Does ChillaxSIM offer unlimited data eSIM for Japan?
ChillaxSIM does not provide a plan with truly unlimited high‑speed data for Japan.
All plans that carry the word “unlimited” in their name deliver 1GB of high‑speed data each day; when the daily quota is reached the connection speed drops to 5120kbps.
Travelers who need a larger, predictable data allowance can choose from fixed‑data plans such as Japan Total 50GB for 30 days or Japan Total 30GB for 30 days, both of which are 5G‑capable and offer a single, large data pool with a reduced speed of 128kbps after the quota is exhausted. These options are generally more economical unless a user expects to consume an exceptionally high amount of data.
Does ChillaxSIM offer Japan eSIM with phone number and SMS?
ChillaxSIM does not provide Japanese eSIM plans that include a phone number or SMS capability. The company only offers data‑only eSIMs for Japan. Travelers who want to make voice calls or send text messages can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection.
How many data plans does ChillaxSIM offer for Japan?
ChillaxSIM offers two distinct categories of eSIM plans for Japan: 38 single‑country options and 5 multi‑country bundles. The available plans cover a price range from $1.50 to $70.90 and data caps between 1 GB and 50 GB, with validity periods spanning 1 to 30 days. Some plans provide a fixed data amount for the entire validity, while others apply a daily data cap that resets each day.
