What this tool does
In 2026 you have three real options: (1) buy a Spanish physical SIM (Vodafone, Orange, Movistar — €10–25), (2) buy an international eSIM before you fly (Airalo, Holafly, Nomad — €5–30), (3) roam with your home provider (€2–15/day, usually poor value). The right pick depends on trip length, data appetite, and whether you need a Spanish number for restaurant reservations and WhatsApp calls.
This calculator gives the optimal option for your situation.
The 2026 SIM landscape
- Spanish prepaid (Movistar, Vodafone, Orange): €10–25 for 30 days, 5–30GB. Must buy at the airport, official shop, or tobacco store (estanco). Requires passport registration.
- International eSIM (Airalo, Holafly, Nomad): Buy before flying, scan QR code, instant activation. €5–30 for 5–30GB. No Spanish number.
- Home provider roaming: Most EU providers (Vodafone UK, Orange FR, Telekom DE) include Spain in EU roaming. Outside EU: usually €2–10/day.
Frequently asked questions
Is eSIM better than physical SIM?
For most travellers in 2026, yes. eSIMs activate instantly, you keep your home SIM for calls, and you can switch providers easily. Only choose physical if your phone doesn't support eSIM or if you need a Spanish number.
Does Spain cover all of the country with mobile data?
Cities and main roads: yes, 4G/5G. Rural areas: usually 4G but slower. Mountain hiking: download offline maps (Google, Maps.me, OsmAnd) before you go. Remote Picos de Europa: 2G or no signal.
Can I buy a SIM at the airport?
Yes — Madrid, Barcelona, Málaga and Palma airports have operator kiosks after arrivals. Slightly overpriced (€5 extra). Better: eSIM before you fly.
Do I need a Spanish phone number for WhatsApp?
No — WhatsApp works with any number. Spanish restaurants often call/text to confirm reservations. If you'll be making Spanish restaurant reservations yourself by phone, a Spanish number helps.
Limitations
Prices and data allowances change frequently. Always verify on the operator's site. eSIM support depends on phone model — older Androids may not work.
