Skip home-carrier data roaming, physical SIM collection or swaps, contracts, airport kiosk queues and ID checks. You only need an eSIM-capable, carrier-unlocked phone to use your travel data.
Keep your existing number while the eSIM handles data only. Your own SIM stays in your phone for calls, SMS, WhatsApp and bank codes on that number.
Match your plan to your route: short plans suit Tokyo city breaks, while longer options suit travellers combining Kyoto temples, Osaka food stops and time in Hokkaido.
Arrive with your eSIM already installed before departure, ready to connect in Japan. Aim to get online before passport control instead of hunting for airport Wi-Fi after landing.
What it is not: a phone number. For a local number to receive sign-up codes or bookings, add a virtual number next to the data plan.
How it works
Land in Japan already online
Set it up on Wi-Fi the night before. The eSIM waits quietly until you arrive.
2
Pay and scan the QR code
Pay from your balance and get the QR code at once.
3
Turn it on when you land
Turn on data roaming and it finds a network itself.

What customers say
Best virtual number website
Using this site from more than 1 month and everything works perfect till now.. no problem faced.. UI is simple and easy to understand, buying number is fast.. numbers are always fresh and otp comes instantly no waiting time.. I really suggest them best site in 2026
Worked as intended
Well, it worked as intended. It was very easy to use the service, so I can only recommend it. Wish there were help desk to check some questions but regardless it was a satisfactory purchase.
Excellent service. So happy I found it
Excellent service. Works when it works and replaced when it doesnt. Fair pricing and good perks as well.
It definitely works
It definitely works, but it can be confusing if you are not aware of what some of the services do to prevent having multiple numbers. WhatsApp will try to prevent you from making a new number on the same phone. Just have to use another phone to create the account and then you can sign in properly. I was confused why I kept going through so many numbers not working, but it was because I was using the same device that I recently had an account on. I deleted my previous account, but WhatsApp saves your device info for 30 days.
Much more reliable
SMS a little more expensive than other pages, but they are much more reliable, and work.
My experience has been great
My experience has been great because 1001sms has made my job so effortless and a 10 man task feel like a job for just 1.
Great service
Great service, absolute amazin for 3rd Countries who cant use amaing services without phone numbers
I have used number from this site and it's good
I have used number from this site and it worked perfectly. 1001sms is a good choice when it comes to getting number from any country and any service

FAQ
Using an eSIM in Japan: your questions
You need an eSIM-capable, carrier-unlocked phone to use these Japan plans. Dial *#06# to look for an EID, which identifies your phone’s eSIM.
Yes, your own SIM stays in your phone while the eSIM supplies data. Keep your existing number for calls, SMS and WhatsApp during your Japan trip.
Use your own SIM for bank codes sent by SMS in Japan. The travel eSIM provides data only and cannot receive those text messages itself.
Hotspot support is not confirmed for these Japan plans. Your phone having a hotspot setting alone does not establish whether a plan allows sharing.
You can buy another Japan plan using your prepaid account balance. Your new purchase comes with its own QR code and manual activation code.
You can buy another plan for the rest of your Japan stay. Its validity starts on its first connection, not when you pay for it.
Select your eSIM for mobile data in your phone settings in Japan. Turn on data roaming for that eSIM, then try restarting your phone.
