8.99 for 3 days, $14.99 for 2 weeks and $26.99 for 30 days, unlimited data at full speed, paid once.
So a fortnight of Ringo Light is $153.01 under either day pass, and a month is $333.01 under. The cheapest rival is still well above Ringo Light: for 15 days Ubigi asks $36 for 30 GB at full speed, Airalo $48; for a month Ubigi asks $55 and Airalo $69. For 3 days, Ringo Light's $8.99 sits under Nomad's $11 and Airalo's $11.50.
The carrier has its own wins, and I would name them. Your own number keeps ringing, calls and texts are included, there is nothing to install and no eSIM slot to find. Both bill only for days the phone is used in Greece. One day on the pass is $12, which is more than the whole 3-day eSIM, so I would roam only when the phone will barely come out of your pocket.
On AT&T, each additional line used the same day adds $6. Two of you on the ferry from Piraeus is $18 a day, against two eSIMs for a fortnight at $29.98.
Networks in Greece, and what changes for a visitor from the United States
Greece has three networks: Cosmote, the largest, then Vodafone and Nova. On Santorini, Mykonos, Crete, Rhodes and Corfu all three work well. On the smaller islands and in the mountains the signal can fall to 4G or thin out. In the table, Airalo names Nova and one other, Holafly Vodafone and Nova, Nomad Nova and Vodafone, Ubigi Nova, and Saily Cosmote or Vodafone. Ringo Light rides a local partner network. I would download offline maps and ferry tickets before leaving port.
For a visitor, what changes is the billing. AT&T and Verizon charge per day of use, on the line you already pay for. Verizon says each 24-hour session gives 5 GB of high-speed data, then unlimited data at 3G speeds. AT&T describes unlimited high-speed data when the pass is added to an eligible unlimited plan, and says speed and coverage vary by destination, which matters on a remote island. The eSIMs are bought ahead and run for a set number of days.
The pages I read show no monthly plan for Greece, so I took the month as thirty days at $12.
If you want a data bucket: Ubigi or Nomad
- Ubigi, $12 for 10 GB. The cheapest 10 GB for 30 days, and 25 GB for $22, on Nova with 5G. No app is needed, as I read it.
- Nomad, $18 for 10 GB. 20 GB for $21 is the cheapest 20 GB I read, $5.99 under Ringo Light's 30 days. On Nova and Vodafone.
- Saily, $22.99 for 10 GB. On Cosmote or Vodafone. Its 20 GB is $35.99, read on saily.com on 25 October 2026.
- Airalo, $20 for 10 GB. 20 GB at $35.50, with small buckets from $4 for 1 GB.
- ✓Ringo Light, no buckets. Its 2 weeks is unlimited at $14.99 and its 30 days unlimited at $26.99. For 10 GB that lasts a month, Ubigi at $12 is the better buy, and Nomad sells 20 GB for $21. I would rather you read that here than at checkout.
What Ringo Light is
Ringo Light is the data eSIM from the company I write for, so keep that in mind when you weigh my pick. It is sold to fund the full Ringo, one plan that works everywhere with your own number ported onto it. For Greece it sells three trips, all unlimited data at full speed: 3 days at $8.99, 2 weeks at $14.99 and 30 days at $26.99. Nothing renews. The eSIM arrives by email and installs in one scan, no app.
It sits next to your own SIM, so your number keeps working for calls and texts if you leave roaming on for those, which both carriers include. I would run the data on the eSIM and let the carrier handle calls.
The card to buy it is further up this page, just after the side-by-side table.
Pick by trip
I would roam on the carrier at $12. It is the only case where I would pick the pass.
I would buy Ringo Light at $8.99, against $36 on the pass and $11 at Nomad.
I would buy Ringo Light at $14.99, against $168 on either day pass and $36 to $51.50 at the rivals.
I would buy Ringo Light at $26.99. The carriers come to $360, and the cheapest rival month is Ubigi at $55.
Ubigi 10 GB for 30 days at $12, if you will mostly use maps and ferry tickets.
I would keep the carrier SIM in the phone with roaming on for calls, and put the data on Ringo Light.
