3 out of 5 stars
Japan

“Not that fast but okay-ish speeds in Japan on the KDDI (au) network. However, the biggest drawback is that this eSIM routes through Hong Kong (HK IP address), so ChatGPT doesn’t work which is a real shame.”

Saily for Japan FAQ

Does Saily offer unlimited data eSIM for Japan?

Saily does not provide a true unlimited data eSIM for Japan. All plans titled “UNLIMITED” actually supply 5GB of high‑speed data per day; once the daily allowance is reached the speed is throttled (to 1kbps or 1000kbps depending on the specific plan). If a traveler needs a large amount of data without bandwidth reductions, fixed data plans are an alternative. For example, Saily offers a Japan 20GB 30 days plan, which gives 20GB of data over a month, and a Japan UNLIMITED 15 days plan, which gives 5GB of high‑speed data per day for 15 days before throttling occurs. Choosing a fixed data plan can often be more cost‑effective than selecting a plan that limits speed after a certain threshold.

Does Saily offer Japan eSIM with phone number and SMS?

Saily does not provide a Japan eSIM that includes a phone number or SMS capability. The provider offers only data‑only plans, so travelers who need voice or text services will need to rely on VoIP applications such as WhatsApp, Telegram, or iMessage. These apps generally function over the data connection, but some destinations may restrict or block them, so users should check whether the services they rely on are accessible in Japan before purchasing a Saily eSIM.

How many data plans does Saily offer for Japan?

Saily provides 12 single‑country plans that cover Japan and 22 multi‑country plans that include Japan in their coverage. The single‑country plans are a mix of daily data‑cap options and fixed‑data‑cap offerings. Across these plans, prices range from $3.99 to $159.99 and data caps vary between 1 GB and 30 GB.
