Frequently Asked Questions

Does nextSIM offer unlimited data eSIM for Japan?

nextSIM does not provide a truly unlimited high‑speed data eSIM for Japan. The plans labeled “Un­limited” actually offer a fixed amount of high‑speed data—either 1GB or 2GB per day—after which the speed is throttled to 512kbps or 2000kbps. For travelers who need a larger, unthrottled data allowance, nextSIM offers fixed‑data plans such as the 20GB 30‑day Japan plan priced at $25.32, the 30GB 30‑day GLOBAL Premium plan at $775.21, or the 50GB 30‑day GLOBAL Premium at $1,292.01. These alternatives may be more cost‑effective for heavy data users compared to the daily “unlimited” budget plans.

Does nextSIM offer Japan eSIM with phone number and SMS?

nextSIM does not provide an eSIM for Japan that includes a phone number or SMS service. The provider only offers data‑only plans for travelers in Japan. Users who need voice or text communication can rely on VoIP and messaging applications such as WhatsApp, Telegram, or iMessage, which work over the data connection.

How many data plans does nextSIM offer for Japan?

NextSIM lists 24 single‑country data plans specifically for Japan and an additional 15 multi‑country plans that also include Japan. These plans cover a wide range of options: prices span from about $2.85 to more than $1,299.53, data caps range from 1 GB up to 50 GB, and validity periods vary between 1 and 30 days. Among the Japan‑focused plans, 10 are daily‑cap plans, meaning you receive a set amount of data each day, while 29 are fixed‑cap plans that provide a total data allotment for the entire validity period.
