GulfData for Japan FAQ

Does GulfData offer unlimited data eSIM for Japan?

GulfData does not provide an unlimited data eSIM for Japan. The plans that carry “Unlimited” in their names offer a fixed data allowance of 1GB per day (or a total of 1GB for a single day). Once this limit is reached the speed is reduced to 512kbps, so travelers cannot access high‑speed data without restriction.

Instead, GulfData offers fixed data plans that give larger amounts of high‑speed data before throttling. For example, the Japan 50GB plan is valid for 30 days and costs $34.00 USD, while the Japan 20GB plan is valid for 30 days and costs $16.50 USD. These fixed data plans typically provide a more cost‑effective option for travelers who need substantial data usage.

Does GulfData offer Japan eSIM with phone number and SMS?

GulfData does not offer any eSIM plans for Japan that include a phone number or SMS capability. Travelers who need voice or text services will only have access to data‑only plans from this provider.

Those travellers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging. However, some destinations restrict or block certain apps, so it is advisable to check that the services you rely on are available in Japan before purchasing a GulfData eSIM.

How many data plans does GulfData offer for Japan?

GulfData offers 12 single‑country plans that cover Japan and 43 multi‑country plans that include Japan. The available plans have prices ranging from $3.00 to $197.50, with data caps that span from 1 GB to 50 GB over validity periods of one to 365 days. Some plans are fixed data‑amount plans, while others provide a daily data cap that lets users pull a set amount of data each day, offering flexibility for different usage patterns.
