“Amazing speed low latency super local esim”
eSimfly for Japan FAQ
Does eSimfly offer unlimited data eSIM for Japan?
eSimfly offers several unlimited‑data eSIM plans for Japan, ranging in validity from 3 days to 20 days and in price from $6.75 USD to $44.55 USD. The plans travel under the “Japan … Unlimited” names and allow tethering, but note that the speed may be throttled and a Fair Usage Policy is applied, so after heavy use speeds can be reduced. Users who are concerned about potential speed restrictions should contact eSimfly directly to confirm whether a FUP applies and how much data remains usable at normal speed.
Does eSimfly offer Japan eSIM with phone number and SMS?
eSimfly does not provide Japan eSIMs that include a phone number or SMS capability. All eSimfly plans for Japan are data‑only. Travelers can still make voice calls and send messages using VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection.
How many data plans does eSimfly offer for Japan?
eSimfly lists 10 single‑country plans that cover Japan and 38 multi‑country plans that include Japan. The available plans range in price from $1.96 to $100.19 and offer data caps between 1 GB and 100 GB for validity periods from 3 to 365 days. Plans are structured either with a fixed data amount that can be carried over between days or with a daily data cap; 42 plans use the fixed‑data model while 6 use the daily‑cap model.
