Connectivity has evolved over the past few years to become essential for any traveler. As mobile phones have evolved, we're doing more and more tasks using them: from booking our next flight to changing our accommodations at our destination while traveling. Not to mention the possibilities that today's smartphones offer for sharing data and being able to work remotely from our computer.
eSIMs have become the best option for traveling, offering a much more affordable alternative to international roaming with no hidden costs. One of the most interesting providers on the market is ByteSIM, and in this article, we'll tell you everything you need to know about them and, in addition, the best alternative on the market: Blink eSIM. Below, you'll find everything you need to know.

About ByteSIM
ByteSIM is one of the most interesting providers currently on the market. Since its inception, ByteSIM has offered eSIM services to millions of customers around the world, always providing a carefully curated experience that meets the needs of all its customers.
One of the advantages it offers is its global connectivity in more than 200 countries, including China, Japan, Korea, the United States, and Canada, among many other options. The company's DNA is committed to greater freedom and connectivity, offering travelers the best connectivity, regardless of whether they have a longer or shorter trip planned.
As for installation, ByteSIM ensures a very simple and fast process. From selecting the destination and rate to receiving the eSIM, it will only take three minutes.
Main Features of ByteSIM
ByteSIM offers a wide range of options so we can enjoy our trip to the fullest. We have the option of choosing a local eSIM, if we're only visiting one country, or opting for a regional eSIM that covers several countries. This is a very interesting option for those traveling through several countries and want maximum flexibility.
In terms of coverage, it offers coverage in more than 200 countries. The level of coverage will depend on the agreement with the local operator, so 5G is not always guaranteed.
Finally, the company itself assures that it offers a three-minute activation process from the moment we purchase the eSIM until we have the line activated. However, everything depends on the smoothness of the process, and we don't need the help of a support team.
Finally, a very important aspect is that ByteSIM offers data packages based on the country and the number of days you're visiting, as well as unlimited data. Although the latter are more expensive, especially in certain countries, it's a good option for those who don't want to worry about their data usage.
Advantages of ByteSIM
- The installation process is very simple: from the moment you purchase the eSIM to the moment you can use it, it only takes a little over 3 minutes.
- It allows you to use a hotspot: You can share data with your friends and family or your computer.
- It offers unlimited data plans.
Disadvantages of ByteSIM
- The coverage level will depend on local agreements, so you won't always have 5G.
- Support is provided through AI via a chatbot on their website. However, if you need more in-depth help, you'll have to wait until business hours begin.
- For plans with unlimited data, the price is quite high.
- In other users' reviews, we read that many of the complaints have to do with slow technical support.
Blink eSIM: The Best Alternative to ByteSIM
Now that we've seen ByteSIM's strengths and weaknesses, it's time to compare it to Blink eSIM, one of its main alternatives.

The eSIM activation is immediate. That is, from the moment you purchase it until you have the line activated, it only takes a few minutes. Ideally, you should purchase it in your country of residence, since thanks to our Artificial Intelligence, the eSIM detects the country and doesn't incur any charges. It's only activated the moment you land, so it couldn't be simpler.
Conclusion: Is ByteSIM worth it?
ByteSIM is an interesting option for traveling if you want to be sure you'll have internet access on your next trips. However, the fact that they don't guarantee coverage in all countries and that support won't provide in-depth help if you have an issue can be a significant handicap to consider.
Alternatively, we can always rely on Blink eSIM, as they offer unlimited data in more than 190 countries with a daily flat rate of €3 + VAT.
