Frequently Asked Questions

Does ESIM.DOG 🐶 offer unlimited data eSIM for Japan?

ESIM.DOG does not offer a truly unlimited data eSIM for Japan. The only plan that carries the word “Unlimited” in its name provides 1 GB of high‑speed data; once that limit is reached the speed is reduced to 1000 kbps.

Instead, ESIM.DOG offers fixed‑data plans that give larger amounts of high‑speed data before throttling. Examples include the 50 GB plan valid for 30 days at $21.24 USD, the 30 GB plan valid for 30 days at $49.99 USD, and the 20 GB plan valid for 30 days at $10.23 USD or $34.49 USD. These options may be more cost‑effective unless a traveler is an extremely heavy data consumer.

Does ESIM.DOG 🐶 offer Japan eSIM with phone number and SMS?

ESIM.DOG 🐶 does not provide a Japan eSIM plan that includes a phone number or SMS functionality. The provider offers only data‑only eSIMs for travelers visiting Japan.

Travelers who need to make voice calls or send text messages can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection that ESIM.DOG supplies. These apps allow voice and messaging without requiring a local phone number or SMS support.

How many data plans does ESIM.DOG 🐶 offer for Japan?

The provider lists 19 single‑country data plans for Japan, with prices ranging from $0.50 to $49.99 and data caps from 100 MB up to 50 GB for plans valid between 1 and 180 days. No multi‑country options are available.
