2.2 eConnect Japan

Featured in New York Times and Forbes, eConnect is the most trusted and most reviewed pocket WiFi in Japan. There are 3000 reviews that rate eConnect 5 stars. The company is also incorporated with Japan National Tourism Organization.

What set eConnect Japan apart is good service, for instance, full transparency details of plans and hotspot. They explain the reason they don’t advertise their products by “Unlimited data” is because it is a misleading word used by many other company. The data may be unlimited but at a throttled speed.

Instead, eConnect makes it clear they guarantee some amount of high-speed data. Their basic plan involves 10GB of data at a guaranteed 4G/LTE speed. After the above data is used up, users can access unlimited data at a restricted speed. That plan is the cheapest with unlimited data and the longest battery life, even though you have to compensate a bit for speed. Therefore, it is perfect for short trips or light data users who are looking for a cost-effective plan. However, eConnect suggests using the most popular Premium package for first-time users who haven’t figure how much data allowance they need. For groups of family/ friends, the Monster plan is recommended as it provides a 100GB data load.
