Roambit for Japan FAQ

Does Roambit offer unlimited data eSIM for Japan?

Roambit sells a range of unlimited‑data eSIM plans for Japan that vary in validity from 1 day up to 80 days, with prices from about $3.20 to $93.60 USD. The unlimited data is delivered over 5G, but users should be aware that speeds may be throttled after heavy usage because a Fair Usage Policy applies. For details on the typical amount of data available at normal speed or to confirm whether FUP applies to a specific plan, travelers should contact Roambit directly.

Does Roambit offer Japan eSIM with phone number and SMS?

Roambit does not offer a Japan eSIM plan that includes a local phone number or telephone/SMS capability. All of Roambit’s Japan offerings are strictly data‑only, so travelers will not receive an inbound or outbound voice or SMS service.

If a phone number is needed, users may rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the Roambit data connection. However, some destinations may restrict or block specific apps, so users should verify that the apps they depend on are accessible in Japan before purchasing a plan.

How many data plans does Roambit offer for Japan?

Roambit offers 20 single‑country data plans that cover Japan and a further 10 multi‑country plans that include Japan. The available price range is $3.20 to $99.99, while the data caps span from 3 GB up to unlimited, giving travelers a broad selection to match their travel duration and data needs.
