The Airalo Japan eSIM is data only, and its unlimited packages slow to 1 Mbps once you use more than 3GB in a day. Our Global eSIM is unlimited across 165+ countries, with one flat price for the trip length you pick.
Nobody wants to find a daily limit halfway through a day in Shibuya.
The Airalo Japan eSIM includes data only, with no number or calls
The Airalo Japan eSIM includes data only, with no number or calls.
Airalo says some of its packages come with calls and texts. The Japan eSIM isn’t one of them. Airalo also says every package includes an amount of data valid for a period of time, and that some packages have unlimited data.
To complete an order, Airalo asks you to confirm your device is eSIM-compatible and network-unlocked. Airalo sells per country, per region, or as one global plan, priced in USD.
How much is an Airalo unlimited eSIM for Japan by trip length?
Airalo’s unlimited Japan packages run from $17.00 for 5 days to $69.00 for 30 days, priced in USD (Airalo, 2026). The 7-day package costs $26.50 and the 10-day package costs $34.50.
The 15-day package costs $48.00. Every one of these is a separate package on Airalo’s Japan page, so the price climbs with the days you pick.
What do fixed-data Airalo Japan eSIM packages cost?
Airalo’s fixed-data Japan packages start at $4.00 for 1GB over 3 days (Airalo, 2026). The range runs from $4.50 for 1GB over 7 days up to $26.00 for 20GB over 30 days.
Fixed data is a set amount of gigabytes, and when it’s gone, it’s gone. That’s the opposite of the unlimited packages above, which have no fixed total.
Will an Airalo unlimited package run out of data in Japan?
No. Airalo says its unlimited packages have no fixed total data cap, so you do not run out of data during the validity period. On any day you use more than 3GB, Airalo slows your connection to 1 Mbps for the rest of that day.
At 1 Mbps, Airalo says you can still send and receive messages, browse simple web pages, use maps for navigation and make lower-quality video calls. Video streaming, gaming and large file downloads will be slower until your speed resets.
Airalo adds a second rule. The networks behind its packages may apply traffic management during busy periods, which can cut speeds separately from the 3GB threshold. Airalo makes no warranty as to connection speed, quality or availability at any given time.
When does the Airalo daily data allowance reset?
Airalo counts a day as each 24-hour period that begins when you activate your eSIM, and the allowance resets every 24 hours from that moment. Full speed returns automatically at the reset.
The 3GB threshold is Airalo’s default. Where a package uses a different threshold, Airalo says it’s set out in the package details before you buy.
That makes your activation time the clock. A reset lands at the same time each day, wherever you are standing.
What should you check in an unlimited eSIM before a Japan trip?
Check three numbers before you pay: the daily high-speed threshold, the speed you drop to after it, and how the provider counts a day. Airalo’s unlimited packages set 3GB a day, 1 Mbps after it and a 24-hour day counted from activation, and each other provider sets its own.
Look for the threshold in the package details before you buy. Then find the speed after it, and the point where the day starts counting. Three lines of fine print, two minutes, and your Japan data plan holds no surprises.
Which travel eSIM should you buy when unlimited data has a daily limit?
The table sets each provider’s published unlimited terms, daily allowance and plan structure side by side, copied from each company’s own words. Our Global eSIM sits in the same table.
Airalo’s cell also says its unlimited packages are designed for personal, non-commercial use. Saily, Nomad and GigSky each publish a daily allowance of their own.
