Saily is the best-value Spain eSIM for most 7- to 30-day trips in 2026, because its fixed-data plans give you honest high-speed gigabytes with no daily data cap, an uncapped hotspot, and 3% back in credits. Value here is not the lowest sticker price.
It is the most usable data per dollar once you account for throttling, tethering caps, and expiry.
The cheapest headline number often hides the worst deal on a Spain eSIM. An “unlimited” plan that throttles after a daily cap, or a 7-day allowance that expires mid-trip, costs you more than a slightly pricier plan that delivers.
Here are five plans worth your money, ranked by what you truly get across a short break, a two-week holiday, and a month-long stay.

How We Judged Value for 7- to 30-Day Spain Trips
Value comes down to usable high-speed data per dollar, not the number on the buy button. A plan wins when the gigabytes you pay for stay usable at speed for the full length of your trip.
Five criteria separated the plans below from the forgettable:
- Final checkout price and price per usable GB: the total you pay, divided by the high-speed data you can use before any throttle kicks in.
- Validity and activation window: a 7-day clock that starts on purchase is worthless if you buy a week early.
- Daily limits and throttling: “unlimited” plans that slow after a daily cap are not unlimited, and the throttle speed decides whether they still work.
- Hotspot and tethering caps: a 500 MB daily tethering limit is a real cost if you work from a laptop.
- Top-ups and refunds: adding data mid-trip and getting money back on an unused plan protects you from buying wrong.
The 5 Best-Value Spain eSIM Plans in 2026
| # | Provider | Best For | Standout Feature |
| 1 | Saily | Best value for money | Fixed plans, no daily data cap, uncapped hotspot |
| 2 | Nomad | Best per-GB value | Lowest cost per gigabyte on big bundles |
| 3 | Holafly | Quick setup | One flat daily rate, no data counting |
| 4 | Airalo | Easiest first-time setup | Widest brand recognition, uncapped tethering |
| 5 | Orange | Bought direct from a national carrier | Number and network bought direct from Orange, connected on landing |
These prices reflect each provider’s live site as of July 2026. Allowances and prices change often, so confirm the current plan before you buy.
1. Saily: Best value for money
Saily sells eSIM data plans for single countries, regions, and the whole world, all through one app that also blocks ads and malicious sites. Built by Nord Security, the company behind NordVPN, it folds online protection, including 115+ virtual locations, an ad blocker, and web protection, into the same app where you buy the data.
For a value question, the mechanics that matter are simpler: its Spain plans are fixed-data, they do not throttle you on a daily cap, and the hotspot is uncapped.
The numbers back the value case across every trip length. Saily's 20 GB, 30-day plan runs US$22.99 as of July 2026, roughly US$1.15 per gigabyte, and Saily's smaller plans start at US$3.99 for 1 GB over 7 days. Every purchase earns 3% back in Saily credits, top-ups are one tap in the app, and refunds are available if you buy wrong.
Independent reviewers keep landing on the same verdict. Cybernews rates Saily strongly for affordability and security, TechRadar credits its NordVPN-backed reliability, and it holds a 4.7 out of 5 on Trustpilot.
Strengths:
- Fixed-data plans with no daily data cap, so your gigabytes stay at full speed
- Uncapped mobile hotspot, unlike the 500 MB daily tethering limit on some rivals
- 3% back in Saily credits on every purchase, plus mid-trip top-ups and refunds
- 30-day activation window, so you can buy early and it activates automatically on arrival
- Saily Ultra adds unlimited global data for trips where a fixed plan will not stretch far enough
- Saily’s optional voice and SMS add-on gives you a real number for calls and texts alongside your data plan
Drawbacks:
- Saily's standard plans cover 200+ destinations; opt into Saily Ultra for unlimited data and that map narrows to 121+, worth checking if your trip includes a less-traveled stop.
Saily is recommended for: Travelers who want the most usable high-speed data per dollar across a 7- to 30-day Spain trip, with a hotspot they can actually rely on.
2. Nomad: Best per-GB value
Nomad prices its Spain plans aggressively per gigabyte, especially on the bigger bundles frequent travelers buy. A 20 GB, 30-day plan sits near US$20 at the time of writing, and its largest allowances push the cost per gigabyte below almost every mainstream rival. For anyone who cares first about raw price per GB, Nomad is the plan to beat.
Nomad backs the low pricing with a genuinely uncapped hotspot and flexible top-ups, which makes it a real option for laptop work. The catch sits in its “unlimited” tier: those plans deliver a fixed daily high-speed allowance and then throttle to around 1 Mbps, so they are not truly unlimited.
Strengths:
- Among the lowest price per gigabyte on large Spain data bundles
- Full mobile hotspot with no daily tethering cap
- Wide range of allowances and validity periods, from short breaks to year-long plans
Drawbacks:
- “Unlimited” plans throttle after a daily high-speed quota, so read the fine print
- Data-only, with no phone number, security features, or credits-back scheme
Nomad is recommended for: Data-hungry travelers who optimize for the lowest cost per gigabyte and will happily manage a bigger fixed allowance.
3. Holafly: Quick setup
Holafly prices its Spain plans at a flat daily rate rather than by the gigabyte. You pick the number of days, pay a daily rate that drops the longer you stay, and never watch a data meter. For a heavy user on a short single-country trip, that simplicity can genuinely beat a metered plan.
Holafly’s value depends entirely on how hard you use it. A 10-day plan costs around US$36.90 and a 30-day plan around US$74.90, so a light user overpays badly compared to a fixed 5 GB or 10 GB plan. Tethering is also capped at roughly 500 MB per day.
