eSIM Prices for Japan and Europe: Every LeafySIM Plan and What It Costs
Japan runs from $3.49 for 1GB over 7 days up to $79.99 for 50GB over 180 days. Europe runs from $4.49 to $103.49 across 34 areas on one eSIM. Both are data only and both arrive by email as a QR code. A seven day plan for either destination costs under $5, against $50 for the cheapest carrier pass covering the same week, though the carrier pass carries more data and includes calls. The full tables are below.
Japan eSIM prices
One country, and you are on a real local network. The host networks are NTT docomo, KDDI/au, SoftBank and Rakuten Mobile, so coverage matches what people living there get.
| Plan | Valid for | Price |
|---|---|---|
| 1GB | 7 days | $3.49 |
| 3GB | 30 days | $6.49 |
| 5GB | 30 days | $8.99 |
| 10GB | 30 days | $14.49 |
| 20GB | 30 days | $24.49 |
| 50GB | 30 days | $48.99 |
| 50GB | 180 days | $79.99 |
Europe eSIM prices
One eSIM covers 34 areas, so a trip through several borders runs on a single install with nothing to swap. The list includes the United Kingdom, which surprises people who expect a separate plan after Brexit.
| Plan | Valid for | Price |
|---|---|---|
| 1GB | 7 days | $4.49 |
| 3GB | 30 days | $11.99 |
| 5GB | 30 days | $17.49 |
| 10GB | 30 days | $28.99 |
| 20GB | 30 days | $48.49 |
| 50GB | 180 days | $103.49 |
If your whole trip is Britain, buy the United Kingdom eSIM instead. It enters lower than the Europe plan, and you are not paying for 33 countries you will not visit.
One regional plan, or several country plans?
This is the question that decides what you spend, and most comparisons answer it badly. Here is the arithmetic run against our own live prices.
| Your trip | Cheaper buy |
|---|---|
| One country | The country plan, every time |
| Two countries | Usually two country plans, but it is close |
| Three countries | The regional plan, in almost every combination |
| Four or more | The regional plan, and it is not close |
Europe is the clearest case. Three European country plans at the 5GB tier come to about $26, against $17.49 for the Europe plan that covers all 34 areas. Four countries widens it further, and you are still installing one eSIM instead of four.
The exception worth knowing: if the countries you are visiting happen to be the cheapest ones in the region, buying separately can still edge it at three. Run your own itinerary against the tables above rather than trusting a rule of thumb, including ours.
And the reason this matters beyond the money. Every extra plan is another purchase, another install, and another trip to your settings menu at a border. On a two-country trip that is a minor irritation. On a five-country trip it is the thing you forget at the worst moment.
What the same week costs on your own carrier
These are read from the carriers' own rate cards, not from a comparison site.
| Option | Cost | Data |
|---|---|---|
| Verizon TravelPass, 7 days | $84.00 | Unlimited, throttled |
| AT&T International Day Pass, 7 days | $84.00 | Unlimited, throttled |
| T-Mobile International Pass, 10 days | $50.00 | 15GB |
Fifty dollars is the cheapest route a US carrier customer actually has for a week abroad, so that is the honest number to compare against. Roam with no package at all and AT&T bills $2.05 a megabyte.
One thing worth saying plainly, because most comparisons skip it. A carrier day pass also covers calls and texts on your own number. Ours is data only. If you need your own number to ring, buy the carrier pass. If you live on WhatsApp, maps and rideshare, that difference costs you nothing.
Which plan should you pick?
We do not publish a recommendation like "3GB is enough for two weeks", and that is deliberate. We have not measured how much data real travellers use on these plans, and every guide that gives you a confident number is guessing at your habits. What we can tell you is what each plan costs and how long it lasts, which is the table above.
Two things that are true regardless. Every plan tops up, so running short is a purchase rather than a problem. And every plan is refundable in full until you install it, so buying the smaller tier first costs you nothing but a minute.
Common questions
Why do you only show a "from" price everywhere else?
Because prices are set per destination and the cheapest one is wrong for most places. A single figure next to a claim about 200 destinations would be misleading. This page exists so the real numbers are somewhere you can read them.
Do these prices change?
They do. This page was written on 20 August 2026 and the plan pages are always current. If the two ever disagree, the plan page is right.
Will a travel eSIM work on my phone?
Your phone needs to be eSIM capable and carrier unlocked. That covers iPhone XS and later, Google Pixel 3 and later, and recent Samsung Galaxy S and Note models. Open Settings and look for an eSIM or Digital SIM option. If your phone cannot use one, you have not installed anything yet, so we refund you.
Will I lose WhatsApp and my own phone number?
No. Your normal SIM stays in the phone and keeps your number. The travel eSIM sits alongside it and carries data only, so WhatsApp, iMessage and your usual apps keep working on the number your contacts already have.
Can I buy after I have already landed?
Yes, if you can get online for a minute. Airport or hotel Wi-Fi is enough to install it. Buying before you fly is easier, because the QR code is waiting in your inbox and the plan starts when you arrive.
