The best unlimited travel eSIM is Holafly at $2.99/day across 178 countries. That is the lowest published daily rate of the five, and it is why Holafly wins this page. HelloRoam is second: it sells unlimited daily plans as well as 3GB to 20GB fixed plans across 186 destinations, and it bills in 31 currencies. Airalo sells unlimited in select markets only.
All five major travel eSIM providers are scored here for heavy data use: streaming, video calls, tethering, and full-day browsing. Two of them sell unlimited daily data outright, and a third sells it in select markets. The order below is the price of that unlimited day, not the overall rubric order.
Unlimited daily plans start from $2.99/day and scale by trip length and destination. Heavy streamers and remote workers burning 10+ GB/week save significantly compared to per-GB alternatives.
Fixed data plans range from 3GB to 20GB with per-GB rates starting at $3.50. Unlimited daily plans offer an alternative for heavy users. Localized pricing in 31+ currencies means travelers pay in familiar denominations without hidden conversion markups.
Plans start from $4.50 for entry-level packages. Regional bundles offer strong value for multi-country trips. Airmoney cashback rewards (5-10%) reduce effective cost for repeat buyers.
Plans start from $3.99/GB across popular destinations. The privacy premium is built in: VPN protection is included on every plan at no additional cost.
Nomad's pricing shines in Southeast Asia. A 5GB Thailand plan costs $6.99. In Vietnam, 3GB costs $4.50. The best rates are in budget-friendly Asian destinations.

Most travelers do not need unlimited data. A week of Google Maps, messaging, and light social media burns through two to three gigabytes at most. A $5 fixed plan handles that with room to spare. Unlimited only starts to pay for itself when your daily consumption regularly exceeds one gigabyte.
Three traveler profiles benefit the most. Streamers who watch Netflix or YouTube daily use 1 to 3 GB per hour of video. A single evening of streaming can wipe out a small fixed plan. Remote workers on video calls burn 1 to 2 GB per hour on Zoom or Google Meet. A full workday of calls adds up fast. Tethering users who share their phone connection with a laptop or tablet double their consumption.
If any of those describe your trip, Holafly at $2.99/day removes the mental overhead of tracking gigabytes. For everyone else, a fixed plan from Nomad or HelloRoam costs less and does the job.
“Unlimited” does not mean “unthrottled.” Holafly applies a fair-use policy that reduces speeds after you exceed a daily data threshold. The exact threshold varies by country and carrier partner, but the pattern is consistent across destinations.
Once the threshold is crossed, Holafly steps the connection down for the rest of the day. Text-based apps, messaging, email, and basic maps keep working at the reduced tier. Video buffers, and streaming stops being comfortable.
The throttle resets each day at midnight local time. Holafly publishes the fair-use threshold per destination rather than a single global figure, and it routes through NTT docomo in Japan, EE in the UK and T-Mobile in the US. Most travelers never reach it. Heavy streamers will, by mid-afternoon on an intensive day.
A fixed plan avoids this entirely. Saily publishes fixed data plans only, Nomad sells fixed data from $3.00/GB, and most Airalo plans are fixed buckets between 1GB and 20GB. You get full speed until your data runs out, then you stop. No throttling, no reduced-speed mode. You simply buy more data or go without.
Unlimited sounds like the obvious choice, but the numbers tell a more specific story. Whether Holafly saves you money depends on how long you travel and how much data you use.
| Trip length | Holafly (unlimited) | Airalo (10GB) | Nomad (5GB) | Winner |
|---|---|---|---|---|
| 7 days | ~$22 | ~$16 | ~$9 | Nomad (light users) |
| 14 days | ~$42 | ~$32 | ~$18 | Holafly (heavy users) |
| 30 days | ~$69 | ~$45 | ~$30 | Holafly (heavy users) |
For trips under a week, fixed plans almost always win on price. A light user spending $9 on Nomad gets more value than paying $22 for unlimited data they never fully use. The crossover happens around the 10-day mark for heavy users: if you burn through more than 1 GB daily, Holafly's flat daily rate starts to undercut multiple fixed plan purchases and top-ups.
The 30-day comparison is where unlimited earns its keep. A heavy user on Airalo might buy two 10GB plans ($45+) and still run short. Holafly's $69/month removes the guesswork entirely.
Tethering is the deal-breaker for many remote workers. Sharing your phone's eSIM connection with a laptop or tablet is the only way to get online in places without reliable Wi-Fi.
Holafly allows tethering on its unlimited plans, but caps hotspot usage at roughly 1 GB per day. That is enough for email, Slack, light browsing, and document editing. It is not enough for extended video calls or large file transfers over hotspot.
Airalo, Saily, and Nomad all allow full tethering with no separate hotspot cap. The data you buy is the data you use, whether on your phone or shared over hotspot. If you plan to tether heavily, a 10GB or 20GB Airalo plan gives you full-speed hotspot without daily limits.
Our recommendation: choose Holafly if you tether occasionally and want unlimited on-device data. Choose Airalo if tethering is your primary use case and you need reliable hotspot for work.
