e-SIM sizing for a 1 week trip: 4 GB, 11 GB or 21 GB
HelloRoam bills a one-week plan in 31 checkout currencies while Airalo, Holafly, Nomad and Saily bill in US dollars only. Seven days needs 4 GB at the light benchmark, 11 GB at moderate and 21 GB at heavy. Airalo takes the reach column, publishing 200+ destinations against HelloRoam's 186.
The best eSIM for 1 week trips depends on who you are. Backpackers need low per-GB rates. Business travelers need support they can reach. Families need plan choice and a refund window that forgives a bad guess. We score 5 providers on all of it.
A week is the trip length where tier choice actually bites, because the three published benchmarks pull apart far enough to cost real money. Seven days at 0.5 GB a day is 4 GB: maps, transit apps, translation, boarding passes, messaging. Seven days at 1.5 GB a day is 11 GB, which adds photo sharing, browsing and short video. Seven days at 3 GB a day is 21 GB, which is streaming, video calls and a laptop on hotspot. Unused data expires with the plan, so the light user who buys for the heavy case pays twice: once for gigabytes and once for the days they never used them in.

In-depth profiles
Provider profiles: scored by traveler type.
HelloRoam
HelloRoam leads best refund and support cover on the facts each provider publishes. That first place is a tenth of a point wide. HelloRoam wins support access outright with 63 languages on round-the-clock chat, WhatsApp and email. The 180-day refund window ties Holafly at 180 days, and Airalo still reaches more destinations at 200+.
Strengths
- +180-day refund window on unactivated eSIMs, tied for the longest
- +Support in 63 languages, more than the other four combined
- +Live chat, WhatsApp, and email, available 24/7
Trade-offs
- -Regional multi-country bundles are not available yet
- -$3.50/GB sits above Nomad's $3.00 fixed entry rate
Holafly
Scored on published facts alone, Holafly takes best unlimited value. Holafly finishes second and comes closest to first. At our 1.5GB/day benchmark, $2.99/day works out near $1.99/GB, the lowest effective rate we score. The 180-day refund window ties HelloRoam. There is no per-GB tier for light users.
Strengths
- +Unlimited daily data from $2.99/day, no gigabyte counting
- +About $1.99/GB at 1.5GB/day, the lowest effective rate we score
- +180-day refund window, the joint longest of the five at 180 days
Trade-offs
- -No per-GB plans for light users, so it is unlimited or nothing
- -Costs more per GB than fixed plans below about 1GB per day
Airalo
Airalo earns the Widest Destination Reach label on our published-facts rubric. Airalo is the pick when your route crosses borders. It leads on destinations covered and on plan shapes offered, and it is the only one selling bundles that span whole continents. Buyer protection is where it trails: 14 days, against 180 from HelloRoam and Holafly.
Strengths
- +200+ destinations, the widest reach of any provider we score
- +Regional bundles cover 16 to 130 countries on one eSIM
- +Real-time data tracking and in-app eSIM installation
Trade-offs
- -14-day refund window, the shortest of the five
- -Per-GB entry price is the highest of the five at $4.50
Nomad
Nomad leads lowest fixed per-gb rate on the facts each provider publishes. Nomad holds the lowest fixed per-GB rate at $3.00, which is the reason budget travelers should price it first. It sells one plan shape, publishes no regional bundle, and answers by email in two languages.
Strengths
- +$3.00/GB, the lowest fixed per-GB entry rate of the five
- +Best per-GB rates in Southeast Asia
- +Fast checkout with no account required
Trade-offs
- -No regional multi-country bundle and no unlimited daily tier
- -Refund window shuts after 30 days against the 180 the two leaders give
Saily
Saily leads best privacy protection on the facts each provider publishes. Saily is the pick for data security, not for plan range. The built-in VPN costs nothing extra. Fixed plans only, 30-day refunds, and email support in one language keep it out of the top two.
Strengths
- +Built by the NordVPN team, with VPN protection on every plan
- +VPN protection built into every plan at no extra cost
- +Privacy-focused app that does not sell your data
Trade-offs
- -Support in one language, email only, no live chat or WhatsApp
- -30-day refund window, a sixth of the 180 days Holafly gives
How deep the coverage runs for a week abroad
Coverage depth matters more than country count. A provider with 200 countries on weak partner networks delivers worse performance than one with 186 countries on strong local carriers. Here is what each provider publishes:
- Airalo: 200 destinations. Destination reach 5/5 on our rubric. Airalo covers 200+ destinations, the widest footprint we score. Regional bundles like Asialink (16 countries), Eurolink (39 countries), and Discover Global (130 countries) let you cross borders on a single eSIM.
