Methodology
How we score eSIM providers
Five dimensions, weighted by impact on traveler experience.

Store ratings, installation flow, data tracking, interface quality
Channel availability, response time, refund policy
All scores are editorial assessments based on verified data. Pricing checked weekly. See our full scoring methodology for details.
HelloRoam -- Best Coverage + Value
HelloRoam publishes a refund policy without a specified day-count window, the only provider among the five without a stated number in its public terms. Its $3.50/GB prepaid floor and $5/day unlimited tier still undercut Saily and Airalo on rate, with the refund-window gap as the main differentiator on this spec.
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
Airalo -- Best Overall Coverage
Airalo's 14-day refund window is the shortest stated figure among the five providers compared, a real constraint for a prepaid plan bought months ahead of a trip. Its 200-country footprint and 5.0 Coverage score, the highest in the matrix, remain the widest despite the shorter refund policy.
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)
Holafly -- Best Unlimited Data
Holafly's stated 6-month refund window is the longest of the providers that publish a specific number, a meaningful spec for a prepaid purchase made well ahead of a trip's actual dates. Its Pricing score of 4.8 sits second in the matrix behind Nomad's 4.9, both ahead of Airalo, HelloRoam, and Saily.
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's 30-day refund window matches Nomad's and sits well below Holafly's stated 6-month policy, though Saily folds VPN access into the same prepaid purchase at no separate charge. Its $3.99/GB rate prices a prepaid plan above Nomad's $3.00/GB but below Airalo's $4.50/GB.
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 scores highest on Pricing in the matrix at 4.9 out of 5 and does not require an account for many purchases, the fastest checkout among the five providers compared. Its 30-day refund window matches Saily's but trails Holafly's stated 6-month policy by a wide margin.
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

Which eSIM scores highest on pricing for prepaid plans?
Which eSIM scores highest on pricing for prepaid plans?
Nomad scores highest on the Pricing dimension in the matrix at 4.9 out of 5, with its $3.00/GB fixed rate the lowest floor among the five providers. Holafly follows at 4.8 on a $2.99/day unlimited structure. HelloRoam, Airalo, and Saily score 4.5, 4.3, and 4.2 on the same dimension.

Yes, all five providers publish a refund policy for unused, unactivated plans. Holafly states a 6-month window, the longest figure compared, Nomad and Saily state 30 days, and Airalo states 14 days. HelloRoam lists a refund policy without a specified day-count window in its public terms.
Is a prepaid eSIM cheaper than a prepaid physical SIM card bought locally?
Is a prepaid eSIM cheaper than a prepaid physical SIM card bought locally?
A prepaid e SIM skips the local ID, credit check, and airport kiosk line a prepaid physical SIM often requires, though per-GB rates vary by destination on both formats. The five providers here price prepaid data from $2.99/day to $4.50/GB, a range worth checking against local prepaid SIM pricing.
Do longer prepaid unlimited eSIM plans cost less per day than shorter ones?
Do longer prepaid unlimited eSIM plans cost less per day than shorter ones?
Yes, on the two unlimited tiers in this comparison. Holafly and HelloRoam both discount multi-day unlimited blocks from a 1-day baseline rather than pricing every day flat. Fixed-GB plans from Airalo, Saily, and Nomad price by data volume instead, so the same per-day discount pattern does not apply.
