Description
Japan's prepaid SIM market is tourist-unfriendly — most contracts require a Japanese address and a hanko seal. A roamgo eSIM works around all of it: install at home, activate at Narita or Kansai, and you're navigating the Tokyo subway map within minutes of landing.
After purchase, your Globalia eSIM details are delivered digitally. Install before you travel, then connect to a fast and stable internet connection in Japan.
It's connectivity that fits your needs
First-time Tokyo visitors needing Google Translate and Tabelog; bullet-train travellers between Tokyo, Kyoto, and Osaka; ski-season trips to Niseko or Hakuba.
Stay connected everywhere
Data, phone numbers, international calls and SMS. All in one app.
One balance for everything
Top up once and use your credits for data, calls, and SMS.
Single Global eSIM
Roams onto NTT Docomo, SoftBank, and au by KDDI. Docomo has the strongest coverage in mountainous areas (Mt Fuji climbers, ski resorts); SoftBank tends to be fastest in central Tokyo.
Local tip
5G is rolling out fast in the Greater Tokyo and Osaka areas but rural prefectures stay 4G LTE — both are fast enough for video calls and offline-map downloads.
Connection information
How does Globalia eSIM work?
Data plans and pay as you go use a single global eSIM, so you do not need to install a new eSIM for every country.
How does my data plan activate?
Activation timing depends on the selected Japan plan. Check its Starts field before checkout: validity may begin at purchase, installation, or first supported-network connection.
What happens when my data plan expires?
You can add another plan or switch to your available Globalia balance when pay as you go is enabled.
Can I make calls with Globalia?
Yes. Calls are handled through Globalia Credits and work alongside your data plan.
Can I use data plans for calls?
Data plans are for mobile data. Calls and SMS use Globalia Credits or Globalia Numbers.