| Travel eSIM | How plans are sold | Unlimited plan allowance, as published | Hotspot, as published |
|---|---|---|---|

| Airalo | Per country, per region, or one global plan; priced in USD | Our unlimited data packages don’t have a fixed total data cap. However, to keep the network running fairly for everyone, when you use more than 3GB in a day, we’ll slow down (or “throttle”) your internet speed to 1 Mbps for the rest of that day. Your full high-speed connection will automatically be restored when your daily allowance next resets. Your daily allowance resets every 24 hours, counted from the time you activated your eSIM. | Our unlimited data packages are designed for personal, non-commercial use. You are welcome to use your package for everyday activities like browsing, streaming, messaging, video calling and social media. |
| Saily | Per country and per region, plus one global plan; by the gigabyte, unlimited, or both | The Unlimited plan gives you 5 GB per day at full 4G/5G speed, then keeps you online at 1 Mbps for the rest of the day — fast enough for navigation, messaging, and standard browsing. | Hotspot sharing: Unlimited! Share as much of your mobile hotspot with friends and family as you want. |
| Nomad | Per country, per region and global plans; by the gigabyte and unlimited | Once the daily allowance of 2 GB is used, data speeds are reduced (throttled) for the rest of the day. Depending on the specific plan, this reduced speed is approximately 1 Mbps or 2 Mbps. | Yes, Nomad’s eSIMs support tethering / hotspot. |
| GigSky | Per country, per region, and cruise plans; by day, unlimited data with 3.5GB daily high-speed allowance | Get up to 3.5GB/day at our fastest speeds: Video calls, uploads, streaming and more. | Turn your phone into a hotspot and share your connection with your laptop, tablet, or travel companions. There’s no extra charge for hotspot use, giving you more flexibility while you’re onboard. |

FAQ
How do I check that my phone supports an eSIM before I fly to Japan?
Check your model against our compatible-phones list. Supported iPhones include the iPhone 11, 12, 13, 14, 15 and 16 series, iPhone XS, XS Max, XR, and the SE 2nd Gen. (2020) and 3rd Gen. (2022). On the Samsung side, the Galaxy S20 through S25 series, Z Flip and Z Fold models, A34, A54, A55 and A56 5G, Fold and Note20 models are supported. Oppo, Motorola and Huawei phones are on the list too.
Should I install my eSIM before I leave for Japan?
Yes. Installing needs an internet connection, so start on Wi-Fi; Maya takes 3 minutes to install and stays on the phone permanently. The days of your plan begin counting once you enable the Maya eSIM in phone settings. When you land, switch it on and select it for Cellular Data.
Does the Maya Global eSIM work in Japan?
Yes. Maya eSIMs work in Japan and 165+ additional destinations worldwide. One eSIM, installed once, covers them all.
What does unlimited mean on the Maya Global eSIM?
Each plan comes with a daily high-speed data allowance called the Daily Quota, running at up to 4G LTE or 5G where local networks offer it. It refreshes automatically every 24 hours. Once it’s used, data continues at standard speed. No speed is guaranteed, and coverage depends on the local network.
How many days should my eSIM plan cover for a Japan trip?
Match the plan to your days on the ground. A 3-day plan costs $9.99, 7 days costs $19.99, 14 days costs $27.99 and 30 days costs $49.99. The 14-day plan works out to $2.00 a day.
What happens when my eSIM plan’s days run out?
The plan ends. Each plan is a one-time purchase, and there’s no automatic recurring charge unless you turn on Auto Top-Up. Auto Top-Up is opt-in and off by default, and you can turn it off any time from My eSIM. When you turn it on, it buys your next plan.
Can I get a refund on an eSIM plan I have not used?
Often, yes. Under the Money Back Guarantee, you can be covered if a trip is cancelled, your phone is not compatible with eSIMs, you bought an extra or unneeded data plan, or the eSIM is unused or consumed no data. If the eSIM can’t be installed because the device is incompatible or carrier-locked, a full refund less payment processing fees is available when no data was consumed and the request comes within 30 days of purchase. An Unlimited plan that has consumed more than 1 GB generally can’t be returned, and the Terms hold the remaining cases.
What do I do if my eSIM will not connect after I land in Japan?
In your phone settings, confirm the Maya eSIM is switched on and chosen for Cellular Data. Slow speeds, only an “E” in the status bar with no 4G/LTE, or no internet despite a connection are all symptoms of an eSIM not connected to a data network. If an iPhone shows “Unable to Activate eSIM,” the eSIM may already be installed on the phone, and the eSIM Connection Troubleshooting Guide walks you through the settings.
Maya gives you one Global eSIM with unlimited data across 165+ countries, at a flat price by trip length.
