What you should know about eSIMs for your trip
What those who have already tried Avlesky are saying
Vanesa Alcaide M.
Lima, Peru
We used the Avelsky eSIM and the experience was excellent. Activation was quick and easy, and the connection worked perfectly throughout the trip.
There were three of us traveling and all three of us used the eSIM without problems: good coverage, stable internet and more than enough speed for maps, social networks and occasional work.
The price was very reasonable for everything it offers, especially compared to roaming or buying a local SIM.
Overall, a very good experience, clear and reliable service. We would definitely use them again for future trips.
Javier M.
Barcelona, Spain
"One of the best eSIMs we've used while traveling. What sets it apart is how easy it is to use and how well it works right out of the box."
The connection is very stable and fast, and the price is very competitive. No complications or strange surprises.
We had a small doubt with the activation and Avelsky support helped us immediately, a friendly and very professional service.
We'll definitely do it again on future trips!
Carla Morata F.
Bogotá, Colombia
"Activating the eSIM was quick and easy, following the steps provided. The line was operational within minutes."
The connection remained stable throughout the trip, with good coverage both in urban areas and while traveling. Speed was sufficient for browsing, maps, social media, and occasional work use.
We had an initial inquiry and support responded quickly and clearly, resolving the issue directly.
Overall, a very good experience. For its quality, stability, and price, it's worth it and I would use it again on future trips.
Juanma Cabanes H.
Berlin, Germany
"Second time using Avelsky eSIM on a trip, and the experience was just as good as the first. Setup was quick and everything worked from the start."
The connection remained stable throughout the trip, which is very reassuring, especially when using maps and needing to be constantly connected.
We had a small doubt at the beginning and the support was attentive and quick, making the whole experience simple and stress-free.
Overall, a very reliable and reasonably priced service. Highly recommended and I will definitely use it again.
Patricia Cocojuela M.
Madrid, Spain
"It's currently the eSIM I use most when I travel. The service is very reliable, works well from the start, and it's clear that it's well designed."
The coverage is excellent, with good speed and stability, and it works well in different environments and with various types of movement. Everything was simple and straightforward.
To nitpick, it would be nice if they offered even more plan or data options, although what they have more than covers most trips.
I'm eager to try it in new destinations, but I'll definitely continue using it on future trips."
Katherine Hopson T.
New York, USA
"Great!!! I used Avelsky during the trip and the experience was very good from the first moment. Activation was quick and everything worked without problems."
Special mention goes to the support team, who were very attentive and friendly, resolving any questions clearly and quickly. That personal touch was greatly appreciated.
The connection was stable at all times, with good speed for everyday use. It's reassuring to know you can count on the service when you need it.
It's no surprise that more and more people are using it; it's great to find such well-managed services. I'll definitely use it again.
Sam Vazquez G.
Mexico City, Mexico
"You arrive in a new country, get off the plane, activate the eSIM, the minutes tick by... and suddenly: perfect connection. Maps loading, messages coming in, everything working. You know the trip is off to a good start."
There's no such thing as bad coverage here: the signal is more stable than home Wi-Fi, the speed gives you more peace of mind than finding a taxi on the first try, and activation is as seamless as when everything works perfectly the first time.
The support… uff, the support is like finding a power outlet at the airport: it doesn't always happen, but when it does, it's greatly appreciated.
In short: if you travel and don't use Avelsky, it's like traveling without internet these days. You can do it… but it doesn't make any sense.
Vanessa Z.
Milan, Italy
"The service is very comprehensive and works very well overall. It's very convenient to use throughout the trip because the connection is stable and doesn't cause any problems."
There is good coverage in different areas and situations, which means you can stay connected without worrying too much.
We always end up using quite a lot of data for maps, networks, and communication, and the performance has been very good.
A small but understandable issue: during peak hours the network can be a little less reliable, but everything else is a 10/10.
