Easy to use, instant connection
I used Ubigi for my recent trip from Australia to South Korea and Japan. It worked flawlessly and I had no issues connecting at both airports on landing. My partner had another service and had so much trouble connecting that he cancelled it and used Ubigi instead

Very easy to research and buy a plan
Very easy to research and buy a plan. Lots of instructions on how to install once purchased and really easy with location based activation as it was ready straight off the plane. No problems in any of the places we’ve been in Japan but we haven’t ventured off the beaten path. Always been good speed.

Easy to install
Easy to install, activate and provides 5g service. I have had to occasionally restart my phone when service is lost, but not a big issue.

Ubigi allows me to instantly be connected once my plane touched down. The service was great no matter where I went around Japan (I went from Osaka to Tokyo). It was also easy to top up when I used too much data. I first tried it back in 2025 and had to use it again because it was good value of my money and I already had a good experience using the service.

Much easier than anticipated
Very easy to set up and a fraction of the price of going over your data allowance from your home provider when travelling abroad
