HelloRoam -- Highest Composite Score
HelloRoam scores 4.64/5 on our rubric overall, with App 5.0/5 and Support 5.0/5. Its unlimited tier starts from $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 iOS and Android app support a month-long stay in a non-English-speaking destination, and its refund policy states 180 days on unactivated plans.
Dimension scores, 0-5 on our rubric
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
- iOS and Android app with in-app top-up, add-destination, and usage alerts
- Live chat, WhatsApp, and email support, including real-time channels
- 31+ local currencies supported at checkout
- 63-language interface for non-English travelers
Cons
- Newer brand (launched August 2025) with shorter track record
- 186 countries, behind Airalo's 200+ catalogue
Airalo -- Widest Coverage Catalogue
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.
Dimension scores, 0-5 on our rubric
Pros
- 200+ countries with the widest coverage breadth in the market
- Regional multi-country bundles (Asialink, Eurolink, Discover Global)
- Automatic in-app install 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
- No live chat or WhatsApp channel: support runs on email and in-app messaging
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.
Dimension scores, 0-5 on our rubric
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
- 200 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
- 200 countries, just behind Airalo's 200-plus
Holafly -- Best Unlimited Daily Rate
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 a heavily reduced speed post-threshold throttle are both more likely to surface across 30 days than across a week-long trip.
Dimension scores, 0-5 on our rubric
Pros
- Unlimited daily data from $2.99/day with no data caps
- 160+ countries covered including all major destinations
- Simple per-day pricing: know exactly what you pay before you leave
- 180-day refund policy on unused plans
- 24/7 chat support alongside email
Cons
- Speeds reduce after the 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
Nomad -- Best Budget Per-GB Rate
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 email-only support window is the thinnest of the five, a gap that matters more across 30 days of potential connectivity issues than across a 3-day trip.
Dimension scores, 0-5 on our rubric
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 no live chat, WhatsApp, or phone channel
- Basic app compared to Airalo and Saily
- 200 countries, behind only Airalo among the five providers
- Limited plan variety in some countries

FAQ
One Month eSIM questions, answered
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 in our comparison matrix). 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. HelloRoam's unlimited tier from $5 and Holafly's $2.99/day 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 joint-highest Network Generation score (4.4/5) and Coverage score (4.9/5) in the matrix, specs that apply the same on day one as they do on day thirty. HelloRoam still leads the 2026 composite at 4.64/5 on our 2026 rubric.
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?
HelloRoam states a 180-day refund window, matched only by Holafly's 180 days, useful for a month-long plan bought far ahead of travel dates. Nomad and Saily both state 30 days, and Airalo states 14 days.
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. HelloRoam's and Holafly'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?
HelloRoam scores 5.0/5 on our 2026 rubric on App with an iOS and Android app that includes usage alerts useful for monitoring a 45GB allowance across 30 days. Airalo's app rates 4.7/5 on our 2026 rubric, with real-time data tracking and hourly runtime estimates. Saily follows at 4.5/5 in our comparison matrix.
