Does nextSIM offer unlimited data eSIM for Japan?
nextSIM does not offer a truly unlimited data eSIM for Japan.
The plans that carry “Unlimited” in their names provide a fixed high‑speed data allowance of 1GB or 2GB; after that amount is reached the speed is reduced to 512kbps or 2000kbps.
For travelers who need more data, nextSIM offers larger fixed data plans. A 50GB 30Days Economy plan costs $56.82 USD and a 20GB 30Days Standard plan costs $22.39 USD. These options can be more cost‑effective, especially for users who consume more than the 1‑ to 2‑GB limits on the so‑called unlimited plans.
Does nextSIM offer Japan eSIM with phone number and SMS?
nextSIM does not provide an eSIM plan with a local phone number or SMS capability for Japan.
Only data‑only eSIMs are offered, which allow internet access on 4G or 5G networks.
Travelers can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection to make calls and send messages.
How many data plans does nextSIM offer for Japan?
nextSIM provides 29 single‑country plans and 28 multi‑country plans for Japan, offering a wide range of options. The plans are priced between $2.79 and $1, 316.18, with data caps ranging from 1 GB to 50 GB. Some plans use a daily data‑cap model—giving you a set amount of data for each day of validity—while others use a fixed data‑cap model, delivering a total data allowance for the entire validity period.
