Nimbus for Japan FAQ
Does Nimbus offer unlimited data eSIM for Japan?
Nimbus does not offer a truly unlimited data eSIM for Japan. The plans that include “Unlimited” in their names, such as Japan (Unlimited/1 Day), Japan (Unlimited/3 Days), Japan (Unlimited/5 Days), Japan (Unlimited/7 Days), Japan (Unlimited/10 Days), Japan (Unlimited/15 Days), and Japan (Unlimited/30 Days), provide a fixed amount of speed‑rated data—15GB for the specified duration—before the service is capped or stopped. After the allocated data is consumed, speeds may drop to 1 Mbps or the connection may be terminated depending on the specific plan’s conditions.
For travelers who need more data, Nimbus offers fixed‑data plans that list larger caps. Examples include the Japan (60 GB/30 days) plan, which supplies 60GB for 30 days with speeds reduced to 512 kbps after the limit is reached, and various Asia (50 GB/7‑15‑30‑days) plans that offer 50 GB for the respective validity periods. These alternatives can be more cost–effective unless one requires extremely heavy data usage.
Does Nimbus offer Japan eSIM with phone number and SMS?
Nimbus does not provide an eSIM for Japan that includes a phone number or SMS capability. Only data‑only plans are offered by Nimbus for that destination. Travelers who need to make calls or send messages can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these services are accessible in Japan before purchasing.
How many data plans does Nimbus offer for Japan?
Nimbus offers 33 single‑country plans and 25 multi‑country plans for Japan. The available plans range in price from $1.99 to $137.49 and provide between 1 GB and 60 GB of data. Some plans use a daily data cap, limiting the amount of data you can use each day, while others offer a fixed data amount that is available for the entire validity period.
