1 · The short answer: Ringo Light, 30 days

The eSIM for a month abroad I would buy is Ringo Light's 30-day Unlimited trip. It costs $22.99 in the USA, $26.99 in Germany, Spain, Italy and Turkey, $32.99 in Thailand and $35.99 in South Korea. It is sold as unlimited data at full speed, in one payment, with no renewal.

The reason is the gap. On their own pages on 11 November 2026, Holafly listed 30 days of unlimited in the USA at $73.90, and Airalo listed 30 days in Turkey at $69.00. The nearest rival price in each of these six countries is still higher than Ringo's.

I write for Ringo, so weigh that. I read every rival price below on the brand's own page today, in US dollars, and the links are in the last section.

2 · What a month abroad needs from an eSIM

A month is a long holiday, a work stint or a study month. You will use your phone for maps, video calls, rides and banking, so the plan has to last the whole stay and not run out in week two.

Ringo Light is a data-only travel eSIM that sits beside your own SIM, so your number keeps working for calls, texts and bank codes. The 30-day trip is one payment with no renewal. The eSIM arrives by email in seconds and installs with one scan, no app needed. The one line about limits is "Fair use policy, see Terms".

Ringo also sells the same 30-day trip at $26.99 in the UK, France, Greece, Portugal and the Netherlands, so most of Europe for a month sits at one price.

All four are 30-day plans sold as unlimited. Ringo is the lowest in every column, and the cheapest of the four I could read in all six countries. Italy is $26.99 at Ringo too, but I did not read the rivals' Italy pages, so I leave it out of the table.

4 · The biggest gaps, with both numbers

  • USA. Ringo $22.99 against Holafly $73.90, Airalo $68.00 and Maya Mobile $49.99.
  • Turkey. Ringo $26.99 against Holafly $73.90, Airalo $69.00 and Maya Mobile $49.99.
  • Germany. Ringo $26.99 against Holafly $76.50, Airalo $59.00 and Maya Mobile $49.99.
  • Spain. Ringo $26.99 against Holafly $66.50, Airalo $63.00 and Maya Mobile $49.99.
  • South Korea. Ringo $35.99 against Holafly $73.90, Airalo $69.00 and Maya Mobile $49.99.
  • Thailand. Ringo $32.99 against Holafly $73.90, Maya Mobile $49.99 and Airalo $49.00. This is the smallest gap, and Ringo still wins it.

The widest single gap I found is the USA against Holafly: $73.90 for the rival and $22.99 for Ringo. I found no country among the six where a rival was cheaper for 30 days.

5 · What each rival says about its 30-day plan

AiraloAiralo. The country pages showed six unlimited plans, from 3 to 30 days. The 30-day plan ranges from $49.00 in Thailand to $69.00 in Turkey and South Korea. The page I read gave no hotspot or daily figure that I could quote, so I quote none.

HolaflyHolafly. Holafly's USA page markets the plan as unlimited and notes that a temporary Fair Usage Policy may reduce speed for up to one day. It also prints 1 GB of shareable hotspot data per day of plan length. Ringo's line on limits is "Fair use policy, see Terms". Holafly was the dearest of the four in all six countries.

Maya MobileMaya Mobile. The cheapest rival, and the price is the same $49.99 on every country page I read, because the page sells its Global plan. The page says the 30-day option is a billing cycle that auto-renews while Travel Mode is on, and that you can turn it off. It also says "No caps, no throttling, no surprises." Ringo is $22.99 to $35.99 for the same month, one payment, no renewal.

Nomad. Its country pages returned no plan list to me, so I cannot give a Nomad price and I leave it out.

6 · Which one I would buy

  • A long holiday in Europe. Ringo's 30-day trip at $26.99 in Germany, Spain, Italy, France, Greece, Portugal, the Netherlands or the UK.
  • A work stint in the USA. Ringo's 30 days at $22.99, against $49.99 to $73.90 on the other three.
  • A study month in Asia. Ringo's 30 days at $32.99 in Thailand or $35.99 in South Korea. Japan is $54.99 for 30 days.
  • Longer than 30 days. Buy a second trip when the first one ends. I only compared 30 days here, so I give no longer-stay comparison.

Your own SIM stays active beside the eSIM, so your bank codes still reach you.

7 · Why Ringo for a month

One payment covers the month. There is no renewal to turn off, and no app to install. Setup takes one scan, and the eSIM arrives by email in seconds, so you can buy it the night before you fly.

The price gap is the main reason. A month with a rival costs $49.00 to $76.50 in these six countries, and a month with Ringo costs $22.99 to $35.99.

Ringo prices were read from the live catalogue on 11 November 2026. Nomad's country pages showed no plan list on that day, so Nomad is left out. I did not read Saily or the rivals' Italy pages.
