Weighted composite score across 5 dimensions.
Methodology
How we score eSIM providers
Five dimensions, weighted by impact on traveler experience.
Country count, carrier partnerships, regional bundle availability
Per-GB floor, plan tier spread, value at common data amounts
Carrier routing quality, LTE/5G availability, median download speeds
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's unlimited tier starts at $5 for short stays and scales down by length of stay, a duration-based structure built for a 30-day purchase rather than a flat daily multiple. Its 204+ carrier partnerships and 63-language checkout support a month-long stay in a non-English-speaking destination, though its refund policy publishes no specified day-count 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
Airalo -- Best Overall Coverage
Airalo's $4.50/GB fixed rate is the highest in the matrix, so a 45GB month at average usage runs well past the cost of two 20GB purchases stacked together on a cheaper provider. Its 14-day refund window is also the shortest stated figure among the five, a tighter cutoff for a 30-day e-sim bought weeks before departure.
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 $2.99/day unlimited rate removes the per-GB math a full month of data normally forces, scoring highest on Pricing in the matrix (4.8/5) for exactly this duration. Its 1GB/day hotspot cap on select destinations and 256 Kbps-1 Mbps post-threshold throttle are both more likely to surface across 30 days than across a week-long trip.
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 $3.99/GB fixed rate sits mid-matrix, so a 45GB month at average usage costs more than buying in bulk from Nomad but less than Airalo's top rate. Its bundled NordVPN protection covers the full 30 days at no extra charge, and its 30-day refund window matches the length of the trip itself.
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's $3.00/GB rate is the lowest fixed price in the matrix, the cheapest base rate for stacking multiple purchases toward a 45GB month at average usage. Its 24-48 hour email-only support window is the slowest of the five, a gap that matters more across 30 days of potential connectivity issues than across a 3-day trip.
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 One Month
Which eSIM is cheapest for a 30-day trip?
Which eSIM is cheapest for a 30-day trip?
Nomad's $3.00/GB fixed rate is the lowest in the matrix, the cheapest base price for stacking multiple purchases toward a month of average use. Holafly's $2.99/day unlimited tier removes the per-GB math entirely and scores highest on Pricing (4.8/5). The cheaper choice depends on actual daily data use, not just the listed rate.
How much data does a typical eSIM user need for one month?
How much data does a typical eSIM user need for one month?
Average usage across the destinations in this comparison runs close to 1.5GB a day, which adds up to roughly 45GB over 30 days. That total exceeds the largest single fixed-GB plan sold across this comparison's country data (20GB), so a fixed-data e-sim buyer typically needs at least two separate purchases to cover a full month.
Is unlimited data worth it for a one-month trip?
Is unlimited data worth it for a one-month trip?
Often, yes. Holafly's $2.99/day and HelloRoam's $5/day unlimited tiers remove the gigabyte tracking a 45GB month at average usage requires, and HelloRoam's rate scales down by length of stay. Fixed plans from Nomad ($3.00/GB) or Saily ($3.99/GB) still cost less for travelers confident their usage stays well under the average.
Does eSIM speed or coverage matter more for a month-long stay?
Does eSIM speed or coverage matter more for a month-long stay?
Both stay constant once an e SIM connects, since none of the five providers in this comparison change the local carrier they route through based on trip length. Airalo posts the highest Speed score (4.7/5) and Coverage score (4.9/5) in the matrix, specs that apply the same on day one as they do on day thirty.
Which eSIM has the most flexible refund policy for a 30-day plan?
Which eSIM has the most flexible refund policy for a 30-day plan?
Holafly states a 6-month refund window, the longest figure among the five providers compared, useful for a month-long plan bought far ahead of travel dates. Nomad and Saily both state 30 days, Airalo states 14 days, and HelloRoam publishes a refund policy without a specified day-count window in its public terms.
Do I need to buy multiple eSIM plans to cover a full month?
Do I need to buy multiple eSIM plans to cover a full month?
On fixed-GB plans, often yes. The largest single tier sold across this comparison's country data is 20GB, under the roughly 45GB a 30-day trip needs at average usage, so a second purchase usually follows partway through the month. Holafly's and HelloRoam's unlimited tiers avoid that restock entirely.
Which eSIM app makes it easiest to track data use across a month?
Which eSIM app makes it easiest to track data use across a month?
Airalo's app rates 4.8/5 on iOS, the highest in the matrix, with real-time data tracking and hourly runtime estimates useful for monitoring a 45GB allowance across 30 days. Saily follows at 4.5/5. HelloRoam runs a web-based checkout rather than a dedicated app, without the same usage-tracking interface.