Strengths:
- Truly simple: a flat daily rate with nothing to count or top up
- Daily rate falls the longer your trip, rewarding two-week and month-long stays
- Established brand with 24/7 live chat and easy setup
Drawbacks:
- No small fixed plans, so light users pay far more than they need to
- Hotspot capped near 500 MB per day, a real limit for remote workers
- Data-only, and heavy use can trigger fair-use throttling
Holafly is recommended for: Travelers who want their Spain eSIM up and running in minutes, then a flat rate with nothing to count for the rest of the trip.
Worth noting: Travel now drives eSIM adoption, with a GSMA survey finding 51% of eSIM users first used the technology while traveling and roughly 15% of all travel connectivity now running on eSIMs. [2] Fast growth is exactly why throttling and hotspot terms vary so widely between providers.
4. Airalo - Easiest first-time setup
Airalo runs the largest eSIM marketplace, which makes it the safest choice for first-time users. It offers standard fixed plans for Spain starting at around US$4 for 1 GB, plus regional Europe plans, and its top-tier plan includes uncapped tethering. If brand familiarity and a proven app matter most, Airalo delivers.
Airalo’s value is solid rather than class-leading. Its “unlimited” Spain plans hand you a daily high-speed quota and then throttle, and independent testing has found it on 4G rather than 5G in parts of Spain. The trade-off buys reach: few providers cover as many destinations or have as long a track record.
Strengths:
- The largest and best-known eSIM marketplace, ideal for first-timers
- Uncapped tethering on its higher-tier plans, good for sharing across devices
- Huge range of single-country and regional Europe plans, with easy top-ups
Drawbacks:
- “Unlimited” plans throttle after a daily high-speed cap
- Tested on 4G in parts of Spain, so peak speeds trail 5G rivals
- Standard Spain plans are data-only, with no security features
Airalo is recommended for: First-time eSIM buyers who want the easiest, most familiar setup experience.
5. Orange - Bought direct from a national carrier
Orange sells travel eSIMs bought direct from a national operator, pairing data with European calls, SMS, and an actual phone number. Its Orange Travel (formerly Orange Holiday) Europe plans cover Spain alongside 40-plus countries and include a number tied to a European carrier network. If you want a number and network bought direct from a European carrier, Orange is the pick.
Orange trades pure data value for a number and network bought direct from a national carrier. A 20 GB Europe plan runs near US$49.90, so the cost per usable gigabyte is higher than the plans on this list that skip a phone number. For travelers who need a European carrier number for hotels, bookings, or local services, buying direct from Orange gets you that in a way a home-market SIM cannot.
Strengths:
- Includes a real phone number and calls/SMS across Europe, bought direct from a national operator
- Unrestricted hotspot and broad multi-country European coverage
- Adds data instantly in the app on the same number
Drawbacks:
- Higher price per usable gigabyte than the plans on this list that skip a phone number
- Aimed at Europe-wide use, so it is overkill for a Spain-only data trip
- Calling features are wasted if you only ever use WhatsApp or FaceTime
Orange is recommended for: Travelers who want a number and network bought direct from a national carrier, alongside data across Spain and wider Europe.
Matching Value to Your Trip: Light, Moderate, and Heavy Users
No single plan wins for everyone, so match the plan to how you use data across a 7-day break, a two-week holiday, and a month-long stay.
- Light user on a 7-day break (maps, messaging, the odd photo): Saily’s 1 GB to 5 GB fixed plans are the clear value pick, since you pay only for what you need and nothing throttles.
- Moderate user on a two-week holiday (daily social, some streaming, occasional hotspot): Saily’s 10 GB or 20 GB 30-day plan gives the best usable data per dollar, with an uncapped hotspot and 3% back. Nomad is the alternative if you optimise purely on price per gigabyte.
- Heavy user on a short, single-country trip (all-day streaming, video calls, laptop tethering): Holafly’s flat-rate plan is quick to set up and genuinely wins, as long as you can live with the daily tethering cap.
- Anyone who wants a number bought direct from a national carrier: Orange is the pick for travelers who specifically want that, worth the higher per-GB cost when it matters more than raw data value.
For most travelers on a 7- to 30-day Spain trip, Saily offers the strongest overall value, with rivals winning only in specific corners.
FAQ'S
Saily is the best-value Spain eSIM for most 7- to 30-day trips, because its fixed plans deliver full-speed data with no daily data cap, an uncapped hotspot, and 3% back in credits. Nomad wins on raw price per gigabyte, and Holafly wins for heavy single-country use.
Yes, a travel eSIM is almost always cheaper than carrier roaming in Spain. Roaming from a home network outside the EU can cost many times a local-data eSIM plan, which is why travel is now the biggest driver of eSIM adoption. [1]
Most Spain eSIMs support hotspot sharing, but the caps vary widely. Saily and Nomad allow uncapped tethering, while Holafly limits it to roughly 500 MB per day, so check before relying on it for laptop work.
Yes, if you install it before you fly. Saily plans have a 30-day activation window and activate automatically on arrival, so you set up on home Wi-Fi and land connected without hunting for an airport SIM kiosk.
Yes, because Saily’s fixed plans are pay-as-you-go with no subscription, so an occasional traveler pays only for the single plan they need, skips the roaming bill, and keeps 3% back toward the next trip.
The Bottom Line
Saily is the best-value Spain eSIM for 7- to 30-day trips in 2026, combining fixed plans with no daily data cap, an uncapped hotspot, and 3% back in credits.
The other four each own a corner: Nomad on price per gigabyte, Holafly on quick setup, Airalo on easiest first-time setup, and Orange on buying direct from a national carrier.
Work out whether you are a light, moderate, or heavy user, then match the plan to the trip. For most travelers, Saily is the fastest route to the most usable data per dollar.
