Frequently Asked Questions
Does Giga.Tel offer unlimited data eSIM for Japan?
Giga.Tel does not provide a truly unlimited data eSIM for Japan. All plans labeled as “Unlimited” in the catalogue are limited to 1 GB per day; once the daily quota is reached the data speed is reduced to 512 kbps.
Alternatives are available with fixed data allowances. Examples include a 50 GB plan valid for 30 days, a 60 GB plan for 90 days that also allows tethering and uses 4G/5G networks, and a 90 GB plan that lasts 365 days. Choosing one of these fixed plans can be more cost‑effective, especially for users who consume a large amount of data.
Does Giga.Tel offer Japan eSIM with phone number and SMS?
Giga.Tel provides only data‑only eSIM plans for Japan, so there is no phone number or SMS capability included with its offerings. Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for voice and messaging needs.
How many data plans does Giga.Tel offer for Japan?
Giga.Tel offers 24 single‑country data plans that cover only Japan and an additional 30 multi‑country plans that include Japan. The plans span a price range of $4.49 to $307.99, with data caps between 500 MB and 90 GB and validity periods from one day up to a full year. Among the available plans, some deliver a fixed amount of data for the entire validity period, while others impose a daily data cap that resets each day, providing flexibility for short‑term usage.
