eSIM Signal for Japan FAQ

Does eSIM Signal offer unlimited data eSIM for Japan?

eSIM Signal does not provide a truly unlimited data eSIM for Japan. The plans that carry the “Unlimited” name give 5GB/day at full speed and then throttle to 1 Mbps, so the data allowance is capped.

Travelers who need a larger data allowance can choose fixed data plans such as Japan 1000GB – 3 days or Japan 1001GB – 4 days, which offer up to 1 001 GB of high‑speed data for a set validity period. These fixed plans can be more cost‑effective unless the user is an extremely heavy data consumer.

Does eSIM Signal offer Japan eSIM with phone number and SMS?

eSIM Signal does not provide an eSIM for Japan that includes a phone number or SMS capability. The available plans for Japan are data‑only. Travelers can still communicate over the internet by using VoIP applications such as WhatsApp, Telegram, or iMessage between the data connection. However, some destinations may restrict or block certain VoIP services, so it is advisable to check whether the apps you need are accessible in Japan before making a purchase.

How many data plans does eSIM Signal offer for Japan?

The available dataset lists overall totals for all eSIM providers but does not break them down by individual operator or country. As a result, the exact number of single‑country and multi‑country plans that eSIM Signal offers for Japan cannot be determined from the data presented.
