ESIM.DOG 🐶 eSIM Data Plans for Japan

ESIM.DOG 🐶 does not provide a truly unlimited high‑speed data eSIM for Japan. The plan titled “Best Unlimited 5G Coverage” is actually limited to 500MB of 5G data, after which the speed is throttled to 384 kbps, so it does not offer data without limits.

If you need more data, ESIM.DOG 🐶 offers fixed‑data plans that may suit most travelers. A 100 GB plan is available for 180 days at $159.99 USD, an 80 GB plan for 365 days at $149.99 USD, and several 50 GB options ranging from 5 days to 30 days with prices between $19.88 and $21.24 USD. These fixed plans may be more cost‑effective unless you are an extremely heavy data user.

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.

In Japan, ESIM.DOG offers 212 single‑country data plans and 269 multi‑country plans. Prices span from around $0.50 to $221.48, while data caps range from 100 MB to 100 GB, with validity periods between one day and one year. Some plans include tethering, and a limited‑speed option is available at 384 kbit/s.
