Frequently Asked Questions
Does eSIMatrix offer unlimited data eSIM for Japan?
eSIMatrix does not provide an unlimited data eSIM for Japan. All plans available list a fixed data allowance, the most common example being the Japan 20 GB – 30 days plan that costs $17.00 USD. For travelers who need more data than the 20 GB option, eSIMatrix also offers a series of “Asia 20 GB” plans that include Japan and additional countries, with validity ranging from 5 to 30 days. Choosing a fixed data plan can be more cost‑effective unless a user requires an exceptionally high level of data usage.
Does eSIMatrix offer Japan eSIM with phone number and SMS?
eSIMatrix does not provide a Japan eSIM that includes a phone number and SMS capability. All eSIMatrix plans for Japan are data‑only, meaning they do not support incoming or outgoing voice calls or SMS messages. Travelers can still communicate using VoIP applications such as WhatsApp, Telegram, iMessage, and others over the data connection, but no traditional phone number or SMS service is offered.
How many data plans does eSIMatrix offer for Japan?
eSIMatrix offers 4 single‑country plans and 16 multi‑country plans for Japan. The plans range in price from about $4 to $41 USD and provide data caps from 3 GB up to 20 GB, with validity periods between 5 and 30 days. Most of the plans are fixed data packages rather than daily data caps, giving travelers clear limits on usage for the duration of their stay.