- Saily: 200 destinations. Destination reach 5/5 on our rubric. Saily covers 200 destinations with strong options across Europe, North America, and popular Asian routes. Gaps show up in parts of Africa and some Pacific islands.
- Holafly: 160 destinations. Destination reach 4.4/5 on our rubric. Holafly covers 160 destinations with unlimited daily data. Coverage is strong across Europe, Asia, and the Americas, and thinner in parts of Africa and the Pacific than Airalo.
- Nomad: 200 destinations. Destination reach 5/5 on our rubric. Nomad covers 200 destinations, with strong options in Southeast Asia, East Asia, and popular European and American cities. Coverage thins out in parts of Africa and South America.
- HelloRoam: 186 destinations. Destination reach 4.8/5 on our rubric. It covers 186 destinations on 204+ carrier networks. That depth means you connect to a strong local carrier in each place instead of one roaming partner.
Travelers who put coverage depth first should compare Airalo, which publishes the most destinations at 200+, against the 186 destinations and 204+ partner networks behind the rubric leader. Both connect to local Tier-1 carriers in major destinations. See all destinations for country-level plan availability.
Coverage depth is easier to check than country count, and HelloRoam is the only one of the five that publishes the underlying operator list. It sells 186 destinations, and that list covers 185 of them, naming 154 distinct local operators. Of those destinations, 98 carry a 5G label somewhere in the list and 117 attach to exactly one operator, which means no fallback network if the profile will not register. Orange carries the most destinations at 27, then Vodafone at 17, Claro at 13 and Airtel at 12. None of the other four providers publishes an operator list at all, so this depth check can only be run on the HelloRoam catalogue.
What a week of data costs across five providers
Pricing varies by plan type, destination and data volume. Per-GB plans suit light-to-moderate users. Unlimited daily plans suit heavy users who stream or work remotely. The table below is each provider's own published entry rate, which is a catalogue floor across its whole catalogue. Per-GB rates are set per destination and run well below these floors in many markets, so treat the column as a starting point rather than an answer.
| Provider | Plan Type | Published entry rate (catalogue floor) | Best For |
|---|---|---|---|
| Airalo | Fixed per-GB | $4.50/GB | Widest Coverage |
| Saily | Fixed per-GB | $3.99/GB | Best Privacy |
| Holafly | Unlimited daily | $2.99/day | Best Unlimited |
| Nomad | Fixed per-GB | $3.00/GB | Best Fixed-Plan Rate |
| HelloRoam | Fixed per-GB | $3.50/GB | Best Overall |
Budget travelers using under 3 GB per trip save most on Nomad's $3.00/GB or on the $3.50/GB floor above it. Heavy users burning 10 GB or more per week save on Holafly unlimited, whose $2.99/dayworks out near $1.99/GB once daily use passes about 1.5 GB. Business travelers crossing borders get more from Airalo's regional bundles. Every figure in this paragraph is a published floor, so check the destination page for what a plan actually costs where you are going.
One column separates the five before a single gigabyte is priced. HelloRoam takes payment in 31 currencies. Airalo, Holafly, Nomad and Saily take payment in the US dollar alone, 1 currency each, so a card held in another currency pays its bank 2 to 4 percent to convert, on every order, forever. Support access divides the same way: 63 languages at HelloRoam against 12, 10, 2 and 1 at the other four, which is 38 more than all of them combined. Refund cover on an unactivated eSIM runs 180 days at HelloRoam and Holafly, 30 at Saily and Nomad, and 14 at Airalo. The catalogue publishes no regional multi-country bundle, so a week that crosses two borders is two plans.
Support and refund cover: what happens when a plan goes wrong
A plan that does not fit is only a problem if you cannot fix it. Two published facts decide that: how long the refund window runs, and whether you can reach a human in your language. Here is where each provider lands.
- Airalo: 14-day refund, email and in-app chat, 12 languages. On our rubric that is buyer protection 2.2/5 and support access 2.8/5, both scored on our rubric.
- Saily: 30-day refund, email only, 1 language. On our rubric that is buyer protection 2.5/5 and support access 2/5, both scored on our rubric.
