Data Plans and Prices
Limited data plans: You choose a data plan with a certain data volume and validity (e.g. 10 GB valid for 30 days). You can choose these plans according to your surfing behavior. Limited plans are cheaper than unlimited plans
Unlimited data plans: Here you can surf as much as you like. The price for unlimited plans depends on how long they are valid for. The good thing is that you don’t have to worry about usage here.
Pay-as-you-go tariff: You only pay for the GB you use. At Yesim, these tariffs are called Pay&Fly
Prepaid data tariffs (limited data volume) – data packages for Laos
- 3 GB for 7 days = €9.00
- 5 GB for 15 days = €12.00
- 10 GB for 30 days = € 19.00
- 20 GB for 30 days = € 29.00
Unlimited data volume (∞ GB) – data packages for Laos
- Unlimited for 1 day = €7.00
- Unlimited for 7 days = €30.00
- Unlimited for 15 days = €50.00
- Unlimited for 30 days = 62,00 €
Pay & Fly (PRO 1 GB) )Pay-as-you-go)
- 1 GB for 7 days (Turkey) = € 3.00
- 1 GB for 7 days (Germany) = € 3.50
- 1 GB for 7 days (China) = € 4.50
Pay & Fly from = 0,92 € / GB
These are a few examples of how much 1 GB costs with the Pay & Fly tariffs, depending on the country of travel
There are country-specific tariffs, regional data plans, for example for a specific continent or part of a continent (South East Asia) and worldwide data plans. What is unique in our experience so far is that Yesim also offers data plans for individual cities. For us, this makes Yesim the best eSIM for a city trip.
Country plans: Limited, unlimited or pay-as-you-go tariffs valid in a country of your choice
Regional: Your data is valid in all countries of a continent. Yesim offers a data plan for Europe, for example, which includes 33 countries. However, there are also tariffs for South East Asia (8 countries) or South America (12 countries) which are only valid in part of a continent.
Worldwide: As the name suggests, these tariffs apply worldwide. First of all, you can choose between a pay-as-you-go (170+ countries), the global package (80+ countries) or the global Plus package.
These are then divided into limited and unlimited data plans.
Cities: Here you have limited and unlimited eSIM data plans available, each of which relates to just one city.

Network Coverage and Speed
Network coverage – Yesim eSIM Review
Network coverage mainly depends on which local network is used in the respective country, as Yesim does not have its own network. In the USA, for example, the networks of Verizon, T-Mobile, AT&T and other providers are used.
The good thing about Yesim is that, compared to many other providers, you are always connected to the best and fastest network. For example, if a provider offers 5G and a stronger signal, you will automatically be connected to the corresponding network.
In our experience, many other providers only use one or two networks. This means you are guaranteed the best network coverage and fastest connection with Yesim.
Speed – Yesim eSIM Review
The speed also depends on the local network. In many countries, such as Japan and the USA, the 5G network is already very well developed and fast Internet connections are possible there. In other countries, such as Colombia or some Southeast Asian countries, the 4G network is currently still available.
In our review, we found Yesim’s network coverage and speed to be very good!
Calls/SMS and Hotspot Usage - Yesim eSIM Review
Yesim has mainly focused on data-only tariffs, so it is not possible to make classic phone calls or send and receive text messages.
You can make calls via common apps such as Whatsapp, FaceTime, zoom etc.
Virtual numbers – Yesim eSIM Review
Yesim offers a special service for companies, where virtual phone numbers are assigned for certain countries. An additional virtual number costs around €3 per month and is used to receive text messages, mainly to enable verification and to be able to use WhatsApp via a local number. However, calls cannot be made via such a number.
Mobile hotspot
When choosing an eSIM, it is important to consider whether hotspot use is permitted, as there are some providers who limit this, especially for unlimited tariffs. This is not the case with Yesim. The hotspot can be used without restrictions. This means you can also connect to your laptop or other devices and use your data. However, you should be aware that more data is consumed and you
To summarize:
- Phone calls & text messages: Only via apps such as WhatsApp or the home contract, the same applies to sending and receiving text messages
- Virtual numbers: For some countries, companies can obtain virtual numbers that enable verification. It is not possible to make calls with these numbers, but it is possible to send and receive text messages.
- Hotspot/Tethering: There are no restrictions on hotspot use with Yesim, so you can easily connect other devices to your smartphone and use your mobile hotspot.
Payment Options in the Yesim app
Payments are quick and easy and are all made directly via the Yesim app. Common payment methods such as credit card (Visa, Mastercard etc.), PayPal, Apple Pay/Google Pay or you can use the ycoins received via the loyalty program, which you can receive by referring friends.
Choose the currencies Euro, US Dollar or British Pound. If you buy a pay-as-you-go tariff, you can set up an automatic top-up (auto-reload), where a predetermined amount is automatically added as soon as the balance falls below a certain threshold.

Conclusion: Yesim eSIM Review & Discount Code
We think Yesim is one of the best eSIM solutions in the world for mobile internet. There is a very extensive selection of data plans, so everyone should find a suitable plan according to his/her consumption behavior. There are limited data plans at lower prices and unlimited tariffs for frequent surfers. In addition, data volumes can be selected for countries, regions, cities or worldwide.
Pay-as-you-go tariffs and virtual numbers are not standard with most providers. Simple “one-click” installation is also not available from every provider.
The prices are comparatively low, installation is simple and there are additional offers such as a loyalty program, discount vouchers and a referral program.
Both the iOS app and the Android app are user-friendly and clearly laid out.
One of the most important points is the very good network coverage that Yesim makes possible by using various local mobile networks. After our test, we can say that Yesim is one of the best eSIMs on the market and therefore gets a clear recommendation to buy.
