【In-Car Wi-Fi】Say goodbye to data charges! Just plug it in and it's ready to use without monthly fees, so you can relax
If you want to fully enjoy videos and entertainment during road trips or overnight stays in your car, a stable internet environment is essential. That said, using your smartphone for tethering can be a hassle with data limits... In that case, using a portable Wi-Fi device might be a good option!
Affordable & Reliable Car Wi-Fi Router

Whether it's camping in your car or a long-distance drive, you want to enjoy the internet comfortably without worrying about data limits. The "KURUFi (Kuru-High) KD-1" is what I found for such times. It's a cloud WiFi device compatible with a pay-as-you-go communication plan with no monthly fee or contract, and it has a battery-less design that makes it safe to leave plugged in inside the car. This should help alleviate the stress of using the internet while camping or driving.
Simple Plug-and-Play Design

Once it arrives, you just plug it into the power socket in your car to get started. Simply connect to the WiFi using the SSID and password provided on the device. The device has a built-in cable (Type-C) and comes with a Type-C to Type-A adapter. If the outlet is Type-A, you won't need to prepare the adapter.
It can connect up to 8 devices at once. It’s convenient for family trips with smartphones and game consoles. Additionally, if power is available, it can be used by plugging it into a mobile battery or outlet, making it versatile for outings.

Flexible Plan Options

The communication plan is a charge-type with no contract for a monthly fee of 0 yen. It’s a waste-free system where you only use it when you want to and can charge it on the spot when you run low. At the initial purchase, you can choose from 5GB, 10GB, 30GB, 50GB, or 100GB of data capacity, with a validity period selectable between 30 days or 365 days. For additional charging, there are high-capacity plans of 200GB and 300GB available in addition to the initial capacity. You can charge only as much as you need depending on the situation, which seems user-friendly.
2in1 design that allows charging while in use

The device is 2in1, featuring a female Type-C port at the back. By inserting your existing charging cable, you can simultaneously charge your smartphone or tablet while using WiFi. The device supports PD (Power Delivery). With a maximum power supply of 20V/65W, it seems suitable for charging laptops and medium-sized devices.
