Holafly is undoubtedly one of the best-known eSIM providers among travelers. With its promise of unlimited data and global coverage, it attracts many tourists every year.

According to reviews published on Trustpilot, the majority of users say they are satisfied with their experience with Holafly... However, while some users report easy installation and quick setup, many reviews mention problems encountered once on site, including unstable or completely non-existent connectivity in certain destinations.
One point that comes up frequently in negative reviews concerns customer service. Several users explain that they tried to contact support after a malfunction, but did not receive a satisfactory response.
Some mention support that is difficult to reach, or even non-existent, with automated responses that are perceived as unhelpful when a real problem arises abroad. This lack of human and responsive customer service is often seen as a source of frustration, especially when traveling.
On Reddit, opinions about Holafly are more nuanced and often more technical than on traditional review platforms. Most of the discussions found on various subreddits related to travel and eSIMs date back one to two years, but they remain interesting for understanding the strengths and, above all, the structural limitations of the service.
Some users report having used Holafly several times, both in Europe and Southeast Asia, with an overall satisfactory experience: good coverage in major cities, the ability to consume a lot of data (videos, streaming), and a connection that is considered adequate as long as everything is working normally. Holafly is sometimes perceived as more convenient than some cheaper alternatives when you have intensive data usage.
However, several reports highlight significant reliability issues. Users report cases of very severe throttling, even total loss of connection, even when the network signal was good. When this type of problem occurs, the experience deteriorates significantly, as customer support is often considered ineffective or difficult to reach. Some explain that they were unable to contact support at the critical moment, or only received generic responses via a chatbot.

Travel abroad with confidence: no more roaming fees, connection struggles, or unexpected top-ups. With a travel-friendly eSIM, stay connected everywhere, stress-free and surprise-free.
One of the main advantages of the Holafly eSIM is that there is no physical SIM card. It is a 100% digital eSIM that can be installed directly from your phone's settings, eliminating the need for any physical handling or card changes.
Installation is generally quick and easy, via a QR code, on both iPhone and Android devices. Once the eSIM is activated, users can access the internet abroad without having to search for a local SIM card.
Another positive point: the Holafly eSIM works in addition to the physical SIM card already in the phone. This allows you to keep your main number and remain reachable for calls or texts, while using the eSIM solely for data.
Despite these advantages, several significant weaknesses are regularly mentioned in user feedback.
The first concerns prices, which are considered high compared to other eSIM solutions on the market. By way of comparison, in Japan, a 20 GB eSIM plan is available for around €14.80, while a Holafly eSIM for Japan, limited to 7 days, often costs more than €25. For equivalent usage, the price difference is significant, prompting many travelers to turn to more competitive alternatives.
Another major drawback is customer support. Many users report that customer service is unresponsive and difficult to reach when problems arise. When traveling, if the connection isn't working properly, the lack of readily available human support is particularly frustrating. Several reviews mention automated responses, long wait times, and even the inability to get effective help at critical moments.
Finally, connection reliability may vary depending on the country and local partner networks. When everything is working properly, the experience is acceptable, but when there are malfunctions, the lack of support greatly increases user frustration.

Travel abroad with confidence: no more roaming fees, connection struggles, or unexpected top-ups. With a travel-friendly eSIM, stay connected everywhere, stress-free and surprise-free.
Holafly is now one of the best-known eSIMs on the market. Its strong reputation and brand image mean that it is widely distributed and visible to travelers. It is this positioning that partly explains its often higher-than-average prices, particularly for certain destinations.
However, when traveling abroad, the essentials are not limited to purchasing an eSIM. Once there, what travelers are looking for above all else is a reliable connection, a frictionless experience, and, above all, truly responsive customer support in case of problems. However, it is precisely in these areas that Holafly shows its limitations. Numerous user reviews indicate that when the connection does not work as expected, support is difficult to reach or insufficiently effective, which can quickly become problematic when traveling.
In practice, the ideal eSIM for travel must meet several essential criteria:
It is precisely on all these points that certain alternatives to Holafly stand out. Solutions such as **voilà** have been designed to offer a better balance between price, reliability, and support, with more competitive packages, optimal compatibility with everyday use, and truly accessible customer support. In other words, while Holafly may be suitable for its simplicity and reputation, it is not necessarily the best option for ensuring a smooth trip from start to finish.
Discover why this is the preferred alternative for travelers.

To avoid unpleasant surprises once you arrive at your destination, it is best to choose an eSIM from the outset that can meet the actual requirements of your trip: stability, accessibility, and support. It is precisely on these points that Voilà stands out from Holafly.
These plans are designed for everyday use on the go: GPS navigation, reservations, online payments, social media, light streaming, or translation. The goal is simple: a functional and stable connection, without relying on "theoretical" or limited usage.
Unlike solutions that rely primarily on automated responses, voilà offers human support, familiar with travelers' issues: activation, phone compatibility, network quality, or assistance in case of problems on site. When traveling, this responsiveness makes a real difference.
With Voilà, there are no restrictions on everyday applications.
The services most commonly used when traveling function normally:
Regardless of the destination, users retain normal access to their essential services.
These packages are designed to be more consistent in terms of pricing, particularly for destinations such as Japan, where some generic eSIMs charge high rates for limited durations or usage. The cost per GB remains under control, without compromising on reliability.
No need to multiply eSIMs or change solutions during your trip. It works as soon as you land and remains operational throughout your stay, offering a more peaceful and predictable experience.

How does the Holafly eSIM work?
The Holafly eSIM works like a traditional eSIM, just like most eSIM solutions available on the market. An eSIM (embedded SIM) is a virtual SIM card, directly integrated into the phone, which allows you to connect to a mobile network without a physical SIM card.
In practical terms, after purchase, the eSIM is installed directly from the smartphone settings, on both iPhones and Android devices, usually via a QR code or an eSIM profile to be added. Once installed, the eSIM allows you to access mobile Internet abroad using local partner networks, without having to change your SIM card or modify your main number.
As with any eSIM, its operation depends on two essential elements:
Before use, it is therefore essential to check that your device is compatible. You can test your phone's eligibility now using our eSIM simulator.
