Halo eSIM eSIM Data Plans for Japan

Halo eSIM does not provide a truly unlimited data eSIM for Japan. The plans marketed as “Japan Unlimited” actually allow 3 GB of high‑speed data each day; once that amount is reached the speed is lowered to 1 Mbps for the remainder of the day. These plans come in validity periods ranging from 3 days to 30 days. For travelers who need a larger, more predictable data supply, Halo eSIM offers fixed data plans such as the 10 GB/30 days or 20 GB/30 days options, which provide the full data allowance at full speed until the 30‑day period expires. Choosing a fixed data plan can be more cost‑effective unless a user expects extremely heavy daily data usage.

Halo eSIM does not offer a Japan eSIM that includes a phone number or SMS capability. The only plans available for Japan are data‑only plans. Travelers who need to communicate over a data connection can use VoIP applications such as WhatsApp, Telegram, or iMessage, but they should verify that any particular app or service they rely on is accessible in Japan before purchasing.

Halo eSIM provides 12 single‑country data plans and 15 multi‑country plans that cover Japan. The catalog includes both fixed data amount plans, which grant a set amount of data for the entire validity period, and daily data cap plans, which limit the amount that can be used each day. Across the available plans, prices range from about $2.63 to $72.46 and data caps vary from 1 GB to 20 GB over validity periods of three to thirty days.