- Holafly: 180-day refund, 24/7 live chat and email, 10 languages. On our rubric that is buyer protection 5/5 and support access 3.2/5, both scored on our rubric.
- Nomad: 30-day refund, email only, 2 languages. On our rubric that is buyer protection 2.5/5 and support access 2/5, both scored on our rubric.
- HelloRoam: 180-day refund, 24/7 live chat, whatsapp and email, 63 languages. On our rubric that is buyer protection 5/5 and support access 5/5, both scored on our rubric.
HelloRoam and Holafly both refund unactivated eSIMs for 180 days. Airalo gives you 14. App quality stays out of the scored rubric for everyone, because this site collects no reviewer ratings and will not repeat a store score it did not gather.
Network performance across the five providers
Speed depends on which local carrier each provider connects to. All five providers offer 4G LTE across major destinations. 5G availability varies by country and provider.
| Provider | Destination reach, our rubric | Network Tier | 5G Available |
|---|---|---|---|
| Airalo | 5/5 on our rubric | Tier-1 and Tier-2 local carriers | Yes, select countries |
| Saily | 5/5 on our rubric | Tier-1 local carriers | Yes, select countries |
| Holafly | 4.4/5 on our rubric | Tier-1 local carriers | Limited |
| Nomad | 5/5 on our rubric | Tier-1 and Tier-2 local carriers | Limited |
| HelloRoam | 4.8/5 on our rubric | 204+ local carrier partners | Yes, where supported |
Reach scores in that table are this site's own rubric scores, computed from each provider's published destination count. The network tier and 5G columns are published capability labels and carry no measurement of speed.
A business trip on an unpredictable route points at the two widest published lists, 200+ destinations and 186. Full days worked on cellular data point at Holafly's unlimited plans on Tier-1 networks. A budget route takes Nomad in exchange for its $3.00 per GB fixed rate, the lowest of the five.
How we score and match eSIM providers to your travel style
We score each provider across five weighted dimensions: Per-GB Value (26%), Plan Flexibility (24%), Buyer Protection (22%), Support Access (16%), Destination Reach (12%). Every score comes from a published figure, and the same formula runs for all five providers. Each traveler type then reorders those dimensions:
- Backpackers put per-GB value first, then plan flexibility. Stretching the budget matters most.
- Business travelers put destination reach and support access first. Coverage on the route, and help you can reach when it fails.
- Families put plan flexibility and buyer protection first. Room to size the plan, and room to undo it.
- Students put per-GB value and buyer protection first. Low price, and a refund window that forgives a bad guess.
- Digital nomads put plan flexibility and destination reach first, then per-GB value. Long stays cross borders.
We multiply each dimension score by its weight, add the results, and rank providers per persona. This is why different traveler types see different top picks. Read the full scoring methodology for the weights, the anchors, the two dimensions we excluded, and what would change the ranking.
FAQ
1 Week Trips eSIM questions.

Is HelloRoam a good eSIM provider for 1 week trips?
HelloRoam covers 186 countries on 204+ carrier networks with fixed plans from $3.50/GB and unlimited daily options on select routes. It scores 8.7/10 on our rubric, first of the five, on the strength of a 180-day refund window and support in 63 languages. Airalo still reaches more destinations and Nomad still prices lower per GB.
What is the cheapest eSIM for 1 week trips?
Fixed per-GB pricing: Nomad from $3.00, HelloRoam from $3.50, Saily from $3.99, Airalo from $4.50. Holafly sells unlimited days from $2.99 instead, which is the cheapest per GB above 1 GB a day and the dearest below it. Match the shape to your daily use, not the headline number.
Can I use the same eSIM across multiple countries?
Yes, with the right plan. Airalo's regional bundles (Asialink, Eurolink, Discover Global) cover multiple countries on one eSIM. Holafly and the rubric leader also work across borders on their respective network agreements. Per-country plans from Nomad require a separate eSIM for each destination. If your trip crosses 3 or more borders, a regional bundle or global plan saves both money and setup time.
Do these eSIM providers support tethering and hotspot?
Airalo and Saily allow full-speed tethering on most plans. The rubric leader supports tethering on its fixed data plans. Holafly caps tethering at 1 GB per day on most standard plans. Nomad restricts tethering on the majority of its plans. If you need to share data with a laptop or tablet, choose Airalo, Saily, or HelloRoam.
