How much data do I need for a trip to Spain?
Quick answers for a trip to Spain, using the same activity rates as our data calculator — then the local gotchas that change real-world use, and the cheapest plans we listed in our Spain guide.
Quick answer: plan size by trip length
Pick the column that matches how you use your phone. Light is maps and messaging; Typical adds social and a little video; Heavy adds streaming and some hotspot. Figures are the plan size we’d buy after the 15% buffer — not a guarantee of your phone’s meter.

What makes data use in Spain different
- Unlimited can be unusually cheap here. Ubigi’s 7‑day unlimited was $18 and 30‑day unlimited $44 when we checked — often beating oversized fixed plans for heavy users.
- Island hops (Balearics, Canaries) — confirm your plan lists the islands, not only mainland Spain.
- EES biometrics at Schengen borders; same arrival‑day planning note as France and Italy.
- City Wi‑Fi is common in cafés, but beach and old‑town stone walls are where mobile data carries maps and rideshare.
Networks named in our guide: Airalo and Ubigi lead on price in our last check; Europe plans if multi-country.

Frequently asked questions
How much data for a week in Barcelona or Madrid?
Typical use lands around 6 GB after the buffer — we round to a 10 GB plan. Nightlife‑heavy social scrolling is the main bump. Full prices in our Spain guide.
Is Ubigi’s unlimited a good deal in Spain?
At $18 for 7 days when we checked, yes for heavy use — it undercut Maya’s global unlimited. Always re‑check the live plan page.
Spain then Portugal — one plan or two?
A Europe regional eSIM usually wins. Confirm both countries are listed and compare against two country plans in our guides.
How does Signal Atlas calculate these numbers?
We use published planning rates (for example Netflix’s SD ≈ 0.7 GB/hr and Spotify Normal ≈ 72 MB/hr), multiply by hours per day and trip length, add a 15% buffer, and round up to a common plan size. Full methodology is on the calculator page.
