HelloRoam -- Highest Composite Score
HelloRoam scores 4.64/5 on our rubric overall for one-week trips, with App 5.0 and Support 5.0 on an iOS and Android app, live chat plus WhatsApp, and a 180-day refund. Its unlimited tier starts at $5 for short stays and scales down by length of stay, a structure built closer to a one-week traveler's math than Holafly's flat $2.99/day rate once the full seven days are added up. Its fixed plans from $3.50/GB also beat Airalo's $4.50/GB for the roughly 11GB an average week of travel needs.
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 an 11GB week at average usage costs more here than on any other fixed-GB competitor, though its 4.9/5 on our rubric Coverage score and regional bundles suit a one-week trip that crosses two or three countries. Its 14-day refund window is the shortest stated figure among the five, worth checking before a week-long plan is bought well ahead of 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
Nomad -- Best Budget Per-GB Rate
Nomad's $3.00/GB rate is the cheapest fixed price in the matrix, making an 11GB week the least expensive option on paper, though its discount concentrates in Southeast and East Asia rather than applying evenly worldwide. Its email-only support window is the thinnest of the five, a real risk if a connectivity issue surfaces mid-week.
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
Holafly -- Best Unlimited Daily Rate
Holafly's $2.99/day unlimited rate totals under $21 across seven days, the highest Pricing score in the matrix (4.8/5) for a trip length short enough that its fair-use throttle rarely triggers more than once. Its 1GB/day hotspot cap on select destinations is a real limit for anyone planning to tether a laptop across a full week.
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
Saily -- Best for Privacy
Saily's $3.99/GB fixed rate prices an 11GB week above HelloRoam's floor but below Airalo's, and its bundled NordVPN covers the full week at no extra charge. Its 30-day refund window comfortably outlasts a one-week trip bought in advance, unlike Airalo's tighter 14-day cutoff.
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

FAQ
One Week eSIM questions, answered
How much data do I need for a one-week trip?
How much data do I need for a one-week trip?
Average usage across the destinations tracked in this comparison's enrichment data runs close to 1.5GB a day, which adds up to roughly 11GB over seven days. That total sits between the common 5GB tier and 10GB tier sold across this comparison's country data, so most one-week travelers size up to the larger of the two.
Which eSIM is cheapest for a 7-day trip?
Which eSIM is cheapest for a 7-day trip?
Nomad's $3.00/GB fixed rate is the lowest in the matrix, the cheapest base price for an 11GB week at average usage. HelloRoam's $3.50/GB floor and Holafly's $2.99/day unlimited rate both beat Airalo's $4.50/GB and Saily's $3.99/GB for a seven-day trip, depending on whether actual daily usage runs high or low.
Is unlimited data worth it for one week?
Is unlimited data worth it for one week?
Often, for a trip this short. Holafly's $2.99/day unlimited rate totals under $21 across seven days and rarely triggers its fair-use throttle at this length, while HelloRoam's $5/day tier scales down by length of stay. A fixed e-sim from Nomad ($3.00/GB) or HelloRoam ($3.50/GB) still costs less for lighter data use.
Which provider has the fastest speeds for a one-week trip?
Which provider has the fastest speeds for a one-week trip?
Airalo and Saily share the highest Network Generation score in the five-provider matrix at 4.4/5 in our comparison matrix. Speed depends more on which local carrier a provider routes through in each destination than on trip length, so a seven-day stay sees the same performance as a single-day one on the same eSIM.
How does HelloRoam compare to Airalo for a one-week trip?
How does HelloRoam compare to Airalo for a one-week trip?
HelloRoam scores 4.64/5 on our rubric overall for one-week trips, with App 5.0 and Support 5.0, and posts fixed plans from $3.50/GB, a dollar cheaper per gigabyte than Airalo's $4.50/GB for the roughly 11GB a one-week trip needs. Airalo leads on Coverage (4.9/5 on this scorecard vs 4.5/5). HelloRoam leads App 5.0 vs Airalo 4.7, an edge that holds on a multi-country week-long itinerary as well.
What is the refund policy if I buy a one-week eSIM in advance?
What is the refund policy if I buy a one-week eSIM in advance?
HelloRoam states a 180-day refund window, matched by Holafly's 180 days, useful for a week-long plan bought well before departure. Nomad and Saily both publish 30 days, and Airalo publishes 14 days.
Which eSIM app is best for tracking a week of data use?
Which eSIM app is best for tracking a week of data use?
