Roamic for Japan FAQ

Does Roamic offer unlimited data eSIM for Japan?

Roamic’s plans that carry the label “Unlimited” are not truly unlimited. Each of these plans provides 3GB/day of high‑speed data for the stated validity period, and after that amount the speed is reduced to 1000kbps. Consequently, travelers who need unrestricted data will not get that service from Roamic in Japan.

If unlimited high‑speed data isn’t required, Roamic offers sizeable fixed data options that may be more cost‑effective. For example, the Japan eSIM 50GB / 30 days plan gives 50GB of data for 30 days at $39.14 USD, and the Japan eSIM 20GB / 30 days plan provides 20GB for $16.77 USD. These fixed data plans keep the original speed for the entire validity period and can be a better choice for heavy users.

Does Roamic offer Japan eSIM with phone number and SMS?

Roamic does not provide eSIM plans for Japan that include a mobile phone number or native SMS capability. The provider only offers data‑only eSIMs that allow internet access. Travelers who need to make voice or text communications can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, availability of these apps can be affected by restrictions in certain destinations, so users should confirm that the services they rely on are accessible in Japan before purchasing an eSIM from Roamic.

How many data plans does Roamic offer for Japan?

Roamic offers 14 single‑country data plans that cover Japan, and 5 multi‑country plans that include Japan as part of a broader regional package. The available plans span a price range from $1.99 to $64.99 and provide data caps between 1 GB and 50 GB. Within these options, 12 plans provide a fixed data amount for the entire validity period, while 7 plans feature a daily data cap that resets each day.
