Yesim Review 2026: Plans, Prices, and Travel Alternatives

Yesim is a travel eSIM provider founded in 2019 in Switzerland. The company had approximately 300,000 customers in 2024 and now claims to have over one million users. It is younger and smaller than Airalo or Holafly, but it has carved out a niche for itself with competitive pricing and a unique offering.

Who is behind Yesim?

The company is headquartered in Switzerland, with additional offices in the United Arab Emirates and Europe. The brand operates through two main platforms: yesim.tech and yesim.app. It partners with major local mobile carriers in each country to ensure coverage, such as T-Mobile and Verizon in the U.S., AIS in Thailand, and Türk Telekom, Turkcell, and Vodafone in Turkey.

The 3 types of Yesim plans

Regional and global eSIMs

If you’re traveling to multiple countries, Yesim also offers plans that cover an entire region. Ten regions are available: Europe (31 countries), Asia-Pacific (15 countries), North America (3 countries), South America (11 countries), the Caribbean (14 countries), the Middle East (8 countries), Africa (15 countries), Scandinavia (6 countries), Central Asia (6 countries), and Southeast Asia (8 countries). Two global plans round out the catalog: one covering 147 countries, and another covering 82 countries.

After carefully reviewing their proposal, here are Yesim’s real strengths in 2026.

• ✅ Some of the lowest starting prices on the market. The Pay & Fly plan starts at $0.54 for France, and Standard plans can cost less than $2 per GB for certain destinations such as Turkey or the United Kingdom.
• ✅ Extensive coverage. Over 135 countries covered by single-destination plans, with more than 200 destinations in total when including regional plans. All major tourist destinations are covered.
• ✅ Fixed-rate AND unlimited plans. This is rare: many competitors force you to choose their plan. Yesim lets you choose based on your usage.
• ✅ Virtual phone numbers. A lesser-known feature that lets you receive OTP codes and verification texts without using your personal number. The available numbers are from the Netherlands, the U.S., Canada, and Israel.
• ✅ Payment in euros is accepted. Unlike Airalo, which only charges in dollars, Yesim displays its prices in euros, dollars, and pounds sterling.
• ✅ Tethering is enabled. You can share your data with another device using hotspot mode.
• ✅ The Pay & Fly plan (pay-as-you-go). You purchase credits and use them at your own pace; there is no time limit on the eSIM.
• ✅ A free VPN built right into the app. Handy for keeping your browsing secure on public Wi-Fi networks.
• ✅ 30-day refund policy if the eSIM has not been used.

Here are the issues to watch out for. And there are a few you should be aware of before you pull out your credit card.

The Ycoins system: a source of complications

Yesim uses a virtual currency called Ycoins: 100 Ycoins cost €0.81 or $1.00, depending on the currency. To purchase a plan, you first top up your account with Ycoins, then spend those Ycoins. In practice, this complicates the purchase: you have to estimate how many Ycoins to buy, you might end up with too many (non-refundable, usable only at Yesim), and it adds an extra step compared to a direct payment. Several users on Trustpilot complain about this hurdle.

Customer support is primarily available in English and Russian

This is probably the biggest drawback for French speakers. Yesim’s customer support is available via live chat, WhatsApp, and email, but the official languages are English and Russian. Other languages are accepted, but responses are automatically translated, with the risk of errors that this entails. When you’re in Tokyo without internet and need to resolve an activation issue, it’s reassuring to have support in your own language.

A less smooth installation process

The setup process for Yesim isn't as seamless as that of its competitors. You first have to create an account, then buy Ycoins, then choose a plan, and finally install the eSIM. That's several steps, whereas Airalo and voilà offer a direct purchase option.

Mixed feedback from the field on certain destinations

Unlimited plans are more expensive than Holafly (outside Europe)

If you're looking for unlimited data, Holafly is generally cheaper for long-haul destinations (the U.S., Asia). Yesim remains competitive in Europe but loses its edge elsewhere.

Automatic Ycoin top-up is enabled by default

Something to keep in mind: after your first top-up, Yesim automatically enables a feature that automatically reloads your account with Ycoins if your balance falls below a certain threshold. You’ll need to disable it manually if you don’t want it. It’s a real trap for users in a hurry.

Let’s look at the actual figures. Yesim’s prices are listed in euros, dollars, and pounds sterling (a plus), and vary depending on the type of package, the destination, and the duration.

Standard Packages: Prices by Destination (2026)

Here are the prices listed in 2026 on the Monito comparison site for popular Standard plans:

Unlimited Plans: Prices by Destination

Unlimited plans are more expensive but free you from worrying about data limits:

Pay & Fly: Price per GB depending on the country

With Pay & Fly, you only pay for what you use. Current rates:

For flights to Turkey or Thailand, Pay & Fly is a really good deal. For flights to Japan, however, a Standard package will be more cost-effective.

How do Ycoins actually work?

Real-life example: With €20 in Ycoins (including bonuses), you can purchase a 5 GB global data plan that normally costs €35. Ycoins can therefore lead to real savings if you take advantage of promotions and referral programs.

Please note, however: Ycoins are non-refundable, and auto-recharge is enabled by default. Turn it off as soon as you log in for the first time if you don't want it.

5G is available, but coverage varies

The 10 regions covered

Please note: Regional plans are slightly more expensive than single-country plans. You should only choose them if you are actually traveling between multiple countries.

To get an unbiased view, we compared the ratings across the three major platforms:

The ratings are generally very good. About 76% of users give it five stars. But you have to look beyond the average.

Consistent positive feedback

• Quick and easy setup via the app.
• Very competitive prices, especially on smaller packages.
• Internet sharing that actually works.
• The validity period does not begin until arrival in the country.
• The attractive referral bonus.
• Customer service described as responsive and personable in Trustpilot reviews from 2026.

Common complaints (you should be aware of)

• Unstable connectivity in certain exotic destinations (Algeria, Nepal, Mauritius, and some parts of the Maldives).
• Confusion surrounding Ycoins and the default automatic top-up feature.
• Too many notifications from (email and app), according to Monito.
• Support is available in Russian and English, which can lead to misunderstandings.

Negative feedback remains in the minority (about 10%), but it is a recurring issue regarding these specific topics.

What does it do better th? Simplicity, transparency, and French-language support. No intermediary virtual currency, no automatic top-ups by default, and genuine customer service in French. For French-speaking travelers who want to get straight to the point, voilà clearly simplifies the experience.

What Yesim does best: virtual numbers (a real standout feature), the Pay & Fly plan for long-term travelers, and unlimited plans for certain countries.

After a thorough analysis, here is our clear-cut opinion.

Yesim is a good choice if:

• You're on a tight budget and are looking for the absolute lowest price.
• You need a virtual number to receive verification text messages.
• You're going on a long trip through multiple countries, and Pay & Fly is the right choice for you.
• You are comfortable using English for customer support.
• You agree to the Ycoins system and its features.

Here's what would be better:

• You prefer responsive, personalized customer support in French.
• You want transparency: the listed price is the final price—no virtual intermediary currency.
• You prefer simplicity (direct purchase, activation in 2 minutes).
• Are you traveling to popular destinations (Japan, Thailand, South Korea, the U.S., Europe) where competition is fierce?

All in all, Yesim is a solid provider with real strengths, but also some drawbacks that French speakers should be aware of before signing up. If simplicity and transparency are important to you, check out voilà.
