<tbody> <tr><td><strong>TripoSIM</strong></td><td><strong>~$5.50 / 5 GB · 30 days (5G)</strong></td><td>Yes — plus unlimited</td><td>Yes</td><td>Cheapest for Spain, multi-network routing, dedicated Spain city guides</td></tr> <tr><td>Airalo</td><td>~$21 / 7 days (unlimited only)</td><td>No</td><td>Yes</td><td>Unlimited-only, Orange network</td></tr> <tr><td>Holafly</td><td>~$23.90 / 7 days (unlimited only)</td><td>No</td><td>Yes</td><td>Unlimited-only, pricier for light users</td></tr> </tbody>

*Illustrative — always check the live price for your dates.* Because Airalo and Holafly offer only expensive unlimited plans for Spain, a traveler who needs 5–10 GB overpays. TripoSIM offers a right-sized fixed plan (or unlimited if you prefer), so most Bilbao visitors pay far less for the same trip.

How much data do you need in Bilbao, Spain?

• A weekend break (maps, social, photos): 3–5 GB.
• A week with video and heavy sharing: 10–20 GB.
• Hotspot or a longer Basque Country trip: an unlimited-style plan.

TripoSIM Spain plans start around $5.50 for 5 GB / 30 days and $12 for 20 GB / 30 days, validity starting on first use. The same Spain-wide eSIM covers day trips to San Sebastián, Vitoria and the Basque coast.

Frequently asked questions

What is the best eSIM for Bilbao, Spain? A data-only travel eSIM installed before you arrive. TripoSIM is usually the cheapest for Spain — from about $5.50 for 5 GB / 30 days on 5G — versus Airalo's and Holafly's unlimited-only plans at around $21–24 a week. It covers Bilbao and all of Spain.

Is TripoSIM cheaper than Airalo or Holafly for Spain? For most travelers, yes. Airalo and Holafly sell only unlimited plans for Spain (roughly $21–24 a week), while TripoSIM offers right-sized fixed plans from about $5.50 for 5 GB — so unless you truly need unlimited, you pay much less.

Does the eSIM work at the Guggenheim and across the Basque Country? Yes. Spain eSIM plans use the national networks, so the same eSIM works at the Guggenheim, the Casco Viejo, and on day trips to San Sebastián and the Basque coast at 4G/5G speeds.

Will WhatsApp and my number keep working? Yes. The eSIM is data-only and runs beside your normal SIM, so your number, WhatsApp and bank SMS codes keep working.

When does the plan start? On first data use in Spain, not at purchase — so you can install it before you fly with no waste.

Do I need passport registration for a Bilbao eSIM? No. A travel eSIM needs no shop visit or passport registration, unlike a local Spanish SIM — you buy online and install the QR yourself.
