Before I start my Japan travel blog posts, I’m going to share this 4G WiFi I used when I go to Taiwan and Japan last year. I bought them from Klook. I opted to collect them at the airport since I’m living in Kuching, there is no way I can go to the respective offices in West Malaysia to collect and they also do not provide shipping of the device to this part of Malaysia. Nevertheless, it was effortless to collect at the airport. All you need to do is go the the shop/kiosk located at the airport to collect them.
For Taiwan, I collected it at the arrival floor of the Taipei Taoyuan airport. Just show them your passport, printed or mobile voucher, pay deposit which they will charge to your credit card, then they will return you the deposit when you return the device. It works great without any problem at all. We had at least 5 devices connecting to it each time and battery life was pretty amazing. We charged it every night. This is the one I purchased, 4G WiFi (TW Airport Pick Up) for Taiwan. I do not have photo of it though, forgot to take picture of it.
For Japan, I collected it at KLIA2 at Roaming Man shop. Also fast and easy. Show your proof of purchase and passport. I don’t think there was deposit being collected though(if I recall correctly, it’s was over half year ago! ;p). You will get your unit and you are ready to go! Oh ya, it won’t work in Malaysia even if you switch it on, so save the battery. Only switch it on when you arrive Japan. The battery lasted very long! We were out whole day, using it, not a single problem at all. The signal was good. We only need to charge it after using it for 2 days and we have at least 3 devices connected to it at any one time. We were in Osaka, Kyoto, and Kobe.
This is the one I bought, here’s the link to check it out, 4G WiFi (MY Airport Pick Up) for Japan.
Overall, I have good experience with them. Feel free to check them out at Klook.
