ESIM.DOG 🐶 eSIM Data Plans for Japan

ESIM.DOG 🐶 does not offer a truly unlimited data eSIM for Japan. The plan titled “⚡️ [5G] SoftBank/KDDI/au Japan - Best Unlimited 5G Coverage” actually provides only 1GB of high‑speed data; after the 1GB limit is reached the speed drops to 1000kbps, so it is not an unlimited plan.

Instead, ESIM.DOG 🐶 sells fixed data plans. For example, a 50GB plan that lasts 30 days costs $21.24 USD, and a 30GB plan that lasts 30 days costs $49.99 USD. These plans give users a set amount of high‑speed 5G or 4G data each month. Choosing a fixed data plan can be more cost‑effective for travelers who need a substantial amount of data but are not extreme data users.

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.

ESIM.DOG offers 26 single‑country data plans for Japan and does not provide any multi‑country plans. The plans range in price from about $0.50 to $49.99 and cover data from 100 MB up to 50 GB, with validity periods that span 1 to 180 days. Some of the single‑country options allow tethering and have a reduced speed threshold of 1000 kbps.
