Are Unlimited WiFi Services Truly Unlimited? Tips for Choosing Japan WiFi

Understanding «Unlimited Data» vs. «Unlimited High-Speed Wifi»

Many companies advertise «Unlimited Data» for their WiFi services without specifying whether the speed will be slowed down. The reality is that, in most cases, the connection speed may be throttled after reaching a certain data limit. Even providers that claim «Unlimited High-Speed» might slow down depending on the time of day (e.g. after 6 pm) or your location (inside a building, tunnel, subway).

To avoid unpleasant surprises, we recommend you thoroughly check provider’s notes and customer reviews before renting a pocket WiFi device or SIM/eSIM.

Key Points to Watch for with Unlimited Data

1. Data Limits on «Unlimited High-Speed WiFi»

Despite being promoted as «unlimited», some WiFi providers actually impose daily or total data limits that trigger speed reductions. If you’re heavy data users, you could exceed these limits.

• Daily Limits: If you exceed a certain amount of data, such as 1 or 3 GB in a single day, your speed may drop. While this is sufficient for messaging or emailing, it’s not enough for streaming videos or playing games.
• Trip Data Cap: Once you hit a total of usage GB in your Japan trip, your speed could drop to 128Kbps. This speed is barely enough for browsing website or surfing SNS, let alone watching videos.
• FUP (Fair Usage Policy): This is a policy that ensure equitable distribution among all users. Once a user surpasses the threshold, the internet speed is decreased to maintain service quality for everyone.

2. Low Connection During Peak Hours

Even if you rent «Unlimited High-Speed WiFi», you might still experience slowdowns on some occasions:

• Peak Hours: Network congestion is common after 6PM. Unfortunately, you likely won’t receive a refund if the speed is inconsistent.
• Location: Signal strength and internet speeds can be weak in certain locations like buildings, underground areas, crowded areas, tunnels or mountainous regions. If those places are in your travel itinerary, this is a factor to consider.

Tips for Choosing the Best WiFi Rental in Japan

When selecting a travel WiFi plan, be sure to:

• Check the specs of pocket WiFi, SIM card or eSIM;
• Read customer reviews, particularly for feedbacks on speed and coverage;
• Confirm the data limits and speed throttling policies.
