Frequently Asked Questions

Does Keep On Roaming offer unlimited data eSIM for Japan?

Keep On Roaming does not offer a truly unlimited high‑speed data plan for Japan. All plans that carry “Unlimited” in the name are limited to 1 GB per day; once that daily quota is reached the connection speed is throttled.

If a visitor needs more data, Keep On Roaming provides fixed‑data options that may be more cost‑effective. For example, a 20 GB plan valid for 30 days costs $22 USD, a 10 GB plan valid for 30 days costs $19 USD, and a 5 GB plan valid for 30 days costs $15 USD. These plans grant a larger data allowance, though once the set amount is exhausted the speed may drop.

Does Keep On Roaming offer Japan eSIM with phone number and SMS?

Keep On Roaming does not provide any Japan eSIM plans that include a phone number or SMS capability. Only data‑only eSIM options are offered for that destination. Travelers who need voice or messaging services can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection to make calls and send messages.

How many data plans does Keep On Roaming offer for Japan?

Keep On Roaming lists 12 single‑country data plans for Japan and offers 11 multi‑country plans that include Japan.

The single‑country plans range in price from about $7.00 up to $148.00, with data caps varying from 1 GB to 20 GB and validity periods from 1 to 30 days. Multi‑country plans show a similar price spread, often reaching the upper end of the range, and likewise provide data caps from 1 GB to 20 GB across a comparable validity window.

Within their catalogue, plans are divided into fixed‑data‑cap options (14 plans in total) and daily‑data‑cap options (9 plans). Fixed‑cap plans provide a set amount of data that does not reset daily, whereas daily‑cap plans reset at the end of each day and may be suitable for travelers needing predictable usage for short periods. All plans allow tethering where applicable.
