Best eSIM for Spain: Comparing Plans, Prices & Features

This blog post was sponsored by Saily. All opinions are my own.

If you’re visiting Spain from anywhere outside the EU, staying connected without racking up roaming charges can be a challenge. An eSIM is one of the easiest and most affordable ways to avoid the hassle of buying a local SIM card or relying on dodgy hotel Wi-Fi.

As someone based in the EU, I’m lucky enough to avoid roaming fees here, but I know that’s not the case for many of you. That’s why I’ve spent hours researching Spain’s top eSIM options to help you find the best deals, most reliable networks, and simplest setups.

Whether you’re heading to Barcelona, Madrid, or off-the-beaten-path villages, this guide will walk you through the best eSIMs for Spain, with real pros and cons, current pricing, and practical tips to make sure you stay connected with ease.

1. Saily: Best for Security and Ad-Free Browsing

Best for: Travelers who want extra privacy and built-in protection

If you want more than just data while traveling in Spain, Saily is a great choice. Created by the team behind NordVPN, Saily also offers built-in ad blocking, web protection, and even a virtual location feature.

This is especially helpful for accessing websites in your own language or watching content that might be region-restricted. Plus, the ad blocker saves you data by stopping trackers and pop-ups before they load.

In Spain, Saily offers affordable data plans, including 10 GB for $15.99 and unlimited plans starting at $48.99 for 15 days. This price is only just slightly higher than other eSIM providers but offers so much more protection.

2. Ubigi: Best for Super Cheap Data in Spain

Best for: Travelers who just need affordable data without extras

If you’re looking for the cheapest way to get online in Spain, it’s hard to beat Ubigi. At just $12 for 10 GB, it’s one of the most budget-friendly options out there, perfect for shorter trips or travelers who mostly use data for maps, messages, and browsing.

Ubigi keeps things simple: there are no fancy features, no unlimited texting apps, and no built-in security tools. But it delivers fast coverage throughout Spain without breaking the bank.

They also offer short-term unlimited plans starting at $18 for 7 days, which can be great value if you’re traveling during a data-heavy week.

3. Holafly: Best for Unlimited Data

Best for: Travelers who want unlimited data without tracking usage

If you don’t want to worry about running out of data while traveling in Spain, Holafly is a great option.

Unlike most providers, Holafly focuses on unlimited data plans, making it a great choice if you rely heavily on Google Maps, social media, or streaming during your trip.

It’s also quite unique in that you can choose the exact number of days you need, rather than being limited to fixed durations like 7, 10, or 15 days.

This can be especially helpful if you’re moving between cities or staying longer, since you won’t need to constantly check your usage or top up your plan.

4. aloSIM: Best for Travelers Who Want a Phone Number Too

Best for: Those who need both mobile data and a local/international number

If you want the convenience of mobile data plus the ability to make calls or send texts, aloSIM is one of the few travel eSIMs that delivers both.

When you buy any aloSIM plan, you get access to a free international phone number, which can be a huge perk if you need to make bookings, confirm reservations, or receive SMS verification codes while in Spain.

aloSIM’s data prices are slightly higher than the lowest-budget options, $18 for 10 GB, but it might be worth it if you need a phone number.

5. Roamless: Best for Flexible Travel Plans

Best for: Travelers who want country-specific or global coverage in one place

Roamless stands out with its dual plan options: choose a fixed plan for Spain (just $14.95 for 10 GB) if you’re staying in one country, or go with a flexible plan that works globally.

The flexible option is ideal if you’re also visiting other countries in Europe, and it doesn’t expire, so any leftover data stays in your account.

Unlike most eSIMs, Roamless also offers low-cost international calls and SMS through their flexible plans, only $0.01/min, which is a great deal if you don’t want to rely on Wi-Fi calls or messaging apps.

6. Jetpac: Best for Perks & Post-Data Access

Best for: Travelers who want extras like lounge access and essential apps after data runs out

While Jetpac‘s Spain data plans are reasonably priced ($15 for 10 GB, or $41.99 for 15 days of unlimited data), what really sets Jetpac apart are the perks.

If your plan runs out, you’ll still have free access to essential apps like Google Maps, WhatsApp, Uber, and Grab, as long as you originally purchased at least 3 GB of data. That’s incredibly helpful when you’re out and about and suddenly run low on data.

Another standout perk? Airport lounge access if your flight is delayed, or, if you upgrade, you can get access every time you fly, not just when there’s a delay.

Is Your Phone eSIM-Compatible and Unlocked?

Before you can use an eSIM in Spain (or anywhere else), make sure your phone checks two boxes:

1. eSIM Support

Most newer smartphones, like iPhones from the XS model onward, Samsung Galaxy S20 and up, Google Pixel 3 and newer, support eSIMs.

Quick tip: Just search for “eSIM” in your phone’s settings to see if you have the option to add one.

2. Carrier Unlocked

Your phone must also be carrier-unlocked, meaning it’s not restricted to one mobile network.

• On iPhones: Go to Settings > General > About, then look for Network Provider Lock
• On Android: Try Settings > Connections or Network & Internet > Mobile Networks or SIM > Choose network or Automatically select network and check if you see more than one network listed, or contact your carrier to check.
