BetterRoaming eSIM Data Plans for Japan

BetterRoaming does not provide an unlimited data eSIM for Japan. The available plans give fixed data allowances of 20 GB, 10 GB, or 5 GB for 30 days in Japan. The largest option is the Local Japan – 30 Days – 20 GB plan, priced at $45.99 USD, while a 10 GB plan is available for $26.99 USD. Choosing a fixed‑data plan can be more cost‑effective than seeking unlimited service, especially for travelers who do not require extreme data usage.

BetterRoaming does not provide a Japan eSIM that includes a phone number or SMS capability. The provider offers only data‑only plans for travel in Japan, and those plans do not support inbound or outbound voice or text messaging. Travelers seeking to make calls or send texts can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, which allow communication without a local phone number or SMS service.

BetterRoaming currently offers 5 single-coverage data plans specifically for Japan, alongside 8 plans that include Japan as part of a broader multi-country coverage area. These plans range in price from $4.49 to $59.99 and provide data allowances between 1GB and 20GB. Some plans offer a fixed data amount for the duration of the plan’s validity, while others provide data for a set number of days. Plan validity ranges from 7 to 30 days.
