The best unlimited travel eSIM is Holafly at $2.99/day across 178 countries. No gigabyte cap, no per-MB charges. Airalo tops out at 20GB fixed plans but offers wider coverage (200+ countries). Only Holafly sells true unlimited data.
We tested all four major travel eSIM providers for heavy data use: streaming, video calls, tethering, and full-day browsing. Only one offers genuinely unlimited data. Here is how they rank.
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.
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 Airalo or Nomad 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 kicks in, speeds drop to between 256 Kbps and 1 Mbps. At 256 Kbps, text-based apps, messaging, email, and basic maps still work. Standard-definition video buffers frequently. At 1 Mbps, low-quality streaming is possible but not comfortable.
The throttle resets each day at midnight local time. In our testing across Japan (NTT Docomo), the UK (EE), and the US (T-Mobile), the fair-use cap allowed several gigabytes of full-speed data before throttling engaged. For most travelers, the cap is high enough that you never notice it. Heavy streamers will hit it by mid-afternoon on intensive days.
Airalo, Saily, and Nomad avoid this issue entirely because their plans are fixed. 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.
