14-day eSIM for Japan
For fourteen days in Japan, 3 GB for 4,90 € covers the classic route: Maps daily, translator, messaging, and photos at night on the hotel Wi-Fi. If two of you are sharing, or you lean hard on video, the 1 GB-a-day pass at 20,90 € takes the arithmetic off your plate.

Fourteen days is the trip almost everyone does: Tokyo, Hakone or Nikko, Kyoto, Nara, Osaka and back. And it's exactly the length people get wrong when buying, because they work out what they use in a weekend and multiply it by seven.
How much you use in two weeks
In Japan you look at your phone a lot but use little data. You find your way round the Tokyo metro with Maps, and that's some 100 MB a day at the generous end. The camera translator uses less than it seems. Looking up trains, next to nothing.
What eats the gigabytes is uploading content and watching video. And on a trip to Japan you tend to do that at night, sprawled on the hotel bed, on its Wi-Fi.
| How you travel | Estimated usage over 14 days | Plan |
|---|---|---|
| Maps, translator and WhatsApp | 1,5 – 2,5 GB | 15 days · 3 GB — 4,90 € |
| Plus social media daily | 3 – 5 GB | 30 days · 5 GB — 5,90 € |
| Two people on a single plan | 5 – 8 GB | 30 days · 10 GB — 9,90 € |
| Video daily, or remote work | more than 8 GB | 1 GB-a-day pass — 20,90 € |
Look at the second row: 30 days with 5 GB costs 5,90 € and the 15-day one with 3 GB costs 4,90 €. One euro's difference for two more gigabytes and twice the margin in days. For fourteen days, the 30-day plan is usually the sensible buy.
How to split it if there are two of you
Two options, and neither is obviously better. An eSIM each lets you go your separate ways the day one of you wants Nara and the other Osaka, and it comes to 4,90 € each. A single bigger plan with hotspot sharing works out somewhat cheaper, but it ties both phones to staying close and drains a fair bit of battery on whichever one plays router.
Can I use a 30-day plan for a 14-day trip?
Yes. The days are the maximum validity, not an obligation to use them up. You buy the 30-day one, use it for fourteen and it expires on its own.
What if I run out of data mid-trip?
You can buy another plan and activate it, or switch to the day pass. To avoid it, check your usage in the phone's settings around day seven: if you're at about half, you'll make it.
Do I count the flight days?
Count from the moment the eSIM connects in Japan. If you land on the morning of day 1 and fly home on the night of day 14, fourteen days of validity is cutting it fine but you make it; with the 30-day plan you don't even think about it.
