Frequently Asked Questions

Does ChillaxSIM offer unlimited data eSIM for Japan?

ChillaxSIM does not provide a truly unlimited data eSIM for Japan. The plans that carry “unlimited” in their name actually limit each day to 1GB of high‑speed data; once that amount is reached the speed drops to 5120kbps.

If an unlimited experience is desired, travelers can instead choose one of ChillaxSIM’s fixed data plans. For example, a 50GB data allowance for 30 days costs $48.90, while a 30GB plan for the same period is priced at $30.90, and a 20GB plan for 30 days is $21.90. These fixed plans give a larger amount of data and avoid the speed throttling that applies to the so‑called unlimited offerings.

Does ChillaxSIM offer Japan eSIM with phone number and SMS?

ChillaxSIM does not offer any eSIM plan for Japan that includes a phone number or SMS capability. The provider’s Japan eSIMs are strictly data‑only, so travelers will not receive an inbound or outbound voice number. However, the data connection works with VoIP services such as WhatsApp, Telegram, and iMessage, which can be used for voice calls and messaging over the internet.

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.
