Yatelo eSIM Data Plans for Japan

Yatelo does not provide a true unlimited data eSIM for Japan; all of its Japan‑specific plans have a fixed data allowance. The plans titled “ASI Unlimited 3GB” offer 3 GB of high‑speed data, after which the speed is throttled to 1000 kbps, so they are not unlimited. Travelers looking for larger data packages can choose from Yatelo’s fixed‑data plans such as the JPN 50GB 30‑day plan (50 GB), the JPN 20GB 30‑day plan (20 GB), or the JPN 10GB 30‑day plan (10 GB), each allowing tethering and high‑speed data on 5G networks in Japan.

Yatelo does not offer any eSIM plan for Japan that includes a phone number or SMS capability. Only data‑only eSIMs are available from Yatelo in Japan, and travelers can use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection. Since some destinations may block or restrict certain apps or VoIP services, travelers should verify that the apps they need are accessible in Japan before purchasing a plan.

Yatelo provides a range of data options that include both single‑country and multi‑country plans for Japan. Specifically, there are seven single‑country plans that cover Japan alone and seventeen multi‑country plans that include Japan among other destinations. The plans vary from inexpensive plans that start around $1.54 with a 1 GB data cap to premium choices that cost up to $54.02 and offer up to 50 GB of data, with validity periods ranging from 3 to 30 days. Many of these plans feature fixed data amounts, and some also allow tethering while maintaining a reduced speed of 1000 kbps.
