eSIMs are small tools that have made travelling much easier. You no longer need to waste time looking for a physical SIM card when you arrive at your destination, nor pay expensive roaming fees. Among the available options, you’ll find Yesim, an app that simplifies your internet connection in over 120 countries through a very convenient and easy-to-use digital system.
For many travellers, it’s the ideal solution. But is it really? In this guide, we’ll take a close look at how it works, what it offers, and what Yesim reviews from real users reveal about their experience.

What Is Yesim?
Yesim is an app that offers mobile data plans through eSIM — the digital SIM cards installed directly on your phone without physical hardware. The idea’s actually very simple. The concept is simple: you just download the app, choose the plan that suits your destination, and activate the connection in minutes.
The company was created to make mobile connectivity more accessible for frequent travellers, students abroad, and anyone needing internet in another country.
On Yesim’s official website, you can see that it’s available in over 120 countries and compatible with most modern phones that support eSIM.
Basically, Yesim positions itself as an alternative to local SIMs and traditional roaming. You don’t need to wait for deliveries or visit a physical store, which is already a great advantage for travellers who seek maximum convenience. However, as we’ll see later, not everything is that simple. It’s important to review what it truly offers regarding coverage, pricing, and support.
How Does Yesim Work?
Yesim works very simply, even for those who’ve never used an eSIM before. The whole process happens within its app, available for both iOS and Android. It can be summarised in four main steps:
- Download the app: You can install it for free from the App Store or Google Play.
- Sign up: You only need an email address or an Apple/Google account to start.
- Select a data plan: The plans are divided by countries or regions (Europe, Asia, America, etc.) and display data amount and duration.
- Install the eSIM: Once you’ve bought your plan, the app generates a QR code or automatic profile that installs on your phone. Within seconds, your device will be ready to connect to the internet at your destination.
As you can see, everything happens digitally. You don’t need to queue in a store, wait for shipping, or contact local operators. The installation is step-by-step and very straightforward, so errors are unlikely.
Yesim works with the majority of phones that support eSIM. If your device isn’t compatible, the app detects it instantly and warns you before purchase.
Another useful feature is that the app lets you keep more than one active eSIM. This means you can keep your regular line and activate Yesim’s data plan during the trip to switch between both. This flexibility helps since you won’t lose access to your main number.
In short, the user experience is one of Yesim’s biggest advantages. You don’t need technical knowledge, and you can manage everything easily from the app.
Analysis of Yesim’s eSIM: What It Offers
Once that’s clear, the next question is how much Yesim costs, where it offers coverage, how to pay, and what kind of help you’ll get if something goes wrong. Let’s answer these questions with clear and practical details.
Prices
Yesim’s prices vary depending on destination and data allowance. Plans are divided by country or region. Below, you’ll find a few examples taken from its official website:
| Region / Country | Basic Plan (1 GB / 7 days) | Medium Plan (3 GB / 15 days) | Wide Plan (10 GB / 30 days) |
| Europe | $5.50 (€5.00) | $13.20 (€12.00) | $31.90 (€29.00) |
| United States | $5.00 (€4.50) | $12.70 (€11.50) | $30.80 (€28.00) |
| Mexico | $6.60 (€6.00) | $15.40 (€14.00) | $35.20 (€32.00) |
| Japan | $7.70 (€7.00) | $17.60 (€16.00) | $41.80 (€38.00) |
| Global (120 countries) | $9,90 (€9,00) (500 MB / 7 days) | $26,40 (€24,00) (3 GB / 15 days) | $71.50 (€65.00) (10 GB / 30 days) |
Overall, prices are highly competitive compared to similar apps. However, the global plan is slightly more expensive per gigabyte.
Coverage:
Coverage is a key factor when choosing an eSIM. Yesim claims to operate in over 120 countries through agreements with local carriers. However, connection quality may vary:
| Region | Main Countries Included | Network Type |
| Europe | Spain, France, Italy, Germany, United Kingdom, etc. | 4G LTE |
| North America | United States USA, Canada, Mexico | 4G LTE |
| Latin America | Brazil, Argentina, Chile, Colombia, Peru | 4G LTE |
| Asia | Japan, China, South Korea, Thailand, India | 4G LTE |
| Africa | South Africa, Morocco, Egypt | 3G/4G LTE |
| Global | 120 countries in total, with different networks | 3G/4G LTE |
In Europe and North America, coverage is stable and mostly 4G. In Asia and Latin America, it depends on each country and carrier, though it usually works fine in major cities.
Payment Options
One of Yesim’s advantages is that it accepts multiple payment methods, perfect for users from different countries:
| Payment Method | Availability |
| Credit/debit card (Visa, MasterCard, Amex) | Yes |
| PayPal | Yes |
| Apple Pay | Yes |
| Google Pay | Yes |
| Cryptocurrencies (Bitcoin, Ethereum, USDT) | Yes |
| Yesim Gift Cards | Yes |
Accepting cryptocurrency is a distinctive advantage compared to other companies in this industry.
