CocoRoam for Japan FAQ

Does CocoRoam offer unlimited data eSIM for Japan?

CocoRoam does not provide an unlimited data eSIM plan for Japan. Travelers can choose from fixed‑data options instead, such as the Asia 100GB 30d plan for $113.90 USD, which offers 5G access and covers Japan along with 20 other countries, or the Japan 50GB 7d plan for $26.90 USD, which offers 5G coverage specifically in Japan. Choosing a fixed‑data plan can be more cost effective unless a user is an extremely heavy data consumer.

Does CocoRoam offer Japan eSIM with phone number and SMS?

CocoRoam does not offer a Japan eSIM that includes a phone number or SMS capability. Only data‑only plans are available from this provider for Japan. Travelers who need voice or text can use popular VoIP apps such as WhatsApp, Telegram, and iMessage over the data connection. However, some destinations may block or restrict these services, so it is advisable for travelers to verify that the apps they rely on are accessible in Japan before purchasing a CocoRoam plan.

How many data plans does CocoRoam offer for Japan?

CocoRoam offers 66 single‑country plans and 42 multi‑country plans for Japan, totaling 108 data options. The price range spans $2.50 to $138.00, while the data caps vary from 1 GB to 100 GB, and validity periods extend from 1 to 180 days. Within the catalog, 73 plans feature a fixed data‑cap, and 35 plans provide a daily data cap, giving users a choice between a set amount of data for the entire period or a flexible daily allocation.
