Comparing Pocket WiFi vs Prepaid SIM for your trip to Japan

Why you should prepare your own mobile internet

If you're traveling to Japan for the first time, you shouldn't assume that you'll be able get free WiFi everywhere. Yes, being a highly developed nation, there are areas where you can get on free WiFi. But keep in mind that it is not available publicly at all times. And when you do find a free WiFi network, you may be frustrated to discover that it is not as fast or secure as the ones you enjoy at home.

While Japan is a technologically-forward country and its metropolises are some of the most advanced in the world, tourists are highly encouraged to have their own mobile internet solution to ensure they are able to stay online at all times. If you're planning a trip, it is therefore essential that prior to your visit, you have already figured out which one is better for your needs: a Pocket WiFi or a prepaid SIM (eConnect Japan offers both options by the way.)

Pocket WiFi: Basic Info and Pros & Cons

A device many of you may be familiar with from one of its many different names around the globe. Known to some as MiFi, Portable WiFi, the Dongle, or Mobile Hotspot, this **mobile Internet** device works as a portable router that allows more than one gadget to connect to the World Wide Web at the same time. Although small enough to fit a pocket, it delivers a strong network connection usually found in wired broadband systems.

This may surprise you but Pocket WiFi, in most cases, actually provides much faster internet speed than prepaid SIM cards.

Pocket WiFi is not for sale. Only for rent.


  • Ultra fast 4G / LTE network
  • Large data (GB) allowance
  • Allows multiple devices to connect, usually up to 10 devices
  • Easy set-up (connecting to a WiFi with password)
  • Nationwide network coverage


  • Needs to be returned to the rental provider after your trip
  • Needs to be charged on a daily basis
  • Might need to bring a backup battery to ensure it works for a whole day

Simply put, if you are looking for high speed internet with a larger than most of prepaid SIM data allowance, Pocket WiFi rental is perfect for you.

And the only drawback is that it's for rent and you will have to return it at the end of your trip, just like a car rental. Also, being a portable device, it's an extra gadget for you to carry around and to charge but it should not be a big concern for most of travelers.

We at eConnect Japan provide a free portable battery (power bank) for free of charge to ensure an uninterrupted internet connectivity 24/7 so its battery capacity won't be an issue.

Lastly, Pocket WiFi is perfect for families or groups of people traveling together because it allows for high data use as well as multiple device connectivity. Also, a great option for the solo traveler out there who needs to connect various devices all at once.

Prepaid SIM: Basic Info and Pros & Cons

To ensure reliability and nationwide coverage, eConnect Japan uses SIM cards only from the heavy-duty Docomo.


  • No separate device or battery means less bulk and more mobility
  • Disposable and hassle-free (no need to return after your trip)
