Frequently Asked Questions
Does ViaConecta offer unlimited data eSIM for Japan?
ViaConecta does not offer a truly unlimited data eSIM for Japan; all plans marketed as “Unlimited” provide only 1GB per day, after which the speed drops to a reduced rate (the exact throttled speed is not listed). Travelers who need higher data volumes can choose from fixed‑data options such as a 30GB plan for 30 days, a 20GB plan for 30 days, a 80GB plan valid for 365 days, or a 40GB plan for 180 days. These fixed‑data plans give a larger total allowance and may be more cost‑effective for heavy data users.
Does ViaConecta offer Japan eSIM with phone number and SMS?
ViaConecta does not provide a Japan eSIM that includes a phone number or SMS capability.
Instead, the provider offers only data‑only eSIMs for travel in Japan. Travelers can use those data connections to access VoIP services such as WhatsApp, Telegram, or iMessage for voice calls and messaging.

ViaConecta offers 11 single‑country plans and 11 multi‑country plans for Japan. Plans are split into fixed data caps and daily data caps, with 19 fixed‑data options and 3 daily‑cap options available; fixed plans deliver a set amount of data for the full validity period, while daily‑cap plans reset the data allowance each day. Prices for Japanese plans range from $3.39 to $175.03, and data limits span from 500 MB up to 80 GB, giving travelers a wide variety of choices.
