How to Rent a Pocket Wifi Device?

Renting a mobile WiFi routern can be a relatively straightforward and stress-free experience if you go about it the right way. All you really need to do to get started is to go to the website of the provider you’re interested in and fill out an application form.

Depending on the service you can choose from the list of options above, you’ll either need to pick up your device at the airport when you arrive in Japan, or you can elect to have it delivered directly to the hotel where you’ll be staying.

Service providers will usually provide you with a set of instructions on how to get set up and start using the WiFi router, so make sure to use these as a reference when connecting any devices like smartphones, laptops, etc. for the first time.

Keep in mind that if you’re staying at an Airbnb, some service providers will not deliver to your residence so you will likely want to book in advance and pick up at the airport when you arrive to avoid any hassle later.

When it’s time to wrap up your Japan trip and head back home, be sure to return any rented pocket WiFi routers to ensure that you aren’t charged any additional fees. Many providers will have pre-paid envelopes supplied that you can use to return the devices or they will have little areas at Japanese airports that you can use to return the device once you prepare to fly back home. The option you choose will depend on the service provider that you chose and signed up with.

Coverage and Network Providers

When traveling to Japan, pocket WiFi routers that utilize 4G and/or LTE networks are the absolutely best choices for ensuring a strong internet connection.

We’ve already paid close attention to these factors for all of the providers we added to this list, so if you choose one of the ones listed above, you’ll be set. That being said, if you decide to do your own research as well, make sure to be mindful of this.

Insurance Options

Sometimes, pocket wifi in Japan offers insurance for the devices that can protect users from expensive compensation fees due to damage or loss. This additional level of coverage can help to remove the worry of being held liable for any unexpected incidents that could happen during the rental period.

It’s important to check with your provider on what their policies are regarding this kind of insurance so you know exactly what is covered and how much it costs. Also be sure to ask what sort of fees can be incurred for lost or damaged WiFi rentals and ensure that the company has a fair usage policy for the devices.

Battery Life and Power Banks

It’s also important to bear in mind the device’s battery life. Most devices should last the majority of the day that you’ll need to use them. Some may last upwards of 20 hours, but be mindful of this when searching for devices.

Inquire with your rental provider about their power bank availability as this can be very helpful if you plan on using the pocket WiFi over extended periods without access to electricity. Power banks often vary between providers and come with their own various charging times and compatibility types. If you know the type of power that your device will need and the cable it uses, you can also plan in advance and pick one up on Amazon to bring with you.

Connecting Multiple Devices

Connecting multiple devices at once – such as phones, tablets, and laptops is extremely important if you’re traveling with multiple people who all will need access to the internet at the same time. You’ll want to make sure everyone is able to share the same internet connection. The devices we listed above all have tons of connected devices allowed at the same time, but be sure to check with the provider before purchasing to ensure it meets your own individual needs.

Navigating Free Wifi Spots in Japan

In Japan, free wifi spots are available periodically to help travelers stay connected on their trip. They may not be the most dependable option, but if you ever find yourself in a desperate need for internet access, sometimes they may have to make do. For a more reliable internet connection though, pocket WiFi rentals are definitely the superior choice. This way you won’t be searching trying to find somewhere to connect your devices out in the wild

When considering what to choose for your journey in Japan, whether you should get a pocket WiFi device, or a SIM card (or eSIM card) – take into account the kind of usage you’ll need and also how many people will need to be connecting to the internet at once. Opting for pocket WiFi will serve people who need access to larger amounts of high speed data on a regular basis and plan on connecting multiple devices at once.

While you can certainly get both a pocket WiFi rental device and a SIM or eSIM card, it’s good to weigh your options and look at your situation to decide what your needs are and what will serve you best.

For long visits, having one or more Japan travel SIM card options could be the more economical choice. That being said, if vacation is on the shorter side, then going with pocket WiFi offers is much more convenient, and having access to unlimited data is a big plus.
