Airalo -- Best Overall Coverage
Airalo rates 8.9/10 overall, the highest composite in this matrix, on the strength of the widest footprint (200+ countries) and the top-rated app (4.8/5 iOS, 4.6/5 Android). Its unlimited tier ships in select markets only, so Spain travelers should confirm a Spain-specific unlimited SKU before assuming its $4.50/GB fixed rate is the only option. The 39-country Eurolink bundle covers Spain for multi-country EU trips.
Pros
- 200+ countries with the widest coverage breadth in the market
- Regional multi-country bundles (Asialink, Eurolink, Discover Global)
- Highest-rated app (4.8/5 iOS, 4.6/5 Android) with real-time data tracking and hourly runtime estimates
- Airmoney cashback rewards (5-10% depending on loyalty tier)
- Established brand since 2019 with proven reliability
Cons
- Per-GB pricing higher than budget alternatives
- Unlimited plans available in select markets only, not all 200+ destinations
- Customer support slower than premium providers (4-6 hour email response)
HelloRoam -- Best Coverage + Value
HelloRoam rates 8.6/10 overall and is one of only two providers in this matrix, alongside Holafly, selling a genuine unlimited plan for Spain: fixed data from $3.50/GB, or an unlimited tier starting at $5 for short stays that scales down proportionally by trip length. Its 204+ carrier partnerships avoid dependence on any single Spanish network. Support runs email-only with a 12-24 hour response window.
Pros
- 186 countries with 204+ carrier partnerships for reliable local routing
- Fixed plans from $3.50/GB across popular destinations
- Unlimited plans from $5 for short stays, scaling by duration
- 31+ local currencies supported at checkout
- 63-language interface for non-English travelers
Cons
- Email-only support with 12-24 hour response times
- Newer brand (launched August 2025) with shorter track record
- App store ratings still building compared to Airalo
Holafly -- Best Unlimited Data
Holafly rates 8.7/10 overall and sells unlimited daily data from $2.99/day globally, against Spain's own tracked $2.52 single-day rate. Its fair-use policy drops speeds to 256 Kbps-1 Mbps once a plan crosses the 2GB daily threshold, and hotspot tethering caps at 1GB/day on select destinations. Holafly's Support score of 4.65/5 leads the matrix, backed by 24/7 chat and a 6-month refund window.
Pros
- Unlimited daily data from $2.99/day with no data caps
- 178+ countries covered including all major destinations
- Simple per-day pricing: know exactly what you pay before you leave
- 6-month refund policy on unused plans
- 24/7 chat support with fast response times
Cons
- Speeds reduce to 256 Kbps-1 Mbps after daily fair use threshold on most plans
- Hotspot tethering limited to 1 GB/day on select destinations
- Not cost-effective for light data users (under 3 GB/trip)
- Fewer countries than Airalo
Saily -- Best for Privacy
Saily rates 8.4/10 overall and bundles NordVPN into every plan at no extra cost, useful for travelers moving between Spanish cellular data and cafe or plaza WiFi. Its lineup is fixed-data only at $3.99/GB; Saily's own cons list confirms no unlimited daily tier exists across its 150-country footprint. Its App score of 4.5/5 trails only Airalo's 4.7 in this matrix.
Pros
- Backed by NordVPN parent company Nord Security with proven privacy infrastructure
- Integrated VPN protection included on every plan at no extra cost
- Clean, privacy-focused app with VPN toggle inside the eSIM interface
- 150 countries with strong European coverage
- 30-day refund policy
Cons
- Email-only support with no live chat or WhatsApp for urgent help
- Fixed data plans only; no unlimited daily tier
- 150 countries, a narrower footprint than Airalo
- 12-24 hour support response times
Nomad -- Best Budget Option
Nomad rates 8.3/10 overall and posts the highest Pricing score in the matrix (4.8/5) on its $3.00/GB fixed floor, but it doesn't sell an unlimited daily plan for Spain or anywhere in its 112-country lineup. Travelers streaming or video-calling daily need Holafly or HelloRoam instead. Nomad's email-only support, at 24-48 hours, is also the slowest of the five.
Pros
- Competitive pricing starting from $3.00/GB in Southeast Asia
- Simple, fast checkout with no account required in many cases
- Lowest per-GB rates for Thailand, Vietnam, South Korea, and Japan
- Plans start at a low entry price for short trips
Cons
- Email-only support with 24-48 hour response times
- Basic app compared to Airalo and Saily
- 112 countries, the narrowest footprint among the five providers
- Limited plan variety in some countries
FAQ
Frequently asked questions about eSIMs for Unlimited eSIM for Spain
Which eSIM has true unlimited data for Spain?
Which eSIM has true unlimited data for Spain?
Holafly and HelloRoam both sell genuine unlimited daily plans for Spain. Airalo offers unlimited in select markets only, not confirmed here. Saily and Nomad sell fixed data exclusively across their full country lineups, with no unlimited option at any volume.
Does Spain's unlimited eSIM throttle speed after a daily cap?
Does Spain's unlimited eSIM throttle speed after a daily cap?
Yes. This comparison tracks a 2GB daily volume threshold for Spain's unlimited tier before providers cut speeds. Holafly's fair-use policy drops speeds to 256 Kbps-1 Mbps once a plan crosses that threshold, workable for messaging and maps but not sustained video streaming.
Can I tether or hotspot with an unlimited eSIM in Spain?
Can I tether or hotspot with an unlimited eSIM in Spain?
Check first. Holafly's own terms list a 1GB/day hotspot tethering cap on select destinations, separate from the main data allowance. HelloRoam and Airalo don't publish a Spain-specific tethering limit, so test hotspot use against the daily fair-use threshold before relying on it for a laptop.
Is a 30-day unlimited plan cheaper per day than a 1-day plan in Spain?
Is a 30-day unlimited plan cheaper per day than a 1-day plan in Spain?
Yes. This comparison's tracked Spain rate runs $2.52 for one day and drops to $2.15 per day on the 30-day tier, an 18% discount. The 3-day and 7-day tiers both work out to $2.41 per day, and the 14-day tier lands at $2.33.
Does an unlimited eSIM work the same in Spain's Canary Islands?
Does an unlimited eSIM work the same in Spain's Canary Islands?
Coverage should carry over since the Canary Islands run on the same national networks as mainland Spain, though enrichment data notes the islands sit in a different time zone (GMT+0 versus mainland CET). None of the five providers in this comparison publish a Canary-specific unlimited rate separate from mainland Spain.
Which eSIM offers the best support for an unlimited-data trip to Spain?
Which eSIM offers the best support for an unlimited-data trip to Spain?
Holafly scores highest on Support in this matrix at 4.65/5, with 24/7 chat. HelloRoam and Saily both score 4.1, running email-only support with 12-24 hour windows. Airalo scores 4.15 with email and in-app chat. Nomad's 3.85 is the lowest, with a 24-48 hour email-only response time.