Customer support
Support is another essential aspect, as eSIM issues may appear when you reach your destination. In this regard, Yesim offers several communication channels:
| Support Channel | Availability |
| In-app chat | 24/7 (mainly in English) |
| Yes (usually replies within 24 hours) |
| Online Help Centre | Yes (FAQ and tutorials) |
| Phone | Not available |
| Support Languages | English (main), limited Spanish |
The integrated chat works quickly but mostly in English. For travellers who don’t speak it, this may be inconvenient, as automated replies don’t always solve complex issues.
Therefore, Yesim meets the basics: clear plans, wide coverage, and various payment methods. However, customer service could improve, especially for users who prefer Spanish support while travelling.

Advantages of Yesim
Yesim has several strong points that explain why it’s the preferred choice for many travellers. On its website and across user forums, several benefits stand out that deserve mention:
| Main Advantages | Details |
| Easy installation | Everything is managed through the app within minutes, with no physical SIM required. |
| Wide coverage | Available in over 120 countries through agreements with local operators. |
| Flexibility | Lets you keep several eSIMs active along with your regular line. |
| Varied payment options | Includes card, PayPal, Apple/Google Pay, and even cryptocurrencies. |
| Regional and global plans | You can buy per country, region, or global coverage. |
| No contracts or commitments | You only pay for the plan you need, with no mandatory subscriptions. |
Therefore, Yesim stands out for its convenience and speed. It’s a very handy solution if you don’t want complications when arriving at a new destination.
Disadvantages of Yesim
However, not everything is positive. Some reviews and comparisons highlight weaknesses that should also be considered:
| Main Disadvantages | Details |
| Limited customer service | Support is mostly in English, and there’s no contact phone line. |
| Higher global prices | The worldwide plan is helpful but costs more per gigabyte than others. |
| Not all phones supported | Requires an eSIM-compatible device, so older models are excluded. |
| Uneven quality by country | In parts of Africa or rural Asia/Latin America, the connection may be unstable. |
| No calls or SMS included | It only provides data. If you need a local number, you must use another service. |
Yesim performs very well in popular destinations and on recent devices. However, it may fall short if you travel to areas with limited coverage or need a service that includes calls and native-language support.
A similar situation occurs with other providers such as Latam. Many users search for guides on how to cancel their plans, for example, as you can see in this article about the Latam eSIM.
What Do Users Say About Yesim?
When choosing an eSIM, nothing’s more revealing than hearing from those who’ve already tried it. On Trustpilot, one of the most popular review platforms, Yesim has an average rating of 4.3 out of 5, showing a high satisfaction level compared to similar services.
Among the positive comments, many users praise its easy installation and how quickly they connected once arriving at their destination. In just two or three minutes, you can get online and even switch networks automatically without doing anything.
However, criticism also appears. The most frequent one is the lack of English support and the automated chat replies, which often fail to solve complex issues. In fact, several users mention that resolving problems sometimes took several hours.
Overall, Yesim reviews show what it promises: Fast and flexible connectivity for travel. However, the experience can vary depending on the destination and your English fluency when contacting support.
Best Alternative to Yesim’s eSIM
While Yesim offers convenience and competitive plans, many travellers seek a stronger option with Spanish support and unlimited data. At this point, one of the most recommended alternatives — similar to the Simify eSIM — is Holafly.
Holafly eSIM
The Holafly eSIM is a travel-focused company known for its unlimited data plans in over 200 destinations (like Morocco or Japan). Unlike Yesim, you won’t need to worry about running out of data mid-trip. This peace of mind justifies the price difference between both.
Here are some of the main advantages of Holafly over Yesim:
- Unlimited data in most destinations: Ideal for frequent use of maps, social media, or video calls. If you’d like to know why Holafly often ranks higher, check our comparison Simify vs Holafly.
- 24/7 support in English: A key difference if you need urgent help and don’t speak English.
- Wide compatibility: Works with most iPhone and Android devices.
- Quick activation via QR: You buy online, receive a code by email, and get connected in minutes.
- Broader coverage: Available in more countries, including some where Yesim doesn’t yet operate.
As for prices, Holafly may be slightly more expensive for short-term plans, but having unlimited data makes it more cost-effective in the long run. For example, a 5-day plan for the United States costs around $20,90 (€19,00), while a 15-day plan for Europe costs about $51,70 (€47,00), both with unlimited data. You can check all updated Holafly Plans on their official website.
Therefore, if you want to travel without worrying about data limits and with the confidence of getting support in your language, Holafly is a more reliable option than Yesim.
