Does ChillaxSIM offer unlimited data eSIM for Japan?
ChillaxSIM does not provide a truly unlimited data eSIM for Japan. All plans labeled “unlimited” in the ChillaxSIM catalogue give a 1GB per day allowance; after that limit the speed is throttled to 5120kbps. If travelers need more data without a day‑by‑day quota, ChillaxSIM offers fixed data plans such as 20GB, 30GB or 50GB for 30 days, each with a reduced speed of 128kbps once the data cap is reached. These fixed‑data options are often more cost‑effective for users whose data usage exceeds the 1 GB/day threshold.
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.
