The short answer
Budget roughly 1GB per day and you will be fine for maps, messaging, social, photos, and looking things up. Light users get by on half that. Heavy users who stream, post lots of video, or hotspot a laptop should double it. When in doubt, buy a little short and top up, rather than paying for data you never touch.
Spain is easy to stay connected in. Coverage across the cities, the coast, and the islands is strong, so your data almost always works. Trips here tend to run photo and social heavy, so the amount you buy comes down to how many days you are there and how much you post while you are out.

What actually eats your data
A few habits use far more than everything else combined. Manage these and a small plan goes a long way.
Automatic photo backup is the quiet one, and Spain makes it worse because you will shoot and post constantly. If your phone uploads every photo and video to the cloud over cellular, a beach day can cost gigabytes. Set backup to wifi-only before you leave. Video streaming and video calls are the other two heavy hitters. Maps, messaging, and web searches barely register next to them.
Do you need data if hotels have wifi?
Yes, for the part of the day that matters. You are out in the cities and along the coast most of your waking hours, and that is exactly when you need maps, directions, and translation. Coverage in the towns and resort areas is strong, though remote beaches, trails, and boat trips can dip, so download offline maps for those. Buy data for the hours you are out, and let hotel wifi cover the evenings and the big downloads.
Buy a little short, then top up
The most common mistake is overbuying on day one. It is easy to add more data to your eSIM mid-trip if you run low, so there is no reason to pay upfront for a worst-case guess. Start near the typical number for your trip length above, watch your usage for the first day or two, and top up only if you need it.

Common questions
Is 5GB enough for a week in Spain?
For most travelers, yes. A week of maps around the cities, restaurant lookups, messaging, and photos fits in 5GB, especially with hotel wifi in the evenings. If you post a lot of video and photos or hotspot a laptop, plan for more.
How much data do I need for two weeks in Spain?
Around 8 to 12GB for typical use. Two weeks split between cities and the coast at roughly 500MB to 1GB a day lands there. Heavy social and photo users should look at the higher end.
Does the eSIM work on the Balearics and Canary Islands?
Yes, the same plan covers the islands. Coverage in the main towns and resort areas is strong. Some remote beaches, hiking trails, and boat trips can dip, which is location, not a fault with the eSIM. Download offline maps before heading off the beaten path.
Do I need data if my hotel has wifi?
Yes, for the hours you are out. You need maps, translation, and directions while you are exploring cities or moving between beaches, and that is exactly when hotel wifi does you no good. Buy data for the out-and-about hours and let hotel wifi cover the evenings.
What uses the most data while traveling?
Video streaming, video calls, and automatic photo cloud backup are the big three. Spain is very photo and social heavy, so the backup one bites. Set photo backup to wifi-only before your trip and a small plan lasts.
What if I run out partway through the trip?
Top up your existing eSIM rather than buying a whole new one. Start a little smaller than you think and add data if you need it, instead of overbuying on day one.
