At Xataka we travel a lot to cover presentations or learn about new products, often outside of Spain, and from our own experience we have long been running away from unreliable public Wi-Fi networks or roaming (some scary bills have already reached us). Instead, we pull eSIM services like Sailywhich from now on is included as one of the advantages of Xataka Xtra.
From the creators of NordVPN: a secure and well-functioning eSIM
We decided to try Saily because it has been developed by the team behind NordVPN, which for us is one of the best vpn. They have mixed the privacy and security philosophy that they use at Nord and combined it with data packs at a good price. Some of its main features:
- Instant connection: If you have ever had to stop at an airport to buy a physical SIM card, you will know how annoying it is. With the Saily app, you choose your destination (there are more than 200 available), you sign up for the plan and you already have data before you even get off the plane.
- Emphasis on security: Unlike hotel Wi-Fi, where you share a network with strangers and expose yourself to data theft and hacking, using Saily’s eSIM is like navigating a private tunnel. It connects directly to cell towers, so your traffic is shielded by professional mobile security standards. In addition, Saily includes a ‘shield’ in its interface that blocks ads and dangerous websites before they reach your mobile phone, very useful for when you don’t know the pages in another language that you usually visit when you are abroad.
- No surprises: Saily is prepaid. You choose how many GB you need and how much you want to spend. There are no contracts or fine print, so you will avoid any scares when you return home.

Why do we like Saily?
You can imagine: at Xataka we have tested many eSIMs and other connectivity solutions, but what we like most about Saily is its simplicity:
- One-click installation: No more configuring complicated APNs or removing and inserting cards with a clip. It is 100% digital.
- Almost global coverage: Whether you are going to Thailand, Brazil or Canada, Saily offers plans to more than 200 international destinations with very reasonable prices.
- 24/7 Support: If you have any problem during your trip, the support team responds quickly both by chat and email.
One more advantage for being from Xataka Xtra
If you are part of Xataka Xtrayou will get a 10% discount on any new international eSIM with Saily.
Whether you have a getaway planned or a business trip, this eSIM is one of the best we have tested and thanks to Xataka Xtra you can get it even cheaper.
