eSIMzio for Japan FAQ

Does eSIMzio offer unlimited data eSIM for Japan?

eSIMzio does not provide a truly unlimited data eSIM for Japan. All of its Japan‑only plans listed as “Unlimited” actually give 3GB of high‑speed data per day; after that amount the speed drops to 1Mbps. Travelers who want higher capacity can choose from the fixed data plans offered by eSIMzio, such as the 100GB plan valid for 180 days or the 50GB plan for 90 days, which provide larger data allowances and can be more cost‑effective for heavier usage.

Does eSIMzio offer Japan eSIM with phone number and SMS?

eSIMzio does not offer any Japan eSIM plans that include a phone number or SMS capability. The provider’s offerings for Japan are strictly data‑only, with no inbound or outbound voice or text services attached.

Travelers who need to stay connected can use popular VoIP applications such as WhatsApp, Telegram, iMessage and others over the data connection. However, some destinations may restrict access to specific VoIP services, so it is advisable to confirm that the apps you rely on work in Japan before purchasing an eSIM from eSIMzio.

How many data plans does eSIMzio offer for Japan?

eSIMzio lists 13 single‑country data plans that cover Japan only and 42 multi‑country plans that include Japan among other destinations. The single‑country offerings are daily‑cap plans, where a fixed amount of data is available each day for a short validity period, while the multi‑country plans provide a fixed data allowance that can be used across several countries during the plan’s validity. Prices for these Japan‑targeted plans span from roughly $2.03 to $227.72, and the data caps range from 200 MB up to 100 GB, with validity durations between three and 365 days.
