Holafly eSIM plans and prices
Holafly sells one kind of plan: unlimited data, priced by the number of days. Here is what it costs for Japan, its Europe plan and Italy, three trips where it often comes up.
| Plan | Japan | Europe | Italy |
|---|---|---|---|
| Unlimited, 3 days | $11.90 | Not offered | $11.90 |
| Unlimited, 5 days | $20.50 | Not offered | $17.50 |
| Unlimited, 7 days | $27.50 | $27.50 | $23.90 |
| Unlimited, 10 days | $36.50 | $37.50 | $32.90 |
| Unlimited, 15 days | $50.50 | $51.50 | $44.50 |
| Unlimited, 30 days | $73.90 | $76.50 | $64.50 |
Prices checked Nov 9, 2026, in US dollars. Prices go down per day the longer the plan. The price on Holafly's site when you buy is the one that counts.
A 10-day trip to Japan works out to about $3.65 a day, against the $12 a day of a US carrier's day pass.

Is Holafly really unlimited?
On your phone, almost. Holafly doesn't publish a daily amount after which it slows you down, which Airalo and Saily both do on their unlimited plans.
| Provider | 10 days | Full speed each day |
|---|---|---|
| Holafly | $36.50 | No cap stated |
| Airalo | $34.50 | 3 GB, then 1 Mbps |
| Saily | $34.99 | 5 GB, then slower |
Airalo is a little cheaper, but 1 Mbps after 3 GB is too slow for video. Holafly's plan pages do mention one limit: under a fair usage policy, a busy network can slow you for up to a day, and full speed returns the next day. The other limit is sharing, covered just below.
Is Holafly worth it, or is 10 GB enough?
Most trips don't need unlimited. Ten days of maps, messages and a few photos fit in 10 GB, which costs a third to half as much.
| Country | Holafly, 10 days | 10 GB plan I pick |
|---|---|---|
| Japan | $36.50 | $16.50 (Ubigi) |
| Thailand | $36.50 | $10.00 (Nomad) |
| Spain | $33.50 | $12.00 (Ubigi) |
| Greece | $37.50 | $12.00 (Ubigi) |
The gap pays for not thinking about data. If you'll watch shows on the train, back up every photo to the cloud or spend an hour a day on FaceTime, Holafly is the easy choice. If not, the data calculator tells you in a minute whether 10 GB covers you.
Heavy user, 10 days in Japan: Unlimited, 10 days costs $36.50.
Get Holafly unlimitedHolafly hotspot: the 1 GB a day limit
Unlimited applies to your phone. Share its connection with a laptop or a partner's phone and Holafly stops you at 1 GB a day.
The 10-day plan comes with 10 GB of sharing in all. That's enough for a tablet or a few hours of email, but a single video call on a laptop can use about 1 GB an hour. If you'll work remotely, a big fixed plan that allows hotspot does better: in Japan, Nomad's 50 GB, 30 days costs $35.00. For a family sharing one connection, the pocket Wi-Fi or eSIM guide for Japan weighs the router option.
Holafly eSIM in Japan and Italy
The two countries where Holafly is most often weighed against a 10 GB plan, on different networks each time.
Japan: KDDI and SoftBank, with 5G
Holafly runs on KDDI (au) and SoftBank in Japan, with 5G, and 10 days cost $36.50. It doesn't say which country your connection comes out in. For maps, trains and LINE, Ubigi's 10 GB, 30 days costs $16.50 on Docomo and KDDI, and users report a Japanese address. All five Japan plans are side by side on the best eSIM for Japan page.
Italy: Vodafone and WindTre
In Italy, Holafly uses Vodafone and WindTre, and 10 days cost $32.90. It doesn't say whether you get 5G there. For most trips the pick is Ubigi, 10 GB, 30 days for $12.00. Holafly earns its place if you'll film and post from Positano or Venice every day. The five Italy plans and their networks are compared on the best eSIM for Italy page.
Holafly for Europe and China
Two trips where Holafly gets compared a lot, with a different answer each time.
Europe: 33 countries
Holafly's Europe plan covers the UK, Switzerland, Iceland and Norway, and costs $37.50 for 10 days. It leaves out Turkey, Ukraine and the Balkans outside the EU. For a route that reaches Istanbul or Belgrade, Airalo Eurolink covers 41 countries; the best eSIM for Europe page compares the three Europe plans.
China: no VPN needed, says Holafly
Holafly writes on its China page that WhatsApp, Google and Instagram work without installing a VPN. Its 10 days cost $37.50. Airalo says the same and sells 10 GB, 15 days for $25.50, so Holafly only makes sense in China if you need unlimited data. Hotel Wi-Fi stays filtered with either.
What are the disadvantages of Holafly?
Four, and the first one is the price.
Expensive for light users
You pay for unlimited whether you use 3 GB or 30. For maps and messages, a 10 GB plan costs a third to half as much.
Hotspot capped at 1 GB a day
Fine for a tablet, too little for a laptop workday.
No phone number
The plans are data only. Calls go through WhatsApp or FaceTime, and your US line keeps your number.
Slowdowns are possible
There's no published daily cap, but Holafly says a network may slow you for up to a day under fair usage.

Holafly review questions
Is Holafly safe to use?
Yes. Holafly sells data-only travel eSIMs that install like any other eSIM from a QR code. It adds a second data line to your phone and leaves your US line alone, so your number keeps working for calls, texts and bank codes.
Does Holafly's unlimited data plan have a daily limit?
Holafly publishes no daily full-speed amount. Its plan pages say a network may slow your speed for up to one day under a fair usage policy, then it resets. Sharing data as a hotspot is limited to 1 GB a day.
How much does Holafly eSIM cost?
In Japan, $11.90 for 3 days, $36.50 for 10 days and $73.90 for 30 days, all unlimited (Nov 9, 2026). Europe costs a little more: $37.50 for 10 days.
Can I use Holafly as a hotspot?
Yes, up to 1 GB a day. That covers a tablet or a few hours of email on a laptop, not a workday of video calls. For laptop work, take a large fixed plan that allows hotspot, such as Nomad's in Japan.
Do you keep your number with Holafly?
Yes. Holafly is data only and doesn't touch your US line, which stays on for calls, texts and bank codes. Turn off Data Roaming on your US line so it can't charge you a day pass.
